Impact evaluation of a refrigeration control system installed at Columbia Colstor

PDF Version Also Available for Download.

Description

This impact evaluation of a computer-based refrigeration control system (RCS) installed at Columbia Colstor in 1990 was conducted for the Bonneville Power Administration (Bonneville) by Pacific Northwest Laboratory (PNL). Concurrent with installing the RCS, the plant was expanded by adding 13,900 m{sup 2} (150,000 ft{sup 2} of storage space and five freeze tunnels. Because this project involved a significant plant expansion, it was ineligible for participation in Bonneville`s Energy $avings Plan Program (E$P). Therefore, a special contract was negotiated. This contract followed, to the extent possible, the E$P principles, adminstrative procedures, and acquisition payment. The primary objectives of this impact ... continued below

Description

This impact evaluation of a computer-based refrigeration control system (RCS) installed at Columbia Colstor in 1990 was conducted for the Bonneville Power Administration (Bonneville) by Pacific Northwest Laboratory (PNL). Concurrent with installing the RCS, the plant was expanded by adding 13,900 m{sup 2} (150,000 ft{sup 2} of storage space and five freeze tunnels. Because this project involved a significant plant expansion, it was ineligible for participation in Bonneville`s Energy $avings Plan Program (E$P). Therefore, a special contract was negotiated. This contract followed, to the extent possible, the E$P principles, adminstrative procedures, and acquisition payment. The primary objectives of this impact evaluation were to assess how much electrical energy is being saved at Columbia Colstor as a result of the Bonneville`s acquisition payment 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, billing analysis, financial analysis, interviews, and submittal reviews. Based on this impact evaluation, energy savings from this project are expected to be at least 4,130,700 kilowatt-hours/year (kWh/yr), or 0.47 average megawatts (aMW). Because the refrigeration system at Columbia Colstor provides cooling to both the storage rooms and the freeze tunnels, it i not possible to state savings on a per-ton basis. The project cost $287,528 to install, and Columbia Colstor received payment of $180,375 (1991 dollars) from Bonneville for the acquisition of energy savings. The real levelized cost of these energy savings to Bonneville is 4.5 mills/kWh (in 1993 dollars) over the project`s assumed 15-year life, and the real levelized cost to the region is 7.6 mills/kWh in 1993 dollars, not including transmission and distribution effects.
