Consumer group sues electric rate regulators

MADISON, Wis. (AP) — A utility consumers group has filed a lawsuit against state regulators challenging a June decision to permit Wisconsin Power & Light to give industrial customers discounts on electric rates.

The Citizens Utility Board complains the discounts could drive up rates for residential customers to make up the difference.

Officials at the Public Service Commission didn’t immediately return a message. Steve Schultz, a spokesman for WP&L parent company Alliant Energy, had no immediate comment.
