Before your first night in a new Denver place, run this quick checklist. It covers your Xcel energy start and your separate Denver Wastewater Management water-and-sewer setup.
For both, it's Xcel Energy. That's what came up at every address we sampled across Denver. Colorado doesn't have retail energy choice, so there's no separate company to shop for; the same utility that serves your street handles your power and your natural gas alike. To confirm what serves your specific place, run the address through the lookup before you schedule a start date.
No. Colorado isn't a deregulated "choice" state, so there's no marketplace of retail suppliers to pick from the way there is in Texas or parts of the Northeast. Whoever serves your address is who bills you, and in Denver that's Xcel Energy for both electricity and natural gas. So instead of comparing companies, your move-in job is simply getting service started in your name at the right address. The lookup confirms who that provider is.
Water and sewer show up under Denver Wastewater Management at the addresses we sampled. A different provider than the Xcel service covering your energy. Since it's a separate outfit, plan on handling it on its own rather than folding it in with your power setup. If you're not sure which accounts apply to your new place, the lookup breaks utilities down by type for your exact address, so you can see water, sewer, gas, and electric side by side.
For electric in Denver, the answer is Xcel Energy at 100% of addresses we checked.
Enter the Denver street address in the lookup; you'll get the electric, gas, water and sewer lineup plus next-step links.
