September 5, 2019: US utility Rocky Mountain Power revealed what it says is the largest residential battery demand response solution in the US on August 28, a solar-powered storage system using batteries by Sonnen.
The Wasatch Group property management company, Rocky Mountain Power, solar company Auric Energy and Sonnen have joined forces to install and operate the virtual power plant at the Soleil Lofts apartment community in Herriman, Utah.
The project will use more than 600 individual Sonnen ecoLinx batteries with 12.6MW of storage capacity to provide emergency back-up power, and peak energy use management.
“The combination of solar and long lasting, safe, intelligent energy storage managed by the local utility is an essential component to the clean energy grid of the future,” said Sonnen chairman and CEO Blake Richetta.
“The solar industry should find inspiration in this extraordinary project, as it provides a blueprint for the future of grid-optimized battery storage.”
The Soleil Lofts apartment complex is not yet inhabited — residents will begin to move in from this month, and the final building should be completed by December 2020.
Once that happens, the complex will be the largest fully installed, operational residential battery demand response solution in the US, the conglomerate says.
