SB 559 California Senate · 2025-2026 Regular Session

Electricity: deenergization events: communications.

Summary
Existing law requires each electrical corporation to annually prepare a wildfire mitigation plan and to submit the plan to the Office of Energy Infrastructure Safety for review and approval, as specified. Existing law requires a wildfire mitigation plan of an electrical corporation to include, among other things, protocols for deenergizing portions of the electrical distribution system that consider the associated impacts on public safety, and protocols related to mitigating the public safety impacts of those protocols, including impacts on critical first responders and on health and communications infrastructure. Existing law requires a wildfire mitigation plan of an electrical corporation to also include appropriate and feasible procedures for notifying a customer who may be impacted by the deenergizing of electrical lines and requires these procedures to consider the need to notify, as a priority, critical first responders, health care facilities, and operators of telecommunications infrastructure with premises within the footprint of a potential deenergization event. This bill would require, consistent with the above-described protocols, an electrical corporation to immediately notify, when possible and at the time a decision to conduct a deenergization event is made, public safety partners about the potential public safety impacts of the deenergization event, as specified. The bill would require detailed status information on restoration efforts to be made available to emergency management organizations, public safety officials, customers, and the public, where feasible, with regular progress updates issued at intervals of no more than 12 hours, for all impacted circuits, as specified. The bill would require, in advance of a deenergization event, an electrical corporation to make a reasonable effort to publish and make available weather conditions observed within the affected circuit being considered for deenergization, as provided. Once hazardous conditions subside, the bill would require an electrical corporation to prioritize the restoration of electricity and begin efforts to reenergize lines without unnecessary delays when safe to do so. The bill would make electrical corporations responsible for the continual monitoring and eventual restoration of circuits affected by a deenergization event. The bill would require each electrical corporation to submit an annual report to the Public Utilities Commission that details its compliance with the transparency and restoration requirements of these provisions, as provided. This bill would require the commission to oversee each electrical corporation's compliance with these provisions to ensure that electrical corporations are meeting the transparency, communication, and restoration requirements. If an electrical corporation fails to comply with any of these provisions, including by failing to publish required weather data, notify public safety agencies, or meet communication standards, the bill would authorize the commission to impose financial penalties. Under existing law, a violation of any order, decision, rule, direction, demand, or requirement of the commission is a crime. Because this bill requires action by the commission to implement its requirements, and because a violation of that action would be a crime, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

MAJOR
The Senate amendment to SB 559 significantly softens many mandatory requirements by adding qualifiers such as 'where feasible,' 'where reasonable,' 'make a reasonable effort,' and 'when safe to do so.' It removes the specific four-hour inspection commencement threshold tied to wind speed limits, shifts notification timing from the start of a deenergization event to when the decision is made, and ties key definitions to commission-adopted protocols under Section 8386. These changes reduce the strictness of compliance obligations on electrical corporations while preserving the overall framework of transparency and restoration requirements.
DEFINITION

The definition of 'critical infrastructure' was renamed to 'critical facilities and infrastructure' and expanded to include drinking water and wastewater facilities, carrier infrastructure, and a reference to protocols adopted by the commission under Section 8386(c)(6) and (7).

REQUIREMENT

Notification timing changed from 'at the start of a deenergization event' to 'at the time a decision to conduct a deenergization event is made,' requiring earlier notification to public safety partners including emergency response providers and first responders.

The requirement to maintain direct lines of communication with public safety agencies was softened from a mandatory 'shall maintain' to 'shall make every effort to maintain.'

Restoration priority for circuits with critical facilities was qualified with 'where reasonable,' making it less absolute.

Real-time public availability of restoration status information was qualified with 'where feasible,' reducing the strictness of the requirement.

Weather data publication changed from a mandatory 'shall publish' to 'shall make a reasonable effort to publish,' and the timing shifted from 'at the start of' to 'in advance of' the deenergization event. The list of required data items changed from 'shall include all of the following' to 'may include all of the following.'

Hourly weather data updates during a deenergization event were softened from 'shall publish and make available' to 'shall make reasonable efforts to publish and make available.'

The reenergization requirement was qualified with 'when safe to do so,' adding a safety exception to the 'without unnecessary delays' standard.

The condition for initiating inspection and restoration was expanded from 'observed weather conditions permit' to 'observed weather conditions and safety considerations permit.'

TIMELINE

The specific requirement that inspection of deenergized circuits commence within four hours of windspeeds falling below 25 mph and wind gusts not exceeding 40 mph was removed and replaced with the more flexible standard of 'as soon as it is safe to do so.'
