The Greek Ministry of Environment and Energy has introduced a draft bill establishing detailed rules for the development of data centre projects in the country (Ministry’s statement, 10/10/2026). “With the bill, the European Directive 2024/1711 is incorporated into the national legal order and includes a series of regulations for a more transparent, more stable and fairer electricity market for the consumer”, the ministry stated.
The proposed framework includes the following measures:
- Investors in new energy infrastructure would bear the full cost of grid connections and any necessary electricity system reinforcement works directly resulting from data centre connections.
- New data centres would be required to source at least 60% of their annual electricity consumption from renewable energy sources.
- A bank guarantee of EUR200,000 per MW of planned capacity would be introduced to discourage speculative applications from projects that are not sufficiently advanced but seek to reserve available grid capacity.
- Stricter investment and environmental readiness criteria would apply to the issuance of a final connection offer.
Greek authorities have recorded a sharp increase in interest in data centre development. Applications submitted to the Independent Power Transmission Operator (IPTO or ADMIE in Greek) rose from 5 GW to 9 GW in just two months over the summer (Balkan Green Energy News, 12/10/2026).
Beyond data centres, the draft legislation also introduces changes to electricity grid connection procedures. Distribution and transmission system operators would be required to publish information on available connection capacity by region every three months.
The bill further proposes the creation of a EUR2.3bn Island Decarbonization Fund to finance projects aimed at reducing the Greek islands’ reliance on oil-fired power generation. Eligible investments would include renewable energy and energy storage facilities, among other projects.
The draft legislation is open for public consultation until 24 October 2026.
