curtailment

/kərˈteɪlmənt/

Definition

The deliberate reduction or restriction of power generation, specifically when energy production exceeds grid capacity or demand.

Etymology

Derived from the Middle English 'curtail' (to cut short) and the Old French 'curtailler', which combined 'curt' (short) and 'tailler' (to cut). It entered modern English as a noun describing the act of reducing or diminishing something.
