PJM writes impact study for big, gas-fired project of Virginia Electric

PJM Interconnection issued a November 2014 System Impact Study, which is a mid-point in the generation project interconnection process, for the next big gas-fired power plant of Virginia Electric and Power.

Virginia Electric and Power is a unit of Dominion Resources (NYSE: D).

This 1,681-MW combined-cycle project would be located in Greensville County, Va. The project, under queue #Z1-086, will interconnect into the Virginia Electric and Power system via a new three breaker ring bus switching station that connects to the Carson-Heritage 500-kV line. The project in-service date in the study is Dec. 1, 2018, though that may change as the queue review process goes along.

Said the study: “The Queue Project Z1-086 was studied as a 1630.0 MW (Capacity 1630.0 MW) injection tapping the Carson-Brunswick 500 kV line in the ITO area. Project Z1-086 was evaluated for compliance with applicable reliability planning criteria (TP, NERC, NERC Regional Reliability Councils, and Transmission Owners) for summer peak conditions in 2017. The stability analysis used a 2019 model and 1681 MW injection. Queue project Z1-086 was studied with a commercial probability of 100%.”

The Federal Energy Regulatory Commission on Sept. 3 accepted PJM’s July 24 filing of an executed interim interconnection service agreement for this project, called the Greensville Combined Cycle Facility.

This project entered the PJM queue in October 2013. The utility during the course of this Interim ISA committed to various things, including outage planning with the System Operations Center to determine feasibility of completing all network upgrades needed prior to power plant startup.

Virginia Electric and Power already has a busy gas-fired project construction program. In construction and due to be fully operational by December 2014 is the 1,329-MW Warren County Power Station in Warren County, Va. Another in-construction project is the 1,358-MW Brunswick County Power Station in Brunswick County, Va., which is due to be fully operational in May 2016. The utility has not officially announced the Greensville project, but has hinted at a new power plant of about this size at an unspecified location in its latest Integrated Resource Plan.
