Experience & Trust
Your trusted partner for industrial power supply
For over 20 years, we have been constructing substations and grid connections for energy suppliers, grid operators and industrial companies throughout Germany. Over 250 substations that have been commissioned are testament to our expertise – and to the trust placed in us by clients from a wide range of sectors. As a medium-sized company headquartered in Riesa with a branch in Dresden, we combine the reliability of an established market player with short decision-making processes and personalised support. For you, this means having a single point of contact throughout the entire project – from the initial concept right through to the fully operational facility.
Everything from a single source
Turnkey substations – from feasibility study to commissioning
We manage the entire process of constructing your substation – from the feasibility study through to the preparation and submission of planning application documents, construction, primary and secondary design, the procurement and installation of all components, right through to programming and commissioning. This end-to-end responsibility, managed by a single provider, reduces the number of interfaces, minimises project risks and ensures that your facility is connected to the grid on schedule and within the agreed budget. This commitment to meeting deadlines is a decisive advantage, particularly for industry and large-scale consumers, for whom every hour of downtime is costly.
In-house production
Control cabinet construction and assembly carried out in-house
A key component of our value creation is our in-house manufacturing: we design and build the switchgear, protection, control and telecontrol cabinets for our projects ourselves – and as a result, we are recognised by all German network operators. This high level of in-house production gives you the assurance of consistently high quality, short response times and precise tailoring to your individual requirements. On request, we also undertake design and manufacturing contracts for switch cabinets for third-party customers – exactly in line with your technical specifications.
Installation & Cable Laying
Power plant construction and grid connection up to 380 kV
This is how we ensure a reliable connection between your site and the public grid – regardless of whether you are purchasing electricity or feeding self-generated energy into the grid.
Flexibility & Grid Stability
Battery energy storage systems (BESS) for greater security of supply
As the energy transition progresses, the need for flexibility and grid stability is growing. We develop, plan and build battery energy storage systems (BESS) with a capacity of 5 MW or more, including the grid connection point – with a focus on storage solutions ranging from 20 MW/2h to 100 MW/2h. Battery storage opens up concrete opportunities for industry and large-scale consumers: the integration of renewable energy, the optimisation of peak loads, participation in energy trading and the provision of balancing energy. In this way, you not only make your energy supply more secure and cost-effective, but also make a measurable contribution to the decarbonisation of your processes and to your climate targets.
Expertise for industry
Cross-sector experience for demanding requirements
Whether it’s the manufacturing sector, the chemical and process industries, the automotive and supplier sectors, logistics centres or energy-intensive facilities – we understand the specific requirements of different industrial sectors and apply our expertise across all sectors. As a national or international industrial company, you benefit from a partner who has the technical expertise to manage complex grid connection projects and guide you safely through all regulatory approval processes. As one of the market leaders in the renewable energy sector, environmental protection is always our top priority.
