PPC Group has begun building a hybrid solar and storage project on the Greek island of Astypalea, aiming to cover over 80% of local energy needs and cut 5700 tonnes of CO₂ annually.
The plant will combine a 3.53MW solar array with a 14.12MWh battery energy storage system and is expected to generate 6.55GWh per year once commissioned by end-2025.
The initiative is part of PPC’s strategy to decarbonise non-interconnected islands and replace oil-fired power with renewables, following the success of its Ikaria hybrid energy project.
Deputy CEO for RES Konstantinos Mavros said: “The pioneer pilot hybrid project of PPC Group on Astypalea can serve as a case study for the energy future of our country.”
The system will include 6000 bifacial solar panels and a maximum storage absorption capacity of 8MW.
The installation will support year-round supply on the island, which sees a seasonal population surge due to tourism.
PPC said the project enhances energy security and demonstrates the role of storage in tackling renewable intermittency.
The company currently owns 6.2GW of renewables across Greece, Italy, Romania and Bulgaria, with a target of 11.8GW by 2027.
Its 2025–2027 investment plan includes 600MW of battery projects and two large pumped hydro plants under development in Western Macedonia.
