The principles of grid planning
The "principles for the planning of the German transmission grid" are listed in the lead policy of the German transmission system operators (TSOs)
to establish future- and demand-oriented system concepts for secure and efficient system operation within the national and European legal framework and under the obligations of the European joint operation.
The current TSO planning principles concern the intrinsic upgrade and harmonisation required for the German energy transition and European developments (3rd EU single energy market package, ENTSO-E Network Code).
With the publication of the planning principles updated in March 2012, the TSOs transparently and comprehensively explain the technical and economic principles of the grid expansion plan as a combination of grid optimisation, grid reinforcement and grid expansion. With a transparent grid planning procedure, the TSOs aim for greater acceptance of the grid expansion, which is particularly necessary in view of the energy transition.
Changes in the regulatory framework, possibilities to introduce new transmission technologies as well as necessary content-related and editorial specifications and additions have led to the further development of the TSO planning principles, which were published in their current version in April 2015.
The planning principles were also reviewed and developed further in the following years by the TSOs. With a transparent grid planning procedure, the TSOs aim for greater acceptance of the grid expansion, which is particularly necessary in view of the energy transition.
