*ENERGY $AVER helps you cut your utility bill by shifting when you run energy-hungry appliances to the cheapest off-peak hours.** If you're on a Time-of-Use (TOU) electricity plan, the price you pay per kWh changes throughout the day — peak hours cost the most, and off-peak hours cost a fraction of that. ENERGY $AVER makes it easy to see those rates in real time and plan your appliance usage around them, so you keep more money in your pocket every month. **HOW IT WORKS** • Enter your ZIP code or scan your utility bill to load your local TOU rate schedule. • ENERGY $AVER pulls real-time peak, mid-peak, and off-peak rates for your area. • Use the 7-device planner to schedule appliances like your AC, water heater, dishwasher, EV charger, washer/dryer, pool pump, and more for the cheapest hours. • See your projected monthly savings update instantly as you adjust each device. **KEY FEATURES** **Live Rate Dashboard** See your current rate at a glance, whether you're in peak, mid-peak, or off-peak, plus a countdown to the next rate change so you always know when to run — and when to wait. **Smart Device Planner** Schedule up to 7 common household appliances. Set AC and water heater temperatures in Fahrenheit, choose runtimes, and let ENERGY $AVER calculate your savings based on your actual rate plan. **Savings Tracking** Watch your daily and monthly savings add up. See how much peak kWh you've avoided and the dollar value of every shift you make. **Peak Alerts** Get notified before peak hours begin and when off-peak windows open, so you never miss a chance to save. **Optimize Roadmap** Get personalized recommendations for smart-home upgrades — like smart thermostats, timers, and EV chargers — with break-even estimates and potential savings. **Shop** Browse curated, energy-saving products and partner offers, with referral incentives to help you save even more. **SUPPORTED UTILITIES** ENERGY $AVER supports the major utilities — SCE, PG&E, SDG&E, and LADWP — plus a generic fallback for 300+ ZIP codes. Rates are pulled from your bill and public TOU schedules. **PRIVACY FIRST** No account required. Your data stays on your device. ENERGY $AVER doesn't sell your information, and you can delete everything at any time. **IMPORTANT NOTE** ENERGY $AVER is not affiliated with any utility company. Rates are estimated from public TOU schedules and your bill and may vary. Always confirm current rates with your utility provider.
