Understanding Time-of-Use Rates
PG&E charges different rates throughout the day. Peak rates (4-9 PM) can be 2-3x off-peak rates. Strategic HVAC operation saves money.
Available Rate Plans
E-TOU-C is default for most. E-TOU-D suits all-electric homes. E-ELEC (new) optimizes for electrification. EV rates work for some configurations.
Pre-Cooling/Pre-Heating Strategies
Cool your home before 4 PM peak pricing starts. Let temperature drift slightly during peak hours. Resume normal operation after 9 PM.
Smart Thermostat Integration
Many smart thermostats integrate with utility rates to automate cost optimization. Set your comfort limits and let automation handle timing.
Solar Rate Considerations
With solar, net metering provides credits during production hours. This may change optimal operation timing—consult your specific situation.
Comparing Your Options
PG&E's comparison tool shows estimated costs under different plans. Run it with your actual usage data for accurate comparison.
