Customer-generators who applied for net metering prior to January 1, 2022 may remain on a prior tariff for a period of time: December 31, 2025 for customers who applied for net metering before May 16, 2019, and May 31, 2029 for customer-generators who applied for net metering between May 16

The Public Regulation Commission (PRC) adopted revised standards and procedures for the interconnection of generating facilities in New Mexico in July 2008.

Rule 569 applies to all qualifying facilities (QFs) under the federal Public Utility Regulatory Policies Act, which generally includes all renewable energy systems and combined heat and power (CHP) systems up to 80 megawatts (MW) in capacity.

Rule 568 applies to renewable energy systems and CHP systems up to 10 MW in capacity. The purpose of Rule 568 is to simplify the interconnection requirements for QFs up to 10 MW and to encourage the use of small-scale, customer-owned

In August 2008, the State of New York enacted legislation allowing a property tax abatement for photovoltaic (PV) system expenditures made on buildings located in cities with a population of 1 million or more people. This limits the abatement to systems installed within New York City. Eligible buildings include all real property except utility real property. As originally enacted, the in-service deadline for eligible systems was December 31, 2012. However, in August 2012 the abatement was extended to systems placed in service through December 31, 2014, at a reduced rate. In September 2014, S.B. 746 extended the compliance period for

In August 2008, North Carolina enacted legislation that exempts 80% of the appraised value of a "solar energy electric system" (also known as a photovoltaic, or PV, system) from property tax. For the purposes of this assessment, the term "solar energy electric system" means "all equipment used directly and exclusively for the conversion of solar energy to electricity." This incentive is effective for taxable years beginning on or after July 1, 2008.

A Memorandum sent to County Commissioners in February 2011 clarified that residential PV systems that are not used to generate income or in connection with a business may

The New Jersey Office of Clean Energy (OCE) offers rebates to state residents who purchase certain energy efficient home appliances. The program website has a search engine where consumers can look up if their product is eligible for rebate. The OCE also offers a $50 rebate for refrigerator/freezer recycling. This recycling offer is only valid till June 30, 2017.

In May 2013, Oklahoma enacted H.B. 1990, repealing the high-performance building certification program.

The State is still required by statute to adopt planning and construction standards for state buildings that conserve energy and optimize the energy performance of new buildings. The standards must reduce dependence on imported sources of energy through energy efficiency and local and renewable energy sources.

The standards must also authorize the Office of Management and Enterprise Services to pursue ENERGY STAR designation to demonstrate energy efficiency in public buildings. 

National Grid offers a variety of energy efficiency incentives for residential customers. Incentives are provided for purchasing and implementing insulation upgrades, HVAC equipment, appliances, pool pumps, lighting fixtures, and other measures.
