KYPublic Service Commission
Under Kentucky law, "net metering" is defined as “measuring the difference between the electricity supplied by the electric grid and the electricity generated by an eligible customer-generator that is fed back to the electric grid over a billing period.” Net metering allows customers who use power sources such as solar cells or small windmills to send any excess power back to their electric utilities and receive a credit against their electric bills. Such net metering, which already applied to solar power sources in Kentucky, was expanded by the Kentucky General Assembly in 2008 to include small generators of wind energy, hydroelectric power, and power from biomass or bio-gas.
In addition to expanding the types of electric generation eligible for net metering, the 2008 law also doubled the maximum capacity of such generators from 15 kilowatts to 30 kilowatts, raised the limit on the amount of generation allowed on a single utility’s system, and extended the life of net metering credits to the life of a customer account. The 2008 law also required the Public Service Commission to develop interconnection and net metering guidelines for all retail electric suppliers operating in Kentucky. Those guidelines were issued by the Commission on January 8, 2009, and are posted below in .pdf format.
