Energy Optimisation for Public Transportation

Railway, tram and subway systems have a very large quantity of unused energy available, which is “burned off” via rheostatic and mechanical brakes on the vehicles and thus remains unused. Stationary, modular flywheel storage of the net powersafe company stores the electrical energy generated during braking and makes it available later for accelerations. The high level of efficiency, the non-contact magnetic bearings with a floating rotor and minimum maintenance guarantee the transport operator maximum cost savings.

The Vycon® modular flywheel storage is the core component of the system. The operating software and visualisation are special developments of net powersafe and are brought to bear as standard features in applications for energy optimisation. This can truthfully be referred to as a “pioneering” engineering achievement.

In the past few years, net powersafe has installed or purchased more than 20 MVA of flywheel installations in Switzerland. This excellent record makes our company the market leader in this technology field. Reliable, efficient and ecologically significant energy supply is the focus of our activities.
