The Add-On Energy Management System

New World Generation is pursuing the development of an energy storage system
to capture wasted or unused energy. This add-on energy management system can be integrated with power plants of all types (coal-fired, gas, oil, nuclear).

When developing its independent energy storage system that would be incorporated with wind turbines, NWG began exploring whether the system could be integrated with a coal-fired, steam turbine power plant. They discovered that the system could be used to cycle through peak/off peak capacity to meet demand as required.

Some additional benefits of this add-on energy management system include:

Improved availability of the power plant by reducing down time
Increased efficiency by operating the boiler and the high pressure components at a constant loadImproving overall operating efficiency by eliminating the steam turbine bypass system

Gryphon International, a leading thermal power and energy industry-engineering firm, conducted a preliminary analysis utilizing this system with an existing coal fired power plant. Gryphon concluded that the plant would be given the flexibility of 50% of its total rated power to meet the swings between peak/off-peak demand. The overall electrical efficiency of the Add-On Energy Management System was calculated to be close to 50%.
