We want to be a driving force to ensure more climate-friendly solutions for Norwegian sports facilities. The energy storage system at the Bislett Stadium enables us to better utilise the production of solar power, while the control system reduces energy expenditures.

The world's fifth most important sports arena of the 20th century

The current Bislett Stadium opened in 2005 and is built in the same place and the same distinct architectural style as the old stadium, which was demolished in 2004. In addition to athletics, the stadium is used for football, concerts and other events. The stadium is one of Norway's best-known sports arenas and hosts international ExxonMobil Bislett Games athletics event each year. More than 50 athletics world records and 18 speed skating world records have been set at the Bislett Stadium, which Sports Illustrated named the world's fifth most important sports arena of the 20th century.

Ensuring back-up power and peak shaving while using more self-generated solar energy

The stadium wanted to invest in an energy storage solution that would enable it to shave peaks in energy consumption and usage, utilise its production of solar power more intelligently and ensure back-up power for the stadium and the events it hosts. In a worst-case scenario, a power outage during an event, concert or maintenance intervention would not only prove disastrous for the Bislett Stadium, but also for the surrounding areas and people who rely on the same power grid.

Eaton xStorage Buildings system featuring a 100 kW power conversion system and three racks with 30 Eaton battery packs

The sports stadium now benefits from the installation of an Eaton xStorage Buildings system, which includes a 100 kW power conversion system and three racks with 30 Eaton battery packs consisting of second-life Nissan LEAF battery modules. This is a great example of the circular economy. In the summer of 2018, 1,100 m2 of solar panels were installed at the Bislett Stadium, which can produce up to 150,000 kWh each year. The energy storage system that is currently installed can store up to 109 kWh, but it can easily be upscaled to match growing needs in the future.

Demonstrating environmental responsibility

The xStorage Buildings system reduces energy consumption from the grid during peaks by using the back-up solar energy stored in Eaton’s xStorage Buildings battery packs. Managing stored energy and distributing it responsibly supports the grid by making it more resilient and stable. The installation at the Bislett Stadium demonstrates environmental responsibility, and it is expected that more such energy storage systems will be installed in Norway in the future.
