Curtailment
Also known as: Renewable Curtailment
Switching off or reducing renewable generation because the grid cannot absorb the power being produced at that moment.
In energy storage
BESS co-located with solar or wind can absorb generation that would otherwise be curtailed due to grid constraints, shifting delivery to hours when the grid can accept it. Standalone BESS may also be curtailed by the TSO or DSO when the network is congested — curtailment events are typically excluded from availability guarantee calculations.
