Progress Around the Edges: Unpacking California’s 2026 Climate Legislation
California’s climate ambitions have long been defined by sweeping targets: achieving statewide carbon neutrality by 2045, installing six million electric heat pumps in homes, and mandating a total phaseout of new gas-powered cars. However, as Governor Gavin Newsom’s second term draws to a close, the challenges of implementation are becoming increasingly difficult to separate from the state’s broader climate agendas. Rising electricity costs complicate the economics of electrifying homes, businesses, and vehicles, while wildfire risks, aging infrastructure, and fragmented public programs add pressure to an already complex energy system.
The 2025-2026 legislative session offers a revealing snapshot of how California is navigating these trade-offs. California lawmakers have pivoted away from large state spending and top-down consumer mandates, focusing instead on reining in monopoly utilities and streamlining bureaucratic processes like permitting. Governor Newsom’s signatures and vetoes shaped the final legislative package, reflecting his competing priorities around consumer protection, administrative feasibility, fiscal constraints, and climate action.
While the passage of these bills represents meaningful progress, these policy shifts are not yet commensurate with the scale of the challenge. Incremental reforms like scrutinizing utility spending, increasing infrastructure transparency, and streamlining project approvals are important – but are they sufficient for the coordinated transformation that California’s climate goals ultimately demand?
Utility Oversight
High utility bills remain a central political issue in Sacramento. Several measures adopted during the 2025-2026 legislative session sought to strengthen oversight of investor-owned-utilities (IOUs), scrutinize recoverable costs, and improve accountability for infrastructure spending.
Assembly Bill 2463 targets the financial core of utility earnings by directing the California Public Utilities Commission (CPUC) to overhaul Return on Equity calculations, creating a strict performance-and-risk framework that prevents utilities from pocketing inflated profit margins on routine construction projects.
Lawmakers also moved to close accounting loopholes that utilities use to raise rates behind closed doors. Senate Bill 1098 mandates that utility “balancing accounts”, financial holding accounts where utilities bank unreviewed cost overruns to collect from customers later, must be integrated directly into primary General Rate Cases for public regulatory scrutiny before those charges can appear on monthly utility bills.
To protect residential neighborhoods from paying for the tech sector’s growing power demand, Senate Bill 1168 and Assembly Bill 2383 establish rate safeguards to ensure that energy-intensive data centers pay for their own dedicated grid upgrades rather than shifting those costs onto household ratepayers.
Together, these measures represent a crackdown on utility cost-padding and data center cost pass-throughs. Yet, Governor Newsom rejected additional administrative expansion by vetoing Assembly Bill 353, which would have created an independent Inspector General with auditing powers over the CPUC. While stricter oversight is essential, Newsom’s veto reaffirmed that the responsibility to police monopoly utilities remains squarely with the CPUC itself.
Disclosure and Transparency
As California pours billions of dollars into upgrading its electrical supply and distribution infrastructure, lawmakers passed several transparency measures to give regulators, energy developers, and the public clearer visibility into power flows across the grid.
Senate Bill 905 establishes a public “grid utilization metric” for every circuit on the distribution grid, requiring utilities to disclose exactly where current power lines have underused capacity. Senate Bill 1158 mandates transparent tracking by the California Energy Commission (CEC) and CPUC on the status of utility grid capacity, transmission upgrades, and project approvals. For larger physical projects, Assembly Bill 2493 creates a dedicated Transmission Development Monitor inside the CPUC to track power line construction schedules and expenditures. Together, these bills begin transforming grid planning from a slow-moving utility secret into a transparent public marketplace – even if no explicit target date has been set.
On the commercial side, Assembly Bill 1577 requires large data center operators to disclose their anticipated energy and water usage directly to the CEC before receiving municipal development permits while Senate Bill 1359 forces gas utilities to publish line-item public spending reports on pipeline maintenance and replacement budgets. These legislative moves allow the state to audit the potentially massive resource footprint of tech infrastructure before ground is broken, while also empowering regulators to stop gas utilities from wasting ratepayer dollars on obsolete fossil fuel pipelines.
On the program side, Assembly Bill 1301 expands annual progress reporting for the state’s Equitable Building Decarbonization Program and adjusts reporting schedules for the Family Electric Rate Assistance (FERA) low-income discount program.
However, Newsom vetoed Senate Bills 877 and 878, which would have forced property insurance companies to publish processing timelines and denial rates for regional claims. These vetoes leave wildfire survivors in the dark and allow insurers to delay or deny payouts with zero reputational consequence.
Building Decarbonization and Gas Infrastructure Planning
As California shifts away from fossil fuels, continuing to reinvest in legacy gas infrastructure risks locking the state into a multi-billion-dollar financial liability. As wealthier homeowners electrify, the fixed costs of maintaining underground gas mains are spread across a shrinking customer base, triggering a potential “gas death spiral” where rates surge to cover stranded assets. This could disproportionately burden lower-income renters who lack the upfront capital to transition off gas sooner rather than later.
To address this challenge, lawmakers built upon the framework of Senate Bill 1221, which allows the CPUC and gas utilities to set up up to 30 neighborhood pilot zones where utilities can fund zero-emission alternatives instead of replacing old gas mains. This session, Assembly Bill 2313 and Senate Bill 1359 provided the critical financial tools to make those pilots work in practice.
Under AB 2313, when an individual residential gas service line is replaced, utilities can no longer automatically dig up the street and install a new gas pipe automatically. Instead, the law requires gas utilities to first offer property owners financial electrification incentives, giving homeowners direct support to switch to electric heat pumps and induction stoves As a complement to AB 2313, SB 1359 aligns pipeline asset write-downs with declining gas usage. By shortening depreciation timelines, SB 1359 ensures that utility shareholders absorb future decommissioning costs today rather than dumping those stranded liabilities onto future ratepayers.
Senate Bill 222 tackles administrative friction by creating automated approval standards for residential heat pumps and electric HVAC systems, preventing local building departments from delaying clean appliance installations. For commercial districts, Assembly Bill 2088 authorizes utilities and municipalities to build Thermal Energy Networks, shared underground water loops that transfer what would otherwise be considered waste heat between nearby commercial and residential buildings.
Permitting and Production
To accelerate the deployment of distributed energy resources (DERs), lawmakers enacted targeted permitting reforms. One of the most immediate victories for consumers was Senate Bill 868, which legalized small, portable “balcony solar” arrays with up to 1,200 watts of rated output capacity. Under SB 868, renters and apartment dwellers can plug these portable solar panels directly into a standard home wall outlet without paying utility interconnection fees, waiting for utility permission, or hiring an electrician. For larger clean energy developments, Senate Bill 887 fast-tracked judicial review under the California Environmental Quality Act (CEQA) for geothermal power plants around the Salton Sea, while Assembly Bill 1156 streamlined land-use restrictions under the Williamson Act to allow solar farm construction on fallowed farmland in critically overdrafted groundwater basins. On the coast, Assembly Bill 1448 and Senate Bill 1337 prohibited state tidelands infrastructure from supporting new federal offshore oil development, explicitly redirecting state port facilities toward floating offshore wind turbines.
Simultaneously, California is confronting practical constraints in its transition to a solar-and-wind-dominated grid. Lawmakers ordered state assessments of next-generation, dispatchable zero-carbon energy generation technologies: Assembly Bill 2647 mandates a CEC feasibility study on advanced nuclear reactors by 2028, while Senate Bill 925 requires a commercial fusion roadmap by 2029.
Yet, proposals seeking direct state capital subsidies for nuclear construction failed to advance, reaffirming that private developers and federal financing must fund project construction. Furthermore, Governor Newsom vetoed Senate Bill 34, which sought to restrict the authority of local air quality districts to set strict emissions rules near ports and logistics hubs, a decision criticized for leaving fence-line communities exposed to industrial pollution.
Optimizing the Grid and Wildfire Mitigation
The Legislature also shifted focus toward digital grid management, customer-sited battery storage, and physical hazard reduction.
On the grid side, lawmakers unlocked customer-sited energy generation and storage systems as an alternative to costly utility infrastructure. Senate Bill 913 established a Virtual Power Plant (VPP) framework that compensates residential solar-plus-battery systems for exporting power during severe heatwaves, cutting reliance on dirty peak-fossil plants and reducing grid strain. Senate Bill 905 mandates that utilities use dynamic line ratings and smart grid software to squeeze additional capacity out of existing lines before proposing new construction. This digital pivot succeeded where earlier efforts failed. After Governor Newsom vetoed previous VPP bills (Assembly Bills 44 and 740) in 2025 over unbudgeted agency costs, lawmakers streamlined SB 913 to unlock home battery potential without creating state administrative overhead.
The preference for optimization over physical line expansion connects directly to the state’s wildfire strategy. While digital tools reduce the need for new high-voltage lines in fire zones, Senate Bill 742 cleans up the physical hazards left behind by previous eras of grid expansion. SB 742 requires the CPUC to mandate the systematic removal of permanently abandoned utility lines, poles, and transformers, which act as prime fire ignition sources during extreme wind events, while assigning mandatory utility liaisons to local emergency operations centers during active fires. To protect impacted communities, the Legislature backed this physical cleanup with consumer and labor protections: the Smoke Damage Standards Act (Assembly Bill 1795) establishes legal guidelines to prevent insurers from arbitrarily denying smoke damage restoration claims, while the Cal Fire Workforce Parity Act (Assembly Bill 2129) boosts firefighter compensation and opens state hiring pathways for formerly incarcerated individuals trained in fire camp programs.
Yet the Governor applied the same fiscal discipline to wildfire legislation as he did to grid management. Newsom vetoed Senate Bill 326, which sought to require multi-agency wildfire strategic plans, calling it duplicative of existing Cal Fire operations, and rejected Assembly Bill 1891‘s prescribed burn grants due to General Fund deficits.
Climate Finance Trends
Faced with a multi-billion dollar state budget deficit, California transformed its climate finance strategy this session. Lawmakers moved away from relying on direct General Fund appropriations, pivoting instead toward off-budget financing mechanisms, voter-approved bonds, and restructured Cap-and-Invest (formerly Cap-and-Trade) auction revenues.
A central piece of this financial realignment was Senate Bill 193, a budget trailer bill that restructured proceeds from the Greenhouse Gas Reduction Fund (GGRF), which receives money from California’s Cap-and-Invest carbon auctions. SB 193 directs all interest earned on auction revenues directly back into the clean energy fund and repeals previously appropriated funds to the Department of Forestry and Fire Protection. The bill allocates funding for state administrative costs first, followed by High-Speed Rail operations, and sets aside $800 million for the Affordable Housing and Sustainable Communities Program overseen by the California Department of Housing and Community Development. SB 193 also eliminated rigid statutory formulas governing Cal Fire fuel reduction spending, giving state administrators maximum flexibility to direct funds where fire risks are highest.
What Does It All Mean?
The 2025-2026 legislative session demonstrated a clear willingness in Sacramento to tighten the leash on monopoly utilities, streamline permitting processes, and extract more value from existing grid infrastructure. Bills like AB 1167 (banning utility lobbying charges), SB 905 (public grid utilization metrics), and AB 2313 (gas line electrification choices) offer practical, meaningful tools to protect ratepayers and support neighborhood clean energy, with the exception of community solar. Yet when viewed against the sheer magnitude of the climate crisis and the crushing reality of household utility bills today, these legislative victories expose a deeper, more uncomfortable truth: California is attempting to fine-tune a system that is fundamentally broken.
Incremental transparency, faster permit approvals, and tighter spending audits are useful, but they do not alter the underlying model. By focusing on tweaking regulatory dials, state leaders continue to favor administrative oversight over transformative execution. For example, setting up a new Transmission Development Monitor inside the CPUC (AB 2493) creates auditing accountability, but audits alone will not resolve the environmental litigation, CEQA review backlogs, or supply chain bottlenecks delaying high-voltage power lines. Similarly, high-level studies on fusion and advanced nuclear (SB 925, AB 2647) will yield valuable reports, but deliver zero clean megawatts to the grid in the immediate term. Meanwhile, Sacramento continues to protect the interests of investor-owned utilities: bills like AB 2463 encourage lower returns without setting hard caps on corporate profits, carve-outs like AB 1301’s co-op exemption leave rural consumers vulnerable, and Governor Newsom’s veto of AB 1813 (community solar and storage) continues to freeze renters and lower-income families out of affordable rooftop energy.
The quiet death of Senate Bill 332 in 2025, which would have studied non-profit, public power models, symbolizes Sacramento’s ongoing reluctance to confront the root cause of our energy crisis. Restraining private monopolies is not the same as replacing them. To achieve a rapid, truly equitable clean energy transition, California needs a fundamental re-evaluation of its entire utility market, moving aggressively toward municipalization, public power, and non-profit energy distribution.
Achieving real market reform also requires unburdening electric bills and eliminating administrative fragmentation. Currently, California’s electricity rates are inflated due to non-grid policy expenses, including multi-billion-dollar wildfire liabilities and legacy disaster recovery costs. Such policy expenses must be decoupled from electric rates so that electrifying a home, a business or a vehicle can actually be cost-effective in the long-term. At the same time, Sacramento must dismantle the confusing, fragmented maze of state, local, and utility clean energy programs. California needs unified, direct administration that delivers a streamlined pathway to more affordable, deep building retrofits without bureaucratic hurdles.
Crucially, state leadership must stop treating climate resilience, infrastructure planning, housing affordability, and building decarbonization as separate policy silos. True climate equity demands that housing stability, structural decarbonization, and extreme weather adaptation happen synchronously. Swapping out a gas furnace for an electric heat pump offers little relief if a home lacks basic insulation, suffers from structural degradation, or traps lethal indoor heat during summer heatwaves.
