Europe’s largest energy storage system is now live at the the Johan Cruijff Arena


Amsterdam (29 June 2018) - Today the largest European energy storage system using second-life and new electric vehicle batteries in a commercial building was made live. Amsterdam Alderman Udo Kock conducted the official opening ceremony.

This unique project is the result of collaboration between Nissan, Eaton, BAM, The Mobility House and the Johan Cruijff ArenA, supported by the Amsterdam Climate and Energy Fund (AKEF) and Interreg.

The 3 megawatt storage system provides a more reliable and efficient energy supply and usage for the stadium, its visitors, neighbors and the Dutch energy grid. Combining Eaton power conversion units and the equivalent of 148 Nissan LEAF batteries, the energy storage system not only enables a more sustainable energy system, it also creates a circular economy for electric vehicle batteries.

“Thanks to this energy storage system, the stadium will be able to use its own sustainable energy more intelligently and, as Amsterdam Energy ArenA BV, it can trade in the batteries’ available storage capacity.” says Henk van Raan, director of innovation at the Johan Cruijff ArenA. “The ArenA is assured of a considerable amount of power, even during an outage. As a result, the stadium will contribute to a stable Dutch energy grid. The Johan Cruijff ArenA is one of the most sustainable stadiums in the world and leads the way in introducing smart innovations like this unique energy storage system.”

“We are delighted to be part of the Europe’s largest energy storage system developed for a commercial building. Thanks to the Johan Cruijff Arena we can demonstrate today that re-purposing the batteries of Nissan electric vehicles can contribute to make the whole energy system more efficient and sustainable. We are putting our electric ecosystem at the heart of a sustainable future, transforming the way we drive and also transforming the way we live’ says Francisco Carranza, Managing Director of Nissan Energy.

Flexible storage capacity

The energy storage system plays an important role in balancing supply and demand of energy in the Johan Cruijff ArenA. The storage system with 3 megawatts and 2.8 - megawatts hour is enough to power several thousand households. This capacity also means that the energy produced by the 4,200 solar panels on the roof of the ArenA can also be stored and used optimally. The energy storage system will provide back-up power, reducing the use of diesel generators, and provide relief to the energy grid by flattening the peaks that occur during concerts...

I don't see how Nissan can make that claim of "largest", though:

What’s Possible For Used EV Batteries? Daimler Energy Storage Units Provide Second Life Power


Like most consumables in today’s world, batteries from electric and hybrid vehicles have a tipping point beyond which they are no longer viable for use. Instead of stacking these used batteries in some fenced landfill for our grandchildren to deal with, Daimler AG is adapting electric car batteries into energy storage units. The most recent installation is an Elverlingsen, South Westphalia, “live replacement parts store” for the fleet of third generation Mercedes electric smarts.

energy storage

A joint venture between partners Daimler AG, its subsidiary Mercedes-Benz Energy, GETEC ENERGIE, and technology company The Mobility House has bundled a total of 1920 battery modules in a plant in Elverlingsen in South Westphalia to create an energy storage facility. The stored battery modules are sufficient for at least 600 vehicles. With installed power output of 8.96MW and energy capacity of 9.8MWh, the battery storage plant is available to the energy market, for example, for supplying primary balancing power. Its modular design enables the system to continuously and fully automatically stabilize the power grid...

Three Stationary Mass Energy Storage Facilities Are Already Being Deployed...

Europe’s largest spare parts storage facility is in Hannover. More than 3000 modules there provide a total capacity of 17.5 MWh hours. This is enough to meet the daily power consumption of around 3, 200 households. With an output of 13 MWs, fluctuations in the power grid can be balanced in a matter of seconds.

Lunen is home to the world’s largest second life energy storage facility. It comprises 1000 modules with a capacity of 13 MWh hours. It can store enough electricity to meet the daily requirements of around 2300 households.

Elverlingsen is the location of the third energy storage facility incorporating 1920 modules in total. With a storage capacity of 9.8 MWh, it can supply around 1800 homes with electricity each day. In collaboration with partners, Daimler is developing mass energy storage systems for a “huge range of applications such as black start, backup and uninterruptible power supply, peak load management, and off-grid applications. Daimler energy storage units — maximum supply for the energy storage of the future.”...
