The overall objective of the Programme for Government climate and energy commitments is to underpin Ireland’s long-term, sustainable competitiveness as we transition from a fossil-fuel based economic model to a carbon-neutral one. Decarbonisation of our electricity system and upgrading our grid infrastructure will be critical to achieving this ambition. It will mean making far-reaching changes to our electricity system that will affect everyone. EirGrid have this week launched a detailed consultation entitled Shaping Ireland’s Electricity Futurewhich outlines innovative approaches to developing the grid in order to meet our ambitious 2030 renewable energy targets. Details on the public consultation and how to have your say are available at: consult.eirgrid.ie

Domestic sources of renewable energy will also necessitate significant grid infrastructure upgrades over the coming decade as microgeneration becomes more commonplace.

The recent Price Review decision from the Commission for Regulation of Utilities (CRU) on the allowable spend on our electricity grid over the next five years signalled a dramatic increase in funds for grid enhancement. For example, ESB Networks' allowable capital expenditure has been increased by 84% over the previous period.

The major ramp up in the levels of renewables on our power grid to achieve the Government's 70% renewable electricity target by 2030 and the move to a highly electrified economy will give rise to challenges in ensuring security of supply and maintaining a reliable system for all customers during the transition. The winter capacity margin of available electricity supply over demand has reduced every year over the past five years mainly due to increasing demand, including from data centres, and peat generation exiting the market. The CRU and EirGrid, which both have statutory responsibilities to ensure security of electricity supply, are actively monitoring matters.

My Department is carrying out a review of the security of energy supply of Ireland’s electricity and natural gas systems. The review will include a detailed technical analysis and a public consultation. It is planned that the review will be completed by the end of 2021.
