Covanta Bristol plant to sell output on ISO New England market

Due to the imminent end of a power supply contract, Northeast Utilities Service Co. (NUSCO), on behalf of affiliate The Connecticut Light and Power Co. (CL&P), submitted to the Federal Energy Regulatory Commission on June 30 a Generator Interconnection Agreement between CL&P and Covanta Bristol Inc.

Covanta’s facility is an approximately 16.3-MW steam turbine generator located in Bristol, Conn. It is a qualifying facility (QF) under the Public Utility Regulatory Policies Act of 1978.

The facility has been in operation since 1988 and is interconnected to the distribution system of CL&P. CL&P has been purchasing power from it under an Electricity Purchase Agreement (EPA) dated August 1985. The EPA included provisions under which CL&P provided interconnection service to the Generating facility. By agreement between CL&P and Covanta, the EPA expires on June 30, 2014.

“The Generating Facility has been connected to CL&P distribution system since 1988, and CL&P has, in turn, been purchasing the power under the EPA and selling theoutput from the Generating Facility into the ISO-NE market through the New England transmission system,” NUSCO told the commission. “Going forward, Covanta will continue to make use of CL&P’s distribution system and the New England transmission system to market the output of the Generating Facility. Covanta intends to sell the electric power output from the Generating Facility into markets administered by ISO-NE in accordance with the ISO-NE Tariff. CL&P and Covanta executed the Interconnection Agreement to provide the rates, terms and conditions for continued interconnection service for the Generating Facility.”

The Covanta facility has already been participating in the ISO-NE market,and Covanta is not modifying the existing power facility or the interconnection facilities. The power plant consists of two municipal waste combustor units, each having a design capacity of approximately 358 tons per day of municipal solid waste, assuming a higher heating value of 4,500 Btu per pound. Heat is recovered from the combustion process in the form of steam. There is one General Electric turbine generator with a nameplate capacity of 16.3 MW. Power is generated at 13.8 kV and delivered to CL&P’s Forestville Substation.
