Halki is a small Greek island with 250 inhabitants deep in the south of Europe.

Its solar-powered electricity grid is the first fruit of the GR-eco Islands project.

Within that framework, in 2021 an energy community was established to support the social economy. Several French and Greek companies have invested in it.

A solar park is now producing 1.8 gigawatts of electricity per year.

“The project is estimated to reduce the CO2 footprint by 2,576 tonnes, which is the equivalent of the emissions of 617 conventional cars,” says Vassilis Zafiropoulos, project developer with Akuo.

“At the same time €260,000 euro have been saved on the production of the green energy, which is an amount sufficient to cover the cost for over 200 families that live on the island.”
