Robert G. Lake Generating Station

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;
  • Power house 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 Robert G. Lake Generating Station commenced in April 2008 and was completed in December 2009. The facility is owned by Trent Rapids Power Corporation (TRPC), a wholly owned subsidiary of Peterborough Utilities Inc.

TRPC has a Renewable Energy Standard Offer Program (RESOP) Contract with the Ontario Power Authority (OPA) for a 40-year term. This green energy project produces approximately 30,000 MWh annually and provides the electricity needs of approximately 3,000 homes.
