The global market for uninterruptible power supplies (UPS) in the data centre segment reached around 4.91 billion US dollars in 2023. It is already estimated to reach 9.82 billion by 2031. This corresponds to an average annual growth rate (CAGR) of 9.1 percent. The main driver of growth is the increased use of cloud computing. Germany is also showing an unbroken growth trend.
Uninterruptible power supply ensures the supply of critical systems in the event of failures or voltage fluctuations. It switches on automatically, provides reliable power and enables the orderly shutdown of devices or the takeover by emergency power generators. Such systems regulate the voltage and protect electronic and mechanical components from damage caused by power surges. In Germany, the integration of UPS in data centres and companies is becoming increasingly important, especially in the context of the growing use of renewable energy sources such as wind and solar. Modern UPS solutions must work seamlessly with these sustainable power sources and stabilise energy quality to prevent data loss. They thus contribute significantly to the operational safety, efficiency and reliability of IT and cloud infrastructures.
The number of servers installed in data centres (DCs) is rising steadily worldwide and is expected to reach the 100 million mark for the first time in 2025. Demand is growing particularly strongly in the USA and China, but the number of servers in Germany is also increasing slightly – from 2.1 million in 2015 to 2.4 million in 2024.
This gives Germany the largest data centre capacity in Europe – a result of its strong economy and the steadily increasing demand for digital infrastructure. In addition to high on-premise capacities, Germany is also on a par with the United Kingdom in the areas of colocation and hyperscale data centres. According to the Borderstep research institute, the Frankfurt/Rhine-Main region in particular has gained significantly in importance in recent years and has partially overtaken the Greater London area, not least in the wake of Brexit. According to a survey of data centre experts, the Berlin-Brandenburg and Cologne-Düsseldorf regions are also becoming increasingly important as data centre locations.
Expectations until 2030: steady investment expansion
A Borderstep survey conducted in Germany in 2024 revealed that a majority of data centre operators expect to significantly expand their capacities by 2030. With increasing server numbers, more IT space and, as a result, higher power consumption, power density is also expected to rise: While classic applications are expected to require between 2 and 10 kW per rack in 2030, cloud workloads are expected to require 20 to 50 kW. AI applications could even reach over 100 kW per rack. According to forecasts, the maximum power consumption (IT connection power) of data centres will also increase by 2030 – to 4,850 MW. This is more than double the figure for 2022.
In 2024, around 2.9 billion euros was invested in the expansion of data centre infrastructures in Germany, i.e. in buildings and building technology. Of this, around 2.2 billion euros went into air conditioning equipment and systems, power supply and other building technology. A further increase in investment is expected in the coming years. In 2021, around 60 percent of the data centres surveyed in Germany stated that they were planning expansion investments within the next few years. In 2024, the figure was already 71 percent.
