The Federal Energy Regulatory Commission has certified incremental generation at the 19.2-MW Mattaceunk hydroelectric project in Maine to be eligible for federal renewable energy production tax credits.
FERC certified incremental generation March 19, totaling 7,100 MWh from upgrades to Mattaceunk Units No. 2 and No. 1, completed in September and October 2005. Each unit contributed 3,550 MWh to the incremental generation figure, which represents a 6.55 percent overall increase in generation.
Mattaceunk (No. 2520), also known as Weldon Station, is located on the Penobscot River. Licensee Great Lakes Hydro America LLC converted all four of the project’s units from 40 hertz to 60 hertz and upgraded the runners. However, two of the units were upgraded in 2005 before the Aug. 8, 2005, effective date of the production tax credit.
Since passage of the Energy Policy Act of 2005, FERC has certified incremental hydropower generation at more than a dozen projects for production tax credits. (HNN 2/22/08) Incremental production gains from efficiency improvements or capacity additions to existing hydroelectric facilities must be placed in service before Jan. 1, 2009, to be eligible for the renewables production tax credit.
