Westar Energy will return $38 million to customers

? Westar Energy will be sending rebates to customers after collecting $38 million too much last year.

The rebates, which will average about $1.26 a month, come from Westar’s Retail Energy Cost Adjustment rider, which pays for fuel for Westar’s generating plants.

The rebates were detailed in filings with the Kansas Corporation Commission.

The Wichita Eagle reports a fuel charge means customers essentially pay the cost of Westar’s fuel, and the charge fluctuates every month. If Westar collects too much, customers get a rebate. If the utility collects too little, customers pay more.

In 2014, Westar charged customers just over $510 million for the fuel charge. But the company spent a little over $479 million.
