As the world’s climate gets warmer, extreme weather events are becoming increasingly frequent. In the two decades to 2019, the number of major floods around the world more than doubled and severe storms rose by 40 per cent.1

For the telecommunications sector, these events can have severe impacts on the critical infrastructure relied upon by communities and the economy for fast and reliable connectivity. Broken facility pipes or flooded equipment can cause sites to short-circuit and result in significant downtime.

With extreme weather events expected to become more frequent in Denmark,2 TDC NET, the country’s largest digital infrastructure provider3 and a Macquarie Asset Management (MAM) portfolio company, is investing to mitigate the considerable impact these events can have on its data centres, network equipment and other critical infrastructure.


MAM, alongside its co-shareholders, is supporting TDC NET to build greater resilience in its digital network through a DKK10.5 million flood prevention and mitigation investment program focused on its 10 most critical facilities.4

This program has seen TDC NET install water sensors, alarms and watertight doors to minimise short circuits caused by flooding. The company has increased the frequency of maintenance on its pump and drainage systems and installed emergency power supplies to support continuity of service. The terrain surrounding its sites has also been landscaped to reduce the risk of flooding, with the works reviewed by an external specialised engineering firm to identify further opportunities for improvement.

In addition, TDC NET’s mobile network now operates across three physical locations to mitigate the impact of short circuits caused by the flooding of mobile equipment. In the event of one location flooding, failover data centres ensure continuity of service.


These investments are expected to help prevent floodwater damage to TDC NET’s critical assets and reduce remediation costs caused by flood damage.

Importantly, these measures can help to reduce critical infrastructure downtime, ensuring TDC NET can continue to provide its consumers with fast and reliable connectivity, enabling the telecommunications provider to maintain its position as one of Denmark’s leading mobile networks.
