Siemens Gamesa Renewable Energy is set to supply SG 14-222 Direct Drive offshore wind turbines to 2,640-MW Dominion Energy Coastal Virginia Offshore Wind (CVOW) project.
Siemens Gamesa’s latest offshore turbine variant has the capability to produce up to 15 MW with a 222-meter rotor. The exact quantity of turbines to be deployed is subject to final project site conditions. All turbine installations are expected to be completed by 2026.
The agreement is subject to certain conditions including Dominion Energy’s final investment decision, governmental permitting, and other required approvals.
The project is expected to provide enough clean energy to power 650,000 homes at rated wind speed, avoiding 3.7 million tons per year of carbon emissions compared to fossil fuel-based power generation.
Siemens Gamesa works with local stakeholders to investigate a potential blade manufacturing facility for these turbines on the East Coast, potentially the first facility custom-built to manufacture components for the SG 14-222. Decisions on sourcing and supply chain to serve the U.S. market are expected to be made within the next year.
“Dominion Energy’s selection of the SG 14-222 DD offshore wind turbine for deployment is an important next step for the sizable project, the U.S. offshore wind industry, and the global offshore wind industry,” says Andreas Nauen, CEO of the Siemens Gamesa Offshore Business Unit.
Dominion Energy’s commercial offshore wind project expands on knowledge gained though the two-turbine,12-MW CVOW pilot project which will be installed within a research lease area adjacent to site of the 2,640-MW commercial project.
It is the first offshore wind project to be built in U.S. Federal waters and will utilize Siemens Gamesa’s 6-MW SWT-6.0-154 wind turbines. The pilot project is set to be online later this year.
