Missouri Plug-In Bills
- HB 2528 (2026): The bill was filed by Rep. Mark Matthiesen wants portable solar devices (UL or NRTL certified, 120-volt outlet) of up to 1,200 W freed from PSC rules covering net metering and interconnection. The last action came on May 15, 2026, when the House Emerging Issues committee received the referral; it never reached the floor. See the bill page
- HB 2444 (2026): A similar bill by Rep. Mark Boyko (no approval from the utility, no fees and no extra equipment; exempt from net metering). On May 15, 2026, the last action was a referral to the House Emerging Issues committee, and the bill never made it to the floor. Bill page
Missouri's Current Rule
Hooking up: The Net Metering and Easy Connection Act (RSMo 386.890) sets the process. A customer-generator files an application with its retail electric supplier, including a wiring diagram and a plan. For systems of 10 kW or less, no extra controls or tests apply, and the supplier must reply within 30 days.
Net metering: Suppliers must provide it for renewable systems of up to 100 kW until 5% of their peak load is reached. Extra power earns a credit of at least the avoided fuel cost, and that credit carries to the next bill.

Missouri Facts to Know
- In Missouri, the utility credits net excess power only at its avoided fuel cost. That rate is well below the retail price, so using the power yourself matters more than exporting it.
- In 2024, the average home in Missouri paid 12.91 cents/kWh. That's a fairly low rate. Payback is slower.
