The request is expected to affect distribution rates and would allow the company to begin to recover nearly three years of costs incurred for the improvement and expansion of its distribution system since its last rate request. By law, PPL Electric Utilities cannot recover those costs without approval of a rate increase from the commission.

David DeCampli, president of PPL Electric Utilities, said: “We will be requesting this increase so that we can continue to keep reliability strong for our customers, to step up efforts to replace aging infrastructure and to modernize our delivery system.”

While the company has not finalized how much of an increase it will request, it would be no more than $115m, or about a 2.5% increase in the company’s total retail revenues, Mr DeCampli said.

PPL Electric Utilities is a subsidiary of PPL Corporation that provides electricity delivery services to about 1.4 million customers in Pennsylvania.
