ESA-186-2 Public Report
The Norpac Foods Stayton plant produces frozen and canned vegetable products. The plant’s operations are seasonal; 67% of the annual energy consumption occurs during the high season months of July, August, September, and October.
Natural gas usage rates range from 9 MMBtu/h in the low season to 43 MMBtu/h in the high season. The plant purchases 100% of its electric demand. The average demand ranges from 2,000 kW in the low season to 6,300 kW in the high season.
The plant is equipped with four natural gas-fired package boilers. Process steam uses include blanchers, cookers, retorts, and heating of sanitation water.
Objective of ESA:
The objective of the Energy Savings Assessment (ESA) was to:
Focus of Assessment:
Boilers, steam distribution system, condensate return system, and process uses of steam
Approach for ESA:
The approach of the training assessment was to provide training on DOE Steam Tools suite and use them to identify and analyze potential opportunities.
General Observations of Potential Opportunities:
Annual Energy Consumption:
In 2006 the plant consumed 0.18 TBtu of natural gas and 30,105 MWh of electric energy.
Energy Savings Opportunities:
The following points should be considered when evaluating the potential opportunities identified on page 1 and described below:
1 The DOE’s Steam System Assessment Tool (SSAT) includes a number of predefined energy savings opportunities common to many, but not all, industrial steam systems. The opportunities are referred to in SSAT as Projects. Project 1 is simply a reduction in facility steam demand.
