Greece’s Astypalea Island to Go Green With New Hybrid Solar and Storage Plant by PPC
PPC Starts Work on Hybrid Solar-Storage Project in Astypalea to Power 80% of the Island
Greek utility PPC Group has officially broken ground on a hybrid solar and battery energy storage system (BESS) on the island of Astypalea, aiming to cover more than 80% of local electricity demand with clean energy and significantly reduce CO₂ emissions.Once operational by late 2025, the new plant is expected to eliminate 5,700 tonnes of CO₂ annually and replace Astypalea’s reliance on oil-powered electricity generation.
Details of the Hybrid Installation
The project combines a 3.53 MW bifacial solar array with a 14.12 MWh battery storage system, designed to generate approximately 6.55 GWh of clean electricity per year. The system will have a maximum storage absorption capacity of 8 MW, ensuring stable year-round power—even during the summer months when the island’s population swells due to tourism.Over 6,000 bifacial solar panels will be installed on-site, using dual-sided technology to capture sunlight from both sides for higher efficiency.
Decarbonizing Greece’s Islands
This initiative is part of PPC’s broader strategy to decarbonize Greece’s non-interconnected islands, following the successful launch of its hybrid energy system on Ikaria Island.“The pioneer pilot hybrid project of PPC Group on Astypalea can serve as a case study for the energy future of our country,” said Konstantinos Mavros, Deputy CEO for Renewables (RES).
Storage as a Key to Renewable Stability
The project highlights the crucial role battery storage plays in addressing renewable intermittency and ensuring energy security for remote and seasonal regions.It aligns with PPC Group’s 2025–2027 investment strategy, which includes 600 MW of upcoming battery storage projects and two major pumped hydroelectric plants under development in Western Macedonia.
