TOPEKA, Kan. (AP) — Westar Energy will return millions of dollars to Kansas energy customers under a settlement with regulators. The Topeka Capital-Journal reports that the Federal Energy Regulatory Commission has approved the settlement between Westar Energy and the Kansas Corporation Commission. The settlement lowers the return on equity the company had previously included in its Transmission Delivery Charge tariff. On customer bills, it shows as a line item "Transmission Delivery Charge," and is designed to allow utilities to recover money spent on transmission. The exact refund is being determined in the company's rate department, but for 2015 it was $14 million. Westar says customers won't immediately see the refund because there are still steps in the process to be completed.
