How Gas Prices Are Set
Natural gas is traded on European spot markets, primarily the Dutch TTF (Title Transfer Facility) hub. The TTF price is the global benchmark that Irish suppliers and generators use to buy and hedge their gas supply. When TTF rises, Irish energy costs rise — often with a 3-6 month lag as contracts and hedges work through the system.
The 2021-2023 Energy Crisis
The most dramatic gas price event in recent memory began in late 2021 and peaked in August 2022, when TTF hit nearly €350/MWh — more than ten times historical norms. The causes were multiple: post-COVID demand recovery, reduced Russian pipeline flows to Europe, low gas storage levels, and extended periods of low wind power across the continent.
Irish electricity prices tracked this closely, with some household tariffs briefly exceeding 60 cent per kWh — a level that was unthinkable just two years earlier.
Where Prices Stand in 2026
TTF prices have fallen significantly from their 2022 peak, settling into a range of €30-€50/MWh through 2025-2026. This is still above pre-crisis norms (€15-€25/MWh), reflecting structural changes including continued LNG reliance and the slow replacement of Russian supply with alternative sources.
Irish retail electricity prices have not fallen as far as wholesale prices, partly due to supplier hedging, network cost increases, and carbon taxes continuing to rise.
Ireland's Gas Dependency
Approximately 50% of Ireland's electricity is generated from natural gas. Unlike most large European countries, Ireland has no nuclear plants, limited hydro capacity, and is not connected to the UK or continental grid via high-capacity interconnectors (though new ones are planned). This makes Ireland unusually vulnerable to gas price swings.
LNG and Energy Security
Ireland has no domestic LNG terminal, meaning all gas arrives via pipeline from Scotland (Moffat interconnector). There are proposals for a floating LNG terminal, but these remain politically contentious given climate commitments. Until Ireland's renewable buildout significantly reduces gas dependency, wholesale price volatility will remain a feature of Irish energy bills.
Renewable Energy as the Long-Term Answer
Ireland has some of the best wind resources in Europe. The government's target of 80% renewable electricity by 2030 would dramatically reduce exposure to gas price swings. Every wind turbine and solar panel built reduces the amount of gas Ireland needs to buy on global markets.
Solar panels on your roof are a practical way to take personal control — generating your own power means you buy less from the grid, regardless of where wholesale prices go.
