The National Energy Balance presents detailed information on how and where energy is used in Ireland for a given year.

The Balance shows the flow of energy from production and transformation to total final consumption. This is shown in the form of a table. The National Energy Balance is our primary statistical release. It is the basis of much of the further analysis we do.

2018 Energy Balance

The National Energy Balance is published each year in October. In April we publish a summary provisional balance with the headline figures for energy supply. These are subject to revision.

Main points from the 2018 Final Energy Balance:

Energy use increased in 2018 by 1.6%. Energy related CO2 emissions reduced by 1.2%. This was largely due to a one-off outage at Moneypoint power station. There was a significant reduction in coal used for electricity generation as a result.

  • Primary energy use increased by 1.6% in 2018 to 14.7 Mtoe, while the economy grew by 8.2% as measured by gross domestic product (GDP) and 3.3% as measured by modified domestic demand (MDD).
  • CO2 emissions from energy use fell by 1.2% in 2018 compared with 2017. This was due to reductions in coal and peat use, mainly in electricity generation, along with increased contribution from renewable energy sources.
  • Coal use fell by 34% in 2018. This is mostly due to the Moneypoint coal powered electricity generating station being offline for approximately 3 months towards the end of the year. Coal accounted for 4.9% of all energy use in 2018, down from 7.6% in 2017.
  • Renewable energy sources grew by 10.2% in 2018, and accounted for 10% of all energy used.
  • Oil use increased by 3.3% in 2018 and accounted for 49% of all energy use.
  • Natural gas use grew by 3.8% in 2018, and accounted for 31% of all energy used.
  • Peat use fell by 1.3% in 2018 and accounted for 4.7% of all energy use.
  • Import dependency increased slightly in 2018 to 67% from 66% in 2017. Gas imports increased by 23% (320 ktoe) and more than offset reduced coal imports, which fell by 31% (385 ktoe).  Indigenous gas production was down by 3.6% also.
  • 61% of natural gas use in Ireland in 2018 came from indigenous sources, down from 66% in 2017.

Electricity Generation

  • Demand for electricity increased by 4.4% in 2018 while energy used to generate electricity fell by 4%.
  • Coal and peat use in electricity generation were down by 44% (379 ktoe) and 3.3% (17 ktoe) respectively in 2018.
  • Natural gas input to electricity generation increased by 1.5% (37 ktoe), while the contribution from wind increased by 16.1% (103 ktoe), biomass by 25% (34 ktoe) and wastes by 61% (34 ktoe).
  • These changes have resulted in the CO2 intensity of electricity falling to a new low of 375 gCO2/kWh in 2018, down by 14% from 436 gCO2/kWh in 2017.

Renewable Targets

  • Overall renewable contribution to gross final energy consumption in 2018 was 11.0%, up from 10.5% in 2017.
  • Renewable electricity share of gross final consumption of electricity (RES-E) increased to 33.2% (30.1% in 2017).  Wind contributed 28.1 percentage points of this.
  • Renewable heat share of gross final consumption of heat (RES-H) reduced to 6.5% in 2018, down from 6.7% in 2017.
  • Renewable transport share of transport (RES-T) also reduced to 7.2% in 2018, down from 7.4% in 2017.
