Princeton, N.J.-based power generation company NRG Energy Inc. intends to integrate biomass as a fuel source into its existing Montville Generating Station in Uncasville, Conn. The addition of biomass would fuel approximately 30 megawatts of the unit's 82-megawatt electrical generating capacity.

The company said it intends to use plant matter such as wood chips to help produce electricity. The Uncasville facility, which is currently fueled by oil and natural gas, would help reduce the facility's net carbon footprint. At press time, Biomass Magazine was unable to reach NRG Energy to ascertain a timetable for when the project would begin.

The Montville Generation Station biomass project is NRG Energy's fourth "RepoweringNRG" project in the state of Connecticut.

"Using biomass, together with fossil fuels, in our existing fleet is one of the quickest and most efficient ways to reduce carbon intensity," said Michael Liebelson, chief development officer of low carbon technology for NRG Energy. "When this biomass project comes on line, it will be another step in helping Connecticut reach its goal of creating 20 percent Class 1 renewable power generation by 2020."

This summer, NRG Energy added 40 megawatts of ultra low sulfur distillate fuel power generation at its Cos Cob site in Fairfield County, Conn., bringing the plant's total output to 100 megawatts, while reducing overall emissions from the site. Additionally, NRG Energy and The United Illuminating Co., through their GenConn partnership, are developing a combined total of 400 megawatts of new peaking generation at NRG Energy's existing sites in Middletown and Milford, Conn.

NRG Energy owns and operates 48 power plants that provide approximately 24,000 megawatts of generation capacity, which is enough to power nearly 20 million homes. NRG Energy is also a member of the U.S. Climate Action Partnership, a group of business and environmental organizations that call for mandatory legislation to reduce greenhouse gas emissions.
