Electrical Power worX is currently in the process of developing an Ultracapacitor-Based Energy Storage System for use in an electrified Mass Transit System. This energy storage system is capable of reducing overall energy consumption by up to 25% while stabilizing the energy delivery to the vehicles operating from the electrified supply.

At right are some typical applications where an ultracapacitor energy management system can provide significant energy conservation and stability. The size of the ultracapacitor storage unit can be adjusted to match the requirements of the system, incorporating appropriate monitoring and control devices.
A power converter is used to control the flow of power in and out of the ultracapacitor bank, to receive and deliver energy as required by the application.
Specialized control electronics and software algorithms allow the EPX system to store and supply energy to the grid, as well as monitoring the state of the distribution network to balance the EPX system response between the goals of energy conservation and network stabilization.

| One application of this system will be ready for on-site demonstration in 2009. |
