AEP-LOGORICHMOND, Va. (AP) _ Appalachian Power is proposing ways for its Virginia customers to reduce energy usage and demand. The utility on Friday filed a request with the State Corporation Commission seeking approval for four residential programs and two for commercial and industrial customers. The residential programs would provide home assessments and incentives for long-term energy reduction; provide free pickup and cash incentives for removing second refrigerators or freezers from the power grid; give incentives if new manufactured housing is built to efficiency standards; and offer retail rebates and markdowns for high-efficiency lighting and appliances.  A financial incentive for commercial and industrial users would tie to specific results from installing high-efficiency lighting and heating and cooling equipment. Another would provide rebates for certain larger energy conservation projects. Appalachian Power has about 500,000 Virginia customers.
