San Diego Gas & Electric: PCIA Bill Transparency

SDG&E filed Advice Letter 4817-E today for approval to change how the Power Charge Indifference Adjustment is presented to bundled customers, in compliance with D.25-09-006 (SDG&E's 2024 General Rate Case Phase 2 decision, from last September).

Instead of embedding PCIA costs within bundled generation rates, SDG&E proposes to show a distinct, volumetric PCIA line item on bundled customer bills and in its Electric Energy Commodity Cost tariffs. SDG&E will calculate class-specific PCIA rates using existing generation allocation factors and forecasted sales, mirroring the structure already used for unbundled customers and avoiding any cost shifts across classes.

The change is framed as a transparency measure, making clear that PCIA is not a fixed charge but a usage-based cost tied to departing load obligations. SDG&E has also established a new PCIA Billing Change Memorandum Account (authorized under the same decision and created via AL 4738-E) to track the incremental costs of implementing the billing, tariff, and rate changes, indicating that it intends to recover implementation expenses from ratepayers.

However, SDG&E notes that implementation will require substantial billing system development, testing, and coordination with other planned 2026 system changes, including a broader cloud migration. Consequently, SDG&E does not expect to implement the new billing format until 2027 at the earliest.

Protests are due April 6.

INSTANT ANALYSIS

This is a transparency-driven billing change, but the significance is political and perceptual, not financial. SDG&E is taking a cost that has long been embedded in bundled rates and surfacing it as a visible line item, which will make PCIA more salient to customers. That matters in a landscape where PCIA remains one of the most contested cost-recovery mechanisms between investor-owned utilities and Community Choice Aggregators.

There is no rate impact or cost reallocation. But by explicitly labeling PCIA on bundled bills, SDG&E aligns bundled customers with the same cost visibility long experienced by departing load customers. That move implicitly reinforces the idea that PCIA is a system obligation tied to past procurement, not a discretionary or avoidable charge.

The delayed implementation timeline is significant. Pushing implementation to 2027 suggests that billing system constraints are real, but it also gives the Commission and stakeholders time to continue debating PCIA reform while the visibility shock is postponed. The memorandum account setup indicates that SDG&E isn't just complying, it's laying groundwork to bill ratepayers for the cost of compliance.

WHO SHOULD CARE?

• CCAs: Breaking out the PCIA on bundled bills makes the charge more visible and easier to scrutinize. While this might fuel anti-PCIA narratives, it also reinforces that the charge applies broadly, not just to CCA customers. Expect this to become a standard ask in every IOU GRC Phase 2 going forward.
• IOUs (SDG&E, SCE, PG&E): The move strengthens the framing of PCIA as a system obligation tied to legacy procurement, not a penalty tied to choice.
• Large C&I customers and Direct Access Entities: The change increases transparency and comparability across customer types and lays the groundwork for future disputes over allocation, vintaging, and exit cost design.
