NSA test

The WTC emergency power system will be tested on Sunday 15 March 2020 between 7:00 AM and 1:00 PM. During this test the power supply to towers A, B, C, F, G, H and I will be switched on and off several times. For security reasons, the WTC complex (with the exception of tower E) will be completely closed on this day between 7:00 AM and 1:00 PM.

We advise you to remove your own installation from the power grid, because the disconnection and connection can be accompanied by short peak voltages.

The next NSA test will take place on 20 September 2020.
