**Solar Power and Energy Transition**
As the world transitions to a low-carbon economy, solar power has emerged as a critical component of this effort. In Ireland, where the government has set a 2030 target of 8 GW of solar PV capacity, the solar sector is playing a vital role in meeting this goal.
Despite the challenges posed by the Irish market, with its high developer risk profiles and lengthy development timelines, solar power has been gaining traction in the country. In fact, according to a report by the Sustainable Energy Authority of Ireland, Ireland surpassed 1 GW of solar generation connected to the grid for the first time last year.
The Irish Market: A Challenge for Solar Developers
However, the Irish market has proven to be a difficult one for developers, with auction prices around €104/MWh – significantly higher than European averages of €60-70/MWh.
- The high developer risk profiles and longest development timelines of any territory pose significant challenges for solar developers in Ireland.
- The auction prices reflect this, with a significant premium being charged for the privilege of developing solar projects in the Irish market.
Solar Farms in Ireland: Progress and Challenges
Despite the challenges, progress is being made in the solar sector in Ireland. Several major solar farms are currently under construction or have been recently completed, including the Clonfad Solar Farm, which is set to be the largest solar farm in Ireland.
| Project Name | Location | Capacity (MW) | Expected Completion |
|---|---|---|---|
| Clonfad Solar Farm | Co. Westmeath | 175 | Expected to be operational |
| Garreenleen Solar Farm | Carlow | 81 | Phase 1 set to become operational in 2026 |
| Lysaghtstown Solar Farm | Cork | 131 | Expected to be operational this year |
Battery Storage in Ireland: A Solution to the Grid Stability Issue
In Ireland, the lack of sunlight throughout the year poses a significant challenge for the grid stability. To address this issue, the use of battery storage systems is becoming increasingly important.
- The Irish market is attractive to battery storage developers, with initial investment of over €300m by companies like Hanwha Energy Corporation.
- However, recent changes to market support mechanisms have created uncertainty around revenue streams, challenging project bankability.
The Importance of Hybrids in Ireland
In Ireland, hybrids are emerging as a promising solution to the battery storage issue. Hybrids enable the storage of surplus solar energy for use during peak demand periods, or to complement daytime solar with nighttime wind generation.
“Hybrids extend the availability of renewable electricity and reduce dependency on fossil-fuel-based backup power,” said the Irish Solar Energy Association.
The Global Context: Solar Power Capacity
Global solar power capacity has reached 2 TW in 2024, after decades of growth. The rapid expansion of solar power is driven by the increasing demand for clean electricity, fueled by the tech industry and electric vehicles.
- The Tech industry is driving the demand for clean electricity, with sectors such as artificial intelligence, data centres, and heat pumps contributing to the growth.
- Electric vehicles are also driving the demand for clean electricity, with the global fleet expected to reach 130 million vehicles by 2030.
Conclusion
In conclusion, solar power is playing a vital role in Ireland’s energy transition, with several major solar farms currently under construction or completed. The use of battery storage systems and hybrids is becoming increasingly important to address the grid stability issue.
