  "textContent": "Today's roundup includes the following items.\n\n  * **Interconnection** : A scoping memo in the Rule 21 Update proceeding indicates that the OIR's initial phase will focus on whether the CPUC should:\n    * Modify technical screening tools used to evaluate grid impacts;\n    * Revise interconnection timelines and compliance benchmarks established in 2020; and\n    * Reconsider the **$800** flat interconnection application fee currently applied to non-Net Energy Metering and non-Net Billing Tariff resources.\n  * **PG &E 2027 General Rate Case:** An amended scoping memo expands this proceeding to address Assembly Bill 2666 and Assembly Bill 2847, which require the CPUC to examine utilities’ actual-versus-forecasted rates of return, and to evaluate the revenue-requirement impacts of proposed capital expenditures in future applications.\n  * **Risk Assessment and Mitigation** : A ruling in the Sempra IOUs' Risk Assessment Mitigation Phase docket directs SoCalGas and SDG&E to provide additional information regarding their 2025 RAMP filings, which will inform the utilities’ upcoming Test Year 2028 General Rate Case application. The ruling demands greater transparency from the IOUs.\n  * **SCE 2022 ERRA Compliance:** A new Edison advice letter implements the CPUC’s January decision in its 2022 Energy Resource Recovery Account compliance proceeding.\n  * **PG &E ERRA Trigger**: PG&E filed an advice letter to establish its 2026 ERRA trigger amount. Based on 2025 generation-related revenues, PG&E sets the 4% ERRA trigger amount at **$166.5 million** and the 5% threshold at**$208 million**. If its net ERRA balance reaches the trigger level and approaches the threshold, PG&E must file an application proposing rate changes to amortize the balance.\n  * **PG &E Hinkley Compressor Station**: An ALJ ruling in PG&E's application for a Certificate of Public Convenience and Necessity to construct electrical upgrades at the S-238 Hinkley Compressor Station directs PG&E to provide additional information regarding its recent motion to withdraw the application and pursue the project under an emergency exemption.\n  * **Load Control:** SCE filed a report describing the results of its Load Control Management System pilot, a two-year program that tested whether customer-owned load-control technology could allow new electric loads to be energized in grid-constrained areas before distribution upgrades are completed.\n  * **Public Safety Power Shutoffs:** PG&E, SCE, and SDG&E each submitted their 2025 Public Safety Power Shutoff Post-Season Reports in the CPUC’s de-energization rulemaking (R.18-12-005). The filings are compliance updates, but they help finalize the official record of 2025 PSPS operations.\n\n\n\n### This post is for subscribers only\n\nBecome a member to get access to all content\n\nSubscribe now",
