New Rules for the Electricity Market and Grid Operation

Europe’s electricity networks are currently operated according to national rules that govern the actions of operators and determine how access is given to users. The European Union is adopting a common set of rules, commonly known as Network Codes, which will enable electricity network operators, generators, suppliers and consumers to operate more effectively in the pan-European electricity market. The harmonisation of national rules will promote the efficient use of cross-border interconnection between countries and will provide a more secure and reliable electricity system with an increased level of renewable generation.

Over the past several years we, together with other members of ENTSO-E, have been working hard to develop the Network Codes. The final rules are proposed by the European Commission and adopted by the European Parliament before becoming binding European law. The focus now is to identify what necessary changes are required in Ireland and Northern Ireland to ensure that our national legislation is compliant to these new rules when they begin to enter into force.

A substantial amount of work has already been achieved to prepare for these new rules, including the new design of the Integrated Single Electricity Market (I-SEM). We continue to work with our regulators, governments and key stakeholders to ensure timely delivery.  

Network Codes and Guidelines

The current European Electricity Network Codes and Guidelines are as follows:

Consultations

A number of consultations will be held prior to the submission of proposed new local, regional and European rules.

For European and Regional consultations please visit the ENTSO-E consultation hub.

Local consultations related to the Network Codes are shown below.

07.04.17 The Network Code Requirements for Generators (RfG) is one of three Connection Codes which form part of the European Network Codes. It seeks to provide a clear legal framework for grid connections and facilitate electricity trading whilst ensuring system security, facilitating the integration of renewable energy and ensuring a more efficient use of the network.

RfG ‘entered into force’ on 17 May 2016, and applies to generators that conclude a final and binding contract for the purchase of their main generating plant after 17 May 2018.

The RfG defines the requirements applicable to new generators with a maximum capacity of 800 W or greater. Generators are placed into one of four ‘type’ categories A-D which determines technical capabilities to support System Operators.  As part of the national implementation of RfG, the relevant TSO of each member state needs to set banding thresholds. TSOs can either apply the maximum MW boundaries as defined in the RfG or, where it is reasonable, choose lower values. This consultation describes the EirGrid proposal for applying the boundaries as defined in the RfG.

We look forward to receiving your feedback and using it to improve our proposal. Please email your submission by 15/05/2017 to GridCode@eirgrid.com with the subject title “RfG Banding Threshold Consultation - Ireland”.

Download the consultation document here.

14.07.17 The TSO has considered the responses to the RfG Banding Threshold Consultation as published on 7 April 2017 and has issued a Minded-To Position Paper that can be downloaded here.

 

29.11.2017 This public consultation is a proposal for the determination of Load Frequency Control blocks in accordance with Article 6 (3) (g) and Article 141(2) of Commission Regulation (EU) 2017/1485 establishing a guideline on electricity transmission system operation.

This public consultation document is produced jointly by EirGrid plc in its role as the Transmission System Operator in Ireland and SONI Ltd. in its role as the Transmission System Operator in Northern Ireland.

This consultation applies to the synchronous area that spans Ireland and Northern Ireland.

Responses should be submitted to EirGrid and SONI at gridcode@eirgrid.com before 5pm on 8 January 2018.
