AutoGrid, Sonnen pair smart energy storage with DA

Virtual power plant, DR, DER controls offer lots of options

"Energy internet" technology firm AutoGrid Systems teamed with smart energy storage systems firm Sonnen (subsidiary of SonnenBatterie) to fully integrate AutoGrid's flexibility management application suite, AutoGrid Flex, with Sonnen's residential and commercial energy storage technology, AutoGrid said yesterday. The two firms will help energy-project developers, utilities and other energy service providers better manage, optimize and aggregate SonnenBatterie systems and other DER, it added.

"Sonnen's advanced battery storage systems are already accelerating the world's transition to a more distributed, renewable-friendly energy grid," said AutoGrid CEO Dr Amit Narayan in prepared remarks. "By providing a platform that enables energy service providers to more easily aggregate these distributed storage systems, we will further accelerate this transformation.

"Our new partnership with Sonnen will combine AutoGrid Flex software with Sonnen's intelligent battery storage systems, delivering higher project ROI to energy-project developers and utilities who are seeking to deploy and manage fleets of DERs."

AutoGrid Flex provides advanced forecasting, real-time controls and scalable architecture to manage large numbers of distributed SonnenBatterie systems in combination with other DER, AutoGrid said. Fleet management is key to optimizing the use of battery storage capacity for both the local site and the regional grid network, and AutoGrid Flex is already integrated with multiple wholesale markets, including Cal-ISO, PJM and ERCOT – and underpins several of the world's leading utility DER systems, it added.

"By integrating our technologies in the US market, Sonnen and AutoGrid provide a solution that elegantly and intelligently manages DERs, including grid-connected SonnenBatterie systems, maximizing return-on-asset, reducing project delivery time and unlocking new revenue streams for utilities, energy project developers and energy managers," said Sonnen CEO Christoph Ostermann in prepared remarks.

QUOTABLE: In Germany, we have seen the value the virtual power plant model provides in balancing energy supply and demand by aggregating our SonnenBatterie systems. By adding AutoGrid Flex's ability to optimize DER assets in support of grid services and wholesale energy programs for the US market, our smart SonnenBatterie energy management systems will accelerate the adoption of a smarter, cleaner utility grid by reducing integration costs, improving ROI and increasing the use of DERs. – Sonnen CEO Christoph Ostermann in prepared remarks

Designed to optimize all DER asset categories including DG, battery storage and DR resources, AutoGrid Flex provides out-of-the-box support for all prevalent grid services and wholesale market programs spanning all customer segments – residential, commercial and industrial – through its three main applications:

  • A DR optimization and management system (DROMS) – an enterprise-grade DR management system;
  • DER management system (DERMS) for providing targeted, distribution-level grid-services, and
  • Virtual power plant (VPP) for participation in wholesale markets, the firm said.

Sonnen launched its SonnenBatterie Eco Compact, a residential energy-storage system in July (SGT, July-8) after announcing its plans in November (SGT, Nov-30). GE Ventures became an investor in Sonnen in June, calling it Europe's largest maker of residential lithium storage systems and operator of Europe's first online energy-sharing platform (SGT, June-7).
