Zero-Emission Facilities Production Tax Credit

Note: Systems entering service on or after January 1, 2021 cannot qualify for this credit. The credit will no longer be available for all systems beginning in 2022.

For tax years beginning on or after January 1, 2003 and before December 31, 2021, a state income tax credit is available to producers of electric power using renewable energy resources from a zero-emission facility located in Oklahoma. The zero-emission facility must have a rated production capacity of 1 megawatt or greater. The facility must be placed in operation after June 4, 2001, and the electricity must be sold to an unrelated

Interconnection Standards

In July 2010, the Montana Public Service Commission (PSC) adopted interconnection rules, effective August 13, 2010. These rules apply to all electric utilities under the PSC's jurisdiction, including investor-owned utilities and co-ops. Small generators, or systems for the production and or storage of electricity with a nameplate capacity up to 10 megawatts (MW), located on the land of utility customers within good standing are allowed to interconnect. While there is no statewide standard interconnection agreement, the largest investor-owned utility in Montana, NorthWestern, does have a standard interconnection agreement for net-metered systems. The use of certain equipment may qualify a facility

Renewable Portfolio Standard

Hawaii's Renewable Portfolio Standard (RPS) requires each electric utility company that sells electricity for consumption in Hawaii to have the following percentages of electricity sales come from renewable energy by the corresponding date. H.B. 2089 of 2022 amended the RPS to be based on net electricity generation rather than retail sales beginning in compliance year 2030. 

  • 10% of its net electricity sales by December 31, 2010;
  • 15% of its net electricity sales by December 31, 2015;

Alternative Energy Revolving Loan Program

The Alternative Energy Revolving Loan Program (AERLP) provides loans to individuals, small businesses, local government agencies, units of the university system, and nonprofit organizations to install alternative energy systems that generate energy for their own use. Funding may be used to provide loans for construction of alternative energy systems and capital investments for energy conservation purposes when done in conjunction with an alternative energy system. The program is funded by air quality penalties collected by the Department of Environmental Quality (DEQ). The program is administered by DEQ, which is responsible for developing the rules.

Alternative energy systems are defined by

Smart Renewable Energy Tariffs

Note: The Hawaii Public Utilities Commission (PUC) issued a decision and order in December 2023 adopting  two new permanent Smart DER tariff options (Smart Renewable Energy Export and Smart Renewable Energy Non-Export), which took effect on April 1, 2024. Customers taking service under one of the previous tariffs will be transitioned to the Smart Renewable Energy Export program after seven years in their current program. The earliest transitions will begin on October 1, 2024. The summary below describes the new Smart DER tariffs, followed by the previous interim tariff options.

Renewable Portfolio Standard

Note: Public Act 102-0662, the Climate and Equitable Jobs Act (CEJA), enacted in September 2021, increased the RPS to require 50% renewable energy by 2040. This law also says that it is the policy of the state to rapidly transition to 100% clean energy by 2050.

Under CEJA, the 25% target by 2025 remains in place, and will increase by at least 3% each year from 2025 to 2030 until reaching 40% in 2030. Thereafter, the Illinois Power Agency will determine the specific increase each year, attempting to procure 50% by delivery year 2040, taking into account energy demand, other

Renewable Energy Sales and Use Tax Exemption

In Washington State, there are sales tax exemptions for the sale of equipment used to generate electricity, as well as for the sale of "hog fuel," defined as wood waste and other wood residuals including forest-derived biomass. It does not include firewood or wood pellets. Hog fuel must be used to produce electricity, steam, heat, or biofuel. Hog fuel is fully exempt from sales tax, though the buyer must provide the seller a completed sales tax exemption certificate and must complete an annual tax incentive survey. The exemption was originally set to expire June 30, 2024, but was extended to

Net Metering

Note: A decision filed by the Georgia Public Service Commission in Georgia Power's 2019 rate case required Georgia Power to offer net metering with monthly netting to 5,000 rooftop solar customers or 32 MW of capacity, whichever comes first. This cap was met in 2021. The PSC made a decision in Georgia Power's 2022 rate case that kept the cap, and stipulated that for current and new customers on instantaneous net metering, Georgia Power will pay an avoided cost in addition to four cents/kWh for excess generation starting January 1, 2023 -- with the additional amount set in place until a

Pasadena Water and Power - Solar Power Installation Rebate

Pasadena Water & Power (PWP) offers its electric customers a rebate for photovoltaic (PV) installations, with a goal of helping to fund the installation of 14 megawatts (MW) of solar power by 2017. The rebate amount varies depending on the customer class installing the system and the system's size. Systems up to 30 kilowatts (kW) are eligible for the Expected Performance Based Buydown (EPBB) or can opt for the performance based incentive (PBI). The EPBB provides a one-time lump sum payment after installation and inspection approval based on the system's estimated AC energy output. The energy output is estimated using
