London Street Generating Station

Overview

London Street Generating Station has a total station output of 10 MW and is comprised of two plants; Plant 1 which is 4 MW in size and Plant 2 which is 6 MW in size.  The facility generates about 40,000 MWh of clean renewable energy annually; this is enough power to supply electricity to approximately 4,000 homes in the City.


The electricity at London Street Generating Station is produced by the flow of water in the Otonabee River, falling approximately 8 m at this site.  The electricity generated at this station is fed directly into Peterborough Distribution Inc.'s distribution system.

The facility has a Hydroelectric Contract Initiative (HCI) agreement with the Independent Electricity System Operator (IESO) for the sale of energy until the year 2030.

Plant 1

Constructed in 1884, Plant 1 is believed to be one of the first generating stations in North America. The station was originally constructed to supply power to the American Cereal Company, which became Quaker Oats and is now known as Pepsi QTG. Peterborough Utilities acquired the station from  Quaker Oats in 1975.

Plant 1 has 3 synchronous type generators which are driven by Francis type turbines. Each unit produces approximately 1.3 MW, for a total station output of approximately 4 MW.  The output from the station was used to keep the Peterborough Regional Health Centre operating during the 2003 blackout.

Plant 2

Commissioned in 2016, Plant 2 consists of two (2) 3 MW synchronous generators driven by Voith horizontal S-type Kaplan turbines, for a total station output of 6 MW. 

Key Benefits

  • Green power to 4,000 residents.
  • Plant 2 will extend the life of the existing facility.
  • Total capacity of approximately 10 MW.
  • Enhanced water level and flood control in the local area.
