Utah Rocky Mountain Power TOU rates start 12/1/2025. Save with home battery load shifting—charge off-peak, run on-peak—and get backup power.
Are you a Rocky Mountain Power customer in Utah? The new Time of Use (TOU) rate structure, available as of 12/1/2025, is your chance to turn high energy prices into major savings with a home battery storage system!
The TOU rate charges significantly more for electricity during specific "On-Peak" hours—when demand is highest—and much less during "Off-Peak" times. Your home battery is the key to minimizing what you pay for power.
How Your Energy Storage System Saves You Money
A residential battery automatically manages your home's energy flow, utilizing the low-cost Off-Peak hours to your advantage—a strategy called Load Shifting.
The battery will charge when electricity is cheapest and discharge to power your home when rates are highest, ensuring you avoid the expensive peak charges!

Example Savings with Load Shifting
Imagine your home uses 10 kWh of power during the expensive On-Peak hours (6 PM - 10 PM) in July:

|---|---|---|
| Without Storage | 32.0834¢ | $3.21 |

Reliable Backup Power: Peace of Mind Included
Beyond daily savings, your energy storage system provides essential security for your family.
When a storm or grid failure causes a power outage, your battery instantly and seamlessly takes over, providing power to your critical appliances, lights, and devices. You maintain comfort and access to vital functions while your neighbors are in the dark.
