Is there a repurposed future for power plant? Economic developers speak to OPG on Decommissioned generating station.

The shuttered Thunder Bay Generating Station will likely never return to production again.

But discussions are underway between Ontario Power Generation (OPG) and the Thunder Bay Community Economic Development Commission (CEDC) to determine potential future uses of the landmark infrastructure asset, currently being decommissioned.

Doug Murray, the CEDC's chief executive officer, said they're close to signing a confidentiality agreement with OPG to start the conversation of how the properly and its buildings could be repurposed.

"Can we reposition it to do something else that's not primarily power based?"

OPG announced last July it was permanently shutting down the 56-year-old facility, citing the high cost of repairs and operations.

The 300-megawatt power plant had been a coal burner for most of its operating life until the Ontario government converted it to burn specialty wood pellets, imported from Norway.

The facility was relegated as a peaking plant in 2015.

It was sporadically fired up only during times of peak energy use, when additional power was needed on the provincial grid to meet demand.

As a power generator, the plant has outlived its usefulness.

Murray said there's already an abundance of power in the northwest, with more on way, as construction begins soon on the East-West Tie transmission project to supply new mines coming online over the next few years.

The generating station is a sprawling complex of large buildings containing hundreds of thousands of square feet of space. The station occupies 53 hectares (131 acres) on Mission Island at the mouth of the Kaministiquia River delta. The stack is 198 metres tall.

"It's a massive infrastructure piece," Murray said.

The plant is also permitted to pull and discharge a large volume of water from Lake Superior.

A concrete tunnel--used to transport coal to the plant by conveyor --connects the generating station with a marine terminal on neighbouring McKellar Island. But there are no natural gas connections to the site.

Murray wonders if the buildings, the equipment inside, and property can be repurposed for something like value-added forest products, or if the plant's boilers can be used to produce steam-generated power to attract a new industry to town.

"To market it, we need to understand what's there and what can be...
