The Alberta Utilities Commission said in a Feb. 3 notice that it will take comment until Feb. 29 on an application from ATCO Power Canada Ltd. to construct and operate a 7.1-MW plant at Apache Canada Ltd.’s House Mountain Gas Plant and to interconnect the power plant to the Alberta Interconnected Electric System.
The plant would consist of five 1.42-MW natural gas-fired reciprocating engines. ATCO Power indicated that the power plant would replace a temporary 4.96-MW power plant that was approved in March 2015. The power plant would interconnect via ATCO Electric’s distribution system.
Apache’s House Mountain Gas Plant processes hydrocarbons from the House Mountain Field, a development that has been in active since the 1970s. In an effort to better utilize the production at House Mountain, mitigate the amount of sales gas that is being flared, and reduce large vehicle traffic on local roads, ATCO Power and Apache permitted, constructed and are currently operating a temporary power plant at the House Mountain Gas Plant. This facility consists of four, natural gas-fired reciprocating engines, each with an operating capacity of 1.24 MW, for a total installed capacity of 4.96 MW.
Over the past year, ATCO Power and Apache have developed a Permanent Power Plant solution that will replace the temporary plant. The permanent plant is proposed to consist of five Jenbacher JGS420 natural gas-fired reciprocating engines, each with an operating capacity of 1.42 MW, for a total installed capacity of 7.1 MW.
This permanent plant has a proposed in-service date of May 1, 2016. It is important this proposed in-service date is met due to commitments made to Alberta environmental regulators with respect to flaring, said the December 2015 application.
