New Joint Venture to Spur DERs

Siemens and AES are joining forces to form to a new joint venture called Fluence, a move likely to spur greater uptake of energy storage and other distributed energy resources.

Siemens and AES Corporation have agreed to form a new global energy storage technology and services company under the name Fluence.The joint venture will bring together AES’ decade of energy storage deployment experience in seven countries, with Siemens’ century of global leadership across energy technology products and services.

With a focus on scalable, flexible and cost-competitive energy storage solutions, the AES Advancion and Siemens Siestorage energy storage platforms will be complemented by the additional of expanded services, whereby Fluence will offer customers a wider variety of options to meet the challenges of a rapidly transforming energy landscape.

Siemens and AES will have joint control of the company with each holding a 50% stake. Fluence’s global headquarters will be located in the Washington, D.C. area with additional offices located in Erlangen, Germany, and select cities worldwide. The transaction is expected to close in the fourth quarter of calendar year 2017, subject to regulatory and other approvals.

Fluence will operate independently of its parent companies, combining the robust capabilities and expertise from Siemens’ battery-based energy storage solutions group under the Energy Management division with AES’ subsidiary, AES Energy Storage. 

AES and Siemens are currently ranked among the leading energy storage integrators worldwide by Navigant Research. Together, the two companies have deployed or have been awarded 48 projects totaling 463 MW of battery-based energy storage across 13 countries, including the world’s largest lithium-ion battery-based energy storage project near San Diego, California.

“As the energy storage market expands, customers face the challenge of finding a trusted technology partner with an appropriate portfolio and a profound knowledge of the power sector. Fluence will fill this major gap in the market. With the global reach of an experienced international sales force as well as Siemens’ leading technology platform Siestorage at its disposal, Fluence will be perfectly equipped to serve this very interesting market,” said Ralf Christian, CEO of Siemens’ Energy Management Division.

“Over the past 10 years, AES has become a global leader in utility-scale, battery-based energy storage. Today, AES’ Advancion platform is present in seven countries with more than 200 MW of energy storage deployed, including the largest installed system of its kind in the world,” said Andrés Gluski, AES president and CEO. “Partnering with Siemens to form Fluence will offer both large and small customers the full gamut of proven, state-of-the-art energy storage solutions in over 160 countries. This will accelerate the integration of renewables into the energy network of tomorrow.”

The grid-connected energy storage sector is expected to expand from a total installed capacity of 3 GW at the end of 2016 to 28 GW by 2022 according to IHS Markit, which is equivalent to the power used by 18.6 million households. By incorporating energy storage across the electric power network, utilities and communities around the world will optimize their infrastructure investments, increase network flexibility and resiliency, and accelerate cost-effective integration of renewable electricity generation.

The AES Advancion and Siemens Siestorage technology platforms each support numerous energy storage applications. 

The goal for fluence is to provide a full suite of energy storage solutions across a diverse customer base.
