PJM reviews system impacts of 1,152-MW gas project in Ohio

PJM Interconnection said in an undated study on its website, based on an Oct. 31, 2014, queue request (queue #AA1-123), that an unnamed developer is pursuing an 1,152-MW power project in Ohio.

“The Interconnection Customer (IC) is proposing to install an 1152MW (1105MW Capacity) natural gas facility to be located in Columbia County, OH interconnecting into the [American Transmission Systems Inc.] area,” said the study. “This means that the remaining 47MW can be curtailed should a system reliability constraint occur. The IC has proposed in-service date is for December 1, 2020.

“This Generation Interconnection Feasibility Study provides analysis results to aid the IC in assessing the practicality and cost of incorporating the facility into the PJM system. This study was limited to load flow analyses of probable contingencies. If the IC elects to pursue a System Impact Study, a more comprehensive analysis will be performed.

“Point of Interconnection AA1-123 will interconnect with the ATSI transmission system at one of two options. Option 1 is to connect at Highland–Sammis 345kV line. Option 2 is to connect at the simultaneous tap of Sammis–Boardman, Toronto–Dobins and Toronto–Nevada 138kV lines.”

Initial PJM studies like this one don’t include the names of the power plant developer, with later studies, like the System Impact Study mentioned above, having those names. Notable is that “Columbia” County is an apparent typo, since the grid infrastructure mentioned is in and around Columbiana County, Ohio, which is right next to the state line with Pennsylvania. There is no Columbia County in Ohio.
