Capital Power and TransAlta Corporation have completed the 495MW Keephills 3 generating facility in Alberta, Canada, and the plant has commenced commercial operations.

The companies jointly own this coal-fired power plant, and Capital Power led the construction of the facility which will be operated by TransAlta.

Both companies equally shared the costs for the power plant, excluding mine capital.

The facility is equipped with an advanced air quality control system, which uses supercritical boiler technology that features higher boiler temperatures and pressures, and a high-efficiency steam turbine.

Keephills 3 also includes a mercury emission control system, using activated carbon injection technology, and a high-efficiency particulate collection system, using fabric filters (baghouse) to capture 99.9% of particulate emissions, the companies said.
