In commentary on his report on Ireland and large British limitation of renewable energy, the Fintan Devenney of Montel Energy described the solar restriction of Great Britain as ‘negligible’ during the first six months of 2025. Solar Curtailment in Ireland has been seven -time since 2022.
During the first six months of 2025, 88,725 GWH van Zonne energy was shortened in the Irish Single Energy Market (ISEM), according to a report from Montel Energy, which looks at renewable energy limitation in both Ireland and Great Britain.
Solar Curtail in Ireland has increased seven times since 2022. The report from Montel noted that sufficient wind and solar generation has been restricted on the island of Ireland to meet all domestic electricity consumption in County Dublin from January to June 2025.
Fintan Devenney, senior energy analyst, Montel Energy, said PV -Magazine That the system in ISEM “struggles to cope with the rapid increase in the capacity of solar generation.”
“Downward shipment (the period of Ireland for power that is produced but cannot be used) volumes of solar energy are dramatically higher than a few years ago,” he added. “Often the reasons are due to local limitations or system level problems around too much renewable output for the schedule to handle.”
ISEM includes Noord -Iierland and the Republic of Ireland and is jointly managed by the system operators of both areas of law -Eirgrid in the Republic and Soni in North Ireland. In March PV -Magazine Reported that in 2024 Noord -Iierland doubled his solar bearing and that year 16.9% of his solar energy reduced, an increase of 7.9% in 2023.
In the meantime, Devenney described the sun brimette of Great Britain as ‘reasonably negligible’. Less than 0.1% of the total limited volume in Britain during H1, 2025 came from solar energy, he said. The report stated that less than 1 GWH Zonne -Zon has been rejected in the past three years.
However, it also referred to data from the System Operator of Great Britain Neso, who suggests that the self-brand volumes on solar energy could rise between 10 and 20 TWH in 2040.
“It is probably the case that solar assets will start each other’s income and result in self-listing in the future, as reported by Neso,” said Devenney. He emphasized the fact that Neso refers to self-change, which means that the solar energy would be limited for economic reasons instead of lack of generation’s availability.
The Analyst Van Montel told PV -Magazine That the future self-collection would probably be due to increased amounts of negative prices and subsidy contracts. The NESO figures are modeled in a non-restricted system, so the reason is not to do with limitations of restrictions.
Great -Britain restricted a total of 4.6 TWH of electricity in the first six months of this year, while the total of ISEM was 905 GWH. In both markets, wind was the most important source of limited renewable energy.
In Groot -Britain, North Schatland accounted for 86% of the total limitation volume, with more than 4 TWH of Wind in the first six months of 2025. During this period, more than GBP 116 million was paid to wind farms in the region, accounting for 76% of the total criminal costs in Great -Britain.
Noord -Schandland is one of the largest generation areas of the Great British Market; The low population density and the cool, windy climate make it an ideal location for large batteries and wind farms. The electricity generated by these batteries and wind farms is sent via the grid to densely populated, large demand areas such as London. However, limited grid capacity to transfer much of this power means that much of it is limited, especially in the transmission limit areas.
