Local Option - Sales and Use Tax Exemption for Renewable Energy Systems

Note: See the supplemental Sales & Use Tax Topics: Renewable Energy Components Form for more information.

Colorado enacted S.B. 07-145 in April 2007, authorizing counties and municipalities to offer property or sales tax rebates or credits to residential and commercial property owners who install renewable energy systems on their property. 

Eligible renewable energy property is defined as "any fixture, product, system, device or interacting group of devices that produce electricity from renewable resources, including, but not limited to, photovoltaic systems, solar thermal systems, small wind systems, biomass systems, or geothermal systems."

The incentive is administered at the local level by

Green Building Requirement

Effective Sept. 21, 2022, DC has adopted the Clean Energy DC Building Code Amendment Act of 2022 (D.C. Law 24-177) which calls for the District to adopt an NZE building code that applies to the new construction or substantial improvement of any building subject to the Commercial Provisions of the DC Energy Conservation Code, including commercial buildings and residential buildings taller than 3 stories. Regulations for this law must be finalized by the Mayor by December 31, 2026.

Currently the District has a voluntary Net Zero Building Code that will serve as the basis for the Net-Zero-Energy standard

Renewable Energy Standard

In 2007, Minnesota legislation modified the state's 2001 voluntary renewable energy objective to create a mandatory renewable portfolio standard (RPS). Public utilities (i.e., investor-owned utilities), generation and transmission electric cooperatives, municipal power agencies, and power districts operating in the state are required to have at least 25% of retail electricity sales be generated or procured using eligible renewable sources by 2025, with a higher standard for Minnesota's nuclear utility, Xcel Energy. 

In 2013, H.F. 729 created an additional requirement that all public utilities have 1.5% of retail electricity sales be generated or procured using solar energy by 2020 and set

Renewable Energy Property Tax Assessment

Locally Assessed Renewable Energy Property

Solar photovoltaic (PV), including agrivoltaics and floatovoltaics, and wind energy facilities with a capacity of 2 megawatts (MW) AC or less are assessed locally for property taxes. Additionally, low impact hydro, geothermal, and biomass facilities with a capacity of 2 MW or less and which were placed in service prior to January 1, 2010, are also assessed locally for property taxes. In assigning value to renewable energy property, local assessors are required to use the cost approach outlined in the Assessors' Reference Library. Assessors must also examine the sales comparison and income approaches, both described in

Net Metering

Note: HB 2201 of 2015 requires the Public Utility Commission to investigate and adopt new net metering and interconnection rules. The bill prohibits cross-subsidization of ratepayers potentially caused by net metering tariffs and limits IOUs from allowing more than 3% of aggregate load to be generated by solar power. The Commission opened a new proceeding (GO 258.3) in September 2018 to investigate the state's net metering rules. The summary below describes the current net metering rules.

Interconnection Guidelines

The South Carolina Public Service Commission (PSC) adopted simplified interconnection guidelines for small distributed generation (DG) in December 2006.  South Carolina's interconnection guidelines apply to Duke Energy Progress, Duke Energy Carolinas, and Dominion Energy. These guidelines address interconnection of renewable- energy systems and other forms of DG in three levels -

  1. Streamlined interconnection process for a certified inverter based generating unit up to 20 kW
  2. Fast Track for interconnection for systems larger than 20 kW up to 2 MW
  3. For larger interconnection systems greater than 2 MW requiring interconnection study.

Renewable Energy Standard

With the passage of Initiative 937 in 2006, Washington became the second state after Colorado to pass a renewable energy standard by ballot initiative. Initiative 937, which was enacted as the Energy Independence Act (EIA), calls for electric utilities that serve more than 25,000 customers in the state of Washington to obtain 15% of their electricity from new renewable resources by 2020 and to undertake all cost-effective energy conservation. Investor-owned utilities, municipal utilities, rural electric cooperatives, and public utility districts are subject to this standard.* Of Washington's 62 utilities, 18 are considered qualifying utilities, representing about 80% of Washington's load

Avista Utilities - Net Metering

Idaho does not have a statewide net-metering policy. However, each of the state's three investor-owned utilities -- Avista Utilities, Idaho Power and Rocky Mountain Power -- has developed a net-metering tariff that has been approved by the Idaho Public Utilities Commission (PUC). The framework of the utilities' net-metering programs is similar, in that each utility's original program: (1) offers net metering to customers that generate electricity using solar, wind, hydropower, biomass or fuel cells; (2) limits individual system size to 100 kilowatts (kW); (3) limits aggregate net-metered capacity to 0.1% of the utility's peak demand in a baseline year (1996

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
