Gas Overtakes Wind as Northern Ireland’s Top Power Source in Early 2025
Published · 2 min read

In March and April 2025, gas became Northern Ireland’s main source of electricity, just ahead of wind power. This change shows how the region is balancing different energy sources while moving towards cleaner energy.
Electricity Generation Breakdown
System Operator for Northern Ireland (SONI) manages the electricity grid. Their data shows that gas provided the most electricity during these two months.
- Natural Gas: Main source of electricity in March and April 2025
- Wind Energy: Close second, but slightly less than gas
- Other Sources: Solar, biomass, and electricity imports
Wind farms still produced a lot of power, but changing weather affected their output. Gas plants provided steady power when wind was low.
SONI’s Role in Energy Transition
SONI ensures that electricity is supplied reliably while adding more renewable sources. They aim to build a system that meets growing energy needs and environmental goals. Their plans include upgrading infrastructure and investing in new technologies. You can learn more on their website: www.soni.ltd.uk.
“At SONI, we’re committed to managing the transition to a cleaner, more sustainable energy future,” said a spokesperson. They highlighted the need for smart technologies to handle variable sources like wind.
Reasons for Gas Leading
Several factors contributed to gas leading over wind:
- Consistency: Gas plants provide steady power, unaffected by weather
- High Demand: Colder months increase energy use
- Backup for Wind: Gas steps in when wind generation drops
This doesn’t mean a move away from renewables. Northern Ireland continues to invest in wind, solar, and storage. Gas serves as a bridge during this transition.
Future Plans for a Balanced Grid
Northern Ireland aims for a balanced energy mix. SONI is working on:
- Improving connections with neighboring countries
- Increasing battery storage
- Better forecasting for renewable output
- Upgrading transmission networks
Wind energy has great potential. On some days, it supplies over 70% of demand. But since wind can vary, gas helps fill in the gaps.
Public Response and Next Steps
Environmental groups push for faster adoption of renewables. They call for more investment in offshore wind and community energy projects.
SONI engages with stakeholders, including policymakers and residents. They share data and updates on their website to keep the public informed.
Conclusion
March and April 2025 show a transitional phase in Northern Ireland’s energy journey. Gas leads for now, but wind remains crucial. As technology and infrastructure improve, the energy mix will continue to evolve. Stability, sustainability, and collaboration are key focuses.
