Alberta okays uprate for Grande Prairie Generation facility

The Alberta Utilities Commission on Nov. 27 approved an application from Grande Prairie Generation Inc. to up the capacity of its Northern Prairie Power Plant, located in the county of Grande Prairie, from 85 MW to 105 MW.

The application was registered on March 30. No submissions were received in response to a notice about this application.

Grande Prairie Generation stated that the existing power plant consists of one General Electric Model MS7001/EA (Frame 7EA) natural gas-fired turbine generator unit, with a nominal output of 85 MW. The company submitted that it had upgraded the turbine control system so that the efficiency of turbine was improved. The turbine-generator unit is capable of generating electric energy at 105 MW under its current configuration. However, the maximum generating capability of the power plant was limited to 99 MW because there were transmission system constraints in the area.

Grande Prairie Generation applied to the Alberta Electric System Operator (AESO) to remove the operating constraints, in order to operate the power plant at its maximum generating capability of 105 MW. Grande Prairie Generation stated that the proposed increase in approved generating capability would not require any further design change to the power plant.

The commission approved the change, noting that Grande Prairie Generation can’t operate the plant at its full capability of 105 MW until it has received an authorization from the AESO to operate beyond the current constraint of 99 MW.

Grande Prairie Generation is a wholly-owned subsidiary of Exelon Corp. (NYSE: EXC).
