The Sierra Club's latest Dirty Truth Report, its sixth annual assessment, gives Mississippi Power a score of 44 out of 100. The report evaluates utilities nationwide on how aggressively they are retiring coal plants, how much new gas capacity they plan, and how much renewable energy they are adding. Mississippi Power's low score places it among the laggards in the transition to cleaner generation.
According to the report, the utility is failing to lower both costs and pollution. The grading criteria reflect a growing consensus that reducing coal and gas dependence is essential for both economic and environmental performance. Mississippi Power's continued reliance on fossil fuels, as measured by the report, suggests it is not keeping pace with industry trends or regulatory expectations.
While the report is based on a single source—the Sierra Club's analysis—it provides a clear snapshot of the utility's current trajectory. The score of 44 indicates significant room for improvement in retiring coal, moderating gas expansion, and scaling up renewables. As pressure mounts on utilities to cut emissions and stabilize rates, Mississippi Power's performance will likely face continued scrutiny.
