Impact evaluation of adjustable speed drives installed at Hewlett- Packard Company under the Energy $avings Plan
This impact evaluation of adjustable speed drives (ASDS) that were recently installed at Hewlett-Packard Company (HP) was conducted for the Bonneville Power Administration (Bonneville) as part of an evaluation of its Energy savings Plan (E$P) Program. The Program makes acquisition payments to firms that install energy conservation projects in their industrial processes. The objective of this impact evaluation was to assess how much electrical energy is being saved at HP as a result of the E$P and to determine how much the savings cost Bonneville and the region. The impact of the project was evaluated with a combination of engineering analysis, financial analysis, interviews, and submittal reviews (HP`s Proposal and Completion Report). The project consisted of installing 24 ASDs on 24 variable air volume system supply- and return-fans at HP`s Vancouver, Washington manufacturing facility. A secondary benefit to adding the ASDs was the ability to program in a night-setback feature. This feature was always present in the existing central computer system but was not used because of the lack of ASDs. Based on this impact evaluation, energy savings from this project are expected to be 2,582,900 kilowatt-hours/year (kWh/yr), or 0.30 average megawatts. The project cost $252,068 to install, and HP received payment of $201,654 (1992 dollars) from Bonneville for the acquisition of energy savings. The real levelized cost of these energy savings to Bonneville is 7.0 mills/kwh (in 1992 dollars) over the project`s assumed 15-year life, and the real levelized cost to the region is 10.8 mills/kwh in 1992 dollars, not including transmission and distribution effects. This project would not have been implemented without the acquisition payment from Bonneville.
