The four German transmission system operators (TSOs), the TSCNET shareholders 50Hertz, Amprion, TransnetBW and Tennet, the Dutch-German TSO, ensure the supply of electricity under all circumstances and thus hold reserve capacities as ultima ratio for unforeseeable and exceptional extreme situations on the electricity market. The reserve capacity is calculated at 2GW and the facilities to provide the capacity are determined every two years by the TSOs through a tendering procedure.
Last week, the Bundesnetzagentur (German Federal Network Agency) approved the new standard conditions for the reserve capacity which had been drafted by the TSOs. The standard conditions are the basis of the contractual relationship between the respective TSO and the operator providing the capacity. They are designed to be as transparent as possible and include, among other things, rules on the availability and use of the reserve system, remuneration or contractual penalties.
Due to the standard conditions, the potential participants in the tender procedure know the terms under which the reserve facilities must be operated and the legal consequences in case of failure of a plant. Now that the conditions have been approved, the tender for the first performance period can start as planned on 1 September 2019.
