The Day-Ahead and the Intra-Day Markets do not take into account the technical constraints of the Balancing Service Entities, whereas the Balancing Market (both the Integrated Scheduling Process and the real time Balancing Energy Market) does so. In case the Market Schedule (DAM and IDM schedule) of any Balancing Service Entity violates its technical constraints, this specific Market Schedule is infeasible, as the ISP Schedule and the Balancing Market Schedule will necessarily differ from the Market Schedule. In such cases, the difference in relation to the Market Schedule will not be considered as Balancing Energy, but as an Imbalance.

The Infeasible Market Schedule Calculation Methodology determines the Dispatch Periods during which, due to a Market Schedule being infeasible, the difference between the energy injected / offtaken by the Balancing Service Entities and the corresponding Market Schedule is considered as Imbalance. The Methodology is available in Greek.

For the effective implementation of the Balancing Market, the Balancing Market Rulebook is supplemented by special approvals and parameters provided for in this Rulebook, which are approved by the Regulatory Authority for Energy (RAE) following a proposal by IPTO.

Interested parties that wish to register in the HETS Operator Registry shall submit a registration fee, as described in section Registration Procedures. The Registration fee is determined by decision of RAE.

Registration Fee in HETS Operator Registry
One-off charge for Balancing Service Providers or/and Balance Responsible Parties: 2.000€
One-off charge for Balancing Market Generating Units: 2.500€
*The registration fee is paid only once, in case the interested party bears both the attribute of a Balancing Service Provider and Balance Responsible Party.

The Safety Maximum Reservoir Level is the the maximum level per reservoir, above which the Dispatchable Hydro Generating Units connected to the Reservoir may submit mandatory hydro injection declarations to avoid overflow.

The Safety Minimum Reservoir Level is the minimum level per reservoir, above which the Dispatchable Hydro Generating Units connected to the Reservoir may submit declarations of maximum daily energy injection constraint. 

The height of the Safety Maximum Reservoir Level and the Safety Minimum Reservoir Level are determined for each Dispatchable hydro Generating Unit by RAE's Decision 1392/2020 (GG Β' 4703/23.10.2020).
