The Federal Energy Regulatory Commission has certified renewable energy production tax credits to owners of six hydroelectric projects in New York and New England, including three operated by Erie Boulevard Hydropower L.P., a unit of Brookfield Renewable Power.
St. Regis River, Hudson River, Piercefield
FERC certified incremental generation at Erie Boulevard’s 6.8-MW St. Regis River (No. 10461), 83.86-MW Hudson River (No. 2482), and 2.7-MW Piercefield (No. 7387) projects, all in New York.
Erie Boulevard sought certification of incremental generation from efficiency improvements to the Allens Falls development of St. Regis, on the West Branch of the St. Regis River. (HNN 4/26/07) It replaced a turbine runner with a new runner from American Hydro, increasing both efficiency and generating capacity. FERC certified incremental generation totaling 1,604 megawatt-hours, a 4.52 percent increase.
Erie Boulevard also sought certification for efficiency improvements made to the Hudson River project’s Sherman Island development. (HNN 10/30/06) It upgraded turbines and added new turbines, increasing the total installed generating capacity of Sherman Island to 37.2 MW from 28.8 MW. FERC certified incremental generation of 19,615 MWh, a 10.94 percent increase.
Erie Boulevard sought certification of incremental generation from efficiency improvements gained by installing a new inflatable rubber flashboard system at Piercefield, on the Raquette River. FERC certified 406 MWh of incremental generation, a 2.78 percent increase.
FERC previously issued orders certifying incremental hydropower at several other Brookfield projects, including 29.08-MW Piney in Pennsylvania (HNN 11/5/08)
Gulf Island-Deer Rips
FERC certified incremental generation at the 34.4-MW Gulf Island-Deer Rips project (No. 2283), on the Androscoggin River in Maine. FPL Energy Maine Hydro LLC sought certification of incremental generation gained by upgrading Unit 2.
FPL Energy replaced the unit’s runner and rewound the generator. FERC certified incremental generation totaling 5,272 MWh, a 4.05 percent increase.
FERC certified incremental generation at the 16.8-MW Lawrence project (No. 2800), on the Merrimack River in Massachusetts.
Licensees Essex Co. and Lawrence Hydroelectric Associates increased generation by replacing wooden flashboards with an inflatable crest gate system. FERC certified incremental generation totaling 4,740 MWh, a 6.7 percent increase.
FERC certified incremental generation at 32.4-MW Vernon station (No. 1904), on the Connecticut River in New Hampshire and Vermont. (HNN 8/12/08) TransCanada Hydro Northeast Inc. sought certification of incremental generation gained from a $50 million repowering program.
TransCanada replaced four turbine-generators with higher-capacity and higher-efficiency units. FERC certified incremental generation totaling 56,401 MWh, representing a 41.64 percent increase.
