Open Doors Peterborough to Include London Street Generation Station

Peterborough Utilities Opens Newly Renovated London Street GS to the Public


(April 30, 2018, Peterborough, ON) The Ontario Waterpower Association (OWA) is happy to announce that Peterborough Utilities Inc. (PUI) will be hosting public tours of its newly expanded and renovated London Street Generating station, as part of Peterborough Door’s Open event.  Tours of this facility are free and will take place on May 5th, 2018 from 10am – 4pm.

Abundant and inexpensive hydroelectricity was one of the primary reasons the American Cereal Company, later to become Quaker Oats and currently PepsiCo QTG, located to the city in 1902 and remains a major fixture in the downtown area to this day. It was also a motivating factor in Peterborough Utilities Inc.’s decision to invest approximately $35 million in the expansion and life extension of the London Street Generating Station.

“Featuring waterpower in the Doors Open Ontario campaign is a natural fit,” said Paul Norris, President of the OWA. “Many Ontario communities were built around waterways and waterpower was the first source of renewable electricity. These events provide the public with a unique opportunity to have a sneak a peek inside some historic gems and some brand new projects.”

Engineering was provided by Hatch and an early contractor engagement approach to contracting was adopted to leverage the experience and capabilities of the general contractor. Voith Hydro was selected as the turbine-generator vendor.  Two horizontal ‘S’ type Kaplan turbine units couple to direct drive synchronous generators were chosen for the project to optimize production from the new plant over a wide range of flow and head conditions.

The new 6 MW London Street GS expansion project (Plant #2) achieved commercial operation on July 29th 2016 and interior restoration of the original 4 MW Plant #1 has recently been completed.  The combined 10 MW capacity of the two plants allowed the facilities to generate in excess of 57,000 MWh of renewable energy in 2017, enough electrical power to supply the needs of approximately 5,700 homes in Peterborough.

PUI’s Manager of Generation Operations, Jason Hoskin, has been part of the growth of PUI’s generation assets over the past several years.  “It’s been very rewarding and challenging to be part of this growth.  The contrast between century old equipment with manual operating systems and the new equipment with PLC based operating systems and interfaces is dramatic.”

The Ontario Waterpower Association (OWA) was founded in 2001 to represent the common and collective interests of the province’s original renewable energy sector – waterpower.
