If you live in Frankfurt, Germany and have solar panels on your roof, you might be able to generate enough energy to power your whole home throughout the day. But if you pull in too much energy for your needs, or not enough, you can trade power with another solar-powered home in Hamburg, or Berlin, or anywhere in the country. That’s the principle behind sonnenCommunity , a nationwide, cloud-based virtual power plant launched around three years ago and made up of around 8,000 homes equipped with solar panels and an interconnected SonnenBatterie—an energy storage unit developed in 2010 by the German company Sonnen . “What’s happening in Germany with peer-to-peer power-sharing is something that’s talked about in the U.S. as a great idea for future energy-storage solutions ,” says Blake Richetta, VP of sales for Sonnen U.S.

The sonnenCommunitie facilitates its energy transfers using the grid infrastructure that already exists in the country, “What we do in Germany is we essentially cut out the middleman—the utility–and we work directly with the grid operator,” Richetta says. Generally, regional utility companies manage the sale, distribution, and flow of energy through the grid and into homes throughout the region in which it operates. But because Germany has just one interconnected grid system, Sonnen is able to bypass the various regional utilities and work with the grid operator to manage the energy flow into and out of homes connected in the sonnenCommunitie, essentially acting as a nationwide utility for its customers.

That’s all well and good for Germany (and Italy, where there’s a smaller sonnenCommunitie), but establishing a sonnenCommunitie in the U.S. would not be quite so easy. There’s just one grid infrastructure, built after World War II, for all of Germany. The U.S.’s grid system, on the other hand, is made up of a complicated network of independent system operators at the state level, nestled within larger regional transmission organizations. Because sending energy across state lines counts as interstate commerce, that has to be overseen by the federal government. And because most areas of the U.S. are regulated markets, meaning a single utility has a monopoly on the region, they can’t just be cut out of the equation, as they are in Germany. Almost needless to say, a U.S.-wide sonnenCommunitie would be a logistical nightmare.

While individual homeowners in the U.S. have installed Sonnen solar arrays, complete with batteries, they have not been able to be aggregated into a solar-sharing network. But this fall, Sonnen is launching the first sonnenCommunitiy in the country. It will, necessary, look very different from its German counterpart, but it’ll be no less innovative.

Mandalay Homes, an Arizona-based home builder, is in the process of building a 2,900-home community in Prescott, Arizona. In that development, which will be called Jasper, all of the homes will be outfitted with solar tiles and 8-kilowatt-hour SonnenBatteries. When it’s complete, the Jasper sonnenCommunity will create a virtual power plant that will be able to aggregate up to 16 megawatt-hours of solar energy and deploy 8 MWh at any given time–comparable to a small power plant.

“What we had to do was partner with a specific utility, plus, we had to partner with a specific homebuilder,” Richetta says. If Sonnen were to try to launch a peer-to-peer community in the U.S. in the same way it did in Germany, with individual homeowners installing solar panels and batteries, and opting into the sonnenCommunitie, it would be a mess, Richetta says. “We might get two units in one utility’s territory, three in a different utility’s territory, and five in another,” he adds. “It would be difficult to control the launch of the community.”

Instead, Sonnen consulted with Mandalay Homes to standardize the integration of the Sonnen solar array across the units in the development. “So then we’re able to go to the utility and say: ‘Look, we have 8 MWh of clean energy available—are you interested in using it?’ And if they say yes, we can start to make the case around this type of sonnenCommunity in the U.S.,” Richetta says.
