SOUTHERN COLORADO (KOAA) — Starting July 1, average monthly natural gas bills for Black Hills Energy customers will decrease slightly in western Colorado and increase slightly in the eastern part of the state.
The Gas Cost Adjustment (GCA) which is filed quarterly, was recently approved by the the Colorado Public Utilities Commission (CPUC) to reflect the projected cost of natural gas for the next three months.
In western Colorado, average bills will decrease by around 1.5% because of an adjustment over the last quarter. The monthly bill in eastern Colorado will rise an average of 3% to 4.5% due to increased natural gas costs.
