Description

Kea is interconnected with the mainland through high voltage. More specifically, the island is connected at the area of Lavrio of Attiki, with two submarine cables (3x150 Al, 20 kV).

Kea, also known as Tzia, is a Cycladic island in the Aegean Sea and the closest inhabited Cycladic island to Attica. It is the 6th largest and the 10th most populous island in the Cyclades. Kea covers an area of 131 square kilometres and has 88 kilometres of coastline. The highest peak is Prophet Elias, reaching 568 meters. The island also features one of the largest natural harbours in the Mediterranean, the Bay of Agios Nikolaos.

Kea’s energy system is fully interconnected with the mainland, allowing it to benefit from Greece’s broader energy mix, which currently includes 57% renewable energy sources. In addition, the island is taking further steps to increase local renewable energy production, with 1325 kW of solar PV and 60 kW of onshore wind already installed. The island's annual energy demand is around 70 GWh, highlighting the need for more sustainable energy solutions to reduce dependence on conventional power sources and lower carbon emissions.

With a growing interest in sustainability, Kea is actively working towards improving its environmental footprint through clean energy initiatives and mobility solutions. In the Follower Islands programme framework, Kea aims to enhance its energy transition by focusing on sustainable transportation and increased use of green fuels. The municipality plans to replace half of its public transportation fleet with electric vehicles and introduce a shared bicycle system to promote eco-friendly mobility. Key projects such as the National Energy and Climate Plan, the Sustainable Urban Mobility Plan (SUMP), and the Electric Vehicle Charging Plan (EVCP) are being implemented to support these goals. Kea seeks to become a model for energy-efficient and environmentally responsible island communities through these initiatives.
