Extreme weather events affect power systems in many ways. Among them, overhead lines with wide span and fragile structure are highly vulnerable to damage and
READ MOREAlthough using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
READ MOREEnergy storage may be a key tool to integrate renewable resources into the electricity grid. Some electricity resources, such as nuclear or coal-burning facilities, produce energy on-demand. Renewable resources, such as wind and solar power, are not always available to match demand, since the wind doesn''t always blow and the sun doesn''t always
