In October 2008, New Jersey enacted legislation exempting renewable energy systems used to meet on-site electricity, heating, cooling, or general energy needs from local property taxes. (There is not a state component to property taxes in New Jersey). Eligible renewable energy systems* include solar PV, wind, fuel cells, sustainable biomass, geothermal electric, landfill gas, hydroelectric, resource recovery, wave, and tidal systems that produce electricity. Systems that produce energy from solar thermal energy (e.g., solar hot water) or geothermal energy (e.g., geothermal heat pumps) are also eligible for the exemption. The exemption may be claimed for all qualified systems installed on

Note: The Tax Cuts and Jobs Act (HR 1) of 2017 repealed the use of tax credit bonds effective January 1, 2018.  Issuers of QECBs that elected to receive direct payments from the Treasury issued on or before December 31, 2017, consistent with the Internal Revenue Code (Section 54D), will continue to receive direct payments. The summary presented below is for historical purposes. 

The Energy Improvement and Extension Act of 2008, enacted in October 2008, authorized the issuance of Qualified Energy Conservation Bonds (QECBs) that may be used by state, local and tribal governments to finance certain types of

Michigan enacted Public Act 235 in November 2023, expanding renewable energy requirements substantially and adding a clean energy standard. Renewable energy requirements are now 50% by 2030 and 60% by 2035. Clean energy requirements are 80% by 2035 and 100% by 2040.

In October 2008, Michigan enacted the Clean, Renewable, and Efficient Energy Act (Public Act 295), requiring the state's investor-owned utilities, alternative retail suppliers, electric cooperatives, and municipal electric utilities to generate 10% of their retail electricity sales from renewable energy resources by 2015. SB 438, signed in December 2016, increased this requirement to 15% by 2021, and

Note: In December 2016, the Arizona Corporation Commission (ACC) voted to replace net metering with "net billing", where new customer-generators will be credited at an avoided cost rate for energy exported to the grid. Although this entry is categorized as net metering, the policy adopted by the ACC does not meet DSIRE's definition of net metering, as excess generation will no longer be netted one-to-one against consumption over the billing period.

Eligibility and Availability

Net billing is available to investor-owned utility and electric cooperative customers who generate electricity using solar, wind, hydroelectric, geothermal, biomass, biogas, combined heat and power, or

Oncor provides incentives to service providers and self-sponsors who install eligible energy efficiency measures at facilities serviced by Oncor through their Commercial Standard Offer Program (CSOP). Independent companies/contractors are eligible to participate. The program is divided into deemed projects and measurement & verification projects. Deemed projects offer incentives to service providers who complete projects with deemed kilowatt and kilowatt-hour savings. Measurement & verification (M&V) projects offer incentives to service providers and self-sponsors who complete measures requiring measurement and verification. Oncor will pay service providers a fixed price per kilowatt and kilowatt-hour saved based on the estimate of useful life of

The original enabling legislation in 2008 ended the program after five years. In 2012, H.B. 250 extended the program an additional 10 years through June 2023. In 2023, H.B. 62 extended the life of this program in perpetuity, removing the sunset date of June 2023.

In 2024, S.B. 187 approved $10.5 million for five projects under Round 16 (FY 2025). Through FY 2025, the legislature has authorized over $328 million in grants across 924 grants.

In May 2008, Alaska enacted legislation authorizing the creation of the Alaska Renewable Energy Fund, a grant fund administered by the Alaska Energy Authority (AEA)

Note: The Inflation Reduction Act (H.R. 5376) made several changes to this program. It appropriated approximately $11.7 billion in total for the Loan Programs Office (LPO) to support issuing new loans. This, in turn, increased the loan authority in LPO’s existing loan programs by approximately $100 billion. The Inflation Reduction Act also adds a new loan program, the Energy Infrastructure Reinvestment (EIR) Program (section 1706), to help retool, repower, repurpose, or replace energy infrastructure that has ceased operations or to improve the efficiency of infrastructure that is currently operating.

In July 2008 Missouri enacted legislation allowing homeowners to take an income tax deduction of the cost of home energy audits and associated energy efficiency improvements. The tax deduction is valid for expenses incurred on or after January 1, 2009. Any deduction shall be claimed for the tax year in which the qualified home energy audit was conducted or in which the implementation of the recommended energy efficiency improvements occurred.

The deduction claimed cannot exceed $1,000 per year for individual taxpayers or exceed $2,000 per year for taxpayers filing combined returns. A taxpayer may not take a deduction for work that
