[NTC DE-CH]: Special regime for NTC determination

by Transnet BW GmbH

Dear Market Participants,

due to unavailabilities of conventional power plants in the TransnetBW control area it is possible that capacities from Germany to Switzerland will have to be reduced below the values calculated by the current NTC determination methodology.

TransnetBW will assess the grid situation daily and act on the NTCs from Germany to Switzerland accordingly. The NTC will be limited to a value between 700 MW and 2000 MW depending on the grid situation. This special regime is foreseen to be applied until business (energy delivery) day 7th of July. The NTCs from Switzerland to Germany will not be impacted.

 Best regards,

TransnetBW
