A schedule (when used to refer to an exchange schedule between balance groups) specifies how much power is to be exchanged between balance groups or injected or withdrawn at feed-in or withdrawal points for every fifteen minutes within the respective period of transmission.

This refers to part of the planning process. As part of the scoping appointment, the relevant authorities give the agency responsible for a project and the authorities involved opportunity to hold a discussion about the object, scope and methods in the application documents to be prepared as well as any other questions important for the execution of a procedure.

The Site Development Plan is created by the Federal Maritime and Hydrographic Agency in coordination with the Federal Network Agency and in consultation with the Federal Agency for Nature Conversation and the coastal states. The plan defines the spatial planning requirements within the German exclusive economic zone for the North Sea and Baltic Sea with respect to the systematic grid connection of offshore wind farms as of the year 2026. It can contain spatial planning decisions with respect to the coastal waters.

The Spatial Offshore Grid Plan was most recently created in 2016/17 by the Federal Maritime and Hydrographic Agency (BSH) in coordination with the Federal network Agency and in consultation with the Federal Agency for Nature Conversation and the coastal states. The plan defines the spatial planning requirements within the German exclusive economic zone for the North Sea and Baltic Sea with respect to the systematic grid connection of offshore wind farms. It contains standardised technical requirements and planning principles for an enviromentally sound and geographically acceptable implementation. The Spatial Offshore Grid Plan has been replaced by the Site Development Plan.

All persons or groups which have a vested interest in the progress or results of a process or project.

Investments in grid connection systems that remain either completely or partially unused.

A system operator (operator of a transmission or distribution network) is responsible for the safe and reliable operation of the respective network in a defined area and also responsible for the connections to other networks. In addition to this, the operator of a transmission network also regulates transmission using the network, in due consideration of the exchange with other transmission networks. The operator looks after the provision of essential system services, thereby ensuring the reliability of supply.

In terms of electricity supply, system services refer to services that are absolutely necessary for the proper functioning of the system, services that the network operators carry out for the network customers in addition to the transmission and distribution of electrical energy, thereby determining the quality of the electricity supply.
