An SDG&E household considering a solar-plus-battery PPA should include the Power Charge Indifference Adjustment, or PCIA, in its utility-bill review. It is not a charge from the rooftop solar provider. Understanding where it appears helps you compare a qualifying no-upfront offer with the electricity costs that remain after installation.
This is especially useful if your bill lists San Diego Community Power for generation service and SDG&E for delivery.
What does PCIA pay for?
SDG&E's community-choice FAQ explains that PCIA recovers costs associated with older long-term energy contracts entered into on customers' behalf. Those obligations continue when customers move to a community choice provider for electricity generation.
SDG&E says customers receiving its generation service also pay these costs within generation charges. PCIA should therefore not be treated as a new rooftop-solar fee or assumed to disappear simply by changing generation providers.
For community-choice customers, SDG&E identifies a PCIA vintage associated with the year the CCA began providing generation service in the city. The vintage remains the same, but its charge can change annually. Ask your provider to identify the applicable vintage and current tariff in the estimate rather than reuse an old quote's rate.
Find it in the correct part of your bill
San Diego Community Power's FAQ explains the presentation: for its customers, PCIA appears separately within SDG&E electric delivery charges. For customers receiving SDG&E generation, it is embedded in generation rates and shown in the breakdown of current charges.
Community Power's bill-reading guide also explains the generation credit that removes SDG&E's generation charge when Community Power supplies that service. That credit is different from rooftop-solar export compensation.
A practical review is to mark each bill component once:
- SDG&E delivery charges and the applicable PCIA treatment.
- Your actual generation provider's charges and credits.
- Remaining taxes, fees and fixed charges.
- The separate proposed PPA and any battery payments.
Do not add PCIA again if the comparison already includes it in a combined rate or bill subtotal. Conversely, a generation-only price is not the entire utility cost.
Ask how the solar model treats the charge
For Solar Billing Plan customers, SDG&E explains that a CCA sets generation import prices and generation export credits. The model should use the customer's actual provider and applicable solar billing arrangement, including existing NEM rules where relevant.
Ask the quote preparer to show the tariff-based calculation of PCIA alongside projected imports and credits. Avoid assuming that every exported kilowatt-hour cancels every charge, or that annual solar production equal to annual use produces a zero utility bill.
For example, suppose two proposals show the same PPA payment and generation-service estimate, but only one includes the applicable PCIA in remaining utility costs. They are not yet comparable. Request matching assumptions before judging which proposal better fits your home. No particular PCIA amount or savings is assumed here.
Put battery benefits and PPA payments together
A battery can shift suitable daytime solar into later household use. Ask the design to balance that use with your preferred outage reserve. Backup remains limited by available charge, supported loads and equipment; solar recharge requires sunlight and compatible operation.
A qualifying no-upfront PPA can provide access to a professionally installed system without an upfront equipment purchase. The CPUC solar guide explains provider ownership and ongoing electricity payments. Confirm eligibility, price, any escalator, term, battery ownership and charges, maintenance and home-sale transfer terms. No upfront purchase does not mean free electricity or guaranteed savings.
