Note: As of May 2024, utility-specific interconnection rules proposed by Michigan's various investor-owned utilities are currently under review by the Michigan Public Service Commission (MPSC). The new rules must incorporate changes required by Public Act 235 of 2023.

Michigan adopted new statewide interconnection standards, the MIXDG rules, in 2023.

The new interconnection standards use a five-tier system similar to previous rules, but with fast-track processes available for all tiers. The five tiers are:

• Level 1: Certified, 20 kW or less
• Level 2: Certified, 20-150 kW
• Level 3: Not certified, 150 kW or less, or 150-550 kW
• Level 4: 550 kW-

FirstEnergy (formerly GPU) established the Metropolitan Edison Company Sustainable Energy Fund and the Penelec Sustainable Energy Fund in 2000. The Community Foundation for the Alleghenies in Johnstown, Pennsylvania administers the Penelec loan and grant components of the Fund. The fund is administered by the Berks County Community Foundation. The majority of funding available from the fund takes the form of investments made in businesses pursuing one or more of the fund's objectives. These funds typically will be distributed as loans or equity investments, but a limited number of grants are available each year for specific purposes. The following are the

In November 2005, the Indiana Utility Regulatory Commission (IURC) approved rules governing the interconnection of distributed generation (DG). Indiana's interconnection rules require the state's investor-owned utilities to provide three levels of interconnection to customer-generators.

• Level 1: Applies to inverter-based systems with a maximum nameplate capacity of 10 kilowatts (kW). These systems must comply with IEEE 1547 and UL 1741 standards. There are no application fees or other fees for Level 1 interconnection review. Utilities may not impose additional requirements not specified in the IURC rules. There are specific limitations on a single system's potential impact and the aggregate potential impact

FirstEnergy (formerly GPU) established the Metropolitan Edison Company Sustainable Energy Fund in 2000 with an initial contribution of $5.7 million. The fund later received an additional contribution of $2.5 million as a result of the merger between GPU Energy and FirstEnergy, bringing the total to $8.2 million. The fund is administered by the Berks County Community Foundation. The majority of funding available from the Metropolitan Edison Company SEF takes the form of investments made in businesses pursuing one or more of the fund's objectives. These funds typically will be distributed as loans or equity investments. The program is open to

Note: Xcel is not currently accepting proposals for this program. The most recent application deadline was April 1, 2013. See the program web site for information regarding future solicitations.

The Xcel Energy Renewable Development Fund (RDF) was created in 1999 as an outcome of 1994 Minnesota legislation concerning spent nuclear fuel at Xcel Energy’s Prairie Island Nuclear Plant. The original legislation has been amended and added to several times, expanding the amount of money collected by the fund and prescribing funding allocations for specific programs. Funding available for the grant program thus depends on the other funding obligations that

Nevada's Energy Portfolio Standard requires NV Energy to derive or save a minimum percentage of the electricity it sells from renewable energy resources or energy efficiency measures. Included in the standard is a Portfolio Energy Credit (PC) trading program.
Beginning January 1, 2003, Nevada's renewable energy producers can earn PCs, which can then be sold to utilities that are required to meet Nevada's portfolio standard. One PC represents one kilowatt-hour (kWh) of electricity generated, with the exception of the multipliers described below.   Each kWh generated by a photovoltaic (PV) system installed on the premises of a retail customer on

The Arizona Corporation Commission adopted final rules for interconnection of distributed generation facilities in 2020 after a multi-year proceeding. 

There are three levels of review for interconnection applications:

1. Super Fast Track - available for inverter-based generating facilities with a maximum capacity of 20 kW or less which only uses certified equipment

2. Fast Track - available for generating facilities with a maximum capacity of less than 2 MW.

3. Study Track - available for generating facilities of 2 MW or greater or that do not meet the screening requirements for the other tracks.

Additionally, customers seeking interconnection of a

Hawaii has established simplified interconnection rules for small renewables and separate rules for all other distributed generation (DG). For inverter-based systems up to 10 kilowatts (kW) in capacity, there is a simple application process for interconnection. Systems must meet all applicable performance and safety standards from the Institute of Electrical and Electronics Engineers, Underwriters Laboratories, National Electric Code, and where applicable, public utilities commission rules.  For other smaller systems, there are simplified interconnection procedures for net metered systems powered by solar, wind, biomass and hydroelectric up to 50 kW. 

History

Two dockets were opened in 2006 to streamline interconnection procedures

Massachusetts' interconnection standards apply to all forms of distributed generation (DG), including renewables, and all customers of the state's three investor-owned utilities (Unitil, Eversource, and National Grid).

Massachusetts requires investor-owned utilities to have standard interconnection tariffs. There are three basic paths for interconnection in the state:

• The Simplified interconnection process applies to IEEE 1547.1-certified, inverter-based facilities with: 
1. A power rating of 15 kW or less for single-phase systems located on a radial distribution circuit, 
2. A power rating of 25 kW or less for three-phase systems located on a radial distribution circuit (where the aggregated facility capacity is less than 15% of

NOTE: The PSC adopted additional changes in September 2019 through a rulemaking proceeding (Docket R-33929), which include: removing the 0.5% cap on solar users; customers that submit a completed interconnection request and have completed installation by December 31, 2019 are grandfathered for 15 years, and will receive credit at full retail rates; those that do the same but after 2019 will be credited at avoided cost; and any RECs owned by the customer will be retained, and can be transferred upon selling the associated property.
Louisiana enacted legislation in June 2003 establishing net metering.
