System Operation Guidelines
Commission Regulation (EU) 2017/1485 established a guideline on electricity transmission system operation.
What is this guideline?
The System Operation Guideline (SOGL) works to ensure system operations are safe and coordinated across Europe. It standardises system security, operational planning and frequency management standards.

Proposals and consultations
Consultations are held before the submission of proposed new local, regional and European rules. Below shows local consultations in Northern Ireland on the System Operation Guideline (SOGL). For European and regional consultations, visit the ENTSO-E consultation hub.
Coordinated Security Analysis (CSA)
Coordinated security analysis is important for protecting the power system. Grid incidents in one area may have consequences for neighbouring zones. Article 75 and 76 details coordinated security analysis to protect the power system.
Below shows the progress of our consultation on IU Regional Operational Security Coordination (ROSC) methodology. The IU region is made up of SONI, EirGrid and National Grid ESO.
Relevance of Assets for Outage Coordination (RAOC)
It's vital that we have plans in place to safeguard the operational security of the grid. That's why we need to standardise the outage coordination process on a regional level. This includes the assets we'll use in the event of an outage.
Key Organisational Requirements, Roles and Responsibilities (KORRR)
Article 40(6) of SOGL focuses on data exchange. It requires all TSOs to agree on key organisational requirements, roles and responsibilities (KORRR). KORRR was approved by the All Regulatory Authority on 19 December 2018.
It's the basis for what TSOs, DSOs and Significant Grid Users (SGUs) must do to comply with Articles 41 to 53 of SOGL. As part of KORRR, the TSO must coordinate with DSOs and SGUs on the applicability and scope of data exchange. They must also agree the processes and formats of data exchange between them.
KORRR requirements apply to new and existing SGUs. You can refer to Article 2(1) of SOGL for a definition of a SGU.
Synchronous Area and Load Frequency Control Blocks
The SOGL requires that TSOs of each synchronous area are responsible for operating load frequency control and reserves. This means we had to develop proposals for a Synchronous Area Operational Agreement (SAOA) and the LFC Block Operational Agreement (LFCBOA).
