For the effective implementation of the Balancing Market, the Balancing Market Rulebook is supplemented by methodologies decided by the Regulatory Authority for Energy (RAE), following a proposal by IPTO.
Methodology of Determination of the zonal and systemic Balancing Capacity needs for (a) Frequency Containment Reserve, (b) automatic Frequency Restoration Reserve and (c) manual Frequency Restoration Reserve. The Methodology is available in Greek.
Methodology used for the Settlement of the Dispatchable Load Portfolio Baseline. The Methodology is available in English.

Methodology for the calculation of Variable Cost Parameters for Thermal Production Units based on Techno-Economic data. The Methodology is available in Greek.
Methodology for estimating the HETS Losses. The Methodology is available in Greek.
Terms and Conditions of Balancing Services Providers according to Article 18 of Commission Regulation (EU) 2017/2195. Detailed description of Balancing Services Provider pre-selection procedures. The Methodology is available in English.
Terms and Conditions of Balance Responsible Parties in accordance with Article 18 of Commission Regulation (EU) 2017/2195. The Methodology is available in English.
Rules for suspension and the restoration of market activities in accordance with Article 36 of Commission Regulation (EU) 2017/2196.
This Methodology sets the rules for the settlement in the event of suspension of the market activities in accordance with Article 39 of Commission Regulation (EU) 2017/2196. The Methodology is available in English.
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, IPTO issues the following Technical Decisions, which regulate details in technical issues with non-regulatory content. The Technical Decisions are issued following a public consultation and are posted on the website of IPTO. In the event of any contradiction between the provisions of the Balancing Market Rulebook and the corresponding Technical Decisions, the provisions of the Rulebook shall prevail.
The Technical Decision "Procedures of registration with the HETS Operator Registry" provides detailed description of application, submission and registration procedures in the HTS Operator Registries. The procedures are analytically presented in section Registration Procedures.
The Technical Decision is available in English.

Details on the implementation of the manual FRR (mFRR).
Details on the implementation of the automatic FRR (aFRR).
Details and examples of calculations regarding the clearing of the Balancing Energy Market, the Balancing Capacity Market and the Imbalances.
Details on the implementation on Integrated Scheduling Process.
Numerical values of the Minimum and Maximum Prices of Balancing Capacity and Balancing Energy Offers, which are imposed for technical reasons. The Technical Decision is available in English.
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.
For the calculation of the Instructed Energy, a tolerance limit is set per category of Balancing Service Entity at 2%. The Decision of RAE is available in Greek.
The Balancing Energy Deficit Premium price in €/MWh is determined by RAE, following a proposal by IPTO. RAE's Decision No 1226/2020 (GG Β' 4033/21.09.2020) is available in Greek.
If during an Imbalance Settlement Period energy from Contracted Units or Supplementary Energy from Emergency Imports was injected, or Load Cuts were performed, the upward Balancing Energy Price for manual FRR may be increased at least up to the level of € 2.100 /MWh for the specific Imbalance Settlement Period. In the event that the upward Balancing Energy Price for manual FRR receives a value greater than € 2,100 / MWh, then the value of the Balancing Energy Deficit Premium price is zero (0).

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 shall be determined for each Dispatchable hydro Generating Unit by RAE following a proposal of the relevant Balancing Service Provider and an opinion of the HETS Operator.
