This bill directs the California Public Utilities Commission to adopt or modify customer renewable energy subscription programs (community renewable energy or “community solar” style programs) under a single, consistent framework. It establishes program goals — efficient service to distinct customer groups, reduced duplication, and increased participation by low‑income customers — and sets program design constraints and targets that the CPUC must incorporate.
The statute ties program economics to avoided‑cost crediting, requires paired storage and local siting, imposes project labor and prevailing‑wage rules (with a project labor agreement alternative), and caps both individual project size and total program capacity or duration. Those design choices will shape who can build projects, how subscribers benefit, and whether projects can capture time‑limited federal incentives.
At a Glance
What It Does
It requires the CPUC to create a customer renewable energy subscription program with binding design rules: credits based on avoided‑cost values, a requirement that at least 51% of enrolled capacity serve low‑income customers, storage paired with solar at four hours minimum, per‑project caps of 5 MW, and either a 4 GW program cap or a seven‑year program sunset.
Who It Affects
Community Choice Aggregators (CCAs), electric service providers, distributed generation developers, and residential subscribers — especially low‑income and disadvantaged community residents — face the new program rules and notification obligations. The Energy Commission and Labor Commissioner also gain evaluation and enforcement roles.
Why It Matters
The bill attempts to standardize community solar offerings across utilities and CCAs while prioritizing equity and local reliability. Its mix of labor, storage, siting, and crediting rules could unlock federal tax benefits for qualifying projects but also raise development costs and change which business models are viable.

What This Bill Actually Does
The bill creates a single legal framework for customer renewable energy subscription programs — programs that let customers subscribe to generation located offsite (commonly called community solar or shared renewables). It starts by defining eligible participants, low‑income and underserved communities, and the types of programs that fall inside or outside the new rules (excluding existing net energy metering and the Multifamily Affordable Housing Solar Roofs Program).
The CPUC must evaluate current programs and then adopt or modify a program that meets the statute’s goals.
Substantive design requirements shape both project economics and siting. The statute ties subscriber bill credits to a full avoided‑cost calculation that includes long‑run values for energy, ancillary services, greenhouse‑gas reductions, high‑GWP gases, and transmission and distribution capacity; it allows the CPUC to use actual wholesale prices for the energy portion.
The law bars program costs from being charged to nonparticipating customers in excess of those avoided costs, while permitting nonratepayer funds to provide incentives beyond avoided costs. It also prioritizes making projects eligible for an enhanced federal investment tax credit for low‑income benefits.On the supply side, all solar facilities in the program must be paired with energy storage that supplies at least four hours at the solar capacity.
Each facility is limited to 5 megawatts of generation and 5 megawatts of storage. Projects must be sited in the same local reliability area as their subscribers unless the CPUC later modifies that requirement.
The bill caps the overall program at 4 gigawatts or ends it after seven years — whichever occurs first — and requires quarterly, project‑level public reporting during the program’s first two years.Labor and enforcement provisions are explicit. Construction workers on program projects must be paid prevailing wages and contractors must keep payroll records; the Labor Commissioner may enforce prevailing‑wage obligations.
The bill provides an alternative path: a project labor agreement that contains its own prevailing‑wage protections and arbitration enforcement can substitute for the standard prevailing‑wage enforcement regime. Finally, the Energy Commission must evaluate whether community solar plus storage can be treated as a load‑modifying resource for resource adequacy purposes, which would reduce procurement obligations for load‑serving entities if the Commission so determines.
The Five Things You Need to Know
The program must reserve at least 51% of its capacity for low‑income customers.
Each participating solar facility must be paired with storage that provides at least four hours of capacity at the same rating as the solar generator.
Individual projects are limited to 5 MW generation and 5 MW storage; total program capacity is capped at 4 GW or terminated after seven years, whichever comes first.
Subscriber bill credits must be calculated using the commission’s avoided‑cost framework and include long‑run values for energy, ancillary services, greenhouse‑gas reductions, and transmission and distribution capacity.
Construction workers on program projects must receive prevailing wages, unless the project operates under a qualifying project labor agreement that enforces prevailing wages through arbitration.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definitions and program scope
This initial subsection defines terms that determine who and what the statute covers: affordable housing, community choice aggregators, eligible customer‑generators, low‑income and underserved communities, local reliability areas, and what counts as a customer renewable energy subscription program (explicitly excluding NEM and the Multifamily Affordable Housing Solar Roofs Program). Those definitions control eligibility for the program’s low‑income prioritization, siting constraints, and which existing offerings must be evaluated or terminated.
Evaluation of existing programs and termination authority
The CPUC must evaluate current customer subscription programs (including the Green Tariff Shared Renewables Program and any disadvantaged‑community alternatives) against three statutory goals: serve distinct customer groups efficiently, avoid duplicative offerings, and promote robust low‑income participation. If a program fails those goals, the CPUC may terminate or modify it. This gives the commission affirmative authority to streamline overlapping offerings and to wind down legacy programs that do not meet the equity test.
Adoption, participation notice, and administrative timing
The statute requires the CPUC to adopt or modify a program in a new proceeding and obliges CCAs and electric service providers to notify the commission within 180 days whether they will participate; they can later enter or exit the program by notifying the CPUC. That notification scheme centralizes participation decisions with the regulator and creates a single point of record for which load‑serving entities are offering subscription products.
Crediting, incentives, and low‑income prioritization
This block sets the financial rules. Subscriber bill credits must be based on avoided‑cost calculations that capture a full range of long‑run values (energy, capacity, transmission and distribution, ancillary services, GHG benefits and more). The law bars charging nonparticipants more than the calculated avoided costs, but allows nonratepayer funds to top up credits. It requires that at least 51% of program capacity serve low‑income customers and calls for prioritizing state and federal incentives — specifically structuring projects to qualify for an enhanced federal investment tax credit for low‑income economic benefit projects.
Labor standards, technical and size constraints, and reporting
Construction workers must receive prevailing wages, payroll records must be maintained, and the Labor Commissioner has enforcement authority; alternatively, a qualifying project labor agreement can satisfy labor requirements. Technically, solar projects must be paired with storage providing four hours of capacity and be sited within the same local reliability area as subscribers (unless the CPUC relaxes that rule). Individual projects cannot exceed 5 MW of generation or 5 MW of storage. The statute caps the entire program at 4 GW or seven years and mandates project‑level quarterly reporting for the first two years, including subscriber participation and local hiring details.
Energy Commission resource adequacy evaluation
The Energy Commission must evaluate whether community solar plus storage should be treated as a load‑modifying resource for resource adequacy obligations and issue a determination. If deemed a load‑modifying resource, these projects could reduce the resource adequacy procurement obligations for load‑serving entities. The CPUC will also re‑evaluate the program two years after adoption and may terminate or modify it if it no longer meets statutory requirements.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Low‑income households and residents of underserved communities — receive prioritized access to subscriptions (at least 51% of capacity) and programs structured to capture enhanced federal tax incentives aimed at low‑income benefits.
- Subscribers in transmission‑constrained local reliability areas — gain nearby generation and paired storage designed to address local capacity needs and reduce exposure to transmission constraints.
- Local workers and labor organizations — benefit from prevailing‑wage requirements and payroll transparency, and from opportunities tied to local hiring reports and enforcement mechanisms.
- Developers able to meet the statute’s technical and labor standards — can compete for projects that may qualify for enhanced federal investment tax credits and access a regulated market for subscriber uptake.
Who Bears the Cost
- Distributed generation developers with tight margins — face higher upfront costs from paired storage, prevailing wages or project labor agreements, and the 5 MW size limit that may disfavor economies of scale.
- Nonparticipating ratepayers — while the bill caps charges to nonparticipants at avoided costs, changes to avoided‑cost methodologies or miscalculation risks could still shift costs or benefits across customer classes.
- Community choice aggregators and electric service providers — must administratively decide whether to participate, track subscriptions, and report; they may also face integration and billing complexity.
- State agencies and regulators (CPUC, Energy Commission, Labor Commissioner) — take on evaluation, reporting, enforcement, and analytical workloads tied to avoided‑cost calculations, RA determinations, and quarterly public reporting requirements.
Key Issues
The Core Tension
The central dilemma is between directing the lion’s share of program capacity to low‑income and disadvantaged customers (equity) and imposing technical, labor, and siting rules that increase development costs and reduce scale (viability): the law guarantees equitable intent but may make projects harder to finance and build, potentially undermining the very access it seeks to expand.
The bill stacks several policy priorities — equity, local reliability, labor standards, storage integration, and federal tax‑credit optimization — into a single program design. Those priorities interact in ways that can pull project economics in opposite directions: requiring storage and prevailing wages raises costs that the statute attempts to offset by declaring broad avoided‑cost values and by encouraging the use of federal incentives, but whether those offsets sufficiently restore developer returns is uncertain.
The 5 MW project cap and local‑siting requirement further limit portfolio scale and geographic pooling, which increases per‑kilowatt costs and complicates financing compared with larger distributed portfolios.
Operationally, the avoided‑cost crediting mandate adds complexity. Crediting must include long‑run values across energy, capacity, ancillary services, transmission and distribution, and greenhouse‑gas benefits — categories that are difficult to quantify and are subject to evolving regulatory methodologies.
The bill also forbids charging nonparticipants more than avoided costs while permitting nonratepayer top‑ups, which raises questions about who will supply those top‑ups, how they will be administered, and whether reliance on temporary federal incentives will create a cliff that undermines project pipelines. Finally, the public quarterly reporting requirement that includes subscriber information improves transparency but raises privacy and commercial confidentiality concerns that the CPUC will need to manage.
