PG&E Residential Rates Could Drop 4.5%

Energy and Environmental Economics released a study on May 7, 2026 funded by Powering America’s Commercial Transportation and the Edison Electric Institute concluding that medium- and heavy-duty truck fleet electrification can put neutral-to-downward pressure on residential rates by 2035, with managed off-peak charging cutting PG&E system rates by 4.4 to 4.5 percent and saving a typical 600 kWh-per-month customer $15 to $20 per year. Georgia Power customers would save $1.00 to $1.10 per year by 2035 under the same managed-charging scenario.

The Data

The white paper, titled Electric Rate Impacts of Medium and Heavy Duty Vehicle Electrification Investments, modeled rate impacts for PG&E in California and Georgia Power across two scenarios in 2028 and 2035. Managed charging — defined as fleet operators avoiding peak demand windows — drives the larger residential reduction because new sales spread fixed grid costs without forcing peak generation. Unmanaged charging produces a smaller benefit but does not raise rates above the no-electrification baseline. Sam Vercellotti, PACT policy adviser, stated that timing and certainty of fleet electrification are factors in its rate effect, framing managed charging as a regulatory design choice, not a market default.

Why It Matters

Critics of fleet electrification have argued that adding industrial truck loads will push residential bills higher. The E3 model — using regulator-backed cost-allocation methodology — produces the opposite finding when smart-tariff design and managed charging are in place. The reduction lever sits with state utility commissions: time-of-use rates for medium- and heavy-duty fleet customers, subscription or grid-access charges, and active load management baked into integrated system planning. The study’s recommendations also call for siting charging infrastructure where existing capacity has headroom and using flexible interconnection so fleet upgrades do not block other customer projects.

The Gap

The study models PG&E and Georgia Power, two utilities with very different rate structures and fleet density. PG&E has the highest US residential retail rates and a state mandate driving heavy-duty electrification; Georgia Power’s smaller benefit reflects lower starting rates. Whether the result holds in MISO or SPP territories — where industrial rates are already low — remains untested. The study also assumes managed-charging participation high enough to shift load profiles materially. Without binding tariffs, fleets may charge whenever it suits operations, eroding the modeled savings.

Critical Perspective

EEI is the trade association for investor-owned utilities, and PACT is a coalition that lobbies for commercial-vehicle electrification — both have a direct interest in framing fleet electrification as ratepayer-friendly. The study uses regulator-backed methodology but is not a regulatory filing. State commissions evaluating cost-allocation rules should treat the findings as one input alongside utility planning data and independent third-party reviews.
