Invenergy Thermal Development has proposed a combined cycle natural gas-fired facility located near the intersection of Henderson Road and Great Allegheny Passage North in Buena Vista, Allegheny County, Pennsylvania.
PJM Interconnection said in a May 2016 study on the project that the installed facilities will have a total capability of 541 MW with 513 MW of this output being recognized by PJM as capacity. The proposed in-service date for this project is June 1, 2020. This study does not imply a West Penn Power commitment to this in-service date.
This project, under PJM Queue #AA2-161, would have a connection from the West Penn Power transmission system to Invenergy’s facilities that will be provided by looping in/out the Yukon-Robins and the Wycoff-Springdale 138 kV lines to a to-be-constructed six-breaker ring bus substation. Invenergy is responsible for installing the 0.5-mile-long generator lead to the point of interconnection. Project AA2-161 was studied with a commercial probability of 100%.
A diagram in the study shows this as a 1×1 combined cycle facility, made up of a combustion turbine and a steam turbine.
The intent of this System Impact Study is to determine a plan, with approximate cost and construction time estimates, to connect the subject generation interconnection project to the PJM network at a location specified by Invenergy. The study is a mid-point in a queue process that eventually leads to the signing of an Interconnection Service Agreement. The project entered the queue in April 2015.
