Benefits of Reliable Hybrid Power Supply
  • Balances variability with variable power sources
  • Smoothes/levels supply to grid
  • Represents "spinning" capacity
  • Optimizes cost
  • Leverages existing technology
  • Adaptable to technology improvement
This is a unique way of solving variability with variability by matching the design of the energy storage system with individual customer needs, combining multiple storage technologies into one integrated system that automatically dispatches the right technologies at the right time. The patent-pending approach applies our rich heritage and technological leadership to support distributed energy commercialization with hybrid storage solutions.  EaglePicher high energy efficiency systems can be used to minimize the cost of energy storage.

PowerPyramid™ Technology

The EaglePicher PowerPyramid™ approach surpasses typical storage techniques by leveraging multiple storage technologies, minimizing the shortcomings typically associated with any single electrochemical systems, and providing optimized performance. Electrochemical batteries are capable of providing virtually instantaneous power that will meet the requirements of the various scales of power deviation that occurs with intermittent renewable energy sources or applications. This breakthrough concept will set new standards for integrating intermittent renewable energy sources.
