Senate Bill 901: Wildfire Cost Recovery, Forest Management, and Oversight

California Senate Bill 901 is a 2018 state law, signed by Governor Jerry Brown on September 21 of that year, that rewrote how California handles wildfire prevention, utility liability, and forest management. Authored by Senator Bill Dodd of Napa and enacted as Chapter 626 of the Statutes of 2018, it created a framework for investor-owned utilities to recover certain wildfire costs from ratepayers, directed $1 billion to forest health and fuel reduction, required utilities to submit wildfire mitigation plans, and set up a commission to study whether California’s liability rules needed deeper reform.¹

Why the Law Was Passed

The 2017 wildfire season was the trigger. The Tubbs, Nuns, Atlas, Redwood Valley, and Thomas fires killed more than a hundred people and destroyed over 9,300 structures. PG&E alone faced projected liabilities of at least $2.5 billion, insured property losses potentially exceeded $10 billion, and credit agencies downgraded both PG&E and Southern California Edison.²

Behind the fires sat a legal squeeze. Under California’s inverse condemnation doctrine, utilities were strictly liable for damage from fires traced to their equipment regardless of negligence, a standard applied to private utilities almost nowhere else in the country.³ At the same time, the California Public Utilities Commission had rejected utility attempts to pass those costs through to customers, including a $379 million recovery request from San Diego Gas & Electric after the 2007 fires.² Power lines had been linked to roughly half of the most destructive fires in state history, and hotter, drier conditions were making dangerous fire weather more frequent.⁴

Senator Dodd, whose district had burned in the Wine Country fires, chaired the conference committee that drafted the bill and warned that without a financial stabilization path for utilities, higher borrowing costs would land on customers or the utility would end up in bankruptcy.⁵ Signing the measure, Brown called it “complex” and “absolutely necessary.”⁶

How Utilities Can Recover Wildfire Costs

The financial provisions were the most debated part of SB 901. The law set up two different tracks for deciding whether an investor-owned utility can pass wildfire costs on to ratepayers, depending on when the fire happened.

2017 Fires and the Stress Test

For fires that ignited in 2017, the CPUC was directed to evaluate costs under a “just and reasonable” standard without a detailed multi-factor test. The law then required the commission to run a “financial stress test” to calculate what it called the Customer Harm Threshold: the maximum amount a utility could absorb for wildfire damages without harming ratepayers through higher borrowing costs or impairing the utility’s ability to provide safe service. Any disallowed costs above that threshold could be shifted to ratepayers.⁷

The CPUC adopted the methodology in Decision 19-06-027 in July 2019. It assesses a utility’s maximum incremental debt capacity, excess cash, and regulatory adjustments, aiming to keep the utility at a minimum investment-grade credit rating.⁷ The commission also decided the test could not apply to a utility in bankruptcy, since bankruptcy itself addresses pre-petition debts. That ruling effectively blocked PG&E from using the framework after it filed for Chapter 11 in January 2019.⁸

Fires After 2018

For fires occurring after December 31, 2018, SB 901 authorized the CPUC to apply a more detailed reasonableness review, requiring the commission to consider 12 specified factors when deciding whether wildfire-related expenses can be recovered from ratepayers.⁹ This replaced the CPUC’s previous ad hoc approach with a structured evaluation.

Rate Recovery Bonds

The law also lets the CPUC authorize rate recovery bonds to finance wildfire damages from 2017 or later fires, provided the underlying costs are found just and reasonable. Fines and penalties cannot be financed this way.⁹

What the Law Did Not Touch

Two limits on the law are worth knowing. First, despite heavy utility lobbying, SB 901 did not alter inverse condemnation. Utilities remain strictly liable for damages from fires traced to their equipment, whether or not they were negligent; the bill only created a way to spread those costs over time through borrowing and ratepayer-funded repayment, and only for 2017 fires with CPUC approval. Second, the 2017 cost-recovery framework left a conspicuous gap: it did not cover wildfires that occurred in 2018, including the Camp Fire in Butte County, California’s deadliest wildfire.¹⁰

Forest Management and Prevention Funding

The non-utility half of SB 901 put money and new rules behind reducing fire risk on the land. The law allocated $1 billion from the state’s Greenhouse Gas Reduction Fund to CalFire, broken into annual appropriations of $165 million for forest health and fire prevention and $35 million for prescribed fire and fuel reduction, running through the 2023–24 fiscal year.¹¹¹

Timber Harvest and CEQA Exemptions

To speed up fuel reduction, SB 901 created exemptions from the normal timber harvest plan requirement, which otherwise obliges a registered professional forester to detail harvest methods and environmental protections. Small timberland owners with parcels under 100 acres who are removing trees to reduce flammable materials are exempt, as is tree harvesting specifically aimed at reducing fire spread and crown ignition. These exemptions allow up to 600 feet of temporary roads for forest thinning. Certain fuel reduction, thinning, and prescribed burning projects are also exempt from California Environmental Quality Act review when they have already been reviewed under the federal National Environmental Policy Act.¹²

Conservation Easements

SB 901 added Section 815.11 to the California Civil Code, imposing new management requirements on conservation easements purchased with state funds that include forest land. Landowners must maintain and improve forest health through natural tree density and species composition, increase the land’s capacity for long-term carbon sequestration and watershed function, and retain larger trees with a natural range of age classes.¹³

Community Preparedness

On the community side, the law directed the State Board of Forestry and Fire Protection to develop criteria and maintain a Fire Risk Reduction Community List identifying local agencies in state responsibility areas or very high fire hazard severity zones that meet best practices for local fire planning. CalFire must prioritize local assistance grant funding for communities on that list. The law also created the Wildfire Resilience Program to assist nonindustrial timberland owners with technical guidance, including help navigating permitting.¹¹

Utility Oversight and Penalties

SB 901 added new regulatory obligations for investor-owned electric utilities. Each must submit a wildfire mitigation plan to the CPUC for approval, with the commission required to process the plans within three months unless a written extension is justified. The law doubled the maximum statutory penalty for violations of CPUC orders, decisions, or laws from $50,000 to $100,000 per violation per day. It also required the CPUC to enter a memorandum of understanding with CalFire for data sharing, fire prevention, and vegetation management.⁹ Separately, the law requires the CPUC to conduct safety culture assessments of investor-owned utilities every five years, at shareholder expense.⁴ It also directed the California Air Resources Board, with CalFire, to estimate greenhouse gas emissions from wildfire and forest management and build a historical baseline reflecting conditions before modern fire suppression.¹⁴

Criticism of the Law

Consumer advocates labeled the cost-recovery provision a “bailout.” Senator Jerry Hill, who voted against the measure, said letting utilities develop their own fire prevention plans was insufficient: “My concern is that it allows the utilities to develop the plans themselves, and they haven’t been able to prevent the fires so far.”¹⁰ The Utility Reform Network and the Ratepayer Protection Network opposed the bill on similar grounds.⁵ Some fire victims and insurance companies wanted inverse condemnation left intact without any ratepayer cost-shifting mechanism. Agricultural interests worried about rising electricity rates. The Sierra Club also opposed the bill.¹⁵

What Came After SB 901

SB 901 created a five-member Commission on Catastrophic Wildfire Cost and Recovery, chaired by CPUC Commissioner Carla Peterman and including Dave Jones, Michael Kahn, Pedro Nava, and Michael Wara. The commission held five public hearings in 2019 and delivered its final report on June 17, 2019, finding the status quo unsustainable and recommending that strict liability under inverse condemnation be replaced with a fault-based negligence standard, that a broadly sourced Wildfire Victims Fund be established, and that the homeowner’s insurance market in high-risk areas be reformed. It acknowledged that SB 901 “did not go far enough to manage systemic risk.”¹⁶

Those recommendations fed into AB 1054, signed by Governor Gavin Newsom on July 12, 2019. AB 1054 established a $21 billion Wildfire Fund capitalized equally by ratepayer charges and utility shareholders, pooling risk across the three large investor-owned utilities. It replaced much of SB 901’s 12-factor reasonableness test with a framework tied to a “safety certification” process: a utility holding a valid safety certificate is presumed to have acted reasonably unless another party raises serious doubt.¹⁷ AB 1054 also created what eventually became the Office of Energy Infrastructure Safety, which took over oversight of utility wildfire mitigation plans.³

Several SB 901 mandates remain active. The CPUC continues to conduct safety culture assessments of PG&E, SDG&E, and Southern California Gas, with an open rulemaking (R.21-10-001) to standardize the process.⁴ The forest management funding, however, is now in doubt. SB 840, enacted in September 2025, restructured Greenhouse Gas Reduction Fund priorities, placing wildfire resilience behind state operations and other allocations. Combined with lower projected fund revenue, the Legislative Analyst’s Office has indicated the shift would effectively eliminate wildfire resilience funding from the fund in each of the next four budget years.¹⁸ The core questions SB 901 first tried to answer, about liability, cost allocation, and prevention, remain at the center of California’s wildfire policy debate.
