Modifies provisions for net metering

HB 2537 modifies Missouri's net metering rules for small renewable energy systems. It requires utilities to offer net metering to eligible customers (like homeowners with rooftop solar under 100 kW) on a first-come basis until systems reach 5% of the utility's peak annual demand. If a utility exceeds 1% of its peak demand in a single year, it can pause new enrollments until the next year. Customers generating excess power receive credits based on the utility's "avoided fuel cost" (the cost saved by not buying that power), applied to future bills. This bill updates existing rules without creating new programs, focusing on access limits and billing mechanics for customer-generators.
