Texas Utility Plans Battery Fix for Wavering Wind, Solar

Oncor Electric Delivery, owner of the largest power-line network in Texas, wants to spend more than $2 billion on batteries to solve the problem of fluctuating output from wind and solar.

The company is asking state legislators to change a law that prevents it from owning power plants before it invests in battery storage. It will then propose a spending plan to regulators “within months,” Chris Schein, a spokesman for Dallas-based Oncor, said in a phone interview today.
