2024, the Hellenic Electricity Distribution Net- work Operator (HEDNO) signed contracts for the deployment of 2.76 million next-generation smart meters and the development of a new central Meter Data Management (MDM) system. This initiative forms part of a broader national plan to replace all electricity meters by 2030. The new meters feature advanced capabilities, enabling real-time monitoring and remote man- agement of electricity consumption. The sup- porting MDM system – one of the most advanced globally – is expected to be fully operational by May 2026, marking a major step toward a smart- er, more transparent grid. Most notably, over 600,000 meters have already been installed, and an additional 1.1 million units are ready for roll-out. More than 55% of the country’s energy is already being remotely metered, improving both service quality and operational efficiency. This transformation also supports the growing role of prosumers – individuals or businesses who produce and consume electricity. The net- billing model, now promoted over net-metering, provides compensation based on wholesale market prices and incentivises the integration of battery storage, enhancing self-consumption and grid stability. Current regulatory trends and developments The notable regulatory trends and developments encompass the following. Energy storage Energy storage remains a key pillar of Greece’s energy transition strategy, essential for manag- ing RES curtailments and strengthening grid flexibility. While early development was driven by subsidy-based tenders, policy emphasis is
now shifting toward market-based standalone battery storage. In March 2025, a new Minis- terial Decision (GG 3354/B/2024) set out the regulatory framework for awarding Final Grid Connection Offers for standalone BESS, intro- ducing eligibility criteria, technical requirement, and anti-concentration rules. The framework establishes 4.7 GW of grid capac- ity for such systems, prioritising projects based on location, technology, readiness and links to industrial or high-consumption off-takers. To qualify, developers must demonstrate financial robustness and compliance with licensing, envi- ronmental and land-use requirements. Applica- tions are time-bound, and successful applicants must meet specific commissioning milestones to retain priority status. This new regulatory regime is expected to unlock significant investment in energy storage, signal- ling a shift toward a more open, investment-driv- en model without public subsidies. As grid con- gestion persists and RES penetration deepens, the role of standalone storage becomes increas- ingly central to Greece’s energy resilience and market stability. Bilateral PPAs PPAs are emerging as a key route for renewable energy monetisation, especially in the post-sub- sidy era. These contracts provide a mechanism for RES producers and corporate offtakers to secure long-term energy price stability, outside public tenders. Legal and financial stakehold- ers have increasingly focused on fixed-price and pay-as-produced contracts, often incorporating Guarantees of Origin (GoOs), ESG-linked claus- es and tailored settlement structures. At the end of 2024, a significant step forward was the launch of the Green PPA Platform by the
