This section presents:

a) the exchange of information between the Day-Ahead Market and the Intra-Day Market on the one hand and the Balancing Market on the other,

b) the procedure and the conditions for the submission of a Total or Partial non-Availability Declaration by the Balancing Service Providers for the Balancing Service Entities they represent,

c) the procedure for the submission of a Techno-Economic Declaration by the Balancing Service Providers for the Balancing Service Entities they represent,

d) the procedure for the submission of ISP Balancing Energy Offers by the Balancing Service Providers for the Balancing Service Entities they represent,

e) the procedure for the submission of Balancing Capacity Offers by the Balancing Service Providers for the Balancing Service Entities they represent, and

f) details on the implementation of the Integrated Scheduling Process (ISP).

1. ISP aims to (a) commit the Balancing Capacity needed in the short term and (b) to achieve a schedule that shall meet the technical constraints of the HETS and the Balancing Service Entities based on ex ante estimation of any HETS Imbalances.

2. All procedures and actions related to ISP shall refer to a specific Dispatch Day D.

3. The Dispatch Day to which the ISP refers, coincides with the Delivery Day of the Day- Ahead Market and the Intra-Day Market. Dispatch Day D shall start at 01:00 EET of calendar day D and shall end at 01:00 EET of calendar day D +1.

4. A Dispatch Day consists of individual Dispatch Periods. The duration of each Dispatch Period is set at half an hour. The first Dispatch Period of Dispatch Day D is 01:00 – 01:30 EET.

5. The ISP shall be executed at three scheduled times:

   a) one (ISP1) which shall be executed at 16:45 EET on calendar day D-1 and shall cover all Dispatch Periods of Dispatch Day D,

   b) one (ISP2) which shall be executed at 00:00 EET on calendar day D and shall cover all Dispatch Periods of Dispatch Day D, and

   c) one (ISP3) which shall be executed at 12:00 EET on calendar day D and shall cover the last twenty-four (24) Dispatch Periods of Dispatch Day D,

6. The HETS Operator may execute the ISP at any time for all or for certain Dispatch Periods ("ad-hoc ISP”), in the event of an occurrence which significantly affects the scheduling of the Balancing Service Entities and the dispatch of the Balancing Capacity. Such events include but are not limited to, significant changes in the zonal Load Forecast, or zonal RES Units Forecast, or the availability of resources, or the HETS conditions.

7. The following products shall be used in the ISP:

   a) upward and downward Balancing Energy without distinction between mFRR and aFRR;

   b) the following Balancing Capacity products:

   1. Upward and downward FCR,

   2. Upward and downward aFRR, and

   3. Upward and downward mFRR.

8. The submission of Balancing Capacity Offers and ISP Balancing Energy Offers by Balancing Service Providers to the ISP, for Dispatch Day D shall start at 14:00 EET on calendar day D-1 and shall end at 16:45 EET on calendar day D-1. During this time period, the Balancing Service Providers may submit Offers for the Balancing Service Entities they represent, as many times as they wish. Only the last validated Offers shall be taken into consideration in the execution of the ISP.

9. The Deadline for the Submission of ISP Offers is set at 16:45 EET.

10. The HETS Operator shall draw up a timetable for the activities governing the actions required for the execution of the ISP, which shall include the actions required during calendar days D and D-1. This schedule is set out in the Technical Decision pertaining to the Integrated Scheduling Process.

11. Details on the ISP are provided in the Technical Decision: “Integrated Scheduling Process”.

1. The Energy Exchange shall transmit details of each Market Time Unit for each Dispatch Day to the HETS Operator delivered within 20 minutes of the final deadline for submission of bids in either the Intraday Auction or Continuous Intraday Trading, containing the following information:

   a) The Scheduled Energy Exchanges and the corresponding purchase prices, for each inter-zonal corridor, as calculated in the results of the Day-Ahead Market and the Intra-Day Market.

   b) The Market Schedules, i.e. the algebraic sum of the energy volumes of the accepted Day-Ahead and Intra-Day Market Orders per Market Time Unit of the Dispatch Day for each of the following Entities:

   1. Dispatchable Generating Units in normal operation,

   2. Dispatchable Generating Units in Testing Operation:

   3. generating units in Commissioning Operation,

   4. Dispatchable RES Units Portfolios per Bidding Zone in normal operation,

   5. Dispatchable RES Units Portfolios per Bidding Zone in Testing Operation,

   6. Non-Dispatchable RES Units Portfolios per Bidding Zone in normal operation,

   7. Non-Dispatchable RES Units Portfolios per Bidding Zone in Testing Operation or in Commissioning Operation,

   8. RES Units Portfolio without Market Participation Obligation per Bidding Zone,

   9. Load Portfolios per Bidding Zone,

   10. Dispatchable Load Portfolios per Bidding Zone,

   11. Pumping load from Dispatchable Pumped Storage hydro Generating Units.

   c) The Market Schedules related to the HETS Losses per Bidding Zone, as calculated in the results of the Day-Ahead Market and the Intra-Day Market.

2. The Distribution Network Operators shall notify the HETS Operator as soon as possible in case of disconnection:

   a) of any component of the Distribution Network that may affect the normal operation of the HETS in real time,

   b) of any load connected to the Distribution Network which may affect the zonal Load Forecast performed by the HETS Operator in the context of the Balancing Market operation, and

   c) of any RES Unit connected to their Distribution Network, which may affect the zonal RES Forecast performed by the HETS Operator in the context of the Balancing Market operation.

3. The Distribution Network Operators shall immediately notify the HETS Operator, on justifiable grounds, if they plan to have a load curtailment or any other Network operations that are expected to cause a decrease in load in excess of ten (10) MW at a specific point of connection to the HETS.

4. The Load Representatives that have submitted a Buy Order to the Electricity Markets managed by the Energy Exchange are obliged to immediately notify the HETS Operator of any possible changes in the energy volumes that correspond to the load meters they represent. The Load Representatives that have not submitted a Buy Order to the Electricity Markets managed by the Energy Exchange for load meters they represent on the Dispatch Day in question, in accordance with the Meter to Load Representative Correspondence Table as defined in the HETS Grid Code, are obliged to notify the HETS Operator of any possible changes in the total load they expect those load meters to offtake for each Dispatch Period of the Dispatch Day.

5. The RES Producers and / or RES Aggregators representing RES Units Portfolios, shall submit injection forecasts for each Dispatch Period of the Dispatch Day no later than two (2) hours prior to the execution of each scheduled ISP.
