Summary of AB 527: California Environmental Quality Act Amendments for Geothermal Projects

Bill Overview

Bill Number: AB 527
Title: California Environmental Quality Act: Geothermal Exploratory Projects, Geothermal Field Development Projects, Enhanced Geothermal System Wells
Introduced: October 15, 2025
Status: Consideration of Governor's veto pending

Purpose and Intent

AB 527 aims to amend the California Environmental Quality Act (CEQA) to facilitate geothermal exploratory projects and enhance the development of geothermal energy resources in California. The bill seeks to streamline the regulatory process for geothermal projects while ensuring environmental protections are maintained.

Key Provisions

  1. Definition and Scope of Geothermal Projects:

    • Expands the definition of "geothermal exploratory project" to include equipment and activities necessary for establishing interconnectivity between wells and geothermal reservoirs.
    • Excludes certain wells connecting to geothermal reservoirs from the existing one-half mile distance requirement from production wells.

  2. CEQA Exemptions:

    • Provides a temporary exemption from CEQA for geothermal exploratory projects that meet specific conditions until January 1, 2031.
    • Requires project developers to conduct a reconnaissance survey and submit it when applying for the exemption.

  3. Environmental Reporting Requirements:

    • Mandates that logs for wells in exempt geothermal exploratory projects include the chemical and physical characteristics of well stimulation fluids.
    • Requires disclosure of the composition of fluids used in hydraulic fracturing operations.

  4. Consultation and Notification:

    • The lead agency must engage in scoping consultations with California Native American tribes traditionally affiliated with the project area.
    • Requires public notification at least 30 days prior to the approval of an exemption, including posting notices at the project site and on the agency's website.

  5. Regulatory Framework:

    • Directs the Geologic Energy Management Division to develop regulations for enhanced geothermal system wells by January 1, 2029.
    • Establishes that no reimbursement is required for local agencies or school districts for costs mandated by this act.

Impact

  • Affected Parties:

    • Geothermal project developers will benefit from streamlined processes and reduced regulatory burdens.
    • Local governments and California Native American tribes will have a role in consultations and oversight.

  • Environmental Considerations:

    • The bill aims to balance the need for renewable energy development with environmental protections by maintaining certain reporting and consultation requirements.

Procedural Aspects

  • The bill has undergone several amendments and committee reviews since its introduction, reflecting ongoing discussions about its implications.
  • It is currently pending consideration of a veto by the Governor, indicating that its future is uncertain.

Conclusion

AB 527 represents a significant legislative effort to promote geothermal energy development in California while attempting to address environmental concerns through regulatory adjustments. The bill's success will depend on its reception by the Governor and the broader implications for energy policy in the state.
