 Case Background

Water Management Services, Inc. (WMSI or utility) is a Class A water utility providing service to approximately 1,776 water customers in Franklin County.  For the year ended December 31, 2004, the utility reported in its annual report operating revenues of $1,419,587, and utility operating income of $269,290.  The utility’s water rates were last established in a rate case by Order No. PSC-94-1383-FOF-WU, issued November 14, 1994, in Docket No. 940109-WU, In re: Petition for interim and permanent rate increase in Franklin County by St. George Island Utility Company, Ltd.

On June 6, 2000, WMSI filed an application, pursuant to Section 367.0822, Florida Statutes, for a limited proceeding to increase its water rates to recover the cost of building a new water transmission main to connect its wells on the mainland to its service territory on St. George Island.  In its petition, the utility stated that it was notified by the Florida Department of Transportation (DOT) that the existing bridge to St. George Island, to which WMSI’s water main is attached, was to be demolished and replaced by a new bridge with an expected in-service date of March 2003.  Upon completion of the new bridge, WMSI would have to make alternative arrangements to provide service to its certificated service area.  The utility’s petition set forth its plan to construct a new main to be attached to the new bridge, along with ancillary modifications to its system, and requested an increase in its rates to provide funding for the proposed construction.

A customer meeting was held at the Franklin County Courthouse in Apalachicola on September 12, 2000, in order to allow the utility’s customers the opportunity to comment on WMSI’s petition.  More than 100 customers attended, and 13 customers made statements.  In general, the speakers believed that the projected cost of the project was excessive and that the utility should have planned for this contingency in such a way as to avoid such a large rate increase.  There was also great concern over the utility’s ability to provide fire protection.

WMSI originally requested that the Commission approve two tiers of temporary increases, to be approved concurrently, described as Phase 1 and Phase 2, in its initial consideration of this matter.  Phase 1 would cover preliminary costs and Phase 2 would cover estimated total costs of the project.  The utility then proposed a true-up, described as Phase 3, which would set final rates after the project was complete and all costs were verified. 

By Order No. PSC-00-2227-PAA-WU, issued November 21, 2000 (consummated by Order No. PSC-00-2405-CO-WU, issued December 14, 2000), the Commission found that construction of the new water transmission main was justified, and that the prudent costs to be incurred by WMSI in this project should be recovered through a three phase mechanism.  Further, the Commission found that replacement of the existing 8-inch main with a 12-inch water main was prudent, and that the used and useful percentage for the new main should be 100 percent.  The Commission also approved the prudence of constructing a new line from Well No. 1 to Well No. 4 in connection with the replacement project.  In addition, the Commission approved a Phase 1 increase and deferred consideration of a temporary Phase 2 increase until the utility filed more complete and detailed cost information.  The approved Phase 1 increase was 11.3 percent, or an annual revenue increase of $82,707.

On May 14, 2003, WMSI filed a Supplemental Petition for Limited Proceeding (supplemental petition), requesting revised rates for the Phase 2 rate increase.  In its supplemental petition, the utility stated that numerous changes had occurred since the filing of the original petition.  First, the projected bridge in-service date was changed from March 2003 to October 2003.  Second, the estimated capital cost of the new transmission main and the other approved work on the mainland had decreased.  Third, WMSI had obtained financial support from the State Revolving Fund (SRF) loan program administrated by the Department of Environmental Protection (DEP).  Finally, WMSI’s eminent domain case was unsuccessful.

Since the net effect of the above mentioned changes substantially reduced the total project cost, WMSI requested the inclusion of fire flow protection improvement measures in its supplemental petition for limited proceeding.  The utility stated that fire flow protection is an issue of great importance to the utility’s customers, as communicated at the customer meeting.  The overall rate increase requested in the supplemental petition was designed to generate annual Phase 2 revenue of $568,657 above the expected revenue from the previously approved Phase 1 rates, or an additional increase of 50.2 percent.

By Order No. PSC-03-1005-PAA-WU (Phase 2 PAA order), issued September 8, 2003, the Commission approved a Phase 2 revenue requirement of $490,959, or an increase of 42.1 percent in base facility and gallonage charges.  The Commission also approved the utility’s request to include the cost of improved fireflow protection in this proceeding, and established a depreciable life of 35 years for the portion of WMSI’s transmission main attached to the new bridge.

On September 29, 2003, the Office of Public Counsel (OPC) timely filed a Petition on Proposed Agency Action.  OPC objected to that portion of the utility’s plan which called for removing the existing 150,000 gallon elevated water storage tank and replacing it with a new 200,000 gallon tank.

On September 29, 2003, the utility timely filed a Petition on Proposed Agency Action.  WMSI stated that its petition was in response to its understanding that OPC was also filing a protest.  WMSI’s petition addressed the rate case expense that would be incurred as a result of a formal hearing.

On May 28, 2004, WMSI and OPC filed a Joint Motion Requesting Commission Approval of Settlement Agreement to address both parties’ protests.  The substance of the settlement agreement was that, in lieu of replacing the storage tank, the utility would complete the looping of the water mains that serve the service territory from Bob Sikes Cut to the state park.  By Order No. PSC-04-0791-AS-WU, issued August 12, 2004 (Settlement Agreement Order), the Commission approved the settlement agreement.

On October 14, 2004, the utility filed its Petition for Approval of Phase 3 Final Rates (the final petition).  This is staff’s recommendation on final rates for this docket.  The Commission has jurisdiction pursuant to Sections 367.081 and 367.121, Florida Statutes


Discussion of Issues

Issue 1:  

What is the appropriate final revenue requirement for this limited proceeding?

Recommendation

 The appropriate final revenue requirement for this limited proceeding is $1,368,807.   (Kyle, Edwards)

Staff Analysis

 In the final petition, WMSI requested final water rates which, by its calculation,  would generate annual revenues of $1,387,480.  The utility’s request for final rates was based upon a formula which included factors for the total expenditures for the supply main and fire flow improvements.  These expenses included the interest rate applicable to construction financing, depreciation and property taxes on the new construction, rate case expense for the limited proceeding, increased property insurance costs, the expense of annual audits required by the lender, amortization of the residual value of the retired supply main, and regulatory assessment fees (RAF) associated with the increased revenue.  The utility’s calculation is summarized as follows:

WMSI’s calculation methodology is similar to the approach approved by the Commission in the Phase 2 PAA Order.  Staff has reviewed the information submitted by the utility in support of its calculation and believes that the methodology is still reasonable, with adjustments as discussed below.  The utility attached three schedules to the final petition providing details of its calculations.  WMSI also responded to several formal and informal requests from staff for additional data.  As ordered by the Commission in the Phase 2 PAA Order, staff conducted an audit of the expenditures claimed by the utility in the final petition.  On May 4, 2005, OPC submitted a letter expressing seven specific concerns about the utility’s filing.  On May 9, 2005, WMSI submitted a letter responding to OPC’s concerns.  Staff will first address six of the specific areas of concern addressed in OPC’s letter, then provide additional analysis and adjustments.  The other area of concern included in OPC’s letter will be addressed in staff’s analysis of the utility’s proposal for a true-up in Issue 2.

Improvements to Office Building

OPC’s first concern was that the final petition included costs associated with improvements to its office building on the island in the amount of $287,231.  OPC believes that these costs are outside of the scope of the limited proceeding, that they have not been mentioned by the Commission in any previous orders in this docket, and that these costs have not been verified and reviewed for prudence by the staff audit.

WMSI responded that the improvements were included in the fire protection improvements approved by the Commission in the Phase 2 PAA Order.  Although described as “island office improvements” in the final petition, the $287,231 represents an expenditure included in “other plant improvements” in the Supplemental Petition.  WMSI stated that all of the high service pumps, the electrical equipment, and the generator are located in the office building structure.  The utility explained that the building required substantial renovation in order to accommodate the operational requirements of the service improvements which are the subject of this proceeding, to improve safety and working conditions for WMSI employees, and to improve the appearance of the building.

The staff audit report, issued March16, 2005, did not contain any exceptions with respect to the expenditures which are the subject of this limited proceeding.  On May 9, 2005, the staff engineer made a physical inspection of the utility’s water facilities.  In his report dated May 16, 2005, the staff engineer stated that he had reviewed the structural improvements to the utility’s plant and the fire flow protection system.  The improvements observed included a new electrical room, a new generator and generator room, a new chlorination room, a new spare parts room, and a new roof for the expanded building.  The engineer’s report indicated that all of the improvements appear to be prudent and within the scope of this limited proceeding, with the possible exception of a second floor area created by the roof expansion.  This area includes glass French doors, large windows, decking and vinyl siding.  The utility stated that the area could be used for storage; however, staff’s observation was that it was not currently being used or complete.

In response to staff’s request, WMSI provided a detailed breakdown of the costs of the building improvements.  The cost of the decking and other improvements which were questioned by the engineer was $37,310.  The utility reiterated its belief that all of the first floor improvements were integral to the implementation of the improvements which are the subject of this limited proceeding.  Staff agrees with this assessment, but believes that the second floor improvements go beyond what the Commission approved in the Phase 2 PAA Order.  Therefore, staff recommends that $37,310 be removed from the total cost used in the utility’s calculation.

Staff also recommends that the cost of the second floor be removed from the “net cost” component of the utility’s calculation.  Using the 33 year life assigned by the utility to the building improvements, staff has calculated one-half year depreciation for the second floor to be $605.  Accordingly, staff’s recommended adjustment to “net cost” is a reduction of $36,705.

Depreciation Expense For Retired Supply Main

In its May 4, 2005 letter, OPC observes that the utility does not appear to have made any adjustment to remove depreciation expense for the retired supply main in its calculations.  In its response, the utility agrees with this assertion, and states that the depreciation expense included in the final petition includes only the expense related to the new construction.

Staff believes that the thrust of the utility’s calculation of additional revenue required is, appropriately, the net increase in costs incurred for the replacement of the supply main and for the fire flow improvements.  Therefore, staff believes that it is appropriate to net the depreciation for assets which are being replaced and are no longer in service with the depreciation expense for the new construction.

Staff notes that, in Schedule 2, page 2 of 3, of the final petition, WMSI assigned a 32 year life to the largest single component of the retired assets ($298,469 placed in service in 1985).  Rule 25-30.140(2)(a), Florida Administrative Code, prescribes a 35 year life for supply mains recorded in NARUC Account 309 for Class A and B utilities.  In response to a staff request, the utility stated that WMSI was a Class C utility in 1985, and had used the prescribed 32 year life prescribed for Class  C utilities.  Staff believes that, because the utility is now subject to the Class A and B guidelines, it is appropriate to use a 35 year life for purposes of this calculation, because the approved revenue adjustment will relate to future periods.  The utility calculated the annual depreciation of the retired assets as $9,791, but did not include that amount as an offset to the depreciation expense for the new construction.  Using a 35 year life for all of the retired assets, staff calculates the annual depreciation as $8,992.  Staff recommends that the utility’s formula be adjusted to subtract that amount from the calculated depreciation on the new construction.

Depreciable Life for New Supply Main

In its final petition, the utility requests that the Commission approve a 30 year life for the portion of the new supply main which is attached to the bridge and exposed to air and salt spray.  In the Supplemental Petition, the utility had described this main as a transmission main, for which the guideline depreciation rate would be 40 years.  The utility requested a reduced depreciable life, and the Commission approved a 5-year reduction from the guideline rate.  In the final petition, the utility points out that the asset in question is actually a supply main, for which the guideline life is 35 years.  WMSI states that the characterization of the main as a transmission main was simply a clerical error, and correctly notes that staff did not notice the error in the course of its analysis of the Supplemental Petition.  The utility states that the same factors which were considered by the Commission in approving a 5-year reduction in the life of the exposed portion of the main are still relevant, and requests approval of a 30 year life for the exposed supply main and a 35 year life for the buried portion of the main.

In its May 4, 2005 letter, OPC states that “the utility changed the Commission approved depreciation rate for the water main now called a supply main from 35 to 30 years.”  OPC believes that this is an untimely motion for reconsideration of a final order, that the Commission fully considered the issue during the Phase 2 proceeding, and that a 35 year life is reasonable and should be used.

In its response to OPC’s letter, WMSI states that it is only asking the Commission to recognize that there was an error in nomenclature, and to apply its previously approved adjustment for adverse environmental conditions to the correct category.  The utility cites to Sunshine Utilities v. Public Service Commission, 577 So.2d 663 (Fla. 1st DCA 1991), in which the Court upheld a Commission order which properly corrected a rate base computation in a prior Commission order issued five years earlier which required the utility to make refunds, holding that the Commission “has the authority to determine whether there are mistakes of this character in its prior orders and has a duty to correct such errors.”  Id. at 665.

Staff, after reviewing the above case and considering the parties’ arguments, believes that the utility’s request should be approved.  The final phase of this proceeding was always intended to consider all of the relevant facts in setting final rates.  The main in question is clearly a supply main, properly assigned to NARUC Account 309, for which the guideline life is 35 years.  Staff believes that the rationale employed by the Commission in approving a 5-year reduction for the exposed portion of the main is still appropriate, and that the Commission has the authority to approve this correction.

Amortization of Retired Supply Main

WMSI included in its final petition a provision for amortization of the undepreciated portion of the supply main which was replaced.  The calculation of the requested amortization amount of $14,631 was provided in Schedule 2, page 2 of 3.  In its May 4, 2005 letter, OPC notes that this factor was not included in the Phase 2 proceeding.  OPC also expressed concern with the calculation of the amortization, the source of the figures used in Schedule 2, and the depreciation lives used.

In its response to OPC’s letter, the utility correctly points out that the amortization could not have been included in the prior phases of this proceeding, because the date of the retirement would not have been known at that time.  Further, WMSI states that the calculation was performed in accordance with Rule 25-30.443(9), Florida Administrative Code, and that the source of the figures was the company books, which were subject to audit by staff.

In response to staff questions about the calculation of the amortization amount, the utility stated that none of the retired property was contributed, and that the assets were not salvaged because the cost of preparing them for salvage would have exceeded the amount which might have been received.  As noted in the previous discussion of depreciation expense for the retired main, the utility used a 32 year life for the portion of the retired assets placed in service in 1985.  Staff believes that the appropriate life for purposes of this calculation is 35 years.  Staff also questioned the discrepancy between the retirement date of December 31, 2003, used in WMSI’s calculation, and the fact that the retirement was included in the utility’s 2004 Annual Report.  The utility responded that the actual date that the retirement was recorded in its books was February 27, 2004.  WMSI provided an updated calculation of an amortization amount of $14,298, using a 35 year life for all of the assets and February 27, 2004, as the retirement date.

Staff has reviewed the supplemental data provided by WMSI, and believes that the revised calculation is in accordance with Rule 25-30.443(9), Florida Administrative Code.  Accordingly, staff recommends that the calculation of revenue requirement for final rates should include amortization of undepreciated prudently retired plant in the amount of $14,298.

Incremental Property Insurance

In its May 4, 2005 letter, OPC questions whether the utility has provided support for the amount of the increase in property insurance cost.  Further, OPC notes that the insured cost of the old main as stated on Schedule 2, page 3 of 3 ($113,000) differs from the total cost of the retired assets shown on Schedule 2, page 2 of 3 ($314,709).

In its response to OPC’s letter, WMSI states that the information provided in the final petition was taken from a summary of present and subsequent premiums provided by the utility’s insurance agent, and that the information was available to the staff auditor, who made no comment in the audit report.  In response to staff’s request for additional information, the utility provided copies of actual Common Policy Declarations and Notices of Acceptance detailing the property covered and the applicable premiums, as well as documentation of payment of the premiums.  The utility also provided a copy of the original memorandum which was the basis for the amount of increased insurance cost included in the final petition.  WMSI stated that it is not known why the insured value of the old main was less than the cost reflected on the books; however, the utility noted (and the documents provided supported) that the amount of the premium on the old assets was $147, as reflected on Schedule 2, page 3 of 3.

Staff has reviewed the information provided and the utility’s explanation, and staff believes that WMSI’s requested amount, $8,253, should be included as incremental insurance cost in the calculation of the revenue requirement for final rates.

Used and Useful Analysis of Transmission and Distribution Mains

In its May 4, 2005 letter, OPC asks whether staff has considered the “used and usefulness of additional island water distribution mains added to WMSI’s system, since the Commission’s last order in this limited proceeding.”  In a follow-up memorandum, OPC stated its belief that “a used and useful analysis should be performed on all water distribution pipes installed on the island since the ‘first’ Commission Order was issued in this Limited Proceeding, not the ‘last’ Commission Order issued in this proceeding.  This analysis should be performed on all of the additions to the WMSI’s island transmission and distribution mains since the inception of this limited proceeding.”

WMSI’s response stated that, in the Phase 2 PAA Order, the Commission found the utility’s proposal for fire flow improvements including 17,700 feet of 6 inch and 8 inch mains, a new 200,000 gallon elevated storage tank, high speed service pumping, an emergency generator and other plant improvements to be prudent.  Further, the utility noted that the settlement agreement resolving the protests of the Phase 2 PAA Order called for using the money originally approved for the new storage tank to be spent instead to complete the looping of the water mains.  In the final petition, WMSI stated that a total of approximately 35,000 feet of 6 inch and 8 inch distribution lines were installed pursuant to the Phase 2 PAA Order and the settlement agreement.  The utility’s response to OPC’s letter and memorandum noted that the Commission accepted the settlement agreement, and by inference, approved the prudence of all of the new mains.  WMSI explained that the lines were not installed for the sole purpose of providing potable water to individual lots, because this was already being done by existing lines.  The utility reiterated its belief that the new lines, “roughly half of which have been designed and installed at the request and agreement of OPC, are used and useful in the provision of the enhanced fire protection service and capacity.”

Staff agrees with the utility’s assertion that the prudence of the installation of the transmission and distribution lines included in the final petition was established by the Phase 2 PAA Order and the subsequent settlement agreement.  Pursuant to their review of the utility’s expenditures related to this limited proceeding, the staff auditors did not state any exceptions to WMSI’s final listing and categorization of plant additions as stated in Schedule 2, page 1 of 3.  Accordingly, staff believes that no used and useful adjustment should be made with respect to the transmission and distribution mains included in the final petition.

Rate Case Expense

In its final petition, WMSI included a request for recovery of the cost of pursuing this limited proceeding.  In Schedule 2, page 3 of 3, the utility provided details of actual and projected expenses totaling $74,043, of which the utility is including 25 percent ($18,511) in its calculation of additional revenue requirement.  In response to staff’s request, WMSI provided copies of invoices in support of the amounts claimed.  Staff has reviewed the data submitted and believes that the utility’s request is reasonable, with one exception.  The utility included $2,100 in legal fees from Nicholas Yonclas, P.A. for “legal representation regarding water tower.”  Staff’s review of the invoices provided by the utility indicates that this representation relates to the protests of the Phase 2 PAA Order and the resulting negotiated settlement agreement.  In the Settlement Agreement Order, the Commission ruled that “both Petitions shall be deemed to be resolved, with both parties bearing their own expenses associated with this proceeding (OPC on behalf of the customers and the shareholders of the company on behalf of WMSI).”  As a result of this agreement, staff believes that the legal fees for the representation by Nicholas Yonclas, P.A. should not be included in the cost of expense of pursuing this limited proceeding.  Accordingly, staff recommends a reduction in the amount of $525 (25 percent of $2,100) to the utility’s calculated expense of pursuing the proceeding.

Summary of Revenue Requirement Calculation

In Schedule 1, page 2 of 3, of the final petition, WMSI provided details of billing units and consumption for the year ended June 30, 2004, along with a calculation of the revenue expected to be generated by those billing determinants at the rates approved in Phase 2 of this proceeding.  The expected total revenue calculated by the utility was $1,322,599, which included $486,259 of revenue resulting from the excess of the approved Phase 2 rates over the rates in effect prior to the filing of this limited proceeding.  As noted above, the utility calculated a final additional revenue requirement of $551,140, or an increase of $64,881 over the additional revenue provided by the Phase 2 rates.  WMSI’s total final revenue requirement request was $1,387,480, an increase of 4.9 percent over the total Phase 2 revenue estimate of $1,322,599.

The billing determinants provided in Schedule 1, page 2 of 3, reflected total consumption of 175,747,000 gallons; however, in its response to a staff data request, the utility provided a revised total of 178,638,000 gallons along with some changes in billing categories.  Using the utility’s revised figure, staff recalculated the excess of revenue from Phase 2 rates over pre-filing rates as $489,584.  As shown in Table 2, staff’s recommended adjustments to WMSI’s calculation of total final additional revenue requirement reduced that amount from $551,140 to $537,163.  The excess of this amount over staff’s recalculated additional revenue provided from Phase 2 rates is $47,579.  Adding this amount to the utility’s estimated total Phase 2 revenue ($1,322,599) results in a tentative final revenue requirement of $1,370,178.

As discussed in Issue 5, staff has recommended a repression adjustment of 2.2 percent.  To calculate the impact of this adjustment on the revenue requirement in rate cases, staff normally makes an adjustment to reduce purchased power and chemicals included in the Operation and Maintenance (O & M) expenses that are part of a utility’s filing.  In this proceeding, the utility has not filed a detailed description of its O & M expenses; however, the staff audit included an examination of WMSI’s O & M expenses for the year ended June 30, 2004.  The total amount of purchased power and chemicals, per the staff audit report, was $59,867.  For the purpose of calculating the revenue requirement repression adjustment, staff multiplied this amount by 2.2 percent, then applied a 4.5 percent RAF expansion factor, resulting in an adjustment of $1,371.    Accordingly, staff’s recommended final revenue requirement for this proceeding is $1,368,807.  Staff’s recommended adjustments are summarized in Table 2.

Issue 2:  

What true-up mechanism, if any, should be approved to adjust for differences between revenues collected and recoverable expenses incurred from the inception of this limited proceeding through the test year?

Recommendation

 WMSI’s final rates should be decreased by 7.6 percent during the first twelve months that final rates approved in this proceeding are in effect in order to return to ratepayers revenues collected during Phase 1 and Phase 2 of this proceeding in excess of the actual incremental costs incurred by the utility.   (Kyle)

Staff Analysis

 In its final petition, WMSI requested that it be allowed to collect a surcharge of $72,957 from ratepayers during the first twelve months that final rates are in effect.  The utility stated that the Phase 2 rate increase went into effect in September 2003, on the assumption that all of the constructed plant would go into service in the first half of 2004.  The utility stated that, in fact, some of the new construction was placed in service as early as January 2001, and that the calculation of depreciation accrual should begin at the actual in-service date.  The utility also noted that it was required to fund a one-time reserve payment of $209,785 in 2003 in conjunction with the construction loan from DEP.

The utility’s original petition proposed that “to the extent that the additional revenues produced by the Phase I and Phase II rates either over- or under-recover the actual additional revenue requirement associated with the project during those time periods, the Phase III rates would be subject, for the first twelve months they are in effect, to a credit or surcharge in the amount necessary to effect a true-up.”  In the Phase 2 PAA Order, the Commission held that the approved Phase 2 rates were “held subject to over-collection with interest pending the final decision in this docket.”

Schedule 4 of the utility’s final petition provides detail of interest, depreciation and rate case expense incurred from the inception of this limited proceeding through June 30, 2004, including the timing of the expenses.  These amounts, along with the reserve payment, are compared with a calculation of the cumulative total revenue collected as a result of the Phase 1 and Phase 2 rate increases.  WMSI concludes that the revenue required to fund the expenses is greater than the revenue collected by $72,957.

In its May 4, 2005 letter, OPC notes that the cost of funding the DEP loan reserve was not included in the Phase 1 or Phase 2 revenue requirements, and states that it does not believe that this cost should be included in determining whether a refund or surcharge is appropriate.  In its response to OPC’s letter, WMSI states that the reserve payment was addressed in the Supplemental Petition, and that it is an appropriate consideration for true-up because it was a cash expense incurred during the period in question.  Further, the utility argues that “if the projected interest to be earned on the required cash reserve over twenty years is being included as part of WMSI’s operating revenue, then it is only fair and appropriate to include the interest cost to WMSI for the cash required to fund this reserve for the twenty year period.”

Staff notes that the issue of the loan reserve payment was considered by the Commission in Phase 2 of this proceeding.  In the Phase 2 PAA Order, the Commission stated that:

We also computed the annual revenue increase projected at the approved Phase 2 rates, less property taxes, as $415,977 ($490,959 - $74,982).  We compared this amount with the total of the utility’s first two payments on the SRF loan ($419,608, per Exhibit A of the supplemental petition).  We believe that the additional revenue to be received from Phase 2 rates is sufficient to meet the utility’s needs, in view of the fact that the accrued property taxes will not be payable until November 2004.

Staff notes that, in the final petition, WMSI’s calculation of additional of Phase 2 revenues collected was $486,259.  As stated in the preceding issue, staff recalculated this amount as $489,584, based on revised billing determinants.  A comparison of this amount with the approved Phase 2 revenue requirement of $490,959 would indicate that the utility did not experience an unexpected shortfall of revenue from Phase 2 rates.

In Schedule 3, page 2 of 2, of the final petition, the utility calculates the effective interest rate of the DEP loan as 3.32 percent.  In Schedule 3, page 1 of 2, this amount is then used in a calculation of an overall weighted interest rate of 3.48 percent for financing the construction which is the subject of this limited proceeding.  Staff notes that the calculation on Schedule 3, page 2 of 2, includes a factor for amortization of the loan reserve.  This is consistent with the effective interest rate calculation approved by the Commission in the Phase 2 PAA Order.  Staff does not believe that it is appropriate to include the reserve as a separate cost for purposes of calculating a true-up, while at the same time including the amortization of the reserve in the calculation of the effective interest rate used in calculating the final revenue requirement.  Accordingly, staff recommends that the reserve payment of $209,785 not be included in the true-up calculation.

The utility’s true-up calculation in Schedule 4 reflected a “total revenue requirement through 6/30/04” of $727,091, including the loan reserve payment.  WMSI calculated a “cumulative total collected at phased rates” of $654,134.  Staff has reviewed the utility’s calculations and believes that they are reasonable, with the exception of the loan reserve payment.  Subtracting the loan reserve payment from the utility’s total revenue requirement reduces that amount to $517,306, which would result in an over-collection of $136,828.  As a test of reasonableness, staff reviewed the earnings and cost of capital reported in the utility’s annual reports for the years 2000 through 2003.  WMSI has no positive equity; therefore, the cost of capital consists of debt and customer deposits.  After adjusting the cost rate on customer deposits to the Commission standard 6 percent for each year, staff compared the utility’s reported rate of return with its reported cost of capital for each year, and noted that, for all of the years except 2001, the utility was earning slightly more than 1 percent below its cost of capital.  Staff calculated the additional revenue (grossed up for RAF) which would have been required to bring the utility’s earnings within one percent of its reported cost of capital for each year.  Staff’s analysis is summarized in the Table 3.

Staff believes that it is reasonable to offset the total net under earnings reflected in the utility’s annual reports, $32,864, against staff’s previously calculated over-collection of $136,828, resulting in a net over-collection of $103,964.  Although no specific true-up mechanism has been approved by the Commission in the first two phases of this proceeding, staff believes that it is reasonable to return the over-collection to current customers by means of a credit over the first twelve months during which the final rates are in effect.  The over-collection represents 7.6 percent of staff’s recommended final revenue requirement of $1,368,807.  Accordingly, staff recommends that the final rates approved in this proceeding be reduced by 7.6 percent for the first twelve months that the rates are in effect.  These reduced rates are shown in Schedule 1 of this recommendation.


Issue 3:  What are the appropriate test year billing determinants before repression?

 

Recommendation:  The appropriate test year billing determinants before repression are 24,465 equivalent residential connections (ERCs) and 178,637,000 gallons.  (Lingo)

 

Staff Analysis:  According to the utility’s final petition, the utility reported test year billing determinants of 23,367 ERCs and 175,747,000 gallons.  The utility’s requested ERCs was based on its statement that effective November 2004, metering at the State Park would change, eliminating numerous smaller meters and replacing them with a 6” turbine meter; however, as of April 2005, almost one year after the end of the test period, this change has not yet occurred.  Staff believes it is inappropriate to set rates on the ERCs contained in the utility’s filing.  Staff’s calculated test period ERCs are based on a compilation of the utility’s monthly reports which have been filed in compliance with a prior Commission Order.  (See  Order No. PSC-00-2227-PAA-WU, issued November 21, 2000 in Docket No. 000694-WU, In Re:  Petition by Water Management Services, Inc. for limited proceeding to increase water rates in Franklin County, p. 14.)  In addition, staff used residential billing analysis data, including the reclassification of 180 bills from the residential to the nonresidential class, which was provided by the utility in response to a staff data request.  Staff found consumption discrepancies between the utility’s filing, billing analysis data, and the consumption that results from a compilation of the above-referenced monthly reports.

Staff’s analysis of the appropriate test year billing determinants is contained on Attachment A.


Issue 4:  What is the appropriate rate structure for this utility?

 

Recommendation:  The appropriate rate structure for this utility is a three-tier inclining-block rate structure.  The appropriate usage blocks should be set for monthly usage of: 1) 0 – 8 kgals; 2) 8.001 – 15 kgals; and 3) for usage in excess of 15 kgals.  The appropriate rate factors are 1.0, 1.25 and 1.5, while the appropriate base facility charge cost recovery percentage should be set at 40%.  (Lingo)

 

Staff Analysis:  The utility’s current rate structure is the traditional base facility charge (BFC) / uniform gallonage charge rate structure.  Under this usage-sensitive rate structure, customers are charged a monthly BFC of $33.06, plus $3.13 for each 1,000 gallons (kgal) used during the month.  The utility’s current rates were approved as a result of its Phase 2 filing in this case. 

 

At the customer meetings held on September 12, 2000 during Phase One of this proceeding, several customers mentioned their preference for a rate structure with a greater emphasis placed on usage in order to reflect the different consumption habits of permanent residents versus renters.  However, because the utility’s Phase One increase in the instant docket was treated as an emergency, and because staff did not have sufficient customer usage data at that time, the Commission approved a continuation of the utility’s BFC / uniform gallonage charge rate structure, but ordered that the utility’s current rate structure be examined in Phase Three of  this case.  (See Order No. PSC-00-2227-PAA-WU at pp. 13-14.) 

 

Staff’s rate structure analysis and recommendation is contained on Attachment B.


Issue 5:  Is a repression adjustment appropriate in this case, and, if so, what is the appropriate adjustment to make for this utility?

 

Recommendation:  Yes, a repression adjustment is appropriate.  Residential consumption should be reduced by 2.6%, resulting in a consumption reduction of approximately 3,913.6 kgals.  The resulting total water consumption for ratesetting is 174,723.1 kgals, which represents a 2.2% reduction in overall consumption.  In order to monitor the effects of both the changes in revenue and rate structure, the utility should continue filing the monthly reports that were ordered in Order No. PSC-00-2227-PAA-WS.  These reports should be continued for a period of two years, beginning the first billing period after the approved rates go into effect.  (Lingo)

 

Staff Analysis:  Absent direct, comparable data from our database of utilities receiving price increases and decreases, staff utilized the proportional equation approach to calculate the recommended repression adjustment, which is consistent with Commission practice.  (See  Order No. PSC-01-2385-PAA-WU, issued December 10, 2001, in Docket No. 010403-WU, In Re: Application for staff-assisted rate case in Highlands County by Holmes Utilities, Inc., p. 22; Order No. PSC-02-1168-PAA-WS, issued August 26, 2002, in Docket No. 010869-WS, In Re: Application for staff-assisted rate case in Marion County by East Marion Sanitary Systems, Inc., p. 40.)  Staff’s recommended rate structure results in pre-repression price decreases below 10 kgal and nominal price increases from 10 kgal to 15 kgal; therefore, no repression adjustment is warranted for consumption less than 15 kgal.

 

            The average monthly consumption for those customers using greater than 15 kgal is approximately 33.5 kgal.  This level of consumption corresponds to a pre-repression price increase of approximately 40.3%.  Staff has found that a price increase of 33.33% leads to a 6.98% reduction in consumption.  These relationships may be used to solve for the anticipated consumption reduction as follows:

 

              33.33% water-only increase                           =            40.27% pre-repression price increase

              -6.98% consumption reduction                                      X% anticipated consumption reduction

 

                                                          X% = Repression = -8.43%

 

                                           Residential kgals > 15 kgal                             46,411.000

                                           x  Repression percent                                      -8.43%

                                           =  Residential kgals repressed                      -3,913.555

 

                                           Residential kgals repressed                            -3,913.55

                                           /  Total Overall kgals                                      178,636.7

                                           =  Overall repression                                     -2.2%

 

Based on the foregoing, a repression adjustment is appropriate.  Residential consumption should be reduced by 2.6%, resulting in a consumption reduction of approximately 3,913.6 kgals.  The resulting total water consumption for ratesetting is 174,723.1 kgals, which represents a 2.2% reduction in overall consumption.  In order to monitor the effects of both the changes in revenue and rate structure, the utility should continue filing the monthly reports that were ordered in Order No. PSC-00-2227-PAA-WS.  These reports should be continued for a period of two years, beginning the first billing period after the approved rates go into effect.


Issue 6:  What are the appropriate rates for this utility?

 

Recommendation:  The appropriate water monthly rates are shown on Schedule No. 1.  Excluding miscellaneous service revenues, the recommended water rates are designed to produce revenues of $1,368,807.  The utility should file revised tariff sheets and a proposed customer notice to reflect the Commission-approved rates.  The approved rates should be effective for service rendered on or after the stamped approval date of the revised tariff sheets pursuant to Rule 25-30.475(1), F.A.C.  In addition, the rates should not be implemented until staff has approved the proposed customer notice.  The utility should provide proof of the date the notice was given no less than 10 days after the date of the notice.  (Lingo, Kyle)

 

Staff Analysis:  As discussed earlier, the water revenues to be recovered through rates are $1,368,807.  As discussed in Issue 3, staff recommends that the appropriate billing determinants for ratesetting are 24,465 ERCs and 178,637 kgals.  As discussed in Issue 4, staff recommends that the appropriate BFC cost recovery percentage is 40%.  As discussed in Issue 5, staff recommends that the appropriate repression adjustment is 3,913.6 kgals.  Therefore, the resulting monthly rates are shown in Schedule No. 1.

 

            Staff’s recommended increase in revenue requirement is $46,208 (approximately 3.5% over Phase 2 rates, and approximately 64.7% over pre-filing rates).  Approximately 40% (or $552,062) of the revenue requirement is recovered through ERCs, while approximately 60% (or $816,746) represents revenue recovery through the consumption charges.

 

            The utility should file revised tariff sheets and a proposed customer notice to reflect the Commission-approved rates.  The approved rates should be effective for service rendered on or after the stamped approval date of the revised tariff sheets pursuant to Rule 25-40.475(1), F.A.C.  The rates should not be implemented until staff has approved the proposed customer notice.  The utility should provide proof of the date notice was given no less than 10 days after the date of the notice.

 

            As discussed in Issue 4, the utility has a seasonal customer base, and, in the utility’s 1994 rate case, the Commission approved a rate design more heavily weighted to the BFC to increase cash flow during the utility’s off-season.  However, as also discussed in Issue 4, staff’s recommended BFC in the instant case represents an approximate 32% reduction from the current BFC. 

 

Staff prepared a fixed cost recovery analysis in order to determine whether the final recommended rates would cover the utility’s monthly fixed costs.  This analysis, contained in page 1 of Attachment C, demonstrates that staff’s final recommended rates not only provides the utility fixed cost recovery, but generates approximately $13,000 in excess of the fixed monthly costs.  As recommended in Issue 2, staff is recommending a credit of 7.6 percent to be reflected as reduced rates for a period of one year.  A similar fixed cost analysis, contained in page 2 of Attachment C, demonstrates that, with the reduced rates for one year, the utility continues to cover its fixed costs by approximately 10%.


Issue 7:  

What is the appropriate amount by which water rates should be reduced four years after the established effective date to reflect the removal of amortized rate case expense, as required by Section 367.0816, Florida Statutes?

Recommendation

 The water rates should be reduced as shown on Schedule 1 to remove $17,986 in rate case expense amortization, grossed-up for regulatory assessment fees.  The decrease in rates should become effective immediately following the expiration of the four-year rate case expense recovery period, pursuant to Section 367.0816, Florida Statutes.  The utility should be required to file revised tariffs and a proposed customer notice setting forth the lower rates and the reason for the reduction no later than one month prior to the actual date of the required rate reduction.  (Kyle)

Staff Analysis

 Section 367.0816, Florida Statutes, requires that the rates be reduced immediately following the expiration of the four-year period by the amount of the rate case expense previously included in the rates.  The reduction will reflect the removal of revenues associated with the amortization of rate case expense in the amount of $17,986, grossed-up for regulatory assessment fees to $18,834. The decreased revenues will result in the rate reduction recommended by staff on Schedule 1.

The utility should be required to file revised tariff sheets  and a proposed customer notice to reflect the Commission-approved rates.  The approved rates should be effective for service rendered on or after the stamped approval date of the revised tariff sheets pursuant to Rule 25-40.475(1), Florida Administrative Code.  The rates should not be implemented until staff has approved the proposed customer notice and the notice has been received by the customers.  The utility should provide proof of the date notice was given no less than 10 days after the date of the notice.

If the utility files this reduction in conjunction with a price index or pass-through rate adjustment, separate data shall be filed for the price index and pass-through increase or decrease, and for the reduction in the rates due to the amortized rate case expense.


Issue 8:  

Should this docket be closed?

Recommendation

 If no person whose substantial interests are affected by the proposed agency action files a protest within 21 days of the issuance of the order, this docket should be closed upon the issuance of a consummating order.   (Vining)

Staff Analysis

 If no person whose substantial interests are affected by the proposed agency action files a protest within 21 days of the issuance of the order, this docket should be closed upon the issuance of a consummating order.

DETERMINATION OF APPROPRIATE RATE STRUCTURE

 

 

 

 

 

 

 

 

 

CURRENT RATES AND HISTORY OF CURRENT RATE STRUCTURE:

 

(1)

 

The utility’s current rate structure is the traditional base facility charge (BFC) / uniform gallonage charge rate structure.  Under this usage-sensitive rate structure, customers are charged a monthly BFC of $33.06, plus $3.13 for each 1,000 gallons (kgal) used during the month.  The utility’s current rates were approved as a result of its Phase 2 filing in this case.

 

 

 

 

 

(2)

 

The most recent time the utility’s rates were adjusted as a result of a rate case was in Docket No. 940109-WU.  In that case, the utility proposed a rate design more heavily weighted towards the BFC in order to increase cash flow to cover fixed expenses during the off-season.  The Commission approved the utility’s request. (See  Order No. PSC-94-1383-FOF-WU, issued November 14, 1994, in Docket No. 940109-WU, In Re:  Petition for interim and permanent rate increase in Franklin County by St. George Island Utility Company, Ltd., p. 64.)

 

 

 

 

 

(3)

 

At the customer meetings held on September 12, 2000 during Phase One of this proceeding, several customers mentioned their preference for a rate structure with a greater emphasis placed on usage in order to reflect the different consumption habits of permanent residents versus renters.  However, because the utility’s Phase One increase in the instant docket was treated as an emergency, and because staff did not have sufficient customer usage data at that time, the Commission approved a continuation of the utility’s BFC / uniform gallonage charge rate structure, but ordered that the utility’s current rate structure be examined in Phase Three of  this case.  (See  Order No. PSC-00-2227-PAA-WU, issued November 21, 2000, in Docket No. 000694-WU, In Re:  Petition by Water Management Services, Inc. for limited proceeding to increase water rates in Franklin County, pp. 13-14.)

 

 

 

PRIOR ORDERS AND PRACTICES WITH THE WATER MANAGEMENT DISTRICTS:

 

(4)

 

The Commission has a Memorandum of Understanding (MOU) with the five Water Management Districts (WMDs or Districts).  A guideline of the five Districts is to set the base facility charges such that they recover no more than 40% of the revenues to be generated from monthly service.  (See  Order No. PSC-02-0593-FOF-WS, issued April 30, 2002, in Docket No. 010503-WU, In Re: Application for increase in water rates for Seven Springs system in Pasco County by Aloha Utilities, Inc., pp. 81-82; Order No. PSC-03-1440-FOF-WS, issued December 22, 2003, in Docket No. 020071-WS, In Re: Application for rate increase in Marion, Orange, Pasco, Pinellas and Seminole Counties by Utilities, Inc. of Florida, pp. 143-144.)  This is also a practice of the Commission.  (See  Order No. PSC-94-1452-FOF-WU, issued November 28, 1994, in Docket No. 940475-WU, In Re: Application for rate increase in Martin County by Hobe Sound Water Company, p. 12; Order No. PSC-01-0327-PAA-WU, issued January 6, 2001, in Docket No. 000295-WU, In Re: Application for increase in water rates in Highlands County by Placid Lakes Utilities, Inc., pp. 23, 28; Order No. PSC-00-2500-PAA-WS, issued December 26, 2000, in Docket No. 000327-WS, In Re: Application for staff-assisted rate case in Putnam County by Buffalo Bluff Utilities, Inc., p. 27; Order No. PSC-02-0593-FOF-WS, issued April 30, 2002, in Docket No. 010503-WU, In Re: Application for increase in water rates for Seven Springs system in Pasco County by Aloha Utilities, Inc., pp. 81-82.)

DETERMINATION OF APPROPRIATE RATE STRUCTURE  (cont.)

 

 

 

 

 

 

 

 

 

PRIOR ORDERS AND PRACTICES WITH THE WATER MANAGEMENT DISTRICTS  (cont):

(5)

 

The BFC / uniform gallonage charge rate structure had been the Commission’s rate structure of choice because it is designed to provide for the equitable sharing by the rate payers of both the fixed and variable costs of providing service.  (See  Order No. PSC-00-2227-PAA-WU, issued November 21, 2000, in Docket No. 000694-WU, In Re:  Petition by Water Management Services, Inc. for limited proceeding to increase water rates in Franklin County, pp. 13-14.)  However, over the past several years, based in large part on requests made by the WMDs, the Commission has been implementing the inclining-block rate structure as its rate structure of choice.  (See.  Order No. PSC-03-0647-PAA-WS, issued May 28, 2003, in Docket No. 020407-WS, In Re:  Application for rate increase in Polk County by Cypress Lakes Utilities, Inc., pp. 31-32; Order No. PSC-00-0248-PAA-WU, issued February 7, 2000, in Docket No. 990535-WU, In Re:  Request for approval of increase in water rates in Nassau County by Florida Public Utilities Company (Fernandina Beach System), p. 37; Order No. PSC-01-0327-PAA-WU, issued February 6, 2001, in Docket No. 000295-WU, In Re:  Application for increase in water rates in Highlands County by Placid Lakes Utilities, Inc., p. 25; Order No. PSC-02-0593-FOF-WS, issued April 30, 2002, in Docket No. 010503-WU, In Re: Application for increase in water rates for Seven Springs system in Pasco County by Aloha Utilities, Inc., pp. 81-82; Order No. PSC-03-1440-FOF-WS, issued December 22, 2003, in Docket No. 020071-WS, In Re: Application for rate increase in Marion, Orange, Pasco, Pinellas and Seminole Counties by Utilities, Inc. of Florida, pp. 143-144.)

 

 

 

 

(6)

 

Although the utility’s current rate structure is considered usage sensitive because customers are charged for all water used, the WMDs do not consider this rate structure to be a conservation-oriented rate structure.  (South Florida Water Management District, Section 2.6.1, District’s Basis for Review; Northwest Florida Water Management District, Permit No. 20040013, p. 5.)

The utility is located in the Northwest Florida Water Management District (NWFWMD) in an area of special concern.  The utility’s current Consumptive Use Permit (CUP) was issued on March 25, 2004.  Its previous CUP had expired due to the utility’s failure to timely submit a request for renewal of water use.  Additionally, WMS failed to comply with its pumping limits and a number of the specific conditions of the expired permit.  (Northwest Florida Water Management District, Staff Report to Governing Board (District Staff Report), February 13, 2004, p. 1.)

 

 

 

 

 

(8)

 

According to the above-referenced District Staff Report issued to the Governing Board before the current CUP was renewed, one of the permit conditions that WMS failed to comply with was consistently reporting its progress in implementing water conservation and efficiency measures.  (Ibid.)

WMS’s cumulative drawdown, coupled with water quality data that may indicate an increasing trend in chloride concentrations, indicate a future potential for adverse impacts from WMS’s withdrawals. (Ibid., p. 2.)  The current permit expires on April 1, 2006.  The current permit duration is two years rather than five years so that the District may closely monitor WMS’s compliance with its permit.  (Ibid.)

 

 

 

 

 

(10)

 

A specific permit condition of the utility’s current CUP is that WMS, by July 31, 2005, implement “action towards the adoption of a rate structure that promotes water efficiency and conservation (e.g., a multi-step inverted block rate structure).”  (Northwest Florida Water Management District Individual Water Use Permit No. 20040013, issued to Water Management Services, Inc. on March 25, 2004, p. 5.)

 

 

 

UTILITY’S REQUESTED PHASE THREE RATES AND RATE STRUCTURE:

 

(11)

 

The utility requested a continuation of its BFC / uniform gallonage charge.  The requested BFC was increased from $33.06 to $34.68, representing an increase of 4.9%.  The gallonage charge was increased from $3.13 to $3.28, or 4.8%.  Application of the utility’s requested BFC and gallonage charges result in 58% of the requested revenue requirement being recovered through the BFC and the remaining 42% through the gallonage charges.  (Water Management Services, Inc., Phase Three Petition, Schedule 1, p. 2)

 

 

 

THEORY BEHIND INCLINING BLOCK RATE STRUCTURES:

 

(12)

 

The goal of the inclining block rate structure is to reduce average demand.  Under this rate structure, it is anticipated that demand in the higher usage blocks will be more elastic (responsive to price) than demand in the first usage block.

 

 

 

 

 

(13)

 

There are several factors to consider when designing inclining block rates, including, but not limited to, selection of the appropriate:  a) BFC cost recovery percentage and the required conservation adjustment; b) usage blocks; and c) usage block rate factors.

 

 

 

BFC COST RECOVERY, USAGE BLOCKS AND RATE FACTORS:

 

(14)

 

Approximately 63% of the utility’s bills and 40% of the corresponding kgals are captured at 5 kgal or less.  The majority of consumption at or below 5 kgal is considered highly nondiscretionary, essential consumption.  Therefore, an important rate design goal is to minimize, to the extent possible, the price increases at 5 kgal or less.  (See  Order No. PSC-94-1452-FOF-WU, issued November 28, 1994, in Docket No. 940475-WU, In Re: Application for rate increase in Martin County by Hobe Sound Water Company, p. 12; Order No. PSC-02-0593-FOF-WS, issued April 30, 2002, in Docket No. 010503-WU, In Re: Application for increase in water rates for Seven Springs system in Pasco County by Aloha Utilities, Inc., p. 83; Order No. PSC-03-1440-FOF-WS, issued December 22, 2003, in Docket No. 020071-WS, In Re: Application for rate increase in Marion, Orange, Pasco, Pinellas and Seminole Counties by Utilities, Inc. of Florida, pp. 143-144.)

BFC COST RECOVERY, USAGE BLOCKS AND RATE FACTORS (cont.):

 

(15)

 

Based upon staff’s site evaluation of the utility’s service area, there is a great size disparity among residential customers’ homes.  There is a greater percentage of nondiscretionary consumption in smaller homes than in the much larger homes.

 

 

 

 

 

(16)

 

It is important to quantify the consumption disparity in order to appropriately target high-end users while rewarding those customers who usage is mainly nondiscretionary.  Therefore, a consumption analysis, detailing relationships between the percentage of bills and the related percentage of kgals captured at given consumption levels, is detailed in Table 4 below.

As shown in columns (b) and (c) of Table 4, approximately 80% of the utility’s bills and 59% of the corresponding kgals are captured at consumption of 10 kgal or less, 88% of the bills and 70% of the kgals are captured at consumption of 15 kgal or less, and 92% of the bills and 77% of the kgals are captured at consumption of 20 kgal or less.

 

 

 

 

(18)

 

As shown in columns (e) and (d) on Table 4, 41% of the water is used by only 20% of the bills at usage levels of 10 kgal or greater.  Similarly, 30% of the water is used by only 12% of the bills at usage levels of 15 kgal or greater.  These figures represent a consumption disparity at usage levels greater than 8 kgal.

 

 

 

 

(19)

 

Staff performed a detailed analysis of the utility’s billing data in order to select the usage blocks for evaluation of the recommended rate structure.  Based on this analysis, plus the information contained in Table 4 above, staff selected both a three-tiered and a two-tiered set of usage blocks for consideration:  The three-tiered usage blocks are for monthly usage of :  a) 0 – 8 kgal; b) 8 – 15 kgal; and c) in excess of 15 kgal.  The two-tiered usage blocks considered are for monthly usage of:  a) 0 – 10 kgal and b) in excess of 10 kgal.

Staff used comparable usage block rate factors in its analysis of the propriety of a three-tiered vs. a two-tiered inclining block rate structure for the utility, which means that the same rate factors are used to price the last block of each rate structure.  Our analysis is contained in Table 5 below.

NOTE:  Staff also tried a conservation adjustment of 44%, which resulted in a BFC cost recovery percentage of 30%.  However, this would have reduced the current BFC by approximately 50%.  Staff believes a BFC reduction of that magnitude is too great at this time.  Therefore, staff eliminated the BFC =30% option from consideration.

 

 

 

 

 

 

(21)

 

As shown in the 0 kgals column of Table 5, setting the BFC to 40% would reduce the current BFC by approximately 32%.  This represents a significant reduction in the current BFC.  Therefore, in instances in which the recommended BFC represents a significant reduction from the current BFC, staff believes that properly evaluating the utility’s ability to cover its monthly fixed costs is also important.  This analysis will be included in Attachment C of Issue 6, addressing the appropriate recommended rates for WMS.

BFC COST RECOVERY, USAGE BLOCKS AND RATE FACTORS (cont.):

 

(22)

 

As shown in Table 5 on the previous page, in the columns labeled 3 Kgals, 5 Kgals and 8 Kgals, the three-tiered inclining block rate structure with rate factors of 1.0, 1.25 and 1.5 (see Line No. 2 in Table 5) minimize the percentage price decreases at those levels of consumption.  Furthermore, this rate structure represented on Line 2 of Table 5 results in the greatest percentage price increases at 15 kgals of consumption.

 

 

 

 

 

(23)

As shown in Table 5 under the columns labeled 30 Kgals, 50 Kgals and 100 Kgals, the three-tiered rate structure with rate factors of 1.0, 1.5 and 2.5 (see Line No. 7 in Table 5) produced the greatest price signals regarding water conservation.  However, these rate factors result in price decreases up to 15 kgals of consumption, or a level approximately five times the average consumption for those customers whose monthly usage typically falls between 0 – 8 kgal.  Staff therefore eliminated the rate factors of 1.0, 1.5 and 2.0, plus those other rate structures found in Lines 3 through 6, from consideration.

 

 

 

 

(24)

As shown in Lines 8 through 13 of Table 5, the less aggressive two-tier inclining block rate structure produced neither the smallest price decreases nor the greatest price increases at any level of consumption.  Therefore, these rate structures were also eliminated from consideration.

 

 

 

 

RECOMMENDED RATE STRUCTURE:

 

Based on the foregoing, staff recommends that the three-tiered inclining block rate structure with rate factors of 1.0, 1.25 and 1.5 (see Line No. 2 of Table 5) best captures the balance between revenue stability and conservation pricing.  Furthermore, it addresses the customers’ preference for a rate structure with a greater emphasis placed on usage, and satisfies the rate structure requirement that the NWFWMD has placed on the utility.

FIXED COST RECOVERY ANALYSIS

 

 

 

 

 

 

 

 

 

(A)

Assumptions:

1.

The utility’s revenue requirement is $1,368,807.

 

 

 

 

 

 

2.

Approximately 58% of the utility’s revenues represent fixed cost recovery.  This is consistent with the fixed vs. variable cost recovery that is represented in WMS’s Phase III filing on  Schedule 1, p. 2.

 

 

 

 

 

 

3.

The utility’s fixed monthly revenue stream should be used to cover its fixed costs.

 

 

 

 

 

 

 

 

4.

The revenues generated from the minimum number of gallons sold each month represent part of the utility’s monthly fixed revenue stream.  The month in which the fewest gallons are sold by WMS occurs in February of each year.  Therefore, the number of February gallons sold represents the minimum gallons the utility can expect to sell each month, and should be included as part of the fixed cost recovery analysis.
