Energy Storage — Grid Integration Toolkit

Energy storage refers to technologies capable of storing electricity generated at one time for later use. These technologies can store energy in a variety of forms including as electrical, mechanical, electrochemical or thermal energy. Storage is an important resource that can provide system flexibility and better align the supply of variable renewable energy with demand by shifting the

Thermal Energy Storage

Capacity defines the energy stored in the system and depends on the storage process, the medium and the size of the system;. Power defines how fast the energy stored in the system can be discharged (and charged);. Efficiency is the ratio of the energy provided to the user to the energy needed to charge the storage system. It accounts for the energy loss during the
