HomeMy WebLinkAboutAtmautluak PCE Economic Analysis Summary Sheet 1990PCE ECONOMIC ANALYSIS SUMMARY SHEET village: Atmautluak Analysis Date: 1/8/90 Summary: RSA estimates a fuel efficiency improvement of 1.0 Kwh/gal achieved by installing a 75 Kw gen-set in place of the existing 230 Kw gen-set, and running the new 75 Kw gen-set in parallel with the 125 Kw gen-set for winter operation. For summer operation, RSA suggests operating the 75 Kw gen- set. Existing generation equipment consists of a 125 Kw White, 150 Kw John Deere, and a 230 Kw Cummins gen-set. The measured connected load 6/19/89 was 53 Kw. The estimated peak connected load is 154 kw. In order to meet the estimated peak load, automatic paralleling switchgear may be required. The Capital cost for the New Project Scenario assumes the 75 Kw gen-set is installed in FY90 at an estimated cost of $69,793. However, this does not include the parallel switchgear. The Capital cost for the Current Scenario assumes the 230 Kw gen-set will be replaced in-kind in FY 91 at an estimated cost of $113,971. The Maximum Construction cost based on a 10 year discounted Economic payback is $155,325. The Maximum Construction cost based on a 10 year PCE payback is $106,211.
