The Alberta Utilities Commission on June 26 approved an application from Aquatera Utilities Inc. for approval to construct and operate a 2.85-MW power plant at its water and wastewater treatment plant, located in the city of Grande Prairie.
The bioreactor landfill gas-to-energy project would consist of two 1.425-MW GE Jenbacher JMS 420 dual fuel (landfill gas/natural gas) generators. The generators would be capable of operating by themselves, in parallel, or in cogeneration with the power grid.
Aquatera stated that the primary fuel supply for the power plant would be landfill gas collected and transmitted by pipeline from the adjacent facilities at the landfill. Natural gas, supplied from the local ATCO Gas distribution system would be used as a backup fuel. The proposed power plant would be housed in a building constructed on previously disturbed land within the water and wastewater treatment plant site.
Aquatera is wholly owned by the City of Grande Prairie, County of Grande Prairie No. 1 and the Town of Sexsmith.
