Gas vs. electric driving costs · adjust vehicle and price period below
Why is it like this in Rhode Island?
Rhode Island's residential electricity rates of about 28.4¢/kWh place it among the most expensive states for home electricity, for the same structural reasons that affect the rest of New England. Gas prices are near the regional average. Through 2024 and early 2026, the result was one of the more pronounced gas-over-electric cost advantages in the country — driving on gasoline cost meaningfully less per mile than charging. The Iran conflict has temporarily flipped that: at conflict-elevated gas prices, electricity is now the cheaper per-mile option. At pre-conflict baseline prices, gasoline holds a clear advantage.

Rhode Island's PUC approved a 16% jump in Rhode Island Energy's winter supply rate, adding $22.28/month to average bills from October 2025 — pushing Rhode Island's already sky-high electricity rates (~28–37¢/kWh seasonally) further above gasoline's per-mile cost and reinforcing gas as the cheaper fuel for PHEV drivers.
Rhode Island Energy filed for additional base-rate increases — including a $7.78/month average electric hike — on top of volatile seasonal supply charges, signaling that Rhode Island's structural electricity costs will continue rising well into 2026.
Rhode Island regulators rejected a large share of Rhode Island Energy's infrastructure spending plan in response to mounting ratepayer anger over some of the highest electricity prices in the continental U.S. — context that explains why even modest capital spending cuts are closely watched by PHEV owners who depend on the electric-mode cost calculation.
