We had set ourselves the following goal for the end of 2021: for the Group as a whole to meet all of its electricity requirements, and more than 90 percent of its total energy requirements, with renewable energy sources. And we have achieved this goal. 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), as is the case in the United States. As of the end of 2022, 27.7 percent of the power used throughout the Group was obtained via PPAs. 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. In 2022, we further expanded our own generation and commissioned 20 photovoltaic systems, with more already in planning.
As of the end of 2022, we operated over 330 photovoltaic systems, for our own electricity requirements, with a total generating capacity of about 6 200 kilowatts peak (kWp). In 2022, we further expanded our own generation and commissioned 20 photovoltaic plants. In 2023, we plan to commission around 120 more plants.
We use the Renewable Energies ESG KPI 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 (only available in German) 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.
