FERC accepts rate authority for new biomass plant in Connecticut

The Federal Energy Regulatory Commission on Sept. 25 accepted a Plainfield Renewable Energy LLC application for market-based rate authority for a new, 37.5-MW biomass-fired project.

On June 20, Plainfield Renewable Energy had filed an application for market-based rate authority with an accompanying tariff. The proposed market-based rate tariff provides for the sale of energy, capacity, and ancillary services at market-based rates.

Plainfield Renewable is constructing and will own and operate a 37.5-MW biomass-fueled facility located in Plainfield, Conn. Plainfield Renewable is wholly owned by Plainfield Renewable Energy Holdings LLC.

The project will interconnect to the transmission system controlled by ISO New England (ISO-NE) at the Fry Brook Substation owned by Connecticut Light & Power (CL&P). Plainfield Energy, CL&P and ISO-NE have executed a Large Generator Interconnection Agreement for the project. The company said in the June application that it expected initial synchronization of the project in September, with commercial operation to begin in October.

The project will generate power using wood from sources including construction and demolition debris, recycled pallets, and land clearing, and will consist of a staged gasification system close-coupled with one heat recovery boiler that will generate high-pressure steam to drive one steam turbine generator. Plainfield has entered into a 15-year power purchase agreement with CL&P, under which CL&P will purchase 80% of the project’s output. PRE intends to sell the remaining 20% into the ISO-NE market.
