The Virginia State Corporation Commission announced Wednesday that it will hold new hearings on a Dominion Energy proposal for new power lines in Prince William County, postponing a decision on the project that has been opposed by nearby residents for nearly two years.

Dominion wants to install 230,000-volt lines between Haymarket and Gainesville to serve a new computer data center complex in the area.

The commission ruled earlier this year that the 5.1-mile route could go through a neighborhood where the descendants of a former slave have lived for nearly 120 years.

In September, however, Dominion announced that route was no longer feasible, after Prince William County officials refused to grant permission for the utility to use county-owned land.

On Tuesday, the three-member commission said a hearing examiner will take in new testimony from Dominion and local groups opposed to the project.

The board will then use a report filed by the hearing examiner to make its decision, the commission said.
