For journalists

Key figures with their sources, and what each one is. Reported figures can be quoted as EirGrid's; modelled figures are Irish Grid estimates and should be described that way. The method page shows how each is made.

Boilerplate

Irish Grid publishes independent evidence on Ireland's electricity grid: how much wind power is turned away, what it is likely to cost electricity customers, and options for using the surplus, including flexible demand. Reported figures come from EirGrid and SONI's annual Constraint and Curtailment reports; modelled figures are published with their assumptions. Irish Grid is an independent, non-partisan research and advocacy site. It has no connection to EirGrid or SONI.
