Grid Code Version 15
The Grid Code is a technical document that forms the rules around operating, maintaining and developing the transmission system. It also sets out the procedures for overseeing the actions of all transmission system users.

This document has been published by the TSO to provide clarity on the electromagnetic transient (EMT) modelling requirements for Converter-based Reactive Support Systems in Ireland, as specified in Grid Code clause PC.A8 (Modelling Requirements for Users) [1.].
EirGrid EMT model specification Synchronous Condenser Units (July 2025)
This document has been published by the TSO to provide clarity on the electromagnetic transient (EMT) modelling requirements for Synchronous Condenser Units (SCU) in Ireland, as specified in Grid Code clause PC.A8 (Modelling Requirements for Users) [1.].
EirGrid EMT model specification Synchronous Generator (July 2025)
This document has been published by the TSO to provide clarity on the electromagnetic transient (EMT) modelling requirements for Synchronous Generator Plants in Ireland, as specified in Grid Code clause PC.A8 (Modelling Requirements for Users) [1.], in compliance with European legislation EU 2016/631 reflected in the Network Code for grid connection of generators (Requirements for Generators (RfG) [2.]).
EirGrid EMT model specification Wind Power Plants (July 2025)
This document has been published by the TSO to provide clarity on the electromagnetic transient (EMT) modelling requirements for Wind Power Plant Modules (PPM) in Ireland, as specified in Grid Code clause PC.A8 (Modelling Requirements for Users) [1.], in compliance with European legislation EU 2016/631 reflected in the Network Code for grid connection of generators (Requirements for Generators (RfG) [2.]).
