For current customers and for future generations, CU must plan well in advance to make sure that the power is there when you need to “flip the switch” in your home or business.
The latest part of this power supply plan adds reliable, affordable, responsible power generation, at the existing Southwest Power Station, to meet growing community demand for power.
