Transmission Project Review Process
With the passage of CPUC Resolution E-5252 on April 27, 2023, the Commission established the Transmission Project Review (TPR) Process for the state’s investor-owned electric utilities (IOUs) beginning January 1, 2024. The purpose of the TPR Process is to have a uniform process to review IOUs’ capital transmission projects, allowing the CPUC and Stakeholders to receive robust data from Transmission Owners, and to inquire about and provide feedback on the IOUs’ historical, current, and forecast transmission projects.
The TPR Process provides useful information to numerous programs and proceedings at the CPUC. These include: California Environmental Quality Act (“CEQA”) review and permitting, Integrated Resource Planning (“IRP”), the Distributed Energy Resources (“DER”) Action Plan, General Rate Cases (“GRC”), wildfire mitigation and recovery efforts, and the CPUC’s Risk-Based Decision-Making Framework (“RDF”) and Risk Assessment & Mitigation Phase (“RAMP”).
The descriptions of data fields to be included in the TOs' transmission project data is linked here: Resolution E-5252 Atch B TPR Process Data Template.
