West Virginia regulators say they need more time to review a proposed settlement before deciding whether to approve a multistate power line that would run through part of Virginia.

State law requires the West Virginia Public Service Commission to issue a decision on the power line by May 3. But the commission wants to push back the deadline until at least August.

The PSC says it needs to obtain comment on the proposed settlement from other parties in the case. The agency says it also needs to hold a hearing.

Allegheny Energy subsidiary Trans-Allegheny Interstate Line Company wants to build the 240-mile power line between Washington County, Pennsylvania, and Loudoun County, Virginia. It would pass through six counties in West Virginia.

The proposed settlement calls for Allegheny to give its West Virginia customers a seven-year reprieve from costs associated with the power line.
