Dominion Virginia Power announced Thursday that it is undertaking a study of what it would take to build a high-voltage underwater transmission line from Virginia Beach into the Atlantic Ocean to support potentially multiple offshore wind farms.

The company said in a statement that it sees this step as the first of many, with the ultimate goal being the design, construction, operation and maintenance of a line necessary to make offshore wind resources available to its customers.

“Virginia has excellent resources for offshore wind energy,” Scot C. Hathaway, vice president-transmission, said.  “It makes sense for us to begin a preliminary scoping study of a transmission line and how it could make the offshore wind industry in Virginia viable, without regard to issues of rates, timing and integration into the PJM Interconnection regional transmission grid.”

Dominion plans to complete the study this year. The Virginia State Corporation Commission would have to approve any power line project as well.

Richmond-based Dominion Virginia Power is a subsidiary of Dominion. In a study last year, Dominion found that it is possible to interconnect large-scale wind generation facilities up to a total installed capability of 4,500 megawatts. The study said 1,500 megawatts of generation into a Virginia Beach substation would not be expected to create transmission deficiencies.
