Siemens Gamesa Renewable Energy will conditionally supply SG 14-222 Direct Drive offshore wind turbines to the 2,640 MW Dominion Energy Coastal Virginia Offshore Wind (CVOW) commercial project.
This project will be home to Siemens Gamesa’s latest offshore turbine variant having the capability to produce up to 15 MW with a 222-metre 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.
Siemens Gamesa was named as the preferred turbine supplier for the CVOW commercial project in January 2020.
The company said that it continues to work 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 US market are expected to be made within the next year, the turbine maker said.
“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 ,” said Andreas Nauen , CEO of the Siemens Gamesa Offshore Business Unit.
”In these turbulent times, where the winds of change are stronger than ever, and we’re thrilled to join forces to create even more renewable energy for generations to come.”
The turbine’s 222-meter diameter rotor, just shy of the length of the USS Wisconsin, one of the largest battleships built by the US Navy and currently residing in Virginia, uses the new Siemens Gamesa B108 blades.
Nearly 50 feet taller than the Statue of Liberty, each 108-metre long IntegralBlade is cast in one piece using patented Siemens Gamesa blade technologies.
At 39,000 m2, the turbine’s swept area is equivalent to approximately seven NFL football fields. It allows the SG 14-222 DD to provide an increase of more than 25% in Annual Energy Production compared to the SG 11.0-200 DD offshore wind turbine, rated at 11 MW with a 200-metre rotor, according to Siemens Gamesa.
Furthermore, the new offshore turbine features a comparatively low nacelle weight at 500 metric tons. This enables Siemens Gamesa to safely utilize an optimized tower and foundation substructure compared to a heavier nacelle, reducing costs per turbine by minimizing sourced materials and transportation expenses.
“It’s only fitting that the U.S.’s largest offshore wind project will feature the largest installation announced to date of Siemens Gamesa’s largest offshore wind turbine. We are proud to partner with Dominion Energy on such a significant project,” said Steve Dayney , Head of Offshore North America at Siemens Gamesa Renewable Energy.
“The offshore industry is emerging in the U.S. and with this agreement and this new product, we are positioned to significantly advance the growth of the industry and provide clean energy for many generations to come.”
Dominion Energy’s commercial offshore wind project expands on knowledge gained through the two-turbine,12 MW CVOW pilot project which will be installed within a research lease area adjacent to the site of the 2,640-MW commercial project.
It is the first offshore wind project to be built in US 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.
“Siemens Gamesa is a global leader in offshore wind technology and these new state-of-the-art wind turbines will help us provide the clean, affordable energy our customers expect and support the Commonwealth’s commitment to clean energy generation, firmly placing Virginia as a leader in offshore wind,” said Mark D. Mitchell , Dominion Energy Vice President of Generation Construction.
Earlier today, Siemens Gamesa announced Taiwan’s Hai Long Offshore Wind as the first developer to select the newly launched SG 14-222 DD turbine.
