Public Recognition
Past Winners

Bridgewater Correctional Complex Cogeneration Plant
(Awarded ENERGY STAR CHP Award October 1, 2009, at 2009 CHP Partners Meeting)

The Bridgewater Correctional complex consists of 785,000 square feet of living and working space on 14,900 acres. In 2006, the Commonwealth of Massachusetts Department of Correction began operating a 1,500 kW CHP system to support those facilities and an inmate population of over 2000 people.

The CHP system utilizes a Kawasaki natural gas-fired combustion turbine to generate nearly 80 percent of the complex's annual electricity demand. Equipped with Kawasaki XONON combustors, the NOX emissions from the turbine are low enough to meet NOX emission requirements without the need for add-on pollution controls.

Otherwise wasted heat is recovered from the turbine exhaust and used to produce steam to support the daily heating, cooking, cleaning, and domestic hot water needs of the complex. Operation of the CHP system also allowed the Department of Correction to shut down an old and more-polluting diesel engine generator.

With an operating efficiency of approximately 67 percent, the CHP system requires approximately 17 percent less fuel than typical onsite thermal generation and purchased electricity. Based on this comparison, the CHP system effectively reduces CO2 emissions by an estimated 3,600 tons per year. This reduction is equivalent to the annual emissions from 600 passenger vehicles.

EPA is proud to recognize the outstanding pollution reduction and energy efficiency qualities of this project by presenting the Commonwealth of Massachusetts Department of Correction with a 2009 ENERGY STAR CHP Award.

Carville Energy Center

Patterson Farms CHP System
(Awarded ENERGY STAR CHP Award October 1, 2009, at 2009 CHP Partners Meeting)

Patterson Farms, a sixth generation family-owned and operated business since 1830, has 1,000 dairy cows and young stock on 2,400 acres in Auburn near Cayuga Lake in upstate New York. In 2005, a first CHP system was installed to generate electricity and heat for the farm while addressing an odor problem that had arisen from the use of an on-site manure lagoon.

This CHP system generates up to 200 kW of electricity from the combustion of biogas in a Caterpillar internal combustion engine. The biogas is produced from an anaerobic digester that processes nearly 50,000 gallons per day of manure waste from the dairy cows and 15,000 gallons per day of food waste from a cream cheese production facility. Hot water produced by capturing the otherwise wasted heat from the engine block is used to maintain the digester temperature. Excess power generated by the CHP system is sold to the local utility grid due to the state's net metering provisions.

With an operating efficiency of approximately 58 percent, the CHP system requires approximately 6 percent less fuel than typical onsite thermal generation and purchased electricity. Based on this comparison, the CHP system effectively reduces CO2 emissions by an estimated 340 tons per year. This reduction is equivalent to the annual emissions from 57 passenger vehicles.

EPA is proud to recognize the outstanding pollution reduction and energy efficiency qualities of this project by presenting the Patterson Farms with a 2009 ENERGY STAR CHP Award.

717 5th Avenue Cogeneration Plant
(Awarded ENERGY STAR CHP Award October 1, 2009, at 2009 CHP Partners Meeting)

Located in the Plaza District of New York City, the 717 5th Avenue building contains 450,000 square feet of Class-A office space owned and leased by Equity Office Properties. More than 60 percent of the building's electrical and thermal demands are met using 1.6 MW CHP system centered on a Caterpillar internal combustion engine. Supported by a grant from NYSERDA and operated by Endurant Energy, the natural gas-fired CHP system is the first of its kind to be synchronously interconnected to the midtown utility grid.

With an operating efficiency of approximately 77 percent, the CHP system requires approximately 33 percent less fuel than typical onsite thermal generation and purchased electricity. Based on this comparison, the CHP system effectively reduces CO2 emissions by an estimated 1,200 tons per year. This reduction is equivalent to the annual emissions from 204 passenger vehicles.

Consolidated Edison East River Repowering Project
(Awarded ENERGY STAR CHP Award June 29, 2009, at the Annual IDEA Conference)

Powered by two natural gas-fired combustion turbine generators and innovatively constructed within an existing structure, Consolidated Edison's East River Generating Station in New York City, New York is a CHP system that produces 360 MW of electricity and 3.2 million pounds of steam per hour. Con Edison operates the largest district steam system in the country. The system is a key component of the infrastructure of New York City. The steam generated helps to displace peak electricity demand on the grid in Manhattan. District steam, which is produced using otherwise wasted heat from the turbine exhaust, is supplied through 105 miles of underground piping to support both the daily steam heating and cooling needs of approximately 1,800 buildings in New York City. With an operating efficiency of nearly 80 percent, the CHP system requires approximately 34 percent less fuel than typical onsite thermal generation and purchased electricity. The CHP system effectively reduces CO2 emissions by an estimated 900,000 tons per year. This reduction is equivalent to 185,000 acres of pine or fir forests storing carbon for one year or the annual emissions from 150,000 passenger vehicles.
