NCC approved the Common Grid Model Methodology


National Commission for Energy Control and Prices (NCC) implementing the Commission Regulation (EU) establishing a guideline  on electricity transmission system operation approved the Common Grid Model Methodology (CGMM) which was developed by EU TSOs in cooperation with national regulatory authorities.

The CGMM serves the objective of promoting effective operational conditions of the transmission network of electricity, contributes to coordinated quality control by prescribing a common methodology for the preparation of individual grid models to be merged into the common pan-European grid model. In respect of ensuring the optimal use of transmission infrastructure, the CGMM establishes a common methodology which will allow coordinated handling of additional information related to operational arrangements, such as protection setpoints or system protection schemes and configuration of substations in order to manage operational security.

In the near future, NCC is planning to issue a decision on Common Grid Model Methodology (CGMM) prepared implementing a guideline on forward capacity allocation, which is currently being considered by all national regulatory authorities.
