Home My WebLink AboutSheldon Point PCE Economic Analysis Summary Sheet 1990PCE ECONOMIC ANALYSIS SUMMARY SHEET Village: Sheldon Poin /: Analysis Date: 4/17/90 IB Wf 9O Summary: There is the potential for $53,110 from the PCE Utilities Efficiency Improvement program to be used toward implementing the following project. The estimated project cost is $67,558. RSA estimates a fuel efficiency improvement of 1.7 kWh/gal achieved by installing a 50 Kw gen-set in place of the existing 110 kW gen-set, and running an existing 45 kW and the new 50 kW genset in parallel in the winter. Existing generation equipment consists of a 2-John Deere gen-sets (1-110 kW and 1-45 kW). The measured connected load 6/19/89 was 22 kW. The estimated peak connected load is 56 kW. The Capital cost for the New Project Scenario assumes the 45 kW genset is installed in FY90 at an estimated cost of $69,287. The Capital cost for the Current Scenario assumes the 110 kW gen-set will be replaced in-kind in FY 90 at an estimated cost of $100,055. The Maximum Construction cost based on a 10 year discounted Economic payback is $136,845. The Maximum Construction cost based on a 10 year PCE payback is $53,110.
