Is There Enough Power?

When demand for electricity is greater than what is currently possible to produce or import a last resort is to disconnect consumers from the electricity system in order to maintain the balance of the system.

They describe the responsible actors, how critical electricity users are identified and prioritised, and provide guidance on how to improve the planning process.
