Commonwealth's Energy Leasing Program

Lease financing administered by the Department of Treasury provides funding for energy efficiency projects in state facilities operated by state agencies, authorities and institutions of the Commonwealth of Virginia. The Energy Leasing Program allows for the purchase of services and equipment required to develop, design, and install an energy efficiency project. Agencies can finance energy projects at a minimum of $100,000 and will make repayments over 12 or 15 year terms.

The funds can be used to finance projects with relevant energy efficient technology, such as lighting and motor efficiency upgrades, building envelope enhancements, distribution system improvements, and energy management

Advanced Energy Fund


The Advanced Energy Fund is a public benefit fund administered by the Ohio Development Services Agency. The Advanced Energy Fund supplies funds for the Advanced Energy Fund Grant program. Advanced Energy Loan fund assets are also used to fill other actively lending funds such as the Energy Loan Fund. Energize Ohio is a compilation of state programs that works to promote energy incentives, find programs to meet your needs at their site. 

Ohio's Advanced Energy Fund was originally authorized by the state's 1999 electric restructuring legislation. The Fund supports the Advanced Energy Program, which at different times has provided

Clean Energy Development Fund

Vermont's Clean Energy Development Fund (CEDF) was established in 2005 to promote the development and deployment of cost-effective and environmentally sustainable electric power and thermal resources -- primarily renewable energy and combined heat and power (CHP) technologies.

Funding Sources

From its establishment to 2012, the CEDF was supported via annual payments from Entergy (which owns the Vermont Yankee nuclear power plant). In return, under terms of two memoranda of understanding between Entergy and the Vermont Department of Public Service (DPS) that expired in March 2012, Entergy was permitted to store its own spent nuclear fuel at the Vermont Yankee site

Energy Equipment Property Tax Exemption

Arizona’s property tax exemption was established in June 2006 (H.B. 2429) and originally applied only to “solar energy devices and any other device or system designed for the production of solar energy for on-site consumption.” For property tax assessment purposes, these devices are considered to add no value to the property.

A "solar energy device" for the purpose of this incentive is defined as "a system or series of mechanisms designed primarily to provide heating, to provide cooling, to produce electrical power, to produce mechanical power, to provide solar daylighting or to provide any combination of the foregoing

Renewable Energy Competitive Incentive Program

Wisconsin Focus on Energy offers a competitive grant to support the deployment of large renewable energy projects. The Renewable Energy Competitive Incentive Program (RECIP) provides incentives for cost-effective renewable energy systems installed at eligible Wisconsin organizations through a competitive request for proposals (RFP) process that occurs twice per year. Grant recipients and projects must be located in a participating electric or gas utility's service territory (see here for participating utilities).

A project’s incentive amount is determined based on the estimated first year net energy production (or offset) of the system. Applicants must propose a $/kWh and/or $/Therm amount

Green Power Purchasing

Note: The green power purchasing goal has a target date of 2011. As of August 2021, the state has not created new green power purchasing targets. 

Pursuant to S.B. 459 enacted in March 2006, Wisconsin's Departments of Administration, Corrections, Health and Family Services, Public Instruction, Veterans Affairs, and the Board of Regents of the University of Wisconsin System have a goal of purchasing or generating 10% of their power from renewable energy by December 31, 2007, and 20% by December 31, 2011. In July 2008 the Governor announced that the state had completed a green electricity purchase of 92,400 megawatt-hours

Interconnection Standards

In December 2005 the Colorado Public Utilities Commission (PUC) adopted standards for net metering and interconnection, as required by Amendment 37, a renewable energy ballot initiative approved by Colorado voters in November 2004. The interconnection rules were overhauled in July 2021.

The PUC standards generally apply to investor-owned utilities (IOUs) with 40,000 or more customers and all electric cooperatives. Municipal utilities with 5,000 customers or more are required to adopt interconnection rules that are functionally similar to the PUC's standards (see H.B. 08-1160). Electric cooperatives and municipal utilities may reduce or waive any insurance requirements that apply to IOUs.

California Solar Rights Act

The Solar Rights Act (CA Civil Code 714), enacted in 1978, bars restrictions by homeowners associations (HOAs) on the installation of solar-energy systems, but originally did not specifically apply to cities, counties, municipalities or other public entities. Subsequent legislation extended these restrictions to all public entities and common interest developments.  These entities are allowed to impose reasonable restrictions on a solar energy system that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance. 

"Significantly" was not originally defined, but later legislation adopted a specific dollar amount and system efficiency impact that the

Renewables Portfolio Standard

Note: S.B. 33, enacted in February 2021, increased and extended the RPS. 

In 2005, S.B. 74 established a renewables portfolio standard (RPS) requiring retail electricity supplier to purchase 10% of the electricity sold in the state from renewable sources by compliance year (CY) 2019-2020.  S.B. 119 of 2010 increased the RPS to 25% by CY 2025-2026. The RPS was extended again by S.B. 33 of 2021. The RPS applies to the state's investor-owned utilities, retail electric suppliers, municipal utilities, and rural electric cooperatives. Municipal utilities and rural electric cooperatives are allowed to opt out of the RPS requirement if
