Japanese car manufacturer, Nissan has commissioned a 3 MW storage system using a mixture of both second-life and new electric vehicle batteries at the Johan Cruijff ArenA, which is the Netherlands’ largest stadium, and also the home of football club, AFC Ajax.
The 2.8 MWh storage system combines power conversion units provided by U.S.-based power management company, Eaton and the equivalent of 148 Nissan LEAF batteries. It complements the 3 MW rooftop PV system, which was installed on the cover of the stadium in 2014.
Two thirds of the project was funded via a loan from the Amsterdam Climate and Energy Fund (AKEF), while the remaining third came from private funds. A return on investment is expected within 10 years, although this is said to be a conservative estimate.
“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,” Nissan said in its statement.
While attending the inaugural event, pv magazine learned that the project, which is the result of a cooperation between Nissan, Eaton, The Mobility House and BAM, is also currently in the process of installing 18 EV chargers in the stadium’s carpark. Another 200 will be added over the next two years.
“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 press release continuned.
The project was one of the winners of the pv magazine award for Top Business Model. Read more about the project next week, with interviews from Nissan and Eaton.
