About the Siting, Transmission, and Environmental Protection Division
The Siting, Transmission, and Environmental Protection Division has a Siting Office, Compliance Office, Environmental Protection Office, Engineering Office, Strategic Transmission Planning and Corridor Designation Office, and the Administration and Special Projects Office.
Siting and Compliance Offices
The Siting and Compliance Offices manage the power plant siting (licensing) cases, the public review process for, and preparation of, CEQA documents, and the compliance monitoring program. Responsibilities include meeting legally required schedules, procedures, and ensuring coordinated and objective interdisciplinary analysis for power plant licensing so that approved power plants are constructed, operated, and eventually decommissioned in compliance with the Energy Commission's certification.
Environmental Protection Office
The Environmental Protection Office employs experts in biological resources, socioeconomics, land use, and related disciplines. These experts perform independent field investigations; coordinate with various local, state and federal agencies; prepare in-depth analyses; and present expert testimony at hearings relating to the approval and compliant construction and operation of power plants licensed by the Energy Commission.
Engineering Office
The Engineering Office employs experts in engineering, geology, power plant efficiency, reliability and facility design, seismicity, systems analysis and related disciplines including air quality, water resources, and public health experts. The office provides a unique assemblage of engineers and scientists capable of evaluating and presenting expert testimony on all aspects of energy facility design, construction and operation.
Strategic Transmission Planning and Corridor Designation Office
The Strategic Transmission Planning and Corridor Designation Office employs electrical engineers and transmission specialists who conduct transmission system planning, transmission engineering analyses, and transmission corridor designation analyses. The office examines statewide electric transmission issues, assesses the value of proposed in-state and interstate transmission expansion projects, represents the state in various in-state and interstate transmission planning forums, and presents expert testimony on transmission engineering.
Administration and Special Projects Office
The Administration and Special Projects Office performs administrative functions for the division and special projects, including tracking relevant legislation and administering outside division contracts.
