SAULT STE. MARIE (August 2, 2018) – Algoma announced today that just four months after its
acquisition of its neighbouring combined heat and power plant (formerly Lake Superior Power
Plant), the idled facility is back online supplying power to Algoma’s power grid. August 1st, 2018
marked its first day of production, generating 32 MW of power just in time to meet summer’s peak
power requirements.

Algoma CEO Kalyan Ghosh commented on the development, “The redundancy this facility will
provide as several of our existing assets approach end of life is of critical importance. Not only
does it give Algoma the capability to satisfy its peak power requirements, but it significantly
enhances our reliability as we look to ramp up plate production to meet domestic demand.”

The combined heat and power plant has capacity to increase output to 110MW with the addition of
a second gas turbine. Initially, the facility will operate intermittently, supplementing Algoma’s
current supply of power and steam for the steelworks operation.
