Dominion Virginia Power made it official March 26 on its next big gas-fired power plant, announcing that the company is proposing to build an approximately 1,600-MW power station in Greensville County, Va.
Work has been underway on this project well before this formal announcement.
- Transcontinental Gas Pipe Line Co. LLC (Transco) applied March 23 at the Federal Energy Regulatory Commission for a certificate of public convenience and necessity authorizing it to construct and operate its Virginia Southside Expansion Project II (VSEP II), which will serve the Greensville plant.
- PJM Interconnection issued a November 2014 System Impact Study for a 1,681-MW combined-cycle project that would be located in Greensville County. The project, under queue #Z1-086, will interconnect into the Dominion system via a new three breaker ring bus switching station that connects to the Carson-Heritage 500-kV line.
The station, which would cost more than $1 billion, would be a combined-cycle facility consisting of three gas-fired combustion turbines and a steam turbine, said Dominion in the March 26 announcement. Pending regulatory approval, the station would create more than 1,000 jobs at the peak of construction and be operational in 2019 to meet projected demand growth. The station will have about 45 full-time employees.
“We are proposing to construct the largest and most efficient natural-gas fueled power station in Virginia to bring our customers reliable, low-cost energy,” said David Christian, chief executive officer for Dominion Generation.
“This project is another great step toward the clean energy portfolio we need to build a new Virginia economy,” said Virginia Gov. Terry McAuliffe. “This plant will offer clean, reliable and low-cost energy to Virginia homes and businesses and at the same time, the jobs and tax revenue generated will be a positive boost for Greensville County and all of Southside Virginia.”
The company plans to submit its application for a Certificate of Public Convenience and Necessity to the Virginia State Corporation Commission in July. Construction would begin in mid 2016, subject to SCC and environmental approvals.
The company selected the site because of its proximity to transmission and natural gas lines, water supply, railroads and major highways. The station would be served by a Transco natural gas line that is being extended to the site and the proposed Atlantic Coast Pipeline (ACP) that will cross the station property when that pipeline is built. This will improve operational reliability by providing flexibility and redundancy in procuring the station’s fuel supply. The ACP will be critical to providing reliability, infrastructure, fuel supply diversity and helping to keep fuel costs low not only for this plant but the entire generation fleet.
The 1,143-acre site straddles the Greensville/Brunswick County line with 740 acres in Greensville County. The company already has filed the necessary zoning permit applications with both jurisdictions. The applications also seek to have the site approved for the construction of a future large-scale solar project.
In November 2014, Dominion issued a request for proposals (RFP) to begin delivery of electricity in the 2019/2020 timeframe. This is to support Dominion’s generation needs as presented in the company’s Integrated Resource Plan. After a thorough and objective evaluation of those proposals, this power station in Greensville County was selected as the option most beneficial to customers.
Dominion is currently building a 1,300-MW combined-cycle power station just 4.5 miles away in Brunswick County that is about 58% complete.
