MUNICH, Germany Siemens Energy will supply the main electrical equipment for the grid connection for Dominion Energy’s Coastal Virginia Offshore Wind (CVOW) commercial project.

The 2.6-GW wind farm, which is expected to include up to 180 turbines, is the largest offshore wind project under development in the US.

The company will deliver the high-voltage electrical equipment for the three 800-MW offshore substations. These platforms will collect the low voltage energy generated by the wind turbines and transmit it at a higher voltage to shore.

For each substation, the company will provide three power transformers, three shunt reactors, one medium-voltage gas insulated switchgear (GIS) and three high-voltage GIS systems to Semco Maritime.

According to Siemens, the system solution is specifically designed to reduce both the size and weight of the platform, lowering the need for the use of steel and making it more resource- and cost-effective.

Once fully commissioned in 2026, the CVOW commercial project is expected to prevent up to 5 million tons of CO2 emissions annually and power up to 660,000 households in Virginia.
