HomeMy WebLinkAboutEligibility of AVEC Utilities for PCE Efficiency Improvement Program Funds 1990MEMORANDUM STATE OF ALASKA ALASKA ENERGY AUTHORITY To: Dave Denig-Chakroff Date: 5/7/90 Director of Rural Programs Thru: Dick Emerman ) 4 Senior Economist Zz From: Steve Stassel Engineering Analyst Subject: Eligibility of AVEC Utilities for PCE Efficiency Improvement Program Funds Attached is the PCE analysis for Shungnak, an AVEC utility. AVEC has proposed an upgrade that would, according to their analysis, improve efficiency by 1.0 kWh/gallon at a construction cost of $110,000. Unless State funds are provided, AVEC is expected to finance the project with a loan either from REA, a private bank, or (funds permitting) the Power Project Loan Fund. The key assumption for this analysis is that the project will be completed regardless of the availability of PCE Efficiency Improvement funds. Our conclusions are as follows: 1) An economic analysis is not applicable since it is assumed the project will be completed at the same cost, and with the same improvements in fuel efficiency and reduced O&M costs, regardless of the availability of PCE Efficiency funds. The same amount of resources will be expended with the same effect in either scenario. 2) The financial (or PCE rate) analysis indicates that the project will prevent an annual increase to the PCE program of $7,663/year, if the $110,000 project cost is not claimed as an eligible non-fuel cost in the PCE rate tariff (i.e., the project is funded through a grant.) Using the 10-year simple payback criteria, this could justify a PCE Efficiency grant amounting to $76,630, or 70% of the project cost. 3) Based on a nominal interest rate of 7%, an inflation rate of 4.5%, a real interest rate of 2.39%, and a 10 year amortization schedule, an argument could be made that ALL AVEC utility projects could be eligible for funding through the PCE Efficiency Improvement Program for roughly 70% of the estimated project cost. (This is based entirely on AVEC’s avoided increase in non-fuel costs as a result of receiving grant funds as opposed to financing debt service, and not on improvements in efficiency.) A similar case can be made for utilities such as THREA, Alaska Power & Telephone Co., Nome, and Kotzebue, etc., if we assume they too will borrow or invest their own money in efficiency and O&M improvements that will provide identical costs and savings as would be realized if the Energy Authority performed the work. This raises the following basic questions: Should PCE Efficiency funds be reserved only for improvements that, in our opinion, would not otherwise occur; or should they also be used to share the cost of improvements that would be made anyway? Arguments supporting the first position are: 1) PCE Efficiency grant funds are limited. The program purpose is not served if the grants produce no greater efficiency in rural systems than would otherwise occur. 2) Assuming survival of the PCE program, the State will share the cost of utility- financed efficiency projects in any event. In the case of Shungnak, the alternatives presently facing the State are: a) Share the project cost with an initial grant of $76,630 from limited PCE Efficiency funds plus 70% of the balance shared through future PCE payments; or b) Share the project cost over an assumed 10-year period with annual PCE payment of $7,663. Looking at it this way, the State shares a substantial portion of the cost of the Shungnak project in either case. However, by using annual PCE funds to share efficiency project costs where possible and reserving PCE Efficiency grants for those projects that would not otherwise be financed, more cost-sharing of efficiency projects can be accomplished. The argument supporting the second position is basically that it appears unfair to deny PCE Efficiency funds to the utilities that are active enough to develop their own efficiency projects and sources of financing. As a result, program benefits are reserved exclusively for the less capable utilities. ce: Brent Petrie Gary Smith SHUNGNAK.XLS,5/7/90, PCE ECONOMIC ANALYSIS Village: Shungnak Construction Cost: $110,000 Elec.
