The non-residential sector makes up most of the Ireland’s power demand, accounting for 72% of total metered electricity in 2025. The total national metered consumption reached 32,986 GWh in 2025. Out of this, the non-residential sector was responsible for 23,911 GWh.
The non-residential sector has increased from 22,953 GWh in 2024 to 23,911 GWh in 2025, rising by 4%. Unlike typical residential electricity consumption – which usually peaks heavily in the colder, darker winter months (Q1 and Q4) and drops in the summer (Q2 and Q3), the non-residential sector has a more even distribution, with only slight variations in the share of energy use between different quarters.

The highest non-residential consumption was observed within Dublin Postal Districts with 15% of total national electricity consumption, followed by Cork with an 8% share in 2025. The highest consumption within Dublin Postal Districts was observed in Dublin 15 (444 GWh) and Dublin 2 (435 GWh) in 2025. The highest growth was observed in Dublin 17 with a 12% increase when compared with 2024.
The number of non-residential meters grew by 28,786 since 2016 reaching 305,597 in 2025. The highest number can be observed in the Dublin area at 83,586, increasing by 1% when compared to 2024.
The peak metered electricity consumption demand period for large energy users (DG10 and TCON) occurred between 14:00 and 16:00. The demand pattern is broadly even over the 24-hour daily period. This contrasts with the peak daily demand of Metered Electricity Generation which occurs around 17:00 to 19:00. The unaggregated values for years 2023-2025 can be found in PxStat Table MEC04. The values in the PxStat Table MEC04 are in Coordinated Universal Time (UTC), where in aggregated plot on Figure 3.2 are presented in Daylight Saving Time (DST) to better illustrate socioeconomic usage pattern.
