Fluence Energy, an energy storage technology and services company jointly owned by Siemens and The AES Corporation, announced it will supply the world’s largest lithium-ion battery-based storage project, a 100MW/400MWh (four-hour duration) installation in Long Beach, California.

Bringing together the people, technology and customers of AES Energy Storage and Siemens’ energy storage team, Fluence builds on more than a decade of grid-scale battery-based energy storage experience and the largest advanced battery-based energy storage fleet in the world with nearly 500MW deployed or awarded across 15 countries.

The company has also announced a new and ongoing sales partnership through which the Siemens global sales force will market and sell Fluence energy storage systems, including Siestorage, Advancion, and the newest Fluence platform, SunFlex Energy Storage for solar PV.

This new partnership provides Fluence with a global sales presence in 160 countries from a trusted supplier to thousands of utilities, power developers and large commercial customers, while giving Siemens access to the most proven and widely deployed grid storage technology platforms.

“We continue to believe in and deliver on the promise of energy storage to reduce costs, improve power systems, and create a more sustainable future,” said Stephen Coughlin, president and CEO of Fluence.

“However, we saw customers struggling to find a trusted technology partner with deep knowledge of the power sector and the ability to deliver an industrial grade solution they could count on to be there in the future. With a team drawn from both Siemens and AES, we are fluent in the power sector and bring the
capabilities, global reach and experience to make sure our customers achieve the full value of storage.”

The 100MW/400MWh Alamitos contract adds to the set of projects Fluence will support (directly or indirectly), including:

  • 40MW of new four-hour storage and 37.5MW of existing four-hour storage for San Diego Gas & Electric, including the largest lithium-ion battery energy storage installation in North America, providing key capacity for reliability in southern California;
  • A microgrid project for Italian energy utility Enel on the Mediterranean island of Ventotene, where battery storage is helping reduce fuel use, costs and emissions on the island’s network;
  • Three projects adding much needed reliability for Arizona Public Service’s distribution grid in areas with high solar penetration – including one that will take the place of rebuilding about 30km of transmission and distribution poles and wires;
  • Six energy storage projects being installed across Germany, providing key frequency regulation (primary control resource) services for grid stabilization; and
  • Two 10MW projects in the Dominican Republic for AES Dominicana that added critical resilience for the island’s grid during last September’s hurricanes.
