The Indiana Utility Regulatory Commission (IURC) adopted rules for net metering in September 2004, requiring the state's investor-owned utilities (IOUs) to offer net metering to all electric customers. The rules, which apply to renewable energy resource projects [defined by IC 8-1-37-4(a)(1) - (8)] with a maximum capacity of 1 megawatt (MW), include the following provisions:
In March 2008, the Florida Public Service Commission (PSC) adopted rules for net metering and interconnection for renewable-energy systems up to two megawatts (MW) in capacity. The PSC rules apply only to the state's investor-owned utilities; the rules do not apply to electric cooperatives or municipal utilities. Net metering is available to customers who generate electricity using solar energy, geothermal energy, wind energy, biomass energy, ocean energy, hydrogen, waste heat or hydroelectric power.
Net metering is available to customers who generate electricity using solar, wind, hydroelectric, geothermal, biomass, biogas, combined heat and power (CHP) or fuel cell technologies. The ACC has not set a firm kilowatt-based limit on system size capacity; instead, systems must be sized to not exceed 125% of the customer’s total connected load. If there is no available load data for the customer, the generating system may not exceed the customer’s electric service drop capacity.
The Commonwealth of the Northern Mariana Islands enacted its Renewables Portfolio Standard in September 2007, in which a certain percentage of its net electricity sales must come from renewable energy. Under the law, the Commonwealth Utilities Corporation (the Islands' only and semi-autonomous public utility provider) must meet the following benchmarks:
* 10% of net electricity sales by December 31, 2008
* 20% of net electricity sales by December 31, 2010
* 40% of net electricity sales by December 31, 2012
* 80% of net electricity sales by December 31, 2014

North Carolina enacted legislation ([http://www.ncleg.net/Sessions/2009/Bills/House/PDF/H1389v7.pdf H.B. 1389]) in August 2009 that authorizes cities and counties to establish revolving loan programs to finance renewable energy and energy efficiency projects that are permanently affixed to residential, commercial or other real property. A revolving loan program generally refers to a loan fund, where the loan repayments and interest are fed back into the fund.
Several provisions of Missouri law govern energy efficiency in state facilities. In 1993 Missouri enacted legislation requiring life-cycle cost analysis for all new construction of state buildings and substantial renovations of existing state buildings when major energy systems are involved. Substantial renovations involve projects that will affect at least 50% of the building's square footage or cost at least 50% of its market value.
Utah requires the state's only investor-owned utility, Rocky Mountain Power (RMP), and most electric cooperatives* to offer net metering to customers who generate electricity using solar energy, wind energy, hydropower, hydrogen, biomass, landfill gas, geothermal energy, waste gas or waste heat capture and recovery. The bill that established net metering also established some basic rules for interconnection. In April 2010, the Utah Public Service Commission (PSC) adopted final rules for interconnection. The rules described below took effect April 30, 2010.
