Net Metering
Missouri's net metering law lets you offset your electricity bill by exporting power your renewable energy system generates back to the grid; excess power is credited to your next bill at the utility's avoided cost rate, and these credits last 12 months. To connect, you submit an application with a wiring diagram and electrician certification—utilities must review and respond within 30 days for systems 10 kW or smaller, and cannot charge you special interconnection or standby fees beyond what non-generator customers pay (though you cover the cost of any metering equipment upgrades your system requires).
Missouri's Easy Connection Act streamlines interconnection for customer-generator systems up to 100 kW using wind, solar, hydroelectric, fuel cells, or other certified renewables, with standardized rates and no discriminatory fees; for systems 10 kW or smaller, you need only submit a single all-in-one document with a simple interconnection request and terms, and utilities have just 30 days to respond. Your customer avoids special standby or capacity charges, and the utility must apply identical rates and monthly charges as standard customers, making the value proposition straightforward and predictable.
Missouri's net metering program, administered under 20 CSR 4240-20.065, applies to all regulated utilities (Ameren, Evergy Missouri Metro, Evergy Missouri West, Liberty), municipal utilities, and rural cooperatives; eligible systems are capped at 100 kW and must be on customer-controlled premises primarily offsetting on-site load. Net excess generation is credited at avoided cost with a 12-month expiration, and the program counts toward utility renewable portfolio standard compliance; small systems (≤10 kW) use a simplified application with 30-day review, while larger systems (10–100 kW) have 90-day reviews, and customers only pay for metering equipment upgrades directly necessitated by their generation systems.

Program summary
Eligibility and Availability
Missouri enacted legislation in June 2007 requiring all electric utilities—investor-owned utilities, municipal utilities, and electric cooperatives—to offer net metering to customers with systems up to 100 kilowatts (kW) in capacity that generate electricity using wind energy, solar-thermal energy, hydroelectric energy, photovoltaics (PV), fuel cells using hydrogen produced by one of the aforementioned resources, and other sources of energy certified as renewable by the Missouri Department of Natural Resources.
Systems must be intended primarily to offset part or all of a customer's own electricity requirements, and must be located on premises owned, operated, leased or otherwise controlled by the customer. The estimated generating capacity of all net-metered systems counts towards the respective utility's fulfillment of its requirements under Missouri’s renewable portfolio standard.
If a customer's existing metering equipment is not capable of measuring the net amount of electricity produced or consumed, or if it is necessary for the utility to install "additional distribution equipment to accommodate the customer-generator's facility," then the customer must pay for these costs.
Net Excess Generation
Customer net excess generation (NEG) during a billing period is credited to the customer's next bill at a rate at least equivalent the utility's avoided cost rate. Credits expire 12 months after issuance without compensation.
Utilities must offer a net-metering tariff or contract that is identical in electrical energy rates, rate structure, and monthly charges to the contract or tariff that the customer would be assigned if the customer were not an eligible customer-generator. The tariff or contract cannot charge the customer-generator any additional standby, capacity, interconnection, or other fee or charge that would not otherwise be charged if the customer were not an eligible customer-generator.
Interconnection
For systems of 10 kW or less, applications must include an all-in-one document that includes a simple interconnection request, simple procedures, and a brief set of terms and condition.
