ATCO Power Canada Ltd. won a March 24 approval from the Alberta Utilities Commission to construct and operate a 4.96-MW natural gas-fired power plant at Apache Canada Ltd.’s House Mountain gas plant.
This site is located approximately 50 kilometers southwest of the town of Slave Lake. This application was registered on Jan. 28. ATCO Power also requested approval to connect the power plant to the Alberta Interconnected Electric System. Both the plant and the interconnect were approved in the March 24 order.
ATCO Power submitted that in late 2013 a sales gas pipeline was taken out of service due to integrity concerns resulting in zero sales gas takeaway capacity for the House Mountain gas plant. Apache Canada arranged for the sales gas to be trucked to another Apache Canada facility. The remaining sales gas produced at the plant is flared to the maximum amount allowed. In order to better utilize the sales gas and mitigate the amount of gas being flared, ATCO Power proposed to construct a temporary 4.96-MW power plant, consisting of four 1.24-MW natural gas-fired generators.
ATCO Power stated that the power plant would operate until a permanent pipeline solution is restored, which it estimated to be a period of six months to one year. The power plant would connect to the Alberta Interconnected Electric System via ATCO Electric’s 25-kV distribution system.
ATCO Power submitted that the generators would be housed within sea-cans, which would sit on rig mats and have temporary containment berms installed around them.
