sonnenCommunity is a peer-to-peer energy-sharing solution which has been live in Germany (with a small expansion in Italy) for over three years. The nationwide, cloud-based, virtual power plant is comprised of around 8,000 homes with storage panels and a sonnenBatterie and has been growing rapidly. With their recent announcement of an American sonnenCommunity and rapid expansion of sonnen in Australia (including their sonnenFlat flat rate electricity offering), how long will it be until we see the service in Australia?
According to the official site, it’s a ‘community of sonnenBatterie owners who are committed to a cleaner and fairer energy future’. The site has a live widget showing the feed-in for the last 12 months, which was showing almost 15 million kWh and the grid consumption, which was a little over 8 million. This means the prevention of almost 9 million tonnes of co2. Amazing statistics!
We’ve also embedded a video below about the service – give it a watch and let us know in the comments if you have any questions.
sonnenCommunity in Arizona, USA
sonnen announced a partnership with Mandalay Homes this week, which will bring their ‘Clean Energy Communities’ initiative to 3,000 homes in Arizona. This will mean the deployment of over 10GW of solar panels and 11.6MW of battery storage systems in the ‘Jasper’ community in Prescott Valley.
As America has many different grids and operators, the homes will be connected to local utility Arizona Public Service (APS). The systems will trade electricity between themselves and will try to minimise flow back into the APS grid and maximise the amount of power bought from the sonnenCommunity in peak times (3-8pm). When required, the sonnenBatteries will recharge from the grid during off-peak times (2-5am).
sonnen Director of Business Development Olaf Flohr estimated in PV Magazine that the system will allow Jasper residents to be 75-80% energy independent and that bills will be around $24 USD per month.
sonnenCommunity in Australia
sonnenCommunity was easier to launch in Germany because they have one interconnected grid system – which means sonnen was able to cut out the utility companies and work directly with the grid operator to launch their service.
Usually, a regional utility company will manage the sale, distribution, and energy movements through the grid. It’ll be interesting to see how sonnenCommunity fares in America – this ‘trial run’ will see how much opportunity there is to expand in areas such as Australia.
Given the fact that Australia is a world leader when it comes to household solar installations, it’d make sense to bring the service over here. Watch this space!
