Virginia City Hybrid Energy Center
Shaw helps clients generate electric power in an environmentally sound and cost-effective process by using advanced technologies and expertise in engineering, procurement and construction (EPC). Near St. Paul, Va., Shaw is providing design and EPC services for Dominion Virginia Power's new, 585-MW clean coal-fired generating plant.
The Virginia City Hybrid Energy Center will be one of the cleanest coal plants of its kind, capable of burning a diverse mix of fuels including run-of-mine coal, waste coal and wood waste, according to Dominion. Clean coal technologies, combined with modern post-combustion controls, result in low emissions of sulfur dioxide, nitrogen oxide, particulate matter and mercury.
At the plant, two circulated fluidized bed (CFB) boilers will supply steam to a single turbine generator. The CFB combustion process recirculates unburned fuel, which will increase heat transfer and performance. Technologies such as selective non-catalytic reduction systems and the use of limestone, coupled with a dry scrubber, further eliminate environmentally harmful chemicals.
Shaw construction:
- All foundations, buildings, steel, vessels and tanks
- Air-cooled condenser, steam turbine generator and steam generator
- Electrical switchyard, direct process equipment and a material handling conveyor
The plant is scheduled to go into commercial operation in the summer of 2012. Once fully operational, it will produce enough electricity to supply approximately 146,000 residential customers.
