The Greek island of Sifnos has announced its plan to become the first in the Cyclades archipelago to generate 100% of its electricity from renewable sources. The Sifnos Energy and Development Cooperative has filed an application with the Greek Energy Regulatory Authority (RAE) for a hybrid power plant and conducted research in collaboration with the Greek Mediterranean University of Crete, Mind.ua reports.
Wind and pumped-storage hydroelectric power stations will be connected on the island. The main role will be played by four wind turbines with a capacity of 3 MW each, and excess electricity will be accumulated in a pumped storage station. It will be designed to provide a maximum consumption of 860 MW or 16 days of average consumption in the Aegean island. This system can be further enhanced by a solar power plant.
For electricity production, when the electricity demand will exceed the capacity of the wind farm (for example, in light winds, seawater will be used.
The share of the expected surplus from the annual output of the wind farm is estimated at more than 40%. It can be used for desalination and the production of "green" hydrogen for refuelling ships. The authors of the project called on the Greek government to support it, stating that it will pay off in 8 years.
Greece plans to transform lifestyles in several small islands with projects in renewable energy and energy efficiency, digitalization and electric transport. They are now largely dependent on diesel-fueled generators, and electricity bills on the islands are subsidized.
