French energy company Engie is deepening its collaboration with tech giant Google in Germany. Originally launched in 2021 to provide 24/7 decarbonized energy, the partnership is now being expanded to include battery storage solutions and new renewable power purchase agreements (PPAs), aimed at enhancing electricity system flexibility and grid stability.

Under the agreement, Engie will continue to act as Google’s decarbonized energy manager in Germany, leveraging its expertise in energy management and optimization. The goal is to deliver green electricity on an hourly basis from new onshore wind and solar projects, supplemented by storage capacity, while also integrating volumes from Google’s existing long-term PPAs with third-party suppliers.

To offset the intermittency of renewable generation, the plan incorporates battery energy storage systems (BESS) and pumped-storage hydroelectric plants in Germany. This combination is expected to provide a more precise balance between supply and demand, enabling Google’s German operations to achieve approximately 85% decarbonized energy by 2026.

The announcement comes amid Google’s significant investments in Germany, with the company planning around €5.5 billion in artificial intelligence infrastructure and office facilities between 2026 and 2029.

Voltwise: Extend German grid fee exemption for large batteries to 2034 Germany's Federal Network Agency is consulting on a proposed overhaul of its grid fees to introduce a General Grid-Fee System (AgNES). Battery energy storage systems (BESS) are currently exempt from the charges and Voltwise's head of German operations, Thorsten Klöpper, is suggesting a three-stage system which takes account of battery-related grid benefits.

Opinion & Analysis

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.

Opinion & Analysis

When will there be nationwide financing solutions for battery storage systems in Germany? The use of battery storage systems is essential for the success of the energy transition and the best possible use of renewable energies, but also for being able to temporarily store surplus energy from other sources. Technically, there are already solutions for all possible sizes of battery storage systems, from private home storage systems to large-scale storage systems with a capacity of more than 50 MWh. But what about the financing of battery storage systems, is it already offered as standard?
