LEGISLATIVE COUNSEL'S DIGEST

SB 593, Hurtado.
 Electrical corporations: significant voltage-related incidents: studies.

Existing law vests the Public Utilities Commission with regulatory jurisdiction over public utilities, including electrical corporations. Existing law requires each public utility to furnish and maintain adequate, efficient, just, and reasonable service, instrumentalities, equipment, and facilities, as are necessary to promote the safety, health, comfort, and convenience of its patrons, employees, and the public.

Existing law requires the commission to annually publish a
 report, pursuant to commission requirements, as provided.

This bill would require the commission, on or before January 1, 2027, to require each large electrical corporation, as defined, to commence a study to evaluate significant voltage-related incidents, as defined, across its residential, commercial, and industrial customers that resulted in damage to customer-owned equipment, appliances, or property totaling $5,000 or more, as provided. The bill would require the commission, on or before July 1, 2027, to publish hyperlinks on its internet website to the studies, and to report on the studies to the Legislature.

Under existing law, a violation of any order, decision, rule, direction, demand, or requirement of the commission is a crime.

Because a violation of a commission action implementing this bill’s requirements 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.

 Voltage changes can be caused by multiple factors, including, but not limited to, lightning strikes, downed electrical lines, or sudden shifts in electrical demand.

(c) It is the responsibility of the Public Utilities Commission to publish public disclosures and information on the adequacy of large electrical corporations’ consumer protections

 percent of nominal voltage and that results in damage to customer-owned equipment, appliances, or property.

(b) (1) On or before January 1, 2027, the commission shall require each large electrical corporation to commence a study to evaluate significant voltage-related incidents across its residential, commercial, and industrial customers that resulted in damage to customer-owned equipment, appliances, or property totaling five thousand dollars ($5,000) or more.
