Greenville
Location: ME
Operator: New Energy Capital Corp
Configuration: 1 X 16 MW
Operation: 1985
Fuel: wood
Boiler supplier: EPI
T/G supplier: ??
EPC: Stone & Webster, Pizzagalli Construction
Quick Facts: The plant was acquired from Hafslund ASA in Sep 2005.  Originally, the plant burned sawmill residues and waste wood in a B&W vibrating stoker boiler.  More recently, carpet remnants were added to the fuel mix. The plant was refit for wood-firing only with a BFB boiler from EPI and new back-end emissions control equipment from Mobotec. This and other upgrades completed for $6.9mn will qualify the facility as a New Renewable Generating Unit under Massachusetts regulations, making it eligible to sell Renewable Energy Certificates (RECs) to load-serving entities in the New England market.
