Great Island — 216 MW Oil

Great Island ranks as the 12th largest power generation facility in Ireland, with a capacity of 216 MW, making it a significant player in the country’s energy production landscape. As the second-largest oil plant in Ireland, it represents an essential part of the energy mix in a nation where gas dominates the generation profile, constituting a significant portion of the 8,545 MW total capacity across 59 plants. This facility’s contribution of 2.53% to Ireland’s overall capacity highlights its importance in ensuring energy reliability, particularly during periods of high demand. Operated by Endesa, Great Island employs oil-fired generation technology, which, while not as environmentally friendly as renewables, plays a crucial role in providing reliable energy when other sources may be insufficient. Situated near the Castledockrell wind farm, which has a capacity of 41.4 MW, Great Island benefits from the complementary generation of renewable energy, reinforcing the grid’s stability. The proximity to wind energy sources illustrates the growing trend in Ireland towards a more diverse energy portfolio, combining traditional and renewable resources to meet national goals. Despite being one of the few oil-based plants in the country, Great Island’s role is critical, particularly as Ireland transitions toward more sustainable energy solutions. Looking to the future, this facility will likely play a transitional role, balancing supply gaps as the nation invests further in wind and solar technologies. Great Island exemplifies the ongoing evolution of energy strategies in Ireland, reflecting the challenges and opportunities of integrating oil power into a cleaner energy future.
