Power Generation

We produce the power that keeps your lights on.

The Origin of Your Electricity

We generate reliable, affordable electricity from a range of sources. In 2017, across our eight-state service area, 40 percent of our electricity came from carbon-free sources: wind turbines, solar panels, hydroelectric plants and nuclear plants. The rest is produced at thermal power plants where coal, natural gas, oil or biomass are used to heat water into steam to drive a turbine that produces electricity.

In total, our plants are capable of producing more than 17,000 megawatts (MW) of electricity. One megawatt of power provides enough electricity to serve nearly 1,100 typical homes.

Our Power Supply

Xcel Energy

Upper Midwest (Michigan, Minnesota, North Dakota, South Dakota, Wisconsin)


Southwest (New Mexico, Texas)


The charts above provide a snapshot of all the electricity by fuel type on our system in 2017. We have included energy that Xcel Energy plants generated, energy that we purchased, and energy that we supplied or made possible for customers under Xcel Energy renewable energy programs — Windsource®, Renewable*Connect®, Solar*Rewards®, and Solar*Rewards Community®. We count wind, solar, other renewables and nuclear as carbon-free. 

For every megawatt hour of electricity that renewable sources produce, we receive a renewable energy certificate or credit (REC). Each year we retire RECs to comply with our state renewable energy standards or save RECs for future compliance. Based on market opportunities, we also sell some of our extra RECs and share any profits with customers. Learn more about RECs in our annual Corporate Responsibility Report.

Compare Fuel Costs

We generate approximately two-thirds of our power, and buy the remainder from other electricity suppliers to meet our Colorado customers’ energy needs. Xcel Energy’s ongoing efforts to reduce our costs play a big part in keeping your energy bills low.

Energy Saving Tip

Energy-efficient appliances and light bulbs may cost a bit more up front, but they can save big money over the life of the product. Plus, some energy-efficient equipment may be eligible for rebates to offset the initial cost.

Preventing Carbon Monoxide Poisoning

Install carbon monoxide detectors and annually hire a qualified contractor to inspect your home for proper ventilation.
