Net Metering

Eligible residential and non-residential electric customers of Ameren Illinois are able to apply for authorization to net any electricity they generate qualifying renewable resources against the electricity supplied to them by Ameren Illinois or their retail electric supplier.

See the Net Metering Rule (83IL Admin Code, Part 465) for details.

To qualify, residential and non-residential customers must own or operate a renewable fuel-powered generator of 2,000 kW capacity or less, which is located on the customers’ premises and is used to offset some or all of their electric usage. Eligible renewable fuels are solar, wind, dedicated crops grown for electricity production, anaerobic digestion of livestock or food processing waste, fuel cells or microturbines powered by renewable fuels, hydroelectricity, agricultural residues, livestock manure, landscape trimmings and untreated and unadulterated wood wastes.

Customers using renewably-fueled generators with nameplate capacities larger than 2,000 kva may qualify to receive compensation through Rider QF-Qualifying Facilities

Compensation for Customers using Renewable Fuels to Generate Electricity
The Net Metering Rule requires utilities and retail electric suppliers to provide financial credits for renewable fuel-generated electricity that offset the amounts that otherwise would have been supplied by the customer’s electricity provider during a billing period. For customers served under Delivery Service tariffs DS-1 or DS-2, credits in excess of their monthly usage will be carried over to future billing periods. Please note that switching electric suppliers will cause any accumulated electric supply credits to expire.

Charges or Fees Associated with the Program

For customers under Delivery Service tariffs DS-1 or DS-2 who require no physical alterations to connect to the Ameren Illinois system, there are no upfront charges for metering or connection. Monthly tariff charges do apply to all net electric usage in excess of the amount of electricity generated.
All non-residential customers served under Delivery Service tariffs DS-3 or DS-4 pay the normal charges associated with installing the extraordinary equipment needed to provide dual channel metering.

All applicants are subject to any applicable parallel generator interconnection fees. Please visit our Distributed Generation web page for details on interconnecting parallel generators.

In addition, all installations after Dec. 31, 2013, will be required to be self-installed or installed by a certified installer according to Part 468 Distributed Generation Installer Certification of the Admin Code.
