Southwestern Electric Power Co. said Tuesday it had asked the high court for a rehearing in the case decided May 13.
The ruling said the state Public Service Commission had improperly held separate hearings on the need for the electricity that would be provided by the proposed John W. Turk Plant in Hempstead County, and on on the plant itself.
"Determining need for additional power is integral to determining the basis for the need of the proposed facility," the decision said. The ruling sent the case back to the PSC.
SWEPCO, a subsidiary of Ohio-based American Electric Power, has 464,000 customers in Arkansas, Louisiana and Texas.
