Ratepayer Affordability and Transparency in Energy Act of 2026

S 3839 would block state laws requiring specific renewable energy targets (like renewable portfolio standards) or tying utility market participation to such requirements. It directly affects state governments, local regulators, and utilities by preempting these mandates as "inconsistent" with federal grid reliability goals. The bill's key mechanism is federal preemption, voiding any state law that mandates renewable energy percentages or conditions utility operations on compliance with such rules. It does not prevent states from owning or operating renewable energy facilities themselves, but would override state climate policies that impact grid planning or cost structures.
