207. To ask the Minister for Communications, Climate Action and Environment if his Department has estimated the significant levels of electricity required by data centres by the end of 2019; his plans to power the expected further increase in power required by these facilities by 2025; and if he will make a statement on the matter.

Government policy in relation to the Role of Data Centres in Ireland's Enterprise Strategy is primarily a matter for my colleague, the Minister for Business, Enterprise and Innovation in the first instance. The Government Statement on the role of data centres in Ireland's Enterprise Strategy, 2018 recognises that a plan-led approach is needed to develop a range of measures to promote regional options for data centre investment, minimising the need for additional grid infrastructure.

While data centres have until recent time accounted for less than 2% of Ireland’s total electricity demand, EirGrid, in their Generation Capacity Statement 2019-2028, project that demand from data centres could account for 29% of all demand by 2028. EirGrid, in its capacity as the transmission system operator, continually model and forecast the predicted future growth of electricity demand in their published analysis such as Tomorrow's Energy Scenarios, which is available on their website at www.eirgrid.com

While data centres consume very large amounts of energy they have a flat, predictable demand profile meaning that they use the same amount of electricity day and night and therefore require a range of generation technologies to meet their demand. Significant increases in volumes of generation capacity, including from renewable energy sources, will be required to meet Ireland’s electrification objectives and demand from heat pumps, electric vehicles and data centres. The Climate Action Plan sets out a number of actions to ensure that data centres are accommodated in a sustainable manner.

Corporate power purchasing of renewable energy by large energy users will also be critical to supplying data centre demand as will ensuring that large demand connections are regionally balanced to minimise grid reinforcements and the costs to consumers.
