About this plant

Ranked as the fifth largest power generation facility in Iceland, Sigalda Hydro Plant stands out not only for its capacity of 150 MW but also for its crucial role in Iceland’s renewable energy landscape, where hydroelectric power dominates the energy mix. Commissioned in 1977 and operated by Sigölduvirkjun, this facility contributes 6.04% to the national capacity of 2,485 MW, positioning it as a significant player in the country’s energy sector. The plant utilizes advanced hydroelectric technology to harness the power of flowing water, ensuring efficient energy generation while minimizing environmental impact. Located in the scenic region of Iceland, Sigalda is part of a local cluster of hydro plants, including Hrauneyjafoss, which boasts a larger capacity of 210 MW, Búðarháls at 95 MW, and Vatnsfell at 90 MW. This proximity allows for enhanced grid stability and energy sharing, which is vital for maintaining a reliable power supply in this relatively isolated geographical setting. As one of the 20 total plants in Iceland, Sigalda plays a crucial role in supporting the national energy profile, which is heavily reliant on hydroelectric power. Iceland’s unique conditions, with abundant water resources and a commitment to renewable energy, result in a significant portion of the total capacity coming from hydro sources. With the global shift towards sustainable energy, Sigalda’s operational history and future potential underscore its importance in contributing to Iceland’s green energy goals. The plant’s continued operation not only supports the local economy by providing jobs but also aligns with global efforts to combat climate change through the promotion of renewable energy sources.
