DTU conducts public tender of contract for the supply of 2 UPS facilities.

The DTU has seen disruptions in the electricity supply network lately. These disruptions appear as short-term outflows of electricity supply and occur 1-4 times annually at regular intervals, but are accretive.

Economically, these disruptions have had a significant negative impact on DTU, e.g., DTU Nanolab. The outfalls of electricity supply have in the past caused ongoing research, trials, production and cost equipment to be destroyed.

Therefore, in order to ensure new research/trials as well as valuable equipment, DTU wants to establish UPS facilities as soon as possible. This will ensure that electricity supply is stable to such an extent that research, trials, production and equipment are protected and not significantly affected by power outages.
