Balancing group
Base load

Base load is the part of a consumption device’s load or of the total network load that remains constant over a period of time (e.g. day, month, year).

Black start capability

Black start capability describes a block-unit power plant's ability to restart itself from a switched-off state, irrespective of the state of the electricity grid. If a large-scale collapse of the electricity grid should occur, these power plants represent the first step towards restoring the electricity supply. Every TSO must ensure that there is a sufficient number of generation units available in their control area that have a black start capability.

Block-unit power plant

A block-unit power plant is a generation unit, which has a direct circuitry link between the main facility components (e.g. between steam generators, turbines and generators in thermal power plants).

Border corridor

The border corridor encompasses the sections defined in the Site Development Plan along the borders between the exclusive economic zone and the German coastal waters (12 sea miles zone) through which cable routes run.

Bundling point

For planning purposes, grid connection systems, that have not yet been assigned to a cluster or region start at a grid connection point on land and end at the so-called bundling point offshore. The bundling point is used as an end point to determine the length of the grid connection system in the preliminary planning process.
