Segmentation of energy storage applications

Energy storage can be useful in many ways for the stakeholders of the electricty value chain. Due to its high capital intensity, it is crucial that more than one revenue stream can be served.

In the table below, the main storage applications considered by EASE are listed.

We are currently developing consensual definitions for each application. These will be available soon.

Renewable Generation

  • Distributed generation flexibility
  • Capacity firming
  • Limitation of upstream disturbances
  • Curtailment minimisation
  • Ancillary services renewable energy sources support

Conventional Generation

  • Support to conventional generation
  • Black start
  • Arbitrage
  • Electric supply capacity


  • Primary, secondary & tertiary frequency control
  • New ancillary services
  • Participation to angular stability
  • Investment deferral
  • Improvement of the frequency stability of weak grids
  • Transmission support


  • Capacity support
  • Reactive power compensation
  • Distribution power quality
  • Limitation of upstream disturbances
  • Intentional islanding
  • Contingency grid support
  • Dynamic local voltage control
  • Investment deferral

Customer Services

  • Provide continuity of energy supply
  • End-user peak shaving
  • Manage time-of-use energy cost
  • Provide particular requirements in power quality
  • Compensation of the reactive power
  • Limit upstream disturbances
  • Electric vehicles integration
  • Demand charge management
  • Continuity of energy supply

Energy Storage Technologies

EASE supports all energy storage technologies and believes that they should be addressed agnostically.
