Electricity accounted for 30% of business energy costs in 2018

Purchases of electricity accounted for 30% of the total energy purchase costs by enterprises in 2018 (see Headline Table and Figure 1). Purchases of aviation transport fuels accounted for a further 25% followed by natural gas (21%) and road transport fuels (13%). Total energy costs rose from €7.9 billion in 2009 (the first year of this series) to €9.3 billion in 2013. They decreased to €7.8 billion in 2016 and then increased to €9.7 billion in 2018 (see Table 2C).

This release is based on the National Accounts residence principle. This means that energy used abroad by enterprises resident in Ireland is included e.g. flights between other countries by an Irish resident airline. Energy used in Ireland by foreign resident enterprises is not included. See Background Notes for more information.

The mix of energy products used by Irish enterprises in 2018 is given in Figure 1. In terms of kilotonnes of oil equivalent (ktoe), natural gas accounted for 33% of the total ktoe with aviation fuels accounting for a further 31%. Electricity comprised another 13% and solid fuels an additional 8% (see Table 2A).

In monetary terms, the proportion of total fuel purchase costs accounted for by each energy product in 2018 was quite different than the ktoe distribution (see Tables 2A and 2C). This difference is partly accounted for by electricity being used for final energy consumption whereas a substantial proportion of natural gas is used for intermediate consumption to make electricity (see Table 4A).

The Industry sector accounted for 48% of total non-domestic energy consumption in 2018 in terms of ktoe. The energy products used by industry have a lower relative cost than those used by the Services sector. Hence the proportion of purchase costs accounted for by the Industry sector was 37% in 2018 compared with 63% of fuel purchase costs being paid for by the Services sector. The total consumption by industry and services increased by 0.6% in quantity terms (ktoe) in 2018 and rose by 17% in cost terms (see Tables 1A and 1B).

The use of energy from renewables and from waste increased from 215 ktoe in 2009 to 397 ktoe in 2018 or by 85% over the nine years (see Table 2A).
