Impact evaluation of adjustable speed drives installed at Great Western Malting Company under the Energy $avings Plan

This impact evaluation of adjustable speed drives (ASDs) that were recently installed at Great Western Malting Company (GWM) was conducted for the Bonneville Power Administration (Bonneville) as part of an evaluation of its Energy $avings Plan (E$P) Program. The project consists of four ASDs that are used to control the power to motors driving kiln exhaust fans. The ASDs are being used to control the air flow rate through the compartment house malt drying kilns, which was previously controlled with dampers. The objective of this impact evaluation was to assess how much electrical energy is being saved at GWM 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 (GWM`s proposal and completion report).
