Curtailment: When Clean Power Has Nowhere to Go

Tue, 12 May 2026 00:00:00 +0000

Curtailment is one of the strangest ideas in the modern power system. A solar farm can be ready to produce. A wind plant can have strong wind. The electricity can be clean, useful, and technically available. Then the grid operator tells the project to turn down anyway.

That sounds wasteful because it is, at least in the ordinary sense. But it is not usually a sign that the equipment failed. Curtailment happens when the grid cannot safely absorb or deliver all the power that is available at a particular place and time. The power exists, but the system around it is not ready for that exact combination of supply, demand, wires, voltage, reserves, and operating limits.
