Impact evaluation of an energy savings plan project at ARCO Petroleum Products Company

摘要

This impact evaluation of an energy conservation measure (ECM) that was recently installed at ARCO Petroleum Products Company (ARCO) was conducted for the Bonneville Power Administration (Bonneville) as part of an evaluation of its Energy $avings Plan (E$P) Program. The Program makes acquisition payments to firms that install energy conservation measures in their industrial processes. The objective of this impact evaluation was to assess how much electrical energy is being saved at ARCO as a result of the E$P and to determine how much the savings cost Bonneville and the region. The impact of the ECM was evaluated with a combination of engineering analysis, financial analysis, interviews, and submittal reviews (ARCO's Proposal and Completion Report). The ECM itself consists of removing one stage of a six-stage compressor so that its inlet control valve can be opened wider, thereby saving the energy that was previously lost at the valve due to pressure drop. Energy savings resulting from this ECM are expected to be 2,112,800 kwh/yr. The ECM cost $367,650 to install, and ARCO received a payment of $158,460 from Bonneville and $82,902 from its serving utility, Puget Sound Power & Light Company, for the acquisition of energy savings. The ECM would not have been installed without the acquisition payment offered under the E$P Program. The levelized cost of these energy savings to Bonneville will be 6.3 mills/kWh over the ECM's expected 15-year life, and the levelized cost to the region will be 15.8 mills/kWh.
