Robert G. Lake Generating Station

Peterborough Utilities Inc. is pleased to announce that Trent Rapids Power Corporation (TRPC) successfully completed and placed the Robert G. Lake Generating Station into commercial operation on December 31, 2009.

The Robert G. Lake Generating Station is a new 8.0 MW run-of-the-river hydroelectric generating facility on the Otonabee River adjacent to Locks 22 and 23.  The powerhouse and southern portion of the power canal is situated within the City of Peterborough on land leased from Trent University while the intake structure and northern portion of the power canal is located within the Township of Smith-Ennismore-Lakefield. The facility operates under a water power license with Parks Canada.

The project includes the following key features:

  • Intake structure located adjacent to the west end of the Lock 23 dam;
  • A 1,050 m long power canal on the west bank of the river between the Lock 23 dam and Lock 22 dam;
  • Powerhouse containing two 4.0 MW ECOBulb turbines located about 100 m downstream of the Lock 22 dam; and
  • 44 kV substation and power line injecting energy into the local distribution grid of Peterborough Distribution Inc.

Construction of the project commenced in April 2008 and was completed in December 2009. The recently completed facility will produce and inject approximately 30,000 MWh annually into the local electrical distribution system of Peterborough Distribution Inc.

The Robert G. Lake Generating Station has a Renewable Energy Standard Offer Program (RESOP) Contract with the Ontario Power Authority (OPA) for a 40-year term. This green energy project will provide the electricity needs of approximately 3,000 homes and offset 20,000 to 30,000 tons of carbon dioxide annually.
