Net Metering Statutes – Net metering allows electric utility customers to install grid-connected renewable energy systems on their property and get credit for the amount of excess electricity the systems produce. Thirty-five States and the District of Columbia had State-wide net metering statutes in 2004. EPACT 2005 requires electric utilities, nationwide, to offer their customers net metering service upon request by 2008.
