Implementation of European regulations

ELES as the transmission system operator of the electric power network is in accordance with the legislation obliged to notify the public about the procedures of adoption and implementation of European regulations in the field of electric power transmission.

NRA approvals and adopted documents

Italy North TSOs proposal for fallback procedure

Document  is a common proposal developed by all Transmission System Operators within the Italy North Capacity Calculation Region regarding the proposal for fallback procedures in the event that the single day-ahead coupling process is unable to produce results. This proposal is required by Article 44 of Regulation (EU) 2015/1222 on Capacity Allocation and Congestion Management (CACM Regulation).
As required under Article 44 of the CACM Regulation, each TSO of Italy North Capacity Calculation Region, in coordination with all the other TSOs, shall develop a proposal for robust and timely fallback procedures to ensure efficient, transparent and non-discriminatory capacity allocation in the event that the single day-ahead coupling process is unable to produce results within the Italy North Region. This procedure shall apply to all relevant borders of Italy North Region.
Shadow Auction Rules are the Annex to the proposal.

The Energy Agency approved the proposal on 19.10.2017.

Italy North TSOs proposal for design of Long Term Transmission Rights

Document is the Italy North CCR TSOs’ long-term transmission rights proposal required by Article 31 of the FCA regulation. In line with this article TSOs of a capacity calculation region, where long-term transmission rights exist, to jointly develop a proposal for the regional design of long-term transmission rights to be issued on each bidding zone border within the CCR.

The Energy Agency approved the proposal on 19.10.2017.

Core CCR TSOs’ proposal for the regional design of long-term transmission rights

Document is the Core CCR TSOs’ long-term transmission rights proposal required by Article 31 of the FCA regulation. In line with this article TSOs of a capacity calculation region, where long-term transmission rights exist, to jointly develop a proposal for the regional design of long-term transmission rights to be issued on each bidding zone border within the CCR.

The Energy Agency approved the proposal on 19.10.2017.

All TSOs’ proposal for the establishment of a Single Allocation Platform (SAP)

Document is the common proposal developed by all Transmission System Operators for a set of requirements and for the establishment of the Single Allocation Platform in accordance with Article 49 and for a cost sharing methodology in accordance with Article 59 of Commission Regulation (EU) 2016/1719 establishing a guideline on Forward Capacity Allocation (FCA Regulation).
The SAP Proposal lays down the functional requirements, governance, liabilities and cost sharing methodology for the Single Allocation Platform. The SAP shall be able to perform, at least, the execution of the long-term auctions in accordance with the valid Harmonised allocation rules for long-term transmission rights (HAR) and any associated additional tasks required in the provision of long-term auctions (such as clearing and settlement and on call support) as described in Article 50 of the FCA Regulation.
All TSOs agree to use JAO as the SAP Operator and shall ensure through the SAP Operator, as a vehicle of cooperation, that the SAP is operational and complies with the functional requirements of this SAP Proposal, the HAR and the FCA Regulation.

The Energy Agency approved the proposal on 11.12.2017.

All TSOs’ proposal for the day-ahead firmness deadline (DAFD)

Document is a common proposal developed by all Transmission System Operators regarding the development of a day-ahead firmness deadline (DAFD) in accordance with Article 69 of Commission Regulation (EU) 2015/1222 establishing a guideline on Capacity Allocation and Congestion Management (CACM Regulation).
Article 2(35) of the CACM Regulation defines the DAFD as “the point in time after which cross-zonal capacity becomes firm”. The DAFD shall be sixty (60) minutes before the day-ahead market gate closure time.

The Energy Agency approved the proposal on 13.6.2017.

Common Grid Model Methodology (CGMM)

The purpose of the methodology is to describe the requirements and procedures for the preparation of the so-called Individual Grid Model (IGM) by each individual transmission system operator, which will facilitate the calculation of cross-border capacities and operational security analyses. Target time-frames subject to these models are: “D-2”, ”D-1” and “ID”. In individual grid models (IGM) the elements of the transmisison system have to be modelled on the 220 kV or higher voltage levels. For the preparation of IGM models, generation forecast, forecast of load and planned outages for the target date must be considered. ELES already considers and uses the requirements of the methodology at the preparation of “D-2”, ”D-1” and “ID” models. Until now, model preparation and consideration of input data was left to the judgement of each individual system operator, the new methodology lays down detailed standards that must be considered by all system operators.

With current models, ELES already fulfils the methodology requirements, therefore, additional harmonisation of our current processes is not required with regard to the proposed methodology.

In June 2017 ENTSO-E released Common Grid Model methodology as requested in FCA GL on the basis of methodology requested in CACM GL, that has already been approved by national regulatory authorities.

Generation and load data provision methodology (GLDPM)

The GLDPM methodology is closely connected with the CGM methodology, since it stipulates the requirements and procedures with regard to input data for the preparation of IGM models. The methodology lays down a requirement that all generators connected to the 220 kV level or higher voltage levels, must be modelled in detail in the IGM model. Other generators on lower voltage levels can be modelled on an aggregate basis. Production units, modelled in detail and aggregated, must be separately modelled with regard to the primary energy source.

The methodology also determines that all loads connected to the 220 kV level or higher must be modelled in detail. Other loads are modelled as aggregated loads. Because the Slovenian transmission system has no loads that would be directly connected to 220 or 400 kV voltage level, loads are modelled as the aggregation by individual substations. The connecting point in the model as well as active and reactive power must be provided for such loads.

This methodology does not bring significant changes for ELES in already established daily processes.

Slovenian NRA approves the submitted GLDPM methodology on 11 Januray 2017.

In June 2017 ENTSO-E released Generation and Load Data Provision methodology as requested in FCA GL on the basis of methodology requested in CACM GL, that has already been approved by national regulatory authorities.
