Rocky Mountain Power Wattsmart Battery Program
Leverage incentives to reduce your cost to acquire backup power.
Rocky Mountain Power’s Wattsmart program offer financial incentives to homeowners and businesses who install battery storage systems in their territory. Homeowners can receive $400/kW with a cap of $2,000 per household. Businesses can receive up to $500/kW. The incentive is based on the continuous power level of the inverter. Prior to the $2,000, Fortress Power’s Envy 12kW inverter provided the highest incentive in the Wattsmart program.
In addition to the upfront incentive, participants receive an annual bill credit of $15/kW, starting in year two. That’s a $180 credit for the Envy 12kW Inverter.
Wattsmart aims to promote renewable energy adoption and enhance grid reliability by using clean, renewable energy stored in battery systems instead of traditional power plants. Rocky Mountain Power generally calls on participants’ battery storage system for five minutes instead of calling on expensive, less efficient gas peaker plants. Meanwhile, your battery storage system may serve as back-up electricity to your home or business, in case you ever need it. By participating, you will earn an upfront enrollment incentive and ongoing bill credits while helping to keep electricity prices in the region among the nation’s lowest.
