HomeMy WebLinkAboutAkiachak PCE Economic Analysis Summary Sheet 1990PCE ECONOMIC ANALYSIS SUMMARY SHEET Village: Akiachak Analysis Date: 1/8/90 Summary: RSA estimates a fuel efficiency improvement of 1.4 Kwh/gal achieved by installing a 150 Kw gen-set in place of the existing 300 Kw gen-set, and running 2-150 Kw machines in parallel. Existing generation equipment consists of 2-Deutz gen-sets (1-150 Kw and 1-100 Kw) and a 300 Kw CAT gen-set. The measured connected load 6/19/89 was 76 Kw. The estimated peak connected load is 200 Kw. In order to meet the estimated peak load, automatic paralleling switchgear is required. The Capital cost for the New Project Scenario assumes the 150 Kw gen-set is installed in FY90 at an estimated cost of $86,132. However, this does not include the required parallel switchgear. The Capital cost for the Current Scenario assumes the 300 Kw gen-set will be replaced in-kind in FY 91 at an estimated cost of $115,053. The Maximum Construction cost based on a 10 year discounted Economic payback is $109,192. The Maximum Construction cost based on a 10 year PCE payback is $133,547. Village: Akiachak Elec.
