“ The Letters of Guarantee under the light of the Law 5151/2024”
(article by Panagiota Maragkozoglou – Associate and Andriani Kantilieraki – Senior Associate published on Lexology, January 29, 2025)
The new Greek law 5151/2024 introduces significant modifications to the legislative framework concerning letters of guarantee required for the development of Renewable Energy Sources (RES) projects, particularly for grid connection.
Key provisions include:
- Return of Letters of Guarantee: RES and High-Efficiency Combined Heat and Power (HE CHP) plants can request the return of specific letters of guarantee if they have received a binding connection offer but have not been selected in competitive procedures or applied for an operational aid agreement by October 2024. Previously, returns were allowed under very limited conditions.
- Reduction of Letters of Guarantee: RES and hybrid plants can replace their letters of guarantee with a reduced amount (30% reduction for plants ≥1 MW, 15% for plants <1 MW) if they have submitted them before October 31, 2024, or if applying afterward. Hybrid plants on non-interconnected islands must submit these guarantees upon accepting the connection offer.
- Abolition of Exemptions: Plants with a maximum production capacity of up to 0.5 MW must now submit a producer’s certificate letter of guarantee, a requirement previously waived. Both existing and pending applications must comply within three months.
This law modernizes the framework, easing financial burdens for developers while maintaining regulatory oversight.
