PG&E energy bills spike 18% in December as Bay Area temperatures plummet, here’s how residents can cut costs before January arrives

PG&E energy bills spike 18% in December as Bay Area cold temperatures drive power demand higher than last year. Residents opening their utility bills face shocking increases as frigid winter weather and rising natural gas prices nationally combine to squeeze household budgets. Here’s what you need to know about staying warm without breaking the bank.

What’s Driving the December Energy Bill Spike

The Bay Area is experiencing unusually frigid conditions this December compared to last year. A weather phenomenon called radiation fog is trapping cold air and preventing temperatures from rising during the day. When customers see their thermostats reading colder than expected, they naturally turn up their heating systems earlier and run them longer than they did in prior winters.

According to Megan McFarland from PG&E, “Whenever we have cold snaps, customers use their heat more, their houses are cold.” Bay Area residents report that they started activating their heating systems sooner this December compared to last year. The combination of below-average temperatures and extended heating use has created the perfect storm for rising utility costs.

National natural gas prices have climbed significantly as well, affecting wholesale energy costs that PG&E passes through to customers. This widespread price increase compounds the local impact of cold weather, making December particularly expensive for heating.

Real Customer Bills Show the Dramatic Impact

Billing Factor	Details
Typical December Bill Increase	Estimated 18% higher than last December
Real Customer Example	One Novato resident reported expecting bill near $400
Primary Cost Driver	Natural gas for heating as temperatures drop
Efficiency Savings Opportunity	Lower thermostat 1 degree = save 1% on bill

Many Bay Area residents have already experienced bill shock when opening their December statements. One customer reported expecting a bill of approximately $400 this month, significantly higher than typical winter months. Others noted that electricity rates increased 26% per kilowatt-hour in the Bay Area, even beyond the standard rate structure.

Homeowners with solar panels have not been immune to the increases. Persistent radiation fog has reduced solar generation just when cold weather increases heating demand. This double impact means solar customers face higher bills despite their renewable energy investments.

“It’s frigid, very cold, I don’t remember it being this cold before. Brace yourself when you open that PG&E bill.”

Energy Efficiency Tips to Lower Your Winter Bills

PG&E recommends that customers prioritize thermostat management as the single most effective way to reduce winter bills. Lowering your thermostat by just one degree saves approximately 1% on your total energy bill. Setting thermostats to 68-70 degrees during the day and lower at night maximizes savings while maintaining reasonable comfort.

Beyond thermostat adjustment, weatherstripping around windows and doors prevents cold air from entering your home. Replacing furnace filters regularly ensures heating systems operate efficiently. Both tasks take minimal time but deliver significant energy savings. The Bay Area Regional Energy Network also recommends checking heater filters monthly during cold months to maintain peak efficiency.

One critical warning: PG&E advises against relying heavily on gas fireplaces for heat, as these consume energy rapidly and create additional utility charges. Electric heaters similarly increase bills substantially compared to efficient thermostat management.

Assistance Programs Available for Qualifying Households

PG&E’s Family Electric Rate Assistance Program (FERA) provides monthly discounts on both electric and gas bills for qualified low and moderate-income households. The program recently expanded eligibility to include one and two-person households, making approximately 150,000 additional customers eligible for 18% electric discounts.

Beyond PG&E, the Bay Area Regional Energy Network offers the EASE program to fund weatherization improvements for qualifying homeowners. The agency sends energy experts to homes at no cost to assess eligibility for upgrades like insulation, air sealing, and heating system improvements. These long-term fixes help reduce bills for years to come.

Low and moderate-income residents should check both programs to see if they qualify. The financial relief can offset a significant portion of December’s unexpected billing increases.

Are High Winter Heating Bills the New Normal for California?

California’s unusual weather patterns and rising natural gas prices suggest that high winter bills may continue. The U.S. Energy Information Administration forecasts that national electric prices will increase through 2026, outpacing inflation. However, PG&E residential electric rates decreased in September 2025 and are expected to drop again in 2026, providing some relief on the electric portion of bills.

Natural gas prices remain more volatile and dependent on national market conditions. Bay Area residents should prepare for continued expense during winter months, but the long-term outlook includes rate decreases for electricity. Installing efficient heating systems, improving insulation, and enrolling in assistance programs offer the best strategy for managing costs in coming winters.
