Residential electricity consumers would see a $2.35 increase in a typical monthly electric bill under a proposed settlement of a rate case filed by Oncor Electric Delivery, the major transmission and distribution company serving North Texas.

Oncor spokeswoman Catherine Cuellar told the Star-Telegram late Friday that the company "has an agreement in principle" with intervenors in the case, including the Steering Committee of Cities Served by Oncor, which includes more than 140 cities, among them Arlington, Fort Worth and other Tarrant County cities.

Under the settlement, Oncor's annual revenue would increase by $136.7 million, Cuellar said.

The $2.35 increase would be for a household using 1,300 kilowatt hours of electricity a month, she said. That represents a 5.7 percent increase from the $41 that Oncor currently receives as its share of a typical residential electric bill at the same usage.

The increase would occur in two steps, on July 1 and Jan. 1. The first would produce about $93 million of the revenue increase. After the second, the full $2.35 monthly increase would kick in.

The settlement would give Oncor slightly less than half of what it sought in filing its case with the Texas Public Utility Commission in January.

Oncor asked for a rate hike that would have boosted annual revenues by $350 million.

That would have resulted in a $5 jump in a typical residential customer's electric bill and a 12.2 percent increase in Oncor's share of the bill.

Cuellar said Friday that Oncor expects to finalize the settlement "over the next couple of weeks." It would then ask the PUC to approve.
