Study says a regional energy market could prevent blackouts

In this mention

A study by environmental and renewable energy groups, including the Southern Alliance for Clean Energy, argues that regional energy markets and expanded solar capacity could have prevented December 2022 blackouts in the Carolinas. The analysis shows that solar performed well during the outages and that integrated regional transmission systems like PJM in the Mid-Atlantic avoided blackouts, while Duke Energy and TVA's vertically integrated structure left them vulnerable. South Carolina is studying whether to separate power generation and distribution, though Duke Energy opposes the change.
