2026 Guide — Updated for current PG&E rate schedules and TOU pricing
Your PG&E bill is high because PG&E's rates in the North Bay are elevated — partly from wildfire-related grid hardening costs passed to ratepayers — combined with summer temperatures that reach 90–98°F and drive AC use through the 4–9 PM peak window. Resilience infrastructure costs have made Santa Rosa's base rates higher than most PG&E service areas. In 2026, PG&E's summer peak rate reached approximately $0.55/kWh between 4–9 PM — a 9% increase from 2025 that makes Santa Rosa's heavy AC season more expensive than ever.

PG&E's standard residential TOU rate plan divides the day into pricing windows based on grid demand. For Santa Rosa customers in 2026, typical rates look like this:
Peak (4–9 PM weekdays): ~$0.45–$0.55/kWh Off-Peak (all other hours): ~$0.25–$0.35/kWh Super Off-Peak (overnight): ~$0.15–$0.22/kWh
With warm wine-country summers, the peak window is exactly when AC demand is highest — creating a situation where you use the most electricity at the most expensive time of day.
On a TOU rate plan, when you use electricity matters as much as how much you use. A household that consumes 800 kWh per month could pay $120 or $220 depending entirely on what time of day that usage occurs.
In Santa Rosa, where warm wine-country summers keeps AC running into the evening hours, most of that usage lands in the peak window — which is why many residents are surprised to see bills that seem disproportionate to their actual consumption.

Santa Rosa experiences seasonal heat spikes in the 90s–100s, and post-wildfire infrastructure costs have contributed to above-average PG&E rate adjustments in the region.
Beyond temperature, several household factors combine to push Santa Rosa bills higher:
Seasonal patterns in your bill data reveal exactly when and why costs spike. Climapp shows you this pattern instantly — for free.
PG&E assigns every residential customer a monthly baseline allowance — a modest amount of electricity at the lowest Tier 1 rate. In Santa Rosa, most households burn through this allowance quickly during summer, triggering Tier 2 and Tier 3 rates that can be 40–80% higher than Tier 1.
This tiered structure means that the marginal cost of each additional kWh rises as you use more — making high-usage months disproportionately expensive compared to moderate months.
Even with flat usage, your bill rises each year — PG&E has raised residential rates approximately 50% since 2021, driven by wildfire mitigation, grid hardening, and CPUC-approved cost recovery (see rate chart above). Understanding your per-kWh rate is essential to projecting future costs.
For many Santa Rosa homeowners, rooftop solar directly addresses the root cause of high bills: it offsets the kWh you would otherwise buy from PG&E at peak or Tier 2/3 rates. Depending on system size and local conditions, solar can reduce monthly electricity costs by 60–100%.
The economics depend on your specific usage, roof orientation, and local generation potential. Climapp's free calculator shows you a personalized solar savings estimate based on your actual bill data — no sales call required.
Santa Rosa PG&E residential customers typically pay $130–$190 per month during the cooler, wetter months (November through April), with summer bills ranging from $200–$320 during the June–October cooling season. The region's wine-country climate is generally more moderate than the Central Valley, but summer heat waves regularly push temperatures to 95–105°F, driving AC use in the inland neighborhoods east of US-101. Post-Tubbs and Kincade fire infrastructure rebuilding has added rate pressure in the Sonoma County region, with PG&E passing through grid hardening costs that affect all Sonoma County customers. Newly rebuilt homes in the fire zone often have modern, energy-efficient construction — but older pre-fire neighborhoods may still carry higher per-square-foot energy loads.
Santa Rosa is served by Sonoma Clean Power (SCP), the community choice aggregator for Sonoma and Mendocino County communities. SCP supplies electricity through PG&E's grid and offers two plans: EverGreen (100% renewable) and CleanStart (default, approximately 75% renewable), with rates comparable to PG&E supply charges. SCP also runs local programs including rebates on heat pump water heaters, EV charger installations, and home battery storage. Income-qualified Santa Rosa residents can access PG&E's CARE and FERA discounts (20–35% off bills). The Sonoma County Community Development Commission administers LIHEAP energy assistance and connects residents to the free Energy Savings Assistance weatherization program. The Santa Rosa Junior College's Sustainability Office also provides energy education resources for the community. Visit sonomacleanpower.org or pge.com/affordablebill to learn more.
Santa Rosa averages approximately 253 sunny days per year, with the sunnier inland neighborhoods receiving meaningfully more irradiance than the foggy coastside areas of Sonoma County. A 6–7 kW system in Santa Rosa generates approximately 9,000–11,500 kWh annually. What makes Santa Rosa's solar calculus unique is the wildfire and PSPS risk factor: Sonoma County is in a High Fire Threat District, and PG&E has issued Public Safety Power Shutoffs affecting Santa Rosa neighborhoods multiple times in recent years. A solar-plus-battery system provides both bill savings under normal conditions and critical backup power during PSPS events — a meaningful resilience benefit given the region's fire risk history. The California Self-Generation Incentive Program (SGIP) prioritizes battery storage rebates for households in High Fire Threat Districts, and Sonoma Clean Power has facilitated local incentive stacking.
