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.
New Hampshire requires all utilities selling electricity in the state to offer net metering to customers who own or operate systems up to one megawatt (1 MW) in capacity that generate electricity using solar, wind, geothermal, hydro, tidal, wave, biomass, landfill gas, bio-oil or biodiesel. CHP systems that use natural gas, wood pellets, hydrogen, propane or heating oil are also eligible.* The aggregate statewide capacity limit of all net-metered systems is 50 MW.
In March 2008, the Florida Public Service Commission (PSC) adopted interconnection rules 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.
Florida's interconnection rules include provisions for three tiers of renewable-energy systems:
* Tier 1: 10 kilowatts (kW) or less
* Tier 2: Larger than 10 kW, but not larger than 100 kW
* Tier 3: Larger than 100 kW, but not larger than 2 MW
Tennessee offers a special ad valorem property tax assessment for certified green energy production facilities. Property that generates electricity from a certified facility shall be assessed as follows:
