Curtailment and firm capacity
Curtailment is a required reduction in a customer’s electricity use, or a generator’s output, ordered by the utility or grid operator during constraints or emergencies. Firm capacity is service the provider commits to deliver without interruption except in rare emergencies. Some large-load arrangements offer faster or cheaper service in exchange for agreed curtailment, which affects how much on-site backup a data center needs.
