Definition: grid-connected installation with defined electrical boundaries, which can include civil engineering works, energy conversion equipment and related ancillary equipment, comprising at least one electrical energy storage, which extracts electrical energy from an electric power system, stores this energy internally in some manner and injects electrical energy into an electric power system

Note 1 to entry: The EES system is controlled and coordinated to provide services to the electric power system operators and to the electric power system users.

Note 2 to entry: In some cases, an EES system can require an additional energy source (non-electrical) during its discharge, providing more energy to the electric power system than the energy it stored (compressed air energy storage is a typical example where additional thermal energy is required).

Note 3 to entry: This note applies to the French language only.
