Xcel Energy. At every address we sampled across Boulder, Xcel handled both the electric and the gas. Colorado doesn't have retail energy choice, so this isn't something you shop for. Your address determines your provider, not the other way around. Because coverage can change right at the city's edges, run your specific address through the lookup before you assume anything.
Water and sewer run through Boulder Water at every address we sampled. A separate name from Xcel, which covers your electric and gas. So expect to deal with more than one provider when you set up service. Just outside the city, in unincorporated county or the foothills, the water and sewer picture can look different, including wells and septic, so confirm your exact address with the lookup.
It's Xcel. Boulder spent years pursuing its own municipal electric utility, hoping to break from Xcel and chase more aggressive clean-energy goals. After a long run of ballot measures and regulatory fights, the city ultimately signed a franchise agreement and stayed with Xcel. That's why Xcel shows up for electric and gas at the addresses we sampled today. Your water and sewer, though, still go through Boulder Water.
98% of Boulder electric checks pointed to Xcel Energy, making it the clear local answer.
