For a reliable electricity supply, extra high-voltage grids with a high degree of grid availability are very important. Without transmission grids, cross-regional power transmission would not be possible within the national and international interconnected system. A guaranteed high transmission capacity is indispensable in this regard.
This already begins with the grid expansion; in particular because of the growing importance of renewable energy, the electrical grids have to meet new requirements. This means that the extra high-voltage grid has to transport renewable energy to the consumption centres and balance the fluctuating generation while guaranteeing system stability at all times.
The TSO plans its expansion so that its transmission grid is large enough to handle future transmission tasks, enabling safe, consumer-friendly, efficient and environmentally friendly operation and low-cost use of the network with an adequate quality of supply.
Grid use planning ensures that system security is not jeopardised by planned outages for grid installations. It takes into account the components that are important for grid security for the 50Hertz transmission grid, neighbouring transmission grids and grids of grid connection customers.
Grid operation covers all technical and organisational activities that are needed to ensure grid use and grid provision and trigger measures as soon as possible to remedy disturbances of the security/reliability of supply. The maintenance and construction measures have to be carried out in such a way that the use of the transmission grid agreed with the customers of 50Hertz can take place with as few restrictions and interruptions of the grid provision as possible.
