HR Milner Generating Station
The Milner 2 (“M2”) power plant is a 204 MW state-of-the-art natural gas-fired turbine generator located at the HR Milner Generating Station site near Grande Cache, Alberta. The M2 unit was commissioned in Q2 2020 and is the largest simple cycle natural gas-fired power plant in Alberta.
Having previously procured the HRSG, the M2 unit is currently being converted to a Combined Cycle Gas Turbine (“CCGT”) unit which will increase the capacity to 300 MW and lower its operating costs significantly. The M2 CCGT will benefit from significant existing infrastructure at the brownfield site, including an existing steam turbine generator and the associated balance of plant.
The original HR Milner Generating Station (“Milner 1” or “M1”), located near Grande Cache, Alberta, is a 150 MW dual fuel steam turbine generator capable of burning both natural gas and coal.
Milner 1 will be repowered during 2021/22 as part of the M2 CCGT expansion project. The steam generated by waste heat and supplementary gas-firing from M2 will be sent to M1 to generate approximately 96 MW of incremental low-carbon power.
Power produced from M2 and M1 is sold to the Alberta Electric System Operator (“AESO”).
