South Dakota regulators gave Black Hills Energy the go-ahead Friday to return another $906,000 to their customers in the western part of the state.
The money is the latest true-up from the 2017 federal tax cuts.
The Rapid City-based company gave back more than $7.6 million last fall to customers in South Dakota.
Now there’s another $850,000 to return after filing the 2018 taxes.
There’s also $57,000 remaining from the October round because customers had left the company’s system.
The state Public Utilities Commission agreed Black Hills Energy can give customers credit on their February bills.
