The dance between utilities commission and energy providers changes faster than a do-si-do

The utility commissioners were engaging in an exercise of what-ifs. They regulate Xcel, which is responsible for more than 60% of the state’s electrical sales, and Black Hills Energy, also an investor-owned utility. Periodically, those utilities must submit plans to show how they intend to meet demands. Part of the dance between regulators and utilities is creation of models that seek to depict future trends.
