Dominion Virginia Greensville County Power Station

In 2016 Fluor was granted full notice to proceed on Dominion's combined-cycle, natural gas-fired power station, which will be the largest and most efficient natural gas-fueled power station in Virginia. This project follows the successful completion of Dominion's Bear Garden and Brunswick power stations in the state.



Client's Challenge

Dominion is building the 1,588-megawatt Greensville County Power Station, which will produce enough electricity to power 400,000 homes in Virginia at peak demand. The new power station is located on a 1,143-acre site on the Greensville and Brunswick County line in southern Virginia.

This new approach to clean energy also serves as a cost-effective and reliable step toward achieving the federal clean-air standards.

The power station will be a major boost for the region's economy. In its first year of operation, it is expected to provide up to $8 million in property taxes for Greensville County. Post-construction economic benefits are projected to amount to about $36 million annually, and about 166 jobs will be supported, with roughly half of these in Greensville County.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.

Fluor's Solution

Fluor was awarded a limited notice to proceed on Dominion's Greensville power station in April 2015. In July 2016 Dominion granted Fluor full notice to proceed with engineering, procurement, construction and commissioning on the project. This new project is Fluor's third successive project for Dominion.

The facility features three Mitsubishi Hitachi Power Systems Americas (MHPSA) 501 J advanced combustion turbine generators, followed by three Alstom Heat Recovery Steam Generators (HRSG) operating in combined cycle with one Alstom steam turbine generator. The design includes an 80-cell Air Cooled Condenser (ACC), and Thermal Energy Storage (TES) System. The TES system includes a field erected TES tank and chiller system which improves peak energy output during summer ambient conditions. Fluor will be continuing our attention to sustainable design with plans to achieve Leadership in Energy and Environmental Design (LEED®) certification for the Control and Administration building. Additionally, nearly three miles of new and/or upgraded roads will be put in place to support the craft population and heavy material deliveries.

Fluor's office in Charlotte, North Carolina, is leading the design effort with support from our office in the Philippines and global subject matter experts. Fluor's integrated team provides innovative designs, smart supply chain solutions and experienced construction and commissioning teams. AMECO, Fluor's equipment subsidiary, is providing construction tools and rentals.

Fluor anticipates 1,000 craft workers on site during peak construction. We continue our relationship with Southside Virginia Community College to develop and implement a welding training program.

Modular construction is planned for the project. HRSG and turbines will arrive as modules and assembled at the site. Fluor is self-performing both the design and assembly of modularized pipe racks and stair towers.

Fluor is also building infrastructure at the site to include power plants, roads, a water treatment facility and utilities. We are developing extensive road work to connect the site to the nearest U.S. highway.



Conclusion

The new, nominal Greensville County Power Station is expected to be completed by December 2018.
