3. In the event that the Balancing Services Providers representing Dispatchable RES Unit Portfolios or Dispatchable Load Portfolios should submit ISP Balancing Energy Offers and/or Balancing Capacity Bids to the HETS Operator, they must submit Non-Availability Declarations to the HETS Operator for the specific Dispatch Day.

4. Balancing Service Providers representing Balancing Service Entities, which wish to be placed under Commissioning Operation regime lasting more than four (4) hours and Balancing Service Providers representing entities under Testing Operation regime are obliged to submit to the HETS Operator preliminary Declarations of Operating Schedules in Commissioning Operation or Testing Operation at 08:00 EET for Dispatch Day, D and revised by 09:30 EET of Dispatch Day D-1. The above Balancing Service Providers have the right to submit to the HETS Operator updated schedules of Commissioning Operation or Testing Operation. The initial Declarations of Operation Schedules and the updated schedules of Commissioning Tests or Testing Operation are accepted after the approval of the HETS Operator, which is communicated to the Balancing Service Providers.

5. The above Declarations of Operation Schedules concern an entire Dispatch Day and the relevant Operation Schedule for the last hour of the specific Dispatch Day is zero. Exceptionally, the above Declarations of Operation Schedules may include a non-zero quantity at the last hour of the Dispatch Day if the Commissioning Operation or Operation Tests continue on the following Dispatch Day.

The respective Operating Schedule for Dispatchable Generating Units and Dispatchable RES Portfolios for the last mFRR Time Unit of Commissioning Trial Operation must be equal to the relevant Market Schedule for that specific Market Time Unit. The above Commissioning Operation is carried out after approval by the HETS Operator. In particular, for the Dispatchable Generation Units and the Portfolios of Dispatchable Intermittent RES Units, the above Commissioning Operation is carried out after approval by the HETS Operator if the following are cumulatively met:

   a) according to the results of the ISP for each Dispatch Period within the intended duration of the Commissioning Operation, the Generation Unit or the Portfolio of Dispatchable Intermittent RES Units is loaded at least to its Technically Minimum Generation, and

   b) after checking by the HETS Operator, no problems arise in the safe operation of the System during the intended duration of the Commissioning Operation

8. The Balancing Service Providers representing Dispatchable hydro Generating Units shall submit, if required, to the HETS Operator declarations of maximum daily energy Injection constraint in accordance with CHAPTER 7 of this Rulebook. The Regulatory Authority for Energy, Waste and Water may exercise its powers, to request and review the aforementioned declarations.

2. Minimum Available Capacity means the Technically Minimum Generation, as modified by the Balancing Service Entity.

3. Maximum Available Capacity of a Dispatchable Generation Unit means the Maximum Net Capacity, as modified on the basis of the Non-Availability Declarations and Major Outage Declarations of the Balancing Service Provider representing it. In case of Total Non-Availability, Maximum Available Capacity is zero. In case of Partial non-Availability, Maximum Available Capacity is modified on the basis of the non-Availability Declaration.

4. Available Capacity of a Dispatchable RES Units Portfolio or a Dispatchable Load Portfolio means the dispatchable capacity resulting from the Registered Characteristics of the Portfolio, as modified by the Balancing Service Provider representing it on the basis of the Non-Availability Declarations.

1. Balancing Service Providers representing Dispatchable Generating Units shall submit Techno-Economic Declarations to the HETS Operator, separately for each Balancing Service Entity.

5. The fuel cost referred to in the Techno-Economic Declarations corresponds to all costs incurred by the Balancing Service Provider for the supply of fuel irrespective of the type of individual cost factors. The cost per one unit of fuel quantity shall be calculated as if the fuel was supplied to the Balancing Service Provider by an independent third party at a uniform fuel price for each unit of fuel quantity. In case that fuel cost cannot be evidenced by documents, it shall be calculated as the ratio between the total expenses or the total cost for fuel supply, as recorded over a reasonable period of time, and the total quantity of fuel supplied to the Balancing Service Provider for the Dispatchable Generating Unit over the same period of time.

6. A Techno-Economic Declaration submitted for a Dispatchable Auto-producer Unit, shall refer only to the part of Unit Capacity that corresponds to the Maximum Net Capacity of the Unit, as defined in the Balancing Market Generating Units Registry.

1. Techno-Economic Declarations shall be submitted for each Dispatch Day, within the Deadline for Submission of the ISP Offers. For the duration of that period, Balancing Service Providers may submit Declarations for the Balancing Service Entities they represent as many times as they wish. Only the last validated Declarations shall be taken into consideration in the execution of the ISP.

2. The Techno-Economic Declaration may refer to one or more Dispatch Days. A more recent Techno-Economic Declaration shall replace the one preceding it, provided it is submitted in accordance with paragraph 1 of this Article.

3. Declarations submitted to the ISP shall be taken into consideration for the execution of ISP1, ISP2 and ISP3, as well as for any ad hoc ISP. Any submission of a Techno-Economic Declaration after the Expiration of the Deadline for Submission of ISP Offers (for the first Dispatch Day to which the Declaration refers) shall not be accepted.

The HETS Operator shall accept the Techno-Economic Declarations provided that they have been submitted in time and comply with the requirements set out in Article 10.3 and Article 10.4 of this Rulebook. In the event that a Techno-Economic Declaration does not meet the above requirements, the last legally submitted Declaration.
