(Albany, NY) – The Interstate Renewable Energy Council (IREC) today announces its annual assessment of state shared renewables programs through release of its 2019 National Shared Renewables Scorecard.

“IREC’s Scorecard is a one-of-a-kind barometer of program performance, gauging not only the strengths and weaknesses of different programs, but indicating how attractive a program will be to customers,” says IREC VP-Regulatory Sara Baldwin. “The aim of the Scorecard is to help policymakers and regulators understand how to design and lead effective programs that support meaningful and sustainable market growth.”

Shared solar programs – aka community solar programs – continue to grow in popularity as a compelling model to increase access to clean, renewable energy and provide more options for consumers. Seeking to help new states learn from existing programs, IREC’s Scorecard provides an easy reference tool for regulators, policymakers, developers and advocates seeking to better understand how programs stack up, relative to best practices and each other.

The 2019 Scorecard assesses 20 programs in 17 states, and features grades for three newly launched programs in Illinois, New Jersey and Oregon. Three other states not graded on the 2019 Scorecard – California, Connecticut and Maine – have programs still under development and/or awaiting approval.

The Scorecard evaluates only active shared renewables programs – enabled through either legislation or regulatory orders. It does not score voluntary utility-led programs or state programs that are still under development. The details and status of all current state programs are available in IREC’s free Shared Renewables Policy Catalog.

States’ Scorecard grades are determined by specific criteria that reflect how shared renewable energy programs are performing – not just in terms of what policies and rules are in place, but also whether the programs are resulting in projects getting built and customers participating.

Compared to 2018, most states have similar grades for 2019, and still only two state programs, Minnesota and New York, get A’s. The most notable change to the 2019 criteria is the addition of a bonus for programs that have at least 100 MW of installed capacity. This increase from last year’s 10 MW threshold reflects the critical importance of programs being able to scale and spur the development of more meaningful volumes of new renewable energy to serve more customers.

The programs ranked the highest are designed to benefit consumers and expand access to renewable energy through the detailed scoring categories and criteria. These include:

  • General Program Details – including program timeframe, aggregate capacity limit, tracking and reporting requirements, and whether and how the program addresses low- to moderate-income (LMI) consumer participation.
  • Consumers and Subscriptions – including customer eligibility, subscription sizes and terms, and portability and transferability.
  • Generation Systems – including eligible technologies, ownership and management requirements, system capacity limits, minimum and maximum numbers of subscribers per system, and system siting requirements.
  • Bill Credit and Renewable Energy Credits (RECs) – including how the rate is valued, the treatment of unsubscribed energy, and treatment of RECs.
  • Strong Interconnection Procedures – Though interconnection standards are not a part of shared renewable energy program rules, the Scorecard ranks states based on the efficiency, ease and affordability of the interconnection process, which ensures projects are not subject to unnecessary costs and delays.

Although more programs are in place in more states than ever before, the shared renewables market is not yet meeting its full potential. Community solar still represents less than two percent of all operating solar nationwide.

“For states working to achieve ambitious 100% clean energy goals, community solar programs are an important tool that can help ensure clean energy benefits are available to consumers, regardless of income, housing or neighborhood,” says IREC President/CEO Larry Sherwood.

“IREC recognizes that shared renewable energy laws, rules and program design are foundational to a program’s success,” adds Mari Hernandez, IREC regulatory program assistant director. “However, program implementation and other market factors can impact how quickly and effectively programs can scale to meet bigger clean energy policy goals.”

Market development is often impacted by other forces outside of the legislation and rules, such as local permitting and/or land use challenges, the availability of other financial incentives, or other unanticipated issues that arise during implementation. The Scorecard assesses only the rules adopted by a state regulatory commission, and does not reflect these other market forces.

Developers, state officials, utilities, regulators and customers are all still learning how to optimize the shared renewables model to support robust project development, ensure benefits to participants and all ratepayers, and support access to all customers, regardless of a customer’s income or where they live.

“As more states analyze program performance over time, adjustments to all existing programs may be warranted to ensure meaningful, fair and equitable market development,” says IREC’s Baldwin.


A grades (two states): Minnesota and New York. These states have incorporated the majority of identified shared renewables best practices.

B grades (nine states): Colorado, Illinois, Massachusetts (Virtual Net Metering), Maryland, Maine (Net Energy Billing), New Hampshire, New Jersey, Oregon and Washington, D.C. Although these states have some room for improvement, their programs reflect many best practices and offer solid foundations for shared renewable energy development.

C grades (six states): California (Virtual Net Metering), Delaware, Hawaii, Massachusetts (Neighborhood Net Metering), Rhode Island and Vermont. These programs lack the key program components necessary for successful market development.

D grades (two states): California (Enhanced Community Renewables component of Green Tariff Shared Renewables) and Connecticut (both programs – Virtual Net Metering and Shared Clean Energy Facility Pilot Program). These programs do not comport with many of the identified best practices, which could impede program effectiveness and market development.

IREC’s tools and resources – including shared renewables model rules and policy guidelines – help policymakers and stakeholders as they design and implement programs across the country. Like IREC’s National Scorecard, these complementary resources highlight best practices and offer guidance to scale successes more quickly. For states without statewide programs, IREC and Vote Solar’s checklist provides guidance and insights on best practices for voluntary, utility-led community solar programs.
