Home My WebLink AboutBeaver PCE Economic Analysis Summary Sheet 1990PCE ECONOMIC ANALYSIS SUMMARY SHEET Village: Beaver Analysis Date: 1/8/90 Summary: RSA estimates a fuel efficiency improvement of 1.9 Kwh/gal achieved by installing a 50 Kw gen-set in place of the existing 125 Kw gen-set. Existing generation equipment consists of a 50 Kw and 125 Kw John Deere gen-set. The 125 Kw set is blown-up. The measured connected load 10/25/88 was 39 Kw. The estimated peak connected load is ??40?? Kw. The Capital cost for the New Project Scenario assumes the 50 Kw gen-set is installed in FY90 at an estimated cost of $48,702. However, this does not include the parallel switchgear. The Capital cost for the Current Scenario assumes the 125 Kw gen-set will be replaced in-kind in FY 90 at an estimated cost of $74,000. The Maximum Construction cost based on a 10 year discounted Economic payback is $156,050. The Maximum Construction cost based on a 10 year PCE payback is $101,156. NOTE: RSA did not calculate an estimated peak connected load for Beaver. Therefore, there is a chance that one 50 Kw gen-set will not carry the full peak load.
