Our approach to more renewable energy

Our contribution to the SDGs

We had set ourselves the following goal for the end of 2021: for the Group as a whole to meet 100 percent of its electricity requirements with renewable energy sources. And we have achieved this goal. As a result, we now meet more than 90 percent of our total energy requirements with renewable energy sources. To underscore this commitment, we have joined the global RE100 initiative, which aims to advance the purchase of electricity from renewable sources.

In this context, we are sourcing more green electricity directly, acquiring corresponding guarantees of origin, or concluding special power purchase agreements (PPAs img). As of the end of 2023, 32.5 percent of the power used throughout the Group was obtained via PPAs. In Germany and Europe the figure was 30 percent. We aim to increase this figure to 50 percent by 2025 in Germany and Europe. Whenever possible and practicable, we invest in our own power plants, such as cogeneration plants or photovoltaic systems.

As of the end of 2023, we operated over 308 photovoltaic systems in Germany, for our own electricity requirements, with a total generating capacity of about 6.01 MWp (Megawatt-peak).  In 2023, we pressed ahead with the construction of further PV systems. In 2024, we plan to commission a three-digit number of PV systems.

We use the ESG KPI img “Renewable Energy” to measure our progress. In addition, we have also introduced parameters throughout the Group that are used to assess electricity procurement at all of our national companies in terms of sustainability.

Since 2019, we have been testing a climate-neutral power supply for cellular base stations in which we use fuel cells instead of diesel generators. Fuel cells are economical, silent, low-maintenance and, most importantly, thanks to the use of bio-methanol, carbon neutral.

ESG KPI “Renewable Energy” KPI

The ESG KPI img “Renewable Energy” is calculated as the share of renewable energy in the Group’s total electricity consumption. Since 2021, we have been sourcing 100 percent of the electricity we use, throughout the Group, from renewable energy sources. By reaching this milestone, we have achieved one of our climate targets.

We are working to reduce our energy consumption overall, by improving our energy efficiency and implementing energy-saving measures. Further information can be found here.

Although we meet our power requirements wherever possible via PPAs img, our own power generation, and direct purchases, capacity limitations require us to also depend on sources for which guarantees of origin (GOs) come into play. GOs are an important element in our efforts to meet 100 percent of our electricity requirements via renewable energy sources and thereby achieve our climate target in this area.

Renewable energy in the Group KPI

Group-wide, we cover 100 percent of our electricity consumption using renewable energies. To this end, all European national companies can also purchase renewable energy certificates (guarantees of origin) if needed. As of this year, the graphic also includes other renewable energies, such as renewable district cooling.

Germany segment: renewable energy

The Germany segment img aims to expand and operate its networks on a responsible, environmentally friendly and sustainable basis. To this end, like all other Group departments, it is meeting its energy needs entirely using renewable sources.

Purchasing electricity from renewable energy sources
Power purchase agreements (PPAs img) for green energy are a key instrument in Germany’s energy transition. Deutsche Telekom subsidiary Power & Air Solutions (PASM img), which supplies Telekom Deutschland with energy, is steadily increasing the proportion of energy it purchases under these PPAs. Some 495 GWh of energy were purchased via PPAs in 2023.

During the year under review, Vattenfall began work to construct Germany’s largest agrivoltaic installation in Mecklenburg–Western Pomerania. The energy supplier plans to establish a combination of solar panels and agricultural activity over an area of 93 hectares. Telekom Deutschland intends to purchase all of the solar energy produced there once it has been completed. The 79 MW installation has the potential to supply energy to some 2 500 cellular base stations.

The partnership between PASM and energy utility EnBW promises to deliver clean energy from the North Sea. Deutsche Telekom has signed a new PPA that will see it receive 400 GWh of wind energy per year in future from the “He Dreiht” (Dutch for “He turns”) wind park, one of EnBW’S largest offshore wind parks in Europe. Construction is due to begin in May 2024.

Energy from photovoltaic systems
Deutsche Telekom continued to fit photovoltaic systems to more of its roof surfaces and open spaces in 2023. The addition of new buildings in the year under review means that the Group’s photovoltaic capacity has increased in many locations. These properties will also be fitted with photovoltaic panels in coming years. For the sake of efficiency, PASM works with energy start-ups such as ENVIRIA and Emondo, among others.

Building our own power storage systems
Power storage plays a key role in the generation of green energy, which is weather-dependent. For this reason, PASM began to build large storage systems in 2022. These systems store surplus renewable energy for subsequent use as required. Construction work commenced on some of the storage solutions in 2022 and was continued at four Deutsche Telekom sites in Germany in the year under review. Once this work is complete, the company will have a total storage capacity of 300 MWh. With these efforts, Telekom Deutschland is leading the way in the telecommunications industry.

    Day after day, we work to develop climate-neutral business practices and establish circularity

    In ramping up our climate targets, we have fulfilled the stringent criteria of the Science Based Targets initiative and become the first DAX-40 company to have a recognized, science-based net-zero climate target.

    For the first time, we are outlining our route to net zero here in the form of a climate transition plan. We are already implementing the key measures set out in the plan. We achieved significant improvements in our KPI “Energy Intensity” by introducing efficiency measures in our networks and data centers.

    To reduce Scope 3 emissions, we set up a task force that works closely with suppliers to explore new approaches to recording CO₂ emissions. Other sustainability criteria are applied to procurement decisions to create an economic incentive. One of the main criteria is the requirement to observe the principle of circularity for network technology and devices from the design and procurement stage onwards. When it comes to devices in particular, circularity can only be achieved in cooperation with customers. We addressed these stakeholders directly in 2023 by means of programs to purchase used devices, special initiatives, and our infotainment magazine “Heute retten wir die Welt! Ein bisschen.” (English: “Today we save the world! A little bit.”) on MagentaTV.

    We support our customers in their efforts to adopt a more climate-friendly lifestyle. Our products and solutions generated positive CO₂ effects for our customers amounting to 16.9 million metric tons in Germany alone in 2023.

    Further examples of our progress in 2023, from the perspective of the Group and that of our segments, can be found in the subchapters.
