November 27 (Renewables Now) - Enefit Green, part of Estonian state-owned energy company Eesti Energia AS, has built on the island of Ruhnu in the Baltic Sea a power system relying on wind and solar energy with some backup.
The firm has installed a solar farm, a battery for energy storage and a diesel generator running on biodiesel near Ruhnu airfield. To the west of the airfield the company has also erected a small wind turbine. Enefit Green has invested a total of EUR 500,000 (USD 567,000) in the project, according to a statement by its parent company.
“We now produce at least 50% of electricity consumed on the island from renewable energy sources,” said Aavo Kärmas, CEO of Enefit Green. This is expected to at least halve the carbon dioxide (CO2) that is emitted through electricity generation on the island, previously amounting to 500 tonnes per year, according to Kärmas.
The CEO further said that the company is ready to consider deploying similar renewable energy solutions on other small Estonian islands. The island of Ruhnu has a total area of about 12 sq km (4.6 sq m) and a population of 60 people, except during the summer season when this number can grow to 170. Ruhnu’s total annual power consumption is estimated at around 450 MWh.
