Duke Energy Carolinas and Duke Energy Progress ranked among the nation’s worst
DENVER – A report released this week by the Sierra Club faults dozens of utilities that provide a major chunk of U.S. electric generation for failing to speed up their decarbonization efforts.
“For the sake of our communities and planet, we must do everything in our power to create a clean, renewable electric grid by 2030,” the Sierra’s Club’s “Dirty Truth” report says. “Utilities must lead this transition, but our research shows they are wholly unprepared to do their part. Clean energy is reliable and affordable; electric utilities have no excuse to delay and no time left to waste.”
The report, released Monday, is an update of a 2021 study the group did. The Sierra Club analyzed plans of 77 utilities that collectively supply about 40% of U.S. electric generation and gave out letter grades based on how well utilities, many with their own clean energy goals, were working to decarbonize.
“Most are still not on the path to achieve 80% clean electricity by 2030. Of the 77 utilities we studied, nearly half of them (44%) made no progress or received a lower score than in our previous report,” the Sierra Club said. “This disappointing inaction occurred despite a tumultuous 18 months of grid reliability crises, blackouts, energy price spikes and extreme weather events; many of these trace their roots in large part to utilities’ stubborn reliance on expensive and unreliable fossil fuels.”
To determine the grades, the Sierra Club looked at the latest versions of the utilities’ integrated resource plans, documents that lay out how they will meet future electric demand, evaluating how quickly they intend to retire coal plants and penalizing them for plans that include building new gas generation.
“If a company includes multiple scenarios in their IRP, we use the scenario they denote as their preferred scenario,” said Cara Bottorff, a Sierra Club managing senior analyst. “If they do not denote a preferred scenario, we use the scenario that is the worst case for gas (i.e., the one that would add the most gas) to demonstrate the largest amount of gas that the company is considering building.”
Overall, 56% of the utilities examined improved their scores, 9% made no progress and 35% got worse grades. You can check how your local utility did here. Duke Energy Carolinas and Duke Energy Progress both received ‘F’ grades and ranked near the very bottom with scores of 4.33 and 4.94, respectively, out of a possible score of 100. Read more
