We generate reliable, affordable electricity from an increasingly cleaner mix of energy sources. Across our eight-state service territory, 38% of the electricity on our power grid in 2018 came from carbon-free sources: biomass, hydroelectric and nuclear plants, wind turbines and solar panels. The rest was generated by fossil fuels, including coal and natural gas.
In total, the plants we own are capable of producing more than 18,000 megawatts of electricity. One megawatt of power provides enough electricity to serve nearly 1,100 typical homes.
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.
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.
