EYDAP sourced 73.47% of its total energy consumption from renewables in 2025, up from 61.05% in 2024, according to the Sustainability Statement in its FY2025 annual report.
A shift in purchased energy
Purchased energy from fossil sources fell from 117,414.77 MWh in 2024 to 82,480.71 MWh in 2025, while purchases from renewable sources rose from 31,997.04 MWh to 79,804.49 MWh. Market-based greenhouse gas emissions fell from 236,597.39 to 209,635.48 tCO2eq. Location-based emissions were almost unchanged at 268,987.18 tCO2eq in 2025, while total energy consumption rose to 337,129.77 MWh.
New generation in the pipeline
In the first half of 2026 EYDAP completed the tender for seven photovoltaic stations totaling 9.72 MW, and two of them were under construction at Acharnes and Polydendri. A producer certificate was issued for a 13.99 MW biogas plant at the Psyttalia wastewater treatment plant. A new 18-month electricity supply contract requires 50% of supply to be covered by renewable guarantees of origin. The H1 2026 report does not state the cost or completion dates of the photovoltaic stations.
What is already running
The Psyttalia plant already runs two biogas combined heat and power units totaling 11.4 MWe, alongside a 12.9 MWe natural gas unit, and EYDAP operates five small hydroelectric stations on its aqueducts. Water recycled and reused reached 18,178,007.50 m3 in 2025, against 17,103,240.50 m3 in 2024.
How energy fits into EYDAP's 2025–2029 regulatory settlement, what its €2.5 billion investment plan for 2026–2035 funds, and which milestones fall due before 2029 are set out in the report.
