2021 Nuclear Decommissioning Cost Triennial Proceeding

On December 14, 2021, PG&E filed the 2021 Nuclear Decommissioning Cost Triennial Proceeding (NDCTP) with California Public Utilities Commission (CPUC).  This cost estimate must be updated and filed with the CPUC every three years.

The updated 2021 Decommissioning Cost Estimate for DCPP is $4.1B (2020$), which is a cost savings of $300M compared to the approved settlement for the 2018 NDCTP. A key highlight of the revised cost estimate is transferring all spent nuclear fuel (SNF) to dry cast storage at the Independent Spent Fuel Storage Installation (ISFSI) after 3.25-years of cooling in the spent fuel pools (contingent upon necessary regulatory approvals).  The 2018 NDCTP assumed transfer after 10-years of cooling.  The Diablo Canyon Decommissioning Engagement Panel’s Strategic Vision document was also included in the 2021 filing.

Interested parties will have 30 days to file a response or protest PG&E’s application and, in turn, PG&E will have 10 days from the end of the 30-day period to file a reply to parties.  The CPUC administrative law judge (ALJ) will announce and hold a prehearing conference and issue a scoping memo to identified parties/intervenors with the determined issues, procedural schedule and the need for hearings. The CPUC has 18 months to issue its Proposed Decision, after which a 20-day public comment period will follow. The CPUC commissioners will vote on a final decision no sooner than 30 days from when the Proposed Decision is issued.
