The advancing integration of renewable energies and the increasing interconnection of players in the energy network requires an Europe-wide model for standardized data exchange. In addition, various requirements on the local level all the way to the European level must be coordinated.
For this purpose, the "Generation and Load Data Provision Methodology" (GLDPM) defines the framework for capacity planning for transmission of electricity which already became effective in January 2018.
The participating network operators - transmission system operators (TSO), distribution system operators (DSO), and generation operators - are now required to supply operational data and information from their networks and connected stations. This includes generation schedules of generating plants or load forecasts.
The objective is a Europe-wide model (CGMM) which avoids power outages, ensures cost efficiency, and optimizes the use of resources and energy networks.
The energy transition results in higher utilization of the distribution networks. Continuous supply of energy is not possible with decentralized weather-dependent generation. Equal demand for the generated energy at all times of the day remains unlikely today as well as in the future.
Capacity calculation based on a standardized procedure for the electricity traded on the day-ahead and intra-day markets requires data exchange across networks. Under today's aspects, a transparent Europe-wide overview is absolutely necessary.
Using the data acquired in the GLDPM framework also increases the supply security of the own electricity network.
For the realization of the associated requirements, it is necessary to expand existing control systems and to add new components. For this purpose, PSI has developed modular, expandable, and therefore future-proof solutions as part of PSI SASO DSO 2.0 for distribution network operators.

The Generation and Load Data Provision Methodology (GLDPM) is the "provision methodology for the uniform collection of generation and load data".
Based on this methodology, the collected data are developed into a common network model (CGMM) of the European transmission system operators (TSOs) in order to comply with the EU regulation for "establishing a guideline for capacity allocation and congestion management" (CACM).
The regulation specifies pan-European rules for electricity trading as well as calculation and allocation of cross-border electricity transmission capacities.
The Capacity Allocation and Congestion Management (CACM) regulation regulates how transmission capacities in the European networks are to be calculated. Within the framework of the regulation, TSOs collect generation and load data whose framework conditions are formulated in the GLDPM. The objective is a common network model (CGMM) that allows a transparent, pan-European overview of the capacities of the European electricity grid.
The Common Grid Model Methodology (CGMM) describes the common network model of the European TSOs. It is a central element for the implementation of the European requirements for capacity calculation in accordance with the CACM regulation.
