The IRP decision comes a week after the Georgia Supreme Court denied a petition from the Sierra Club to review the PSC’s 2019 decision to allow the utility to charge their customers for coal ash pond closure costs.
Sierra Club has been litigating the matter for years, trying to ensure that Southern Company subsidiary Georgia Power does not have a carte blanche for charging ratepayers for its coal ash expenses, alleging that the utility knew its coal ash storage contaminates groundwater.
