Flexibility

Also called: flex, demand flexibility Energy flexibility is the ability to change electricity demand or supply in response to site, grid, market or price conditions. EV charging is flexible when charging can move in time or change power without preventing the vehicle from meeting its required departure state. Flexibility can be used locally for load balancing or commercially through demand-response and aggregation services. Batteries and bidirectional vehicles can add further flexibility by changing both import and export. The old Versinetic glossary also used "Flex" for a former vehicle-finance or leasing label. That brand-specific meaning should be treated as historical rather than mixed into this energy-system definition.
