Automatically translated with deepl.com.

Regulation 2017/1485 establishing a guideline for transmission system operation of 14 September 2017 lays down harmonized rules for grid operation for transmission system operators (TSOs), distribution system operators (DSOs) and significant grid users (SGUs). This creates a common, clear legal framework for grid operation in order to facilitate EU-wide electricity trading and ensure system security. The SO Guideline also ensures that the necessary data and information are available and that their exchange between the partners involved is guaranteed. At the same time, it supports the integration of renewable energy sources, enables more efficient use of the grid and promotes competition in the interests of consumers.

The regulation contains numerous obligations for the transmission system operators regarding the design of various methods and processes. These methods and processes in turn contain concrete implementation proposals at national level for numerous areas regulated in the regulation, including

• the methodology for creating common grid models;
• the most important organizational requirements, tasks and responsibilities for data exchange for operational security or
• the FCR cost-benefit analysis with regard to the maximum activation time of the primary reserve that can be activated within seconds (FCR) in an endangered state.
