QINOUS storage system Q! CompactL on Ruhnu.

The Estonian island of Ruhnu is already popular with Baltic Sea lovers – for good reasons, such as its picturesque, easily accessible beaches and its first class sailing area. On the highest point of the island stands a four-legged lighthouse, which was prefabricated in France in 1877. The design stems from none other than Gustave Eiffel, the architect of the Eiffel Tower in Paris.

The Ruhnu wooden church, built in 1644, is one of the oldest wooden buildings in Estonia. The adjacent stone Lutheran church from 1912 is today the place of worship.

And now Ruhnu can serve as a model for other European islands – in terms of energy supply, which is based on a QINOUS storage system.

The entire electricity consumed on the island – around 450 megawatt hours per year – was previously produced by a diesel generator. Enefit Green, part of the Estonian Eesti Energia Group, has invested around 500,000 euros in the combined solar wind diesel battery storage system, which was officially inaugurated on 23rd November 2018. Enefit Green leader Aavo Kärmas praises the smart Microgrid solution: „More than half of the electricity required on the island is generated from renewable sources.“

QINOUS engineer Maik Barth, who installed and commissioned the Q! CompactL storage system on Rhunu island, sums up: „I wish the islanders a bright and warm winter in their homes and hope that they show their many guests our energy storage system. Thank you for the exceptional hospitality during the installation“.
