A transformation from coal to solar

Ontario Power Generation has recently completed a new solar facility on the site of the former largest coal-fuelled generating station in Ontario.

Explore how we're converting facilities to meet the future of Ontario's power needs.

OPG power partners

Ontario Power Generation has partnered with Six Nations Development Corporation and Mississaugas of the Credit First Nation to develop our first ever solar power facility.

Recently completed, the solar facility can generate 44 megawatts of clean, renewable power for the province — that’s enough to power a small town.

Three steps to solar power

There were three major steps involved in the expansive solar facility construction:

  1. Access roads were built for trucks and equipment to enter safely in and out of the site and fencing installed around the grounds for safety and security purposes.
  2. More than 20,000 helical piles — long, steel anchors — were screwed into the ground two metres deep and metal racking was installed onto this solid foundation.
  3. Thousands of photovoltaic panels mounted onto the racks. The panels used at Nanticoke Solar are fixed in place and don’t move to track the sun.

Electrical equipment required to connect these panels to the provincial grid — things like transformers, breakers, AC-DC inverters, and protection and control equipment — were also be installed.

Safe transport and construction

An important part of the project has involved removing equipment and buildings from the Nanticoke site to facilitate construction and prepare the site for other industrial uses.

Demolition contractor Delsan-AIM Environmental Services successfully demolished the two smoke stacks on Feb. 28, 2018.
