Following its launch in June 2018, the Baden-Württemberg grid security initiative “DA/RE” (“DAta exchange/REdispatch”) has entered the pilot phase on 1 April. The DA/RE initiators are TSCNET shareholder TransnetBW, the German transmission system operator (TSO) from the state of Baden-Württemberg, and the southwest German distribution system operator (DSO) Netze BW with the support of the State Ministry of the Environment, Climate Protection and the Energy Sector. Meanwhile, several grid and facility operators are involved and actively participating in the pilot phase.
DA/RE responds to the increasing volatility and decentralisation of power generation. By utilising the flexibility potential of decentralised plants from lower grid levels, the entire electricity system is intended to be stabilised. Basically, DA/RE is an IT platform, through which grid operators can obtain information on flexibility potentials and coordinatedly retrieve them. In the trial phase, scheduled to last until the end of September 2019, two essential modules for data exchange and coordination between grid and facility operators are to be tested.
With its wide range of decentralised systems, DA/RE adequately represents the current market for flexibility. “Together we can thus test the processes with different DSOs up to medium voltage level and provide the further course of the project with valuable experience,” explains Florian Gutekunst, DA/RE project manager at TransnetBW.
