Details in relation to All-Island electricity system demand and fuel mix are publicly available on the EirGrid website at http://www.eirgridgroup.com/. EirGrid’s “All-Island Generation Capacity Statement” (pages 14 and 15) provides details of the 2016 generation fuel mix for both Ireland and Northern Ireland. The document is available at http://www.eirgridgroup.com/site-files/library/EirGrid/4289_EirGrid_GenCapStatement_v9_web.pdf
In Ireland in 2016, final consumption of electricity reached 29,413 GWh while the corresponding figure for Northern Ireland was 8,892 GWh. The following table provides a breakdown of 2016 generation in Ireland by technologies on a percentage basis.

In regard to future electricity demand, EirGrid have modelled a number of scenarios in their 2017 publication “Tomorrow’s Energy Scenarios". Each scenario predicts a different possible future for the generation and consumption of electricity out to 2040. A link to the document is available at
