 Case Background

On June 15, 2007, Tampa Electric Company (TECO) filed a petition requesting approval of modifications to the company's existing demand side management (DSM) plan, as well as authorization to recover the associated reasonable expenses through the Energy Conservation Cost Recovery Clause (ECCR).  The current plan was approved by Order No. PSC-05-0181-PAA-EG, issued February 16, 2005, in Docket No. 040033-EG, In re: Petition for approval of numeric conservation goals by Tampa Electric Company

TECO alleges that the most recent annual review of conservation programs gave clear indication that increased program participation and additional savings could be achieved in both the residential and commercial sectors.  As a result, TECO proposes twelve new programs and nine program modifications.

This recommendation addresses the program modifications and additions, as described in the petition.  The Commission has jurisdiction over this matter pursuant to sections 366.06, 366.80 through 366.82, Florida Statutes.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Discussion of Issues

Issue 1

 Should the Commission approve Tampa Electric Company's (TECO) petition to modify nine of the company's DSM programs and add 12 new programs as described in its petition?

Recommendation

 The Commission should approve all the modifications and programs, except the Commercial Demand Response program, as set forth in TECO's petition.  The Commission should, however, grant limited authorization for TECO to implement the Commercial Demand Response program for a maximum period of four years.  All the programs are each monitorable and cost-effective.  TECO should be allowed to request recovery of reasonable costs associated with the approved modifications and new programs through the Energy Conservation Cost Recovery (ECCR) clause.  TECO should provide updated cost-effectiveness analysis for the Commercial Demand Response program as part of its annual filings in the ECCR proceeding.  If the Commercial Demand Response program is modified during the contract period, or at the close of the current contract, the program would also be subject to Commission approval. (Sickel)

Staff Analysis

 In the recently completed annual evaluation of the approved demand side management (DSM) plan, TECO found indications that (1) certain DSM programs could be modified in such a manner as to increase the potential of customer participation, and (2) new DSM programs for residential and commercial sectors could be developed.  The company states that recent cost evaluations, based on higher costs for both fuel and avoided units, result in cost-effective new and modified DSM programs.

TECO proposes modifications to four residential programs and five commercial programs.  In addition, new residential programs include an educational pilot program directed at eighth grade students and their families, a new residential audit program, a low income program and a residential building envelope program.  Eight new commercial programs are proposed.  Attachment A provides a brief explanation of each new or modified program, along with tables illustrating the projected demand and energy savings that each plan will contribute toward TECO's numeric conservation goals.  The programs have been evaluated using the following criteria:               

·        Whether the program advances the policy objectives of Rule 25-17.001, Florida Administrative Code, and Sections 366.80 through 366.85, Florida Statutes, also known as the "Florida Energy Efficiency and Conservation Act" (FEECA);

·        Whether the program is directly monitorable and yields measurable results; and

·        Whether the program is cost-effective 

Each of the proposed programs is designed to meet the conservation goals prescribed by the Commission and the policy objectives of Rule 25-17.001, Florida Administrative Code, and FEECA.  TECO's methodology for evaluating demand and energy savings continues as it has been under the currently approved goals.  The modified and new programs are cost effective under the Rate Impact Measure (RIM), Total Resource Cost (TRC), and Participants tests.  The actual expenditures will be reviewed within the annual Energy Conservation Cost Recovery docket.

Commercial Demand Response Program:  The Commercial Demand Response program differs in several ways from any program previously approved for a regulated energy provider in Florida.  Implementation of the program requires two contracts involving a third party demand response vendor.  First, commercial customers having equipment that can be utilized in a demand reduction program are to be identified by the vendor.  By agreement with the customer, the vendor will then install automated controls and provide load tracking software for the customer's use.  The vendor also enters into a contract with TECO that specifies payment based on a specific demand reduction.  In turn, the vendor makes ongoing payments directly to the customer, based on the contract between those two parties.

Staff is advised that the contract between TECO and the vendor has been finalized and that the contract has been submitted, with intent to request confidential treatment, for review by staff.  TECO represents that the contract period extends four years from the date of signing.  Other contract arrangements include payment by TECO to the vendor based on performance, that is in $ per kW of available demand curtailment that is contractually arranged.  There is a penalty clause, so that if the vendor fails to achieve the projected demand savings, the penalty paid to TECO is 150% of the amount TECO would have paid for demand avoided.  Vendor performance is further secured by letter of credit. 

The participating customers can expect savings on their utility bills, as well as payments directly from the third party vendor.  By implementing the proposed program, TECO will be able to reduce peak demand when needed, for both summer and winter seasons.  TECO reports that similar programs are known to be successful in other states, and that some of the utility's customers have requested this type of program because of experience in other states.  

TECO has provided projections of costs and benefits that are expected from the program. TECO represents that projections include the payment amounts as set forth in the contract.  Staff notes that the projections go beyond the four year duration of the new contract, and reflect TECO's expectation that the program and participation will grow throughout the 2007-2014 period.  The projections result in a benefit/cost ratio for the Total Resource Cost (TRC) test of 1.31, and a Rate Impact (RIM) value of 1.31.

TECO represents that the Demand Response program is an opportunity for cost-effective conservation that will be well received by customers.  Based on the projections provided by TECO, the Demand Response Program offers an opportunity for demand savings greater than any other program offered.  There are savings in energy consumption as well.  TECO represents that no payment is made to the vendor prior to the savings that the program makes available.  Should the vendor not deliver the promised savings, the penalty payments will be an offset to conservation costs for which recovery is sought. 

The next regular review of conservation goals and programs for TECO would take place in 2009.  The actual results of the program for more than four quarters will be available within the scope of that review.  Staff recommends that TECO be authorized to implement the program as proposed, subject to a thorough review of costs, benefits, and conservation actually achieved when the goals are next set.  During the interim period, reasonable costs associated with the Demand Response program are appropriate for cost recovery through the ECCR clause.  TECO should provide updated cost-effectiveness analysis as part of the annual filings in the ECCR proceeding.  Within the anticipated review in 2009, the Demand Response program would be subject to action by the Commission based on actual results.  If the program is modified during the contract period, or at the close of the current contract, the program would also be subject to Commission approval. 

            Conclusion: The Commission should approve all the modifications and programs, except the Commercial Demand Response program, as set forth in TECO's petition.  The Commission should, however, grant limited authorization for TECO to implement the Commercial Demand Response program for a maximum period of four years.  All the programs are each monitorable and cost-effective.  TECO should be allowed to request recovery of costs associated with the approved modifications and new programs through the Energy Conservation Cost Recovery (ECCR) clause.  TECO should provide updated cost-effectiveness analysis for the Commercial Demand Response program as part of its annual filings in the ECCR proceeding.  If the Commercial Demand Response program is modified during the contract period, or at the close of the current contract, the program would also be subject to Commission approval.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Issue 2

 Should TECO be authorized to make the Prime Time load control program available to new occupants of a residence which has the necessary equipment previously installed?

Recommendation

 No. The requested continuation of the Prime Time program has not been shown to be cost effective at the present time.  If an updated analysis of a proposed modification to the program indicates that modification is cost-effective, TECO may petition to include the modified program in its conservation offerings. (Sickel)

Staff Analysis

 The Prime Time program is a residential load control program that has been utilized since the early 1980's.  The program had been cost-effective until the most recent Commission review of conservation goals in 2005.  At that time, the Prime Time program was deemed to not be cost effective based on a benefit-cost ratio of 0.74 under the Rate Impact Measure (RIM) test.  See Order No. PSC-05-0181-PAA-EG, issued February 16, 2005, in Docket No. 040033-EG, In re: Petition for approval of numeric conservation goals by Tampa Electric Company, which states in part:

            Because the Prime Time load management program is no longer cost     effective, non-participating customers will continue to pay a            subsidy to program participants if the program is allowed to             continue.  For this reason we find that TECO shall close the       program to new participants, but allow current participants to      continue on the program.  Discontinuing the Prime Time program for new             customers will allow attrition to occur more rapidly, resulting in less of a             subsidy paid by non-participants.

TECO reports a net loss of 14,708 participants from February, 2005, through April, 2007.  For that period, the projected loss had been less than 3,300 customers.  The company had expected to maintain the demand reduction that has been associated with the Prime Time program through growth of the new Price Responsive Load Management program.  The attenuation of the number of participants in Prime Time program has been greater than anticipated and TECO seeks to curtail the loss of Prime Time participants.

TECO does not offer a current cost-effectiveness analysis of the requested program continuation.  In support of their request, the company states that the existing load-management equipment and its annual maintenance were deemed cost-effective at the time the equipment was installed in a residence.  Based upon that history, TECO seeks to retain a residence in the program if active equipment exists at the residence, by a transfer of the program to a new occupant.  The support offered for TECO's request does not address the finding in Order No. PSC-05-0181-PAA-EG quoted above, that non-participating customers are providing a subsidy to participants of the program.  

Staff recommends that TECO only should be authorized to allow continued participation by current customers in the Prime Time program, but TECO should not be allowed to transfer the program to a new occupant.  TECO should not to apply the demand and energy savings impacts of the prime Time program towards its Commission-authorized numeric conservation goals.  Staff notes that customers desiring to participate in a load control program have access to the Price Responsive Load Management program, recently approved in Docket No. 070056-EI, In re: Petition for extension and permanent status of price responsive load management pilot program, by Tampa Electric Company.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Issue 3

 Should the Commission approve TECO's request to modify its currently approved conservation goals?

Recommendation

 If issues 1 and 2 are approved, then the Commission should approve TECO's request to modify its currently approved conservation goals.  The proposed modifications and additions to the conservation programs will result in additional savings to both residential and commercial peak loads, as well as reduced energy consumption. (Sickel)

Staff Analysis:  If the Commission approves the proposed modifications to existing programs, and the new programs proposed for addition, the change will result in greater reductions to peak demand for TECO's system.  There will be a reduction to the energy requirements for the system as well.  The proposed increased savings for residential programs and the proposed increased savings for commercial/industrial programs are shown in the respective tables in Attachment A.  Since the savings for the currently approved programs were projected for the period 2005 through 2014, the same period is used for analysis in this docket. The projected results of the new programs over the period 2007-2014 are added to the actual conservation achieved for years 2005 and 2006.  The tables in Attachment A show accumulated savings for the proposed programs.  The table below provides a comparison of savings for the proposed programs, added to existing approved programs not changed, and compared to the current approved goals.

Issue 4

 Should the proposed modifications to the Tariff Sheets 3.150 and 3.200 be approved?

Recommendation

 Yes.  If Issue 1 is approved, the proposed tariff sheets implement the increased load management credits discussed in this recommendation. (Kummer)

Staff Analysis

 The proposed tariff sheets reflect the increased credit associated with commercial programs involving stand-by generators and the load management rider.  The programs are included in the discussion in Issue 1 and should be approved.  The tariffs should be effective the date of the consummating order.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Issue 5: Should this docket be closed?

Recommendation:  Yes.  If Issue 1 is approved, the tariffs and programs should become effective on the date of the consummating order

.  If no timely protest is filed, this docket should be closed upon the issuance of a consummating order. (Fleming)

Staff Analysis:  If Issue 1 is approved, the tariffs and programs should become effective on the date of the consummating order.

  If no timely protest is filed, this docket should be closed upon the issuance of a consummating order.
