The bigger energy picture.
Wind is part of a wider system. Explore where energy comes from, where electricity is used, and why available wind is sometimes turned down.
These are published historical series, each with its own reporting period. They are separate from the current grid readings. Null values are shown as unavailable.
What powers Ireland?
All energy use, including transport and heating—not just electricity.

API coverage is shown above. Spreadsheet releases can lead the API and are not silently mixed into this series. Fuel values are primary energy requirement; sector values are final energy consumption. The two measures have different totals.

County totals and Dublin postal districts overlap and must not be added together. Non-residential consumption includes many activities, not only data centres.

Wind that could not be used.
Dispatch-down combines network constraints and system-wide curtailment. This is the percentage of available wind energy turned down in Ireland, not the share of demand supplied by wind.
