• GLDPM - Standardized data exchange for the future of the European energy supply

    Generation and Load Data Provision Methodology (GLDPM)

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.

GLDPM overview

  • Optimization of the energy networks and efficient use of resources
  • Stable electricity network and improved supply security
  • Integration of renewable energies
  • Harmonization of cross-border energy markets
  • Better cooperation between network operators

"When it comes to electricity, European countries are highly interdependent."

Laurent Schmitt, ENTSO-E’s Secretary General.

Expansion module GLDPM for network operators

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.

Since the beginning of 2018, the European transparency regulation requires all energy generators and plant operators to share their load and generation data with the upstream transmission network operators and to provide the corresponding equivalent network models.

What does this mean for you?

  • Generation schedules for conventional generation plants > 10MW and loads > 50MW must be provided to the adjacent transmission network operators.
  • Network data models must be provided for every hour of the day. They must be valid for the two following days.
  • The network models must include power flow scenarios which also consider the downstream networks.
  • The data acquisition must be documented to enable tracing. This includes all data sources, data paths, and data storage with appropriate information storage and retrieval.

GLDPM as an opportunity

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.
