EnergyAware: Bahnhof and Eaton are collaborating in Sweden

The Eaton Through this, the Bahnhof can help balance the grid energy supply and therefore provide it with a cash refund from Svenska Kraftnät (which operates Sweden’s electricity system).

In June 2020, Bahnhof upgraded its existing Eaton uninterruptible power supply (UPS) with Eaton EnergyAware technology at its Thule server plant in Stockholm. The main purpose of the Eaton UPS system is to protect the data center from various disturbances coming from the grid, thus contributing to the provision of an uninterrupted power supply and at the same time the efficient use of renewable energy.

The Eaton Power Xpert 9395P UPS at the Bahnhof facility provides Svenska Kraftnät with a fast frequency reserve (FFR) thanks to the EnergyAware service. With this solution, Bahnhof not only provides protection against mains disturbances, but can also offer unused energy stored in UPS batteries to Svenska Kraftnät, which uses this energy to balance the electricity grid. Svenska Kraftnät provides a cash refund to the Bahnhof in exchange for electricity. New measurement and communication devices have also been installed in the data center, allowing the network frequency to be measured at regular intervals. Accordingly, Thule became the first data center in Sweden to use FFR.

“UPS ensures that servers and other critical equipment are always given priority, and Bahnhof can choose the amount of energy it wants to make available to the network. This could spread a whole new way of thinking: investing in infrastructure can be achieved by purchasing a UPS system. You can invest in the maximum capacity to be used in the future from the beginning of the investment, because you can sell the unused capacity to the network, which makes it easier to expand, as there is no need for complicated additional investments and upgrades later. ”

Says Mathias Jensén, Eaton’s customer manager.

The EnergyAware project launched in 2019

EnergyAware aims for companies to help stabilize the frequency. These companies receive a refund from the electricity provider. The amount of the refund depends on how much energy and for how long the company contributes to network stability.

“It is important for Bahnhof to be able to contribute to the electricity grid through the equipment we need to ensure our own operation anyway. If we can improve the quality of the grid electricity supply and even generate revenue from it, that is of course to be welcomed. ”

Says Mikael Wallén, head of Bahnhof data center infrastructure.
