Xcel Energy to use soy oil in its transformers

Email

FARGO, N.D. (AP) - Xcel Energy says it will be the first large utility in the country to switch to soy-based transformers, using oil produced from domestic soybean crops.

The company now uses petroleum-based mineral oil, which is the industry standard and works well, Xcel spokeswoman Bonnie Lund said Thursday.

"We are aiming to minimize our impact on the environment while balancing that against cost and reliable service," Lund said. "We want a clean energy future."
