Hradec substation

Hradec substation (Czech: rozvodna Hradec) is a collector substation connecting the 220 kV and 400 kV grid in the Czech Republic's electricity grid.

It is situated in Rokle near its local part Hradec in the Ústí nad Labem Region.

In Hradec the high voltage transmission lines from the surrounding lignite-fired power stations come together and the distribution of load takes place.

There are direct 400 kV interconnections from the substation to Tušimice and Prunéřov power stations.

The 400 kV line to Etzenricht is connected from the busbar to the termination portal on the area of the substation via an underground cable.
