Dominion Virginia Power said June 21 that it has begun construction on its 1,588-MW Greensville County Power Station, immediately after the Virginia Air Pollution Control Board approved the station's air permit.

The air permit, issued on June 17, was the last regulatory hurdle the station had to clear before it could start construction.

"This is terrific news for Dominion, its customers, the Commonwealth, Greensville County and all of Southside Virginia," said Paul Koonce, chief executive officer for Dominion's Generation Group. "We are excited about the task ahead and are looking forward to getting this state-of-the art power station operating and providing energy to more than 400,000 customers by 2019."

Over its expected 36-year life, the station will save Dominion Virginia Power customers about $2 billion as a result of the company not having to purchase power from market sources. The Greensville County Power Station will be Dominion's second major generation project in the Southside area of Virginia. In April, the company began generating electricity from its Brunswick County Power Station. That 1,358-MW combined-cycle facility is located just five miles from the Greensville site.

The seven-person air board voted 5-0 to approve the permit, which has the strictest carbon limits in the nation. One member abstained and another was absent.

"The Air Board has approved and the Virginia Department of Environmental Quality has issued a very strict permit, which will require that our station be one of the most efficient and environmentally protective natural-gas fueled power stations in the world," said Pamela F. Faggert, Dominion's chief environmental officer and senior vice president sustainability.

PJM Interconnection in December 2015 filed with the Federal Energy Regulatory Commission an executed Interconnection Service Agreement with Virginia Electric and Power as both the power plant developer and the interconnecting transmission owner for the Greensville project. The Virginia Electric ISA facilitates the interconnection to the PJM transmission system of the Greensville Generating Facility, to be located in Greensville County, Va. It is to have a Maximum Facility Output of 1,681 MW. The ISA further indicates that Virginia Electric shall have Capacity Interconnection Rights in the amount of 1,630 MW.

The project site is at 2500 Rogers Road, Emporia, Greensville County. This is a 3x1 combined cycle facility. Under the ISA, on or before June 1, 2019, Virginia Electric must demonstrate commercial operation of all four generating units. The project is under PJM Queue Position #Z1-086. Dominion will interconnect the project starting at a new 500-kV Rogers Road switching station and build a 500-kV attachment line to a deadend structure at the Greensville generator substation collector bus.

Dominion Virginia Power is a subsidiary of Dominion Resources (NYSE: D), one of the nation's largest producers and transporters of energy. Dominion provides energy or products and services to more than 5 million customers in 14 states. It has a portfolio of approximately 25,700 MW of generation and 6,500 miles of electric transmission lines.
