66 Pa.C.S. § 525

The commission may prohibit a public utility from discontinuing an electric generating unit from normal operation if the commission determines that it would be technically feasible and cost effective for the utility to sell the unit or the power from the unit to another utility and if the commission determines that it would be cost effective for the other utility to make such a purchase. The commission may also order the sale of the unit or the power from the unit if the commission determines that such a sale would be technically feasible and cost effective for both the selling and buying utilities.
