Summary
Details
- Greece
Law 4951/2022 is binding for RES/CHP developers and storage project sponsors that use the licensing pathways it establishes.
In-scope entities must:
Submit correct technical, financial and legal documentation through the updated process.
Comply with grid connection requirements and any market participation obligations tied to the project category.
Respect milestone deadlines to avoid loss of permitting or priority status.
Exceptions:
Certain small-scale self-consumption projects may fall under simplified procedures (depending on size and connection type), while larger projects follow the full pathway.
Island/isolated systems may have adapted rules depending on interconnection status.

What’s Required
Law 4951/2022 modernises and accelerates the second phase of licensing for renewable energy (RES) and high-efficiency cogeneration projects, focused on the period from grid connection application to operation permit. It also introduces a national framework for electricity storage licensing and provides for pilot marine floating PV.
Typical compliance actions include:
Following the updated grid connection and licensing sequence, including required submissions to network administrators.
Meeting deadlines and conditions attached to connection offers and operation permits.
For storage projects, complying with the licensing route and technical/market rules established for stand-alone or hybrid storage.
Important Deadlines
Enacted in July 2022.
Project-specific milestones apply (connection offer validity, construction, and commissioning windows), typically set by permits and regulatory decisions.
Current Status
The law is in force and is widely treated as a key reform to reduce RES licensing timelines while enabling electricity storage deployment as a distinct regulated asset class.
Penalties for Non-Compliance
Loss of licensing advantages or the underlying permit/connection rights if milestone conditions are not met.
Administrative sanctions under energy regulation for failures to comply with licensing, grid, and technical rules (often applied via regulator and operator decisions).
Examples of Known Violations
Most issues observed in practice relate to missed milestone deadlines, incomplete documentation, or inability to satisfy grid connection requirements due to network constraints rather than “named penalty cases.”
