ENVILINE™ ESS – Energy Storage System

Reduce energy and peak power costs

ENVILINE ESS is a wayside energy management system that stores and recycles the surplus braking energy, feeding it back to the power line to assist the acceleration of the train, helping reduce the energy consumption up to 30 percent.

Whenever a train brakes, its kinetic energy is converted into electricity and returned on the traction power line. Most of the time, onboard loads and distant trains can only take a portion of this energy, and the surplus is wasted into onboard or wayside resistors. The ENVILINE ESS stores and recycles this surplus energy, helping reduce the energy consumption of a rail transportation system up to 30 percent.

The ESS can come with either super capacitors (for short term storage and recovery of the braking energy) or with batteries for additional benefits and revenue generating services.

Additional benefits
The ESS can be configured with super capacitors and batteries to combine the benefits of braking energy recovery and peak power reduction with local grid support services such as frequency regulation, peak shaving or demand shifting. The ESS can become a smart grid asset, providing emergency power or demand response services to the local energy distribution company.
