Fair Allocation of Interstate Rates Act

S 3287, the Fair Allocation of Interstate Rates Act, prevents transmission providers serving customers across multiple states from charging out-of-state consumers for electric transmission facilities built to implement a specific state's energy policy (like renewable mandates). It prohibits cost allocation to consumers not residing in the state whose policy led to the facility's construction, unless that consumer's state explicitly consents. The bill establishes that benefits of such facilities are presumed to accrue only to residents of the implementing state, making them the default "cost causers." This directly affects interstate electricity providers and consumers in states with differing energy policies, requiring new cost-allocation rules within 180 days of enactment.
