The 2019 Gas Transmission and Storage (GT&S) Rate Case Final Decision (D.) 19-09-025, issued on September 23, 2019, adopted the Natural Gas Storage Strategy (NGSS) that substantially change PG&E’s gas storage asset holdings and CGT’s role in the market and operational functions. The NGSS balances PG&E’s system reliability and increased gas storage costs due to new storage maintenance regulations. In addition, as of part of the NGSS, the Commission adopted PG&E’s proposal to decommission the Los Medanos and Pleasant Creek fields. On January 31, 2020, PG&E filed with CPUC a plan to market the assets for sale. However, the sale of Los Medanos will not proceed until after PG&E files with the CPUC in 2022 showing McDonald Island will have adequate capacity to meet the reliability needs of the system.
Effective April 1, 2020, the PG&E firm storage services are shown in the table below:
Storage Services | Injection (mmcf/d) | Inventory (bcf) | Withdrawal (mmcf/d) | |||
