sonnen, ES Solar Develop Utility Solar Battery Enterprise Program


Blake Richetta

sonnen, a sensible residential energy storage firm, and solar contractor ES Solar are increasing Rocky Mountain Power’s (RMP) Wattsmart Battery Program throughout Utah and, extra not too long ago, into Idaho. As it scales its enterprise improvement group and regional footprint, ES Solar is anticipated to convey as much as 35 MWh of grid-interactive battery capability on-line in 2022 by way of the Wattsmart program.

As it strikes past its proof-of-concept part, ES Solar is experiencing exponential development with over 6 MWh of month-to-month sonnen energy storage gross sales in Utah and Idaho, attributed to the Wattsmart program. In latest years, Rocky Mountain Power has steadily ended its solar internet metering subsidy to shift focus towards changing solar alone with solar + energy storage with the Wattsmart Battery Program, a pro-community and pro-grid enterprise mannequin which different solar contractors have struggled to adapt to. By implementing this new mannequin, ES Solar and sonnen are enabling the renewable energy transition by serving to construct the most important community of utility dispatched sensible residential batteries within the U.S. that’s decreasing the affect of energy challenges and local weather change on society.

The Idaho Public Utilities Commission accepted the Wattsmart program in April 2022, making Idaho the second state to embrace Wattsmart. As the primary Utah contractor to deploy the brand new enterprise mannequin for smarter, extra grid interactive solar + storage adoption, ES Solar has adopted this enlargement with Wattsmart buyer enrollments in Idaho underway, supported by ES Solar’s new gross sales workplace in Idaho Falls. ES Solar hopes to broaden to extra states.

ES Solar will goal present solar homeowners, each inside its buyer base and externally, to retrofit properties with Wattsmart-enrolled batteries. With the addition of a sonnenCore+ energy storage system, particular person home PV programs might be reworked from sources of intermittent and erratic technology to agency dispatchable grid property that present worth to grid operations. The ensuing solar battery networks assist decarbonize the atmosphere and quickly scale the blueprint for changing sure peaking power vegetation.

In the present Wattsmart fleet, RMP has direct management over the battery swarm and might dispatch it on demand to satisfy grid circumstances with every day, dynamic solar time shifting and directed load curtailment, plus frequency response and directed solar grid injection when the grid wants power, versus when it’s sunny. The Wattsmart Program is quickly rising every month, with over 2,000 client batteries enrolled. With this fleet and Utah’s signature 600-unit Virtual Power Plant at Soleil Lofts, it’s presently believed by sonnen that Rocky Mountain Power is instantly controlling extra residential batteries dynamically and each day, than any utility-controlled battery client program within the nation.

ES Solar is devoted to increasing the attain of sonnen’s programs and platform and has been elevated to the position of value-added distributor and Wattsmart flagship solar contractor. In present and new Wattsmart markets, ES Solar will set up reselling channels with different regional solar contractors and replicate their sensible, utility-controlled battery enterprise mannequin all through the business. Furthermore, the ES Solar group is the primary contractor to have entry to sonnen’s latest expertise, the stackable sonnenCore+ System, which ES launched in July 2022.

By championing this mannequin for promoting grid-interactive solar plus utility managed residential batteries and persevering with to embrace Rocky Mountain Power as a strategic accomplice, sonnen and ES Solar proceed to interrupt from conventional contractor ideologies which place batteries solely as instruments for back-up power or off-grid residing and the utility as an adversary. The ES Solar method and the Wattsmart Program show that true energy transition requires collaboration from the grid, the utility, authorities, and the residents of a group.

“The sonnen and ES Solar teams share a vision of solving our growing energy challenges in a meaningful manner by creating a renewable electrified energy system for society’s future that is scalable and effective,” says Blake Richetta, chairman and CEO at sonnen Inc. “As Rocky Mountain Power’s battery program grows, ES Solar is succeeding in overcoming the complex concepts and challenges associated with effectively integrating residential solar + storage into the broader energy system. As this radical model expands into thousands of new homes, so does the use of batteries for the betterment of individuals, society and the environment, which is the ultimate purpose of a solar battery.”

“We’re honored to expand our relationship with sonnen by rapidly increasing the implementation of smart batteries within the Wattsmart program.” states Nic Evans, vp of strategic partnerships at ES Solar. “Our team emphasizes the need for more than just rooftop solar to drive the clean energy transition and we want to do more than lead this transition, we want to empower other contractors to follow in our footsteps. This is now possible with our value-added distributor model and replicable sales and marketing strategy. As we exceed our goals in Utah and expand into new markets, we’re excited to continue our work with sonnen and Rocky Mountain Power.”
