Energy Portfolio/Mix

CORE Electric Cooperative is committed to providing electricity that is both reliable and affordable.

We purchase wholesale power from a variety of sources and receive additional power from Comanche Unit 3, a supercritical, pulverized coal plant located in Pueblo and operated by Xcel Energy.  Learn more on our energy transformation page.

In the last several years, we have made significant investments in utility-scale renewables that make dependable energy available at or below our avoided cost, which is what CORE would otherwise pay for the same amount of energy from other sources. We also have interconnected to our grid nearly 11,000 rooftop solar systems that offer more than 66 megawatts of potential generation.
