SDG&E planning policy manager Yi Li and engineer Zohay Batik described the utility’s implementation: when a substation serves 15 or fewer customers, or a single customer consumes 15% or more of a substation’s load, SDG&E displays the substation footprint on the portal but withholds the substation’s generation and load totals and disables the substation profile download. For circuits that fail the 15/15 test, SDG&E blocks display and download of ICA results (generation and load ICA outputs) for line sections on those circuits.

Why it matters: Several stakeholders said SDG&E’s implementation goes beyond protecting customer privacy and can materially reduce the usefulness of the ICA map, particularly where many circuits feed military bases or critical customers — SDG&E staff said such customers are precisely why protections are necessary.

Stakeholder concerns and requests:
- IREC and developers asked SDG&E to quantify how many circuits and what share of the territory are affected by 15/15 redactions and to offer case‑by‑case access processes for legitimate developers or public agencies who need the data (NDAs, direct data requests, or secure portals).
- Advocates said utilities should limit redaction to the minimal fields required to protect customer confidentiality rather than suppressing broader ICA results.

SDG&E response: SDG&E said its redaction approach follows CPUC ALJ rulings and the utility’s Tier 2/Tier 3 filings in prior proceedings. The utility offered to provide further detail in its biannual reporting and in the remediation Tier 3 advice letter, and said it will accept specific requests to provide data to authenticated customers under controlled processes.

What remains unresolved: Parties asked CPUC staff to review whether broader ICA fields (for example, volt/thermal limit flags) can be published without exposing customer telemetry; SDG&E said it will provide additional counts of affected circuits in upcoming filings and can review case‑by‑case disclosure under NDAs.","mediaType","Video","parentTitle","Integration Capacity Analysis (ICA) Workshop Q2 2025 R.21-06-017","oneSentenceSummary","San Diego Gas & Electric said its ICA portal redacts ICA results and hourly profiles for circuits or substations that fail the CPUC’s 15/15 customer‑privacy threshold; developers and advocates asked the commission to require more narrowly targeted redactions and to quantify how much data is masked.","taxTitle","California Public Utilities Commission, Boards and Commissions, Executive, California","taxId",77657,"location","California","headline","","shortSummary",{"_33":77,"_35":36,"_37":38,"_39":78,"_41":79,"_43":80,"_45":81,"_47":82,"_49":83,"_51":84,"_53":85,"_55":56,"_57":58,"_59":86,"_61":62,"_63":64,"_65":87,"_67":68,"_69":70,"_71":72,"_73":74,"_75":74},6178991,"Utilities point to data and modeling limits — AMI telemetry, LTCs and a new LTPT tool — as causes of ICA inaccuracies",300,1403000,1703000,"/Search/View?dp=1&key=5134850-703f3afbb6bbd6fdf88bd0a5d9443edc&start=1403&end=1703","https://assets.pipeline.soar.com/5134850-703f3afbb6bbd6fdf88bd0a5d9443edc/thumbnail_1403000.jpg","/articles/6178991/California/Utilities-point-to-data-and-modeling-limits-AMI-telemetry-LTCs-and-a-new-LTPT-tool-as-causes-of-ICA-inaccuracies","https://secure.pipeline.soar.com/6178991-cce0cd2327f5bbd45549c67af1cc0943/orig.mp4?Expires=1771208214&Signature=UItQRBQv63endepQzVdkrKf7H5Li039xpvA0XpTRgo3gxwwtAM02q1s1f66yMmhAA6y~k1SsZmMj0DtA0OzMr5IGFHP9GRbDSD4e6AHccexw~8zD3Gr~ymF4uLp5mlsjajwiF0inWMPWAcDhAziXQ76Xep33l0Sro1exNQna6ZN-eIyJXC2pn0Qf1gQc0hq23i0-Yk5rPKGjd2DUFMM3S3xpkNwDQROJSB4aEQ~eVTnrFAnSQ0B3flSDDVWViaw0WfWs~8JjDaUAR0iEVMpzCKBTLgNzUtQmdpJzXANOEjGQ6gyU0WJHYKTTIZti0WftEgjm8crsyUMfE9eefPgSlQ__&Key-Pair-Id=KUT5TJCACFTXG","Utility engineers at the CPUC’s quarterly ICA workshop described technical drivers behind a large share of zero hosting‑capacity results and said the next major improvements depend on richer telemetry and a multi‑year tool build.

SCE, PG&E and SDG&E told stakeholders that common technical contributors to 0‑capacity outputs include low source voltage episodes captured in time‑series profiles, conservative study thresholds, missing transformer or substation telemetry, and model backfilling where historical AMI or SCADA data are unavailable. SCE engineers explained that their steady‑state voltage (SSV) studies use a ±3% tolerance around a 120‑volt baseline (resulting in a 118–126 volt threshold) and that adjusting lower‑limit assumptions yielded only modest improvements in zero counts.

Key technical fixes discussed:
- Telemetry and AMI: Utilities said Advanced Metering Infrastructure (AMI2) rollout and improved substation telemetry would materially improve input quality. PG&E and SCE said AMI2 is expected to arrive in stages over several years (SCE cited 2028 in testimony for improved AMI inputs) and that better voltage reads will reduce the need to backfill missing data.
- Long‑term planning tool (LTPT / LPTTSMT): SCE and PG&E are building centralized long‑term planning and system modeling platforms intended to unify planning assumptions, allow unbalanced flow analysis, and incorporate forecasted loads and planned projects. SCE said an engineering dashboard and LTPT milestones are targeted for delivery through 2025–2026 with additional capabilities into 2028.
- Modeling choices and thresholds: Utilities said hourly time‑series methods, selection of a ‘‘most‑limiting hour’’ vs. node‑hour averaging, and how volt‑VAR support is simulated materially change outcomes. SCE noted volt‑VAR support is simulated only when network voltage drops below approximately 97% of nominal, which can leave some SSV violations unmitigated in the model.

Interim operational steps: Utilities described automation to reduce manual model fixes and a new batch refresh trigger for monthly ICA publication that prioritizes circuits with critical system changes, Rule 21 fast‑track applications, or long refresh gaps. They said automation and additional compute capacity would enable more predictable refresh cadence.

Stakeholder reaction: Engineers and advocates pressed utilities to identify near‑term practical measures for improving the accuracy that do not require waiting for AMI2 or a full tool rewrite. PG&E and SCE said they are testing incremental fixes (capacitor setting changes, backfill improvements) but that many solutions depend on telemetry or cross‑team coordination.

Bottom line: Utilities argued most zeros reflect real limiting conditions under current inputs; stakeholders replied that better telemetry and clear remediation timelines are necessary for ICA to function as an actionable developer tool.","Utility staff at the CPUC ICA workshop said many zero‑capacity results stem from conservative study assumptions, limited telemetry (AMI/SCADA) and model limitations; they described long‑term tool builds, telemetry upgrades and interim automation to improve results.",{"_33":89,"_35":36,"_37":38,"_39":90,"_41":91,"_43":92,"_45":93,"_47":94,"_49":95,"_51":96,"_53":97,"_55":56,"_57":58,"_59":98,"_61":62,"_63":64,"_65":99,"_67":68,"_69":70,"_71":72,"_73":74,"_75":74},6178994,"Stakeholders press utilities over ‘0 capacity’ results, inactive circuits; CPUC deadline for remediation letters looms",2708,1041000,3749000,"/Search/View?dp=1&key=5134850-703f3afbb6bbd6fdf88bd0a5d9443edc&start=1041&end=3749","https://assets.pipeline.soar.com/5134850-703f3afbb6bbd6fdf88bd0a5d9443edc/thumbnail_1041000.jpg","/articles/6178994/California/Stakeholders-press-utilities-over-0-capacity-results-inactive-circuits-CPUC-deadline-for-remediation-letters-looms","https://secure.pipeline.soar.com/6178994-c511b2547ae197905cdbd0f88a606f54/orig.mp4?Expires=1771208214&Signature=HKI5up3XGJw9j8HvUZ4Ns3Cn72WpPhF7GPNzKYT-5WiwAjEtqR1svsG1WrnVMXfF~~K0WWnJFNgS-KEiE1D3TnYW6SEVeEu1AOYsCrYy6liYd-w5YOESNtv3BAnY~af8o-NI7d5KlKcYi4cI0HmbAdlPqlBJ4XcyDUx2qduMOq2HxqwMsyjgOqMDtr~lhym7cCdlrw3gWGye-Eja-cxhrCarNUeUq7kxC2GaTZ8Yx0YX8x1KeHB0rrykhxPPaMOE5IXH6Q8pc5TLFwm-pkirQwZqpAqUUkDJtrLjqslLxjTuZXaIk23fB01HSuFq2dAHzKPksujBmq5ACcsTLUCKOA__&Key-Pair-Id=KUT5TJCACFTXG","Stakeholders pressed Southern California Edison, PG&E and SDG&E at a California Public Utilities Commission workshop for clearer timelines to fix two linked problems: circuits excluded from ICA publication (so‑called inactive circuits) and a high number of nodes or segments that show zero available hosting capacity.

The arguments: dozens of developers and advocacy groups said the current ICA outputs are not reliably actionable for siting projects such as EV chargers and solar plus storage. IREC commenter Skye Stanfield said utility ICA results are ‘‘leaning on the slightly conservative side’’ but warned the large share of zeros and circuits marked inactive makes the map unreliable for developers.

Why it matters: Stakeholders said the errors cause unnecessary development cost and delay by screening sites out of fast‑track interconnection workflows when, they argue, the site could be serviceable after an engineer review or minor adjustments.

Facts and figures reported at the workshop:
- SCE said it has reactivated 122 circuits since its 2023 systemwide ICA refresh, including 86 that had primary‑metered customer constraints; SCE said another set of circuits are being addressed and that some remain ineligible for ICA for reasons such as decommissioning.
- PG&E, SCE and SDG&E reported varying shares of published circuit results that were recently refreshed; utilities said publication cadence and prioritization will continue to change as new automation and compute capacity come online.

CPUC action and next steps: Energy Division staff and attendees noted Decision 24 10 0 3 0 requires utilities to file Tier 3 advice letters proposing remediation plans. CPUC staff announced a schedule: utilities must submit Tier 3 advice letters within 60 days of the workshop (published workshop comments set a filing target of August 26, 2025), opening a 20‑day comment period on each filing. Energy Division’s Gabe Petlin told the room that the advice letter process is the vehicle to set remediation timelines and that, when approved, a resolution will place binding expectations on the utilities.

Stakeholder demands: Public Advocates Office, IREC, 350 Bay Area, CalStart and others asked that remediation advice letters include (1) binding schedules for reactivating inactive circuits and decreasing zeros, (2) resource and budget estimates for the work, and (3) measurable quality‑assurance or accuracy milestones so parties can assess progress.

Utility response: Utilities said they were working to prioritize circuits with the greatest near‑term impact (Rule 21 applications, circuits with long refresh intervals or known critical changes) and that limited compute and engineering capacity constrained full monthly refresh of all circuits. PG&E said it can refresh a large share of its system each month but that some workflows require engineer intervention where automated checks flag problems.

What remains unresolved: Parties differed over whether the CPUC’s existing orders already require monthly updates of circuits that ‘‘trigger’’ a refresh; utilities said there are reasonable exceptions while stakeholders asked the commission for firmer guidance. The Tier 3 advice letters are expected to be the forum to settle scope, resources and enforcement.","Developers and advocates at a CPUC ICA workshop pressed utilities over a persistent share of ‘0 capacity’ hosting‑capacity results and a large number of circuits excluded from ICA reporting; CPUC directed utilities to file Tier 3 remediation advice letters within 60 days.",{"_33":101,"_35":36,"_37":38,"_39":102,"_41":103,"_43":104,"_45":105,"_47":106,"_49":107,"_51":108,"_53":109,"_55":56,"_57":58,"_59":110,"_61":62,"_63":64,"_65":111,"_67":68,"_69":70,"_71":72,"_73":74,"_75":74},6178999,"CPUC utilities roll out limited-generation profiles, update ICA portals",2977,1999000,4976000,"/Search/View?dp=1&key=5134850-703f3afbb6bbd6fdf88bd0a5d9443edc&start=1999&end=4976","https://assets.pipeline.soar.com/5134850-703f3afbb6bbd6fdf88bd0a5d9443edc/thumbnail_1999000.jpg","/articles/6178999/California/CPUC-utilities-roll-out-limited-generation-profiles-update-ICA-portals","https://secure.pipeline.soar.com/6178999-3dfc1340867bec8d16a49f828398a424/orig.mp4?Expires=1771208214&Signature=T7dZ6ac-pCma9VzOU0N20QwuGLRgPgoYHu1Oe1kKsofITp1-x4sa0TaY4mK9sExuTpuh~gPFwq1zov8r8dW-ZYzKPaibgAGyZYHSGnlvkosarYbv6oLZfCDDUQVPTQY3W9IHrrkJ5yZigNt6gq5xLJXzZhcIYizr1p0eEkd6bAy4LrAij6yMlaxhp7KxWIpK8k9gHi8k3uUYqcmiWgHf98OsBvYob1izQdsGpBy3ygtjYcXees~GINPxXJi7W7HYq4~WNHF4kCxvM4Ewwdvj~LaIg81y~K7FJpx7BtKly8xpnKOd4h2wWj7m9Z1uWAX6Cl~3A2fKIF2x3k4cBFscOQ__&Key-Pair-Id=KUT5TJCACFTXG","Southern California Edison, Pacific Gas & Electric and San Diego Gas & Electric told stakeholders at a California Public Utilities Commission (CPUC) workshop that they are releasing new features to make Integrated Capacity Analysis (ICA) data and limited generation profile templates available to customers.

The utilities emphasized the work is incremental and that further platform changes are on a multi‑quarter timeline. ‘‘The ICA quantifies the maximum amount of power that can be injected to or drawn from the distribution system while requiring minimal to no distribution mitigations, upgrades, or operational restrictions,’’ Audrey Newman, energy advisor and interim deputy chief of staff to Commissioner Haug, said in opening remarks for the CPUC.

Why it matters: LGP templates and clearer portal downloads are intended to help customers prepare interconnection applications under Rule 21 by supplying a machine‑readable, utility‑provided maximum export or import profile tied to the ICA results. SCE, PG&E and SDG&E said the new downloads will be integrated into their portals so customers can retrieve LGP CSV templates for specific line segments.

Key points from each utility:
- Southern California Edison said its Doctor Pepp portal will make LGP templates available and that the company expects the capability to be visible to customers “effectively on June 30,” and to follow the formats described in the IDR decision and Resolution E5230. SCE product lead Assad Pucks said users will be able to click a downloadable tab and get a prepopulated spreadsheet to use when preparing an LGP application.
- PG&E reported a recent portal release that added LGP hourly data and charting to its Grid Resource Integration Portal and plans further UI and API improvements through the year; product manager Julia Anderson said the team had just pushed a major release for LGP and “the limited generation profile data is now available for access through the map interface on the data portal.”
- SDG&E said customers will be able to download LGP templates for a selected ICA segment in its portal starting next month and that user guidance will be updated to show where to find the files.

Supporting detail: PG&E and SCE also described multi‑phase road maps for broader portal and ICA feature improvements — sub‑transmission capacity heat maps, study sublayers and expanded API downloads — with additional updates slated later this year and into 2026. Utilities said the packages are being developed alongside larger planning‑tool builds that will centralize planning inputs.

Stakeholder reaction: Developers, advocates and rule‑making participants welcomed the LGP file availability but pressed for clarity on publication cadence and accuracy. Several parties said they will treat LGP templates as helpful only if the underlying ICA results are current and reliable.

What’s next: Utilities said LGP templates will be published to their portals in the coming days to weeks (SCE: June 30; PG&E: recent release; SDG&E: next month) and that additional portal and ICA enhancements will roll out through late 2025 and into 2026. The CPUC has directed utilities to include remediation plans in upcoming Tier 3 advice letters (see related coverage).","Southern California Edison, PG&E and SDG&E reported incremental improvements to their integrated capacity analysis tools and data portals and said they will publish limited generation profile (LGP) templates in coming weeks to let customers download LGP values for interconnection applications.","actionData","errors"]
