Wayside Energy Storage

Envitech designs and manufactures wayside energy storage systems to improve the energy efficiency of DC traction power grids: 

The BASS reduces voltage drops that can occur in some areas of the distribution grid, which improves the performance of the trains. The BASS operates off of the public energy grid and can store energy during off-peak periods and send it back during peak operation. In an event of a power failure, the BASS can also feed the traction grid.

The Envistore captures excess regenerative energy on the traction power line, stores it, and returns it to the traction line when needed, reducing peak demand (peak shaving). The ENVISTORE helps reduce voltage drops on transit power systems, therefore improving transit performance.
