On April 1, 2025, Sierra Club secured a win for clean energy and Mississippians. For over a decade, Sierra Club has been advocating for fair rules in Mississippi to encourage customer-sited clean energy like rooftop solar and storage. These clean energy measures help displace pollution and greenhouse gas emissions from fossil-fuel sources, protect against fuel price fluctuations, increase resilience, and jump-start the state’s clean energy economy.
In 2022, the Mississippi Public Service Commission issued rules to encourage customer-sited energy generation in the state. The rules include three important programs that provide financial incentives for customers with low-moderate income, for schools, and for residential battery installation. These three programs are key to attracting solar installers to the state.
However, in April 2024, after the make-up of the Commission changed, it voted to suspend these three important programs without any public notice or input. Sierra Club swiftly took action, filing a lawsuit to challenge the suspension. After months of delays, legal briefings and hearings, the Court rejected the Commission’s arguments that Sierra Club had no right to appeal the case, and granted Sierra Club’s motion, ordering the Commission to provide its administrative record. Instead, the Commission changed course and reinstated the suspended financial incentive programs for customer-sited solar on April 1, 2025. This reinstatement is a complete victory for Sierra Club and for Mississippians.
Sierra Club is represented by Sierra Club Environmental Law Program Senior Attorney Andrea Issod and local attorney Robert Wiygul. Mississippi Chapter Director Louie Miller leads coalition advocacy efforts.
