Diablo Canyon Power Plant Potential Continued Operations Presented by:

Maureen Zawalick Vice President, Business and Technical Services March 16, 2023

Internal Topics

  • Diablo Canyon Power Plant (DCPP) Overview
  • CA History of Nuclear
  • Concurrent Planning Paths
  • Near-Term Milestones 2

Internal DCPP Overview

  • DCPP operations began:

- Unit 1: May 1985

- Unit 2: March 1986

  • Current operating license expirations:

- Unit 1: November 2024

- Unit 2: August 2025

  • 9% of CAs energy
  • ~20% of CA carbon free energy 3

Internal Californias History in Nuclear California was a pioneer in early nuclear GE/PG&E obtained Atomic Energy Commission power reactor license #1

Internal Nuclear in California DCPP is the last operating nuclear plant in California

Internal PG&E Stands and Virtues 6

Internal State and Federal Changes Due to Projected Energy Shortfall Assembly Bill (AB) 180

  • Signed by the California Governor on June 30, 2022
  • Authorized $75 million for near-term fuel purchasing, fuel storage, licensing and project team to preserve option of extended DCPP operations Senate Bill (SB) 846
  • Signed by the California Governor on September 2, 2022
  • Directed PG&E to pursue continued operations for 5 years beyond 2025
  • Addresses both near-term and long-term funding needs
  • Includes state policy "off ramps" that could terminate the path of renewing the operating licenses U.S. Department of Energy Civil Nuclear Credit Program
  • DCPP has been certified to participate in the programs first award period 7

Internal Why Now? Immediate Actions Underway

1. Fuel Purchasing: Two-year lead time - working on fuel for outages in 2024 and beyond
2. Spent Nuclear Fuel Storage: up to two-year lead time to contract, manufacture, transport, and load canisters to support continued core reloads
3. Regulatory Processes: Complex federal and state applications underway for permits and funding - including State of CA, and Federal (NRC license renewal (LR) application and US Dept. of Energy (DOE) civil nuclear credit program)
4. Organization: Restarted LR application preparation, inspection program development, organizational adjustments, and implementation of LR NRC commitments as directed by SB 846 8

Internal Being Nimble and Tenacious

  • Diablo Canyon has a great track record at being tenacious
  • Our industry needs to work at being nimble
  • Need to deliver for our hometowns and our planet The industry needs to embody these traits in todays dynamic regulatory environment 9

Internal Paths Due to California Energy Policy Changes SB 846 Enacted (Sep 2, 2022)

DCPP license renewal efforts with NRC and State agencies Dept of Energy conditionally granted PG&E Civil Nuclear Credit funds (up to $1.1B)

Coordination with States Secretary of Natural Resources Employee retention

1. DCPP Retirement 2024/2025

Continue key decommissioning planning to secure items already in progress

  • Diablo Canyon Decommissioning Engagement Panel
  • San Luis Obispo County: Decommissioning development planning
  • Nuclear Regulatory Commission (NRC): Decommissioning license actions
  • CA Public Utilities Commission: Nuclear Decommissioning Cost Triennial Proceedings
  • Diablo Canyon land activities
2. DCPP Continued Operations 10

Internal Near-Term Milestones By Q1 2023 CEC and CPUC provide joint Reliability Planning Assessment identifying estimates for the electrical supply and demand balance for the forward 5-and 10-year period under high-, medium-, and low-risk scenarios CPUC to open new proceeding focused on SB-846 implementation NRC determine regulatory approach for License Renewal Application CEC, CAISO, and CPUC determination on need to extend DCPP operations to ensure reliability 11 CEC: CA Energy Commission CAISO: CA Independent System Operator CPUC: CA Public Utilities Commission

Internal CPUC: CA Public Utilities Commission LSE: Load-Serving Entities Near-Term Milestones (continued)

By Q2 2023 PG&E to make a filing with the CPUC containing detailed description of accounting structure for DCPP continued operations cost recovery after holding a meet and confer with CPUC-jurisdictional LSEs File application for extension of DCPP Employee Retention Program Engage CA Legislature regarding authorization for remaining Deptartment of Water Resources funding ($800M) and clean-up items from SB-846 12
