CHARLESTON, W.Va. (AP) -- West Virginia Citizen Action Group has joined the organizations objecting to Mon Power's proposed purchase of a coal-fired power plant.
The group says the $1.1 billion deal would raise rates for all but the largest industrial customers by 6 percent.
Activist Gary Zuckett says Ohio-based FirstEnergy would be the biggest beneficiary.
The Energy Efficient West Virginia coalition also opposes the deal with a sister company, Allegheny Energy Supply. Both are FirstEnergy subsidiaries.
They want to transfer full ownership of the Harrison Power Station in Haywood to Mon Power, which owns 20 percent.
In exchange, Mon Power would sell its 8 percent share of the Pleasants Power station at Willow Island to AE Supply, giving that subsidiary 100 percent ownership.
The Public Service Commission is holding hearings in Charleston May 29-31.
