4 FAQs about Emergency use of 20kW German data center racks

What are the new energy rules for data centers?

The Act provides for new rules on energy efficiency, energy reuse, waste heat, power supply from renewable energies and energy management systems, which are intended to make the operation of data centers more sustainable and the industry more innovative. These rules will come into force over the coming months and years.

Will new data centres become more energy efficient in Germany?

In the Energy Efficiency Act, Germany has set a PUE value of 1.2 percent as the threshold for new data centres coming online from July 2026 onwards, which will lead to a sig-nificant decline in average PUE values. But this only applies if it is assumed that new data centres continue to come online with high processing capacities.

How much electricity do data centres need in Germany?

Strong growth in data centre capacities can be expected in Germany, as can an ongoing rise in electricity needs. In 2024, data centres and smaller IT installations in Germany required 20 TWh of electricity, a figure which comprised around 4% of Germany's gross electricity consumption of 517 TWh (2023).

What is a data center energy reuse factor (ERF)?

In concrete terms, this means that data centers with an output of 1 MW or more that go into operation on or after July 1, 2026, must have an energy reuse factor (ERF) of at least 10 percent. This value will successively increase to 15 percent if operations start from July 1, 2027, and 20 percent if they start from July 1, 2028.
