Ohio's net-metering law requires electric distribution utilities to offer net metering to customers who generate electricity using wind energy, solar energy, biomass, landfill gas, hydropower, fuel cells, or microturbines. Net-metered customers are required to use a single meter capable of recording the flow of electricity in each direction. Under the state's net-metering law, competitive retail electric service (CRES) providers are not required to enter into a net metering contract with a customer. Electric utilities must offer a standard net metering tariff to all requesting customers.
Net-metered systems must meet safety standards specified by the National Electrical Code (NEC), the Institute of Electrical and Electronics Engineers (IEEE), and Underwriters Laboratories (UL). Utilities may not require customer generators to comply with additional safety and performance standards.
System Capacity Limit
There is no specific capacity limit specified. However, a customer generator must size its facility so that it does not exceed 120% of its electricity requirement. The facility must be sized primarily to offset part or all of the customer's electricity requirements.
Net Excess Generation
Credits can be used to offset charges in future months and can be carried forward continuously. Credits for excess generation are calculated based on the energy-only component of the utility's Standard Service Offer and are applied as a monetary credit to the customer's bill. Utilities are not required pay the monetary credit. CRES providers are allowed to offer net-metering contracts to customer-generators at any price, rate, credit, or refund for net excess generation. Customers can choose from multiple net metering offers between various competitive providers. Electric utilities are not allowed to impose charges on the electricity that the customer-generator feeds back to the grid.
Renewable Energy Credits
Renewable Energy Credits (RECs) that are associated with the customer's net metering facility is owned by the customer, unless otherwise contracted with a utility, competitive retail electric service provider, or other entity.
