NCC approved the Common Grid Model Methodology


​National Commission for Energy Control and Prices (NCC) implementing the Commission Regulation (EU) establishing a guideline on capacity allocation and congestion management 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 competition in the generation, trading and supply of electricity in contributing to coordinated capacity calculation 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 by which the common grid model is established, which will allow determinations to be made regarding the optimum availability of the transmission grid and thus, the optimal use of the transmission infrastructure.

The creation of the common grid model and use thereof in the capacity calculation process will optimise the calculation and allocation of cross-zonal capacity by ensuring a common methodology and inputs for the preparation of individual grid models to be merged into the common pan-European grid model.

In the near future, NCC is planning to approve the Congestion Income Distribution Methodology, which is currently being considered by all national regulatory authorities.
