The parent company of West Penn Power will ask Pennsylvania regulators today to allow it to raise rates across its four utility providers, including a 5.7 percent rate increase at West Penn Power.

If approved, the new rates could take effect as early as June 27. It would be the company’s second rate hike in as many years.

First Energy settled a rate increase request last year with the state Public Utility Commission that increased rates by about 13 percent. The company originally had asked for a rate hike of 14.7 percent. It was the first time the company had requested an increase to its base distribution rates in 20 years.

If approved, the total bill for an average residential customer would increase 9.64 percent, or $10.89, for a monthly total of $123.88. The bill for a commercial customer would increase 1.8 percent, or $16.58, for a monthly total of $959.86. The bill for an industrial customer would increase 0.8 percent, or $4,191.28, for a monthly total of $548,425.83.

Scott Surgeoner, a First Energy spokesman, said the proposed rate hikes were “aimed at enhancing electric system reliability for more than two million customers across the state.”

The plans include modernizing the company’s distribution grid with smart technologies that can prevent or shorten outages, additional tree trimming activities to protect poles and wires, and updating tablets and smart phones used by field staff to streamline work to restore power to customers.

“Today’s requests will allow our utilities to build on our progress in serving our customers, including ongoing maintenance for the new equipment and facilities we have added over the past several years,” said Lina Moss, the president of Pennsylvania operations for FirstEnergy.

The company’s request totals $439 million across its four Pennsylvania-based utilities

West Penn Power has about 720,000 customers in 24 counties in Pennsylvania. First Energy owns 10 electric distribution companies in Ohio, Pennsylvania, New Jersey, West Virginia, Maryland and New York.
