Our products and services differ based on state. Please select your state (or the state you're interested in) from the list to the left.
Why do our products and services differ based on state? Because our business is regulated by state. We have regulated operations in eight Western and Midwestern states. The different regulatory body for each state we serve determines what products and services we deliver in that state.
In the 1800s up until the mid-1900s, before natural gas was available as an energy source, gas was manufactured using coal, oil and/or petroleum. It was used primarily for heating, cooking and street lighting. EPA estimates that more than 50,000 manufactured gas plants (MGPs) operated in the United States between 1815 and 1960 and were owned by municipalities and corporations, including predecessor companies to today’s electric utilities. These plants produced a variety of waste products, including coal tar. Some of the waste products were sold or disposed and some were left at the plant site.
Given the extensive history of our operating companies—some going back more than 100 years—Xcel Energy has inherited several legacy manufactured gas plant sites. All of these plants were closed and dismantled and some of the properties were sold. Over the years, we have worked cooperatively with environmental agencies and communities to successfully investigate and/or remediate former MGP sites.
