Case Study Impact Evaluations of the Industrial Energy Savings Plan
MetadataShow full item record
This paper presents the results of a series of five case study impact evaluations of Energy Savings Plan (ESP) industrial energy efficiency projects funded by the Bonneville Power Administration (BPA) and Seattle City Light (City Light). These industrial sector evaluations are among the first in the Pacific Northwest to evaluate both energy and non-energy effects. The projects chosen for evaluation cover a wide range of industrial processes and end-uses. Each industrial setting, the efficiency measures installed and the processes affected are described in this paper. The report presents energy (kWh) and peak demand (kW) savings indexed to changes in production volume, an assessment of non-energy benefits to the participating customer, and cost-effectiveness analyses from four stakeholder perspectives. Levelized cost (expressed in cents per kWh) and benefit-cost ratios were calculated for each project, both including and excluding quantifiable energy non-energy benefits. A summary of conclusions and lessons learned is also provided. The evaluation team included Patrick Lilly of Regional Economic Research Inc., Paresh Parekh of Unicade Inc., D'Arcy Swanson of Pacific Sciences Inc., and Dennis Pearson at Seattle City Light.
