Although 2021 is only halfway through, state utility regulators and regional grid operators have had their hands full considering issues at the cutting edge of the energy transition.

How can customers be helped to make smarter energy decisions? These questions and more are on the docket in 2021, and Advanced Energy Economy has been tracking how regulators are tackling these complex issues. Even just halfway in, the regulatory trends from across the country suggest that 2021 will be another transformational year for advanced energy.
