Power Generation

Natural gas plays a vital role in the Irish energy system

The gas network generates a large proportion of the electricity we use to run our homes and businesses. It provides flexible and cost-effective energy security when intermittent renewable energy generation is low.

Did you know?

  • 30% of Ireland's primary energy use is provided by the gas network

  • 50% of Ireland's electricity supply is generated by the gas network

  • 29% of gas in the network is supplied by indigenous sources

Interview with Denis O'Sullivan

Our Chief Operating Officer, Denis O'Sullivan,  talks about how important gas is both today and in Ireland's cleaner energy future. 

Cleaner compared to other fuels

Natural gas is cleaner compared to other conventional fuel types when generating electricity. In comparison, coal and peat powered generators release heavy levels of greenhouse gas emissions. Natural gas produces 67% less emissions than peat, and 61% less than coal. View how much cleaner gas is on this chart.*

Ideal partner for renewable energy sources

It is vital for Ireland to use renewable sources for power generation. However, intermittent renewable sources, such as wind and solar, can create gaps in energy supply levels. Gas-fired power plants provide the flexible and reliable back up needed to meet electricity demand.

Security of supply

The gas network allows Ireland to generate its own electricity. Indigenous gas is supplied from the Corrib gas field in Co. Mayo, with two subsea interconnectors with the UK providing significant energy security. Indigenously produced renewable gases, such as biomethane and hydrogen will add further diversity and security of supply.

Moving Ireland towards a cleaner energy future

By switching from peat and coal to gas-powered plants, Ireland can realise immediate emissions savings. And, as the volume of renewable gas in the network gradually increases, gas-powered generation will become increasingly more sustainable. This is how we are working to move Ireland towards a cleaner energy future.

Data Transparency Portal

In May 2018, we launched a new Data Transparency portal. You can view the 'Commercial Exit Point Allocations' graph to see natural gas usage for power generation in Ireland.
