SB 940 California Senate · 2025-2026 Regular Session

Geologic Energy Management Division: New Technology Program: oil and gas wells: geothermal wells.

Summary
Existing law vests the State Oil and Gas Supervisor with regulatory authority over wells for the discovery of geothermal resources or wells on land producing geothermal resources. Existing law establishes the Geologic Energy Management Division in the Department of Conservation, under the direction of the supervisor, who is required to supervise the drilling, operation, maintenance, and abandonment of oil and gas wells in the state and the operation, maintenance, and removal or abandonment of tanks and facilities related to oil and gas production within an oil and gas field, so as to prevent damage to life, health, property, and natural resources. Under existing law, a person who fails to comply with requirements relating to the regulation of oil or gas operations is guilty of a misdemeanor. Existing law imposes, among other things, an annual charge upon each person operating or owning an interest in an oil or gas well, with respect to the production of the well, which charge is payable to the Treasurer for deposit into the Oil, Gas, and Geothermal Administrative Fund. Existing law requires funds from those charges to be used exclusively for the support and maintenance of the Department of Conservation, which is charged with the supervision of oil and gas operations, for the State Water Resources Control Board and the regional water quality control boards for their activities related to oil and gas operations that may affect water resources, and for the support of the State Air Resources Board and the Office of Environmental Health Hazard Assessment for their activities related to oil and gas operations that may affect air quality, public health, or public safety. Existing law imposes annual limits on expenditures by the division from the Oil, Gas, and Geothermal Administrative Fund, as provided. This bill would establish the New Technology Program within the division to facilitate the evaluation of repurposing oil and gas wells or geothermal wells for renewable energy storage or generation purposes. The bill would require the supervisor to approve or deny project proposals from operators to repurpose oil and gas wells or geothermal wells for energy storage or renewable energy generation, including synthetic geothermal resources, as provided. The bill would require, upon approval of a project by the supervisor, the oil and gas wells or geothermal wells that are part of the project to be designated as experimental wells, as defined, for the duration of the project. The bill would impose an annual charge on operators of experimental wells to defray the regulatory costs incurred by the state, as provided. The bill would require the proceeds of the annual charge to be deposited into the Oil, Gas, and Geothermal Administrative Fund. The bill would require the division to, on or before an unspecified date, and annually thereafter, provide a report to the applicable legislative policy and budget committees on program activities for the preceding calendar year, highlighting accomplishments and including recommendations for statutory and regulatory changes to more readily achieve program goals.

MAJOR
SB 940 was dramatically expanded from a simple definitional amendment to a comprehensive new regulatory program. The original bill only expanded the definition of 'geothermal resources' to include oil and gas reservoirs used for thermal energy storage or geothermal generation. The Senate amendment adds an entire New Technology Program within the Geologic Energy Management Division, establishing a framework for repurposing existing oil and gas or geothermal wells for renewable energy storage or generation, complete with funding mechanisms, a 250-well cap, eligibility rules, and reporting requirements.
SCOPE

Establishes the New Technology Program within the Geologic Energy Management Division to facilitate evaluation of repurposing oil and gas wells or geothermal wells for renewable energy storage or generation purposes (Section 3871).

Requires the program to be implemented in coordination with the State Water Resources Control Board and regional water quality control boards, and requires the division to invite participation of federal agencies with relevant jurisdiction (Section 3878).

Adds legislative findings and declarations stating that existing oil and gas and geothermal laws were written decades ago and do not anticipate repurposing wells for other uses, and that providing a framework for the division to authorize evaluation of new uses is a needed step (Section 1).

DEFINITION

Adds definitions for 'experimental well,' 'synthetic geothermal resources' (an oil or gas reservoir used primarily for thermal energy storage), 'geothermal well,' 'oil and gas well,' 'program,' and 'water boards' (Section 3870).

FISCAL

Imposes an annual charge on operators of experimental wells that are oil and gas wells (Section 3403.7) and a separate annual charge for experimental wells that are geothermal wells (Section 3724.7). Charges are calculated as a proportionate share of total statewide regulatory costs divided by the number of experimental wells. Proceeds go to the Oil, Gas, and Geothermal Administrative Fund.

REQUIREMENT

Caps the total number of experimental wells at 250 statewide at any time (Section 3872).

Requires the supervisor to approve or deny project proposals. Upon approval, wells are designated as experimental wells for the duration of the project, and program personnel facilitate obtaining necessary permits (Section 3874).

Provides that an oil and gas well designated as an experimental well is not considered an idle well under Section 3206, preventing mandatory plugging during the experimental period (Section 3875(b)).

ELIGIBILITY

Excludes Class VI underground injection control wells from program eligibility (Section 3873(b)). The division must issue public guidelines on which project types are eligible.

TIMELINE

Requires the division to develop publicly available guidelines on transitioning between oil and gas wells and geothermal wells by an unspecified date (Section 3876), and to submit annual reports to legislative policy and budget committees beginning on an unspecified date (Section 3877).
