As part of Mandalay Homes’ Discovery Home concept for production homes, the company will install sonnen’s energy storage systems at 2,900 homes at its Jasper planned community in Prescott Valley, AZ. The 23 megawatt hours of energy storage installed will serve as a hive of energy storage along with the rooftop solar installed on the homes that’s branded as sonnenCommunity, creating a virtual power plant (VPP).
"Mandalay and Arizona Eco-Development have partnered to deploy a radical new residential master community design topology including clean energy generation, self-sufficiency and self-consumption via a smart energy storage system in combination with an efficient load profile and a sealed home, all anchored on intelligent grid interaction," said Blake Richetta, sonnen's senior vice president and head of its US subsidiary.
The German company, sonnen, said the system is on a scale that hasn’t been seen before for residential energy storage in a planned community. The community also hopes to contribute to decommissioning an aging coal-fired power plant in Northern Arizona in the next three years. Already the carbon neutral project has received multiple awards for innovation and energy efficiency technologies.
"The Mandalay sonnenCommunity concept for Jasper, as well as for other Mandalay communities like Wickenburg Ranch and Timber Sky in Flagstaff, serve to inspire leaders in homebuilding to build zero-net-energy homes with solar, energy storage and other energy efficient design concepts, creating the energy efficient home of the future,” said Dave Everson, CEO and founder of Mandalay Homes.
The community’s eco-homes and their energy storage systems will act as an intelligent network forming the VPP that can interact with the electric grid to increase grid efficiency and lower operating costs, sonnet said. The project aims to flatten the energy load curve of the community, minimize local grid stress and reduce its carbon footprint to the minimum possible. The system also allows it to rely on thousands of distributed energy resources to make it largely immune to power blackouts.
"Jasper community represents the single most significant innovation in how new homes can contribute to the decarbonization of our electricity grid. The 2,900 homes in which the sonnenCommunity will be deployed in Prescott Valley represent a true clean energy revolution, setting a new standard in energy efficient communities that will challenge the status-quo associated with the US electricity grid,” Richetta asserted.
The energy storage systems store excess energy generated by rooftop solar in the daytime. Then it releases the energy when needed in the evening, a process called solar time shifting. The system also will pull energy from the grid between 2 and 5 am, using excess energy produced by a nuclear baseload power plant. The batteries also will absorb excess energy from the solar energy produced by solar power in Arizona between 10 am and 2 pm. By absorbing energy when it’s most abundant it helps reduce stress on the grid and makes it less expensive for homeowners in the community.Tweet
