This impact evaluation of two lighting retrofit projects that were recently installed at Boeing Commercial Airplane Group (Boeing) was conducted for the Bonneville Power Administration (Bonneville) as part of an evaluation of its Energy $avings Plan (E$P) Program. The first project was a light-fixture and lighting control retrofit, consisting of five individual measures installed in Building 40-05. The second project was a retrofit of all parking lot lighting on the site. The objective of this impact evaluation was to assess how much electrical energy is being saved at Boeing as a result of the E$P projects 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 (Boeing`s proposals and completion reports).

Over the past 10 years, the Pacific Northwest has gone from a region with excess electricity generating capacity to one facing dramatic short-ages. Faced with potential deficits, the region's largest power producer, the Bonneville Power Administration (Bonneville), has embarked on an aggressive industrial energy conservation and savings evaluation program. Bonneville's Energy $avings Plan (E$P) Program targets industrial customers by offering acquisition payments for approved industrial energy conservation projects. Since the program's inception in 1987, 52 E$P projects have been completed for a combined annual savings of more than 98 million kilowatt-hours per year, or 11.2 average megawatts. To date, the 52 participants have received acquisition payments totaling $3,441,000 on projects with a total installed cost of $37,495,000.
