Power generation in Germany is changing rapidly in the course of the energy transition and a 65% share of renewable energies is expected in 2030. To meet the challenge of integrating these quantities of renewables, it is necessary for the four German transmission system operators (TSOs) to supplement the mandatory grid expansion with technical innovations. The higher utilisation of the existing transmission system plays a particularly important role in this respect, because if the generated electricity exceeds line capacities, the TSOs have to carry out costly redispatch measures.
TSCNET shareholder TenneT, the Dutch-German TSO, plans to implement grid boosters, an innovation also considered in the German “Network Development Plan 2030”. The general idea of grid boosters involves fast power sources in the form of large batteries. TenneT’s grid booster concept provides for a higher utilisation of the grid during smooth operation. If a transmission line within the monitoring range of the grid boosters exceeds a predefined limit value, the load of the respective circuit is restored to permanently permissible values within a short time by reactive use of the grid boosters.
TenneT is now conducting a market survey on the grid boosters. The purpose of this enquiry is to prepare for the award of contracts and to inform the market players. All interested parties are invited to participate in this process and to submit a written statement on the intended approach by 31 March 2020 via a platform set up by the TSO. The results of the process should help TenneT to carry out a competitive, transparent and non-discriminatory award procedure.
