Green electricity and energy efficiency
Future-proof IT starts with sustainable energy
For us, the use of green electricity is a central component of a responsible and future-proof IT infrastructure. It supports the transition from conventional energy to clean, resource-saving power generation and at the same time contributes to greater independence and long-term planning in the operation of our infrastructure – also in the context of digital sovereignty. Complemented by energy-efficient technology, transparent processes and numerous certifications and awards, we are laying the foundation for sustainable, stable and trustworthy hosting services.
Use of green electricity and focus on energy efficiency
We rely on green electricity for the operation of our infrastructure and aim to make the energy use of our data centers as sustainable as possible. At netcup, we use electricity from hydropower and at the same time place a strong focus on energy-efficient hardware and optimized operating processes.
We specifically use modern server components with integrated energy-saving functions in order to achieve the lowest possible power consumption with the same performance. The reduced energy requirement not only improves the environmental footprint of our infrastructure, but is also economically relevant, as electricity costs represent a significant component of the operating costs of hosting infrastructure.
Hydropower as an energy strategy
One particularly tangible component of the sustainable energy supply comes from the parent company Anexia. In 2024, it took over its own run-of-river power plant in Kammern, Styria, Austria. This hydroelectric power plant generates around 600 kW of electricity and is used to cover part of the electricity requirements of the data center and cloud infrastructure, particularly at the Vienna site, from its own renewable generation. This corresponds to around a third of the Vienna data center's electricity consumption.
The investment was deliberately made as a long-term infrastructure measure. When operating the power plant, attention was paid to accompanying ecological measures such as fish ladders in order to minimize the impact on the local ecosystem
Additional power from solar energy
In addition to hydropower, we are investing in the generation of solar power. A photovoltaic park was built in Jaidhof (Lower Austria), which comprises 1,428 solar modules on an area of around 1.16 hectares. The plant has an output of almost 1 MW and generates around 1,127 MWh of electricity per year.
This solar power is used to operate the data center infrastructure. The aim of the project is to reduce dependence on external electricity markets and ensure a more stable energy supply in the long term. In addition, measures were implemented to promote biodiversity, including the planting of native plant species.
Technical measures to reduce energy consumption
In addition to power generation, the reduction of absolute energy consumptionplays a central role at netcup. We rely on modern, energy-saving server hardware, optimized cooling concepts and demand-based utilization of our systems. This approach follows the principle that sustainable IT is not only achieved through the choice of energy source, but also through the efficient use of existing resources.
The reduced power requirement has a positive effect on our cost structure and supports long-term stable pricing across our entire product portfolio - from server and hosting services to domain services.
