Research Project Summary Information
Allied Frozen Storage Combined Cycle Power Generation(ST7855A-1)
Allied Frozen Storage, Inc.
Most modern frozen food storage and processing facilities employ electric cooling equipment as the means to provide the required climatic conditions, where temperatures below zero degrees Fahrenheit are commonly required. Electricity cost is the largest component of operating cost, and reliable electric supply is critical.
The host site for this project, Allied Frozen Storage, Inc., of Brockport, New York, is representative of frozen food storage facilities found throughout New York State. The site consists of a cluster of three storage facilities owned by Allied Frozen Storage, Inc., and one processing facility owned by one of its customers, Birdseye Foods. Together, these four facilities employ 345 people and provide over 14 million cubic feet of frozen storage area.
Through this project, Allied Frozen Storage, Inc. has installed and demonstrated the efficiency of a combined heat and power (CHP) system at its site in Brockport, New York, which provides electric power, process refrigeration, and space heating from a single combustion system, thereby reducing the cost of electric bills, conserving energy, and reducing air pollution. The CHP System is grid-connected in the electric service territory of National Grid, and also has emergency backup generation capability that enables the facility to generate electric power if a grid power failure occurs.
This project has installed 2,500 kW of new CHP and 1,250 kW of new emergency backup generation. A new absorption chiller has been installed to convert the exhaust heat into refrigeration as a replacement of the existing 150 kW electrically-driven chillers. The project will evaluate two operating scenarios, one of which will ultimately be selected:
1) CHP will be operated 24 hours per day and 365 days per year except during periods of scheduled maintenance or malfunctions; or
2) CHP will be operated during peak times (daytime during weekdays) and shut down at off-peak times (entire weekend, and nights during weekdays).
Technology transfer and publicity have emphasized wide dissemination of the project results. This project is forecast to provide peak load reduction of approximately 2,500 kW, and operate at energy efficiencies that exceed 65 percent year round.
The CHP system began operation in late 2008. The system is producing electricity, but problems with the heat recovery system are still being addressed. Once project economics and technology application have been proven, there will be opportunities to replicate this technology at other facilities owned by Allied Frozen Storage, Inc., in Buffalo and West Seneca, New York, and at frozen food storage facilities owned by others elsewhere.
