Italy North TSOs proposal for coordinated redispatching and countertrading methodology

On 24th May 2019 the Energy Agency issued consent to the Italy North TSOs proposal for coordinated redispatching and countertrading methodology in accordance with Article 35 of the Commision Regulation (EU) 2015/1222 of 24 July 2015 establishing a guideline on capacity allocation and congestion management.

Complementary Regional Intraday Auctions proposal for Italy North Capacity Calculation Region (CRIDA)

Document or “CRIDA proposal”, is a common proposal developed by Nominated Electricity Market Operators and the Transmission System Operators of Italy North Capacity Calculation Region for the design and implementation of Complementary Regional Auctions according to Article 63 of Regulation (EU) 2015/1222 on Capacity Allocation and Congestion Management. The Proposal takes into account the congestion income distribution methodology in accordance with Article 73 of the CACM Regulation and the general principles of congestion income use in Article 16 (6) of Regulation (EC) No 714/2009 of the European Parliament and of the Council of 13 July 2009 on conditions for access to the network for cross-border exchanges in electricity.

The Proposal includes the implementation of continuous energy trading mechanism accommodating the implicit allocation of the intraday cross-zonal capacity and the implementation of Complementary Regional Intraday Auction Mechanism on Italy North CCR.

The Energy Agency approved the proposal on 4.6.2019.

All TSOs’ proposal for a Methodology for Calculating Scheduled Exchanges resulting from single day-ahead coupling

Document provides a methodology for calculating Scheduled Exchanges resulting from the SDAC (”hereafter referred to as ”DA SEC Methodology”) in accordance with Article 43 of Commission Regulation (EU) 2015/1222 establishing a guideline on Capacity Allocation and Congestion Management. The DA SEC Proposal, in line with Article 45 of CACM Regulation, accommodates situations where there are more than one Nominated Electricity Market Operator (hereafter referred to as “NEMO”) designated and/or offering day-ahead trading services in a particular geographic area. The DA SEC Proposal shall consider situations where the bidding zone is equal to the scheduling area, as well as where there are multiple scheduling areas within a bidding zone.

The DA SEC Proposal provides for the calculation of Scheduled Exchanges between bidding zones, scheduling areas and NEMO trading hubs.

The Energy Agency approved the proposal on 13.3.2019.

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.

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.

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.
