Your space, our technology
From land to development-ready site
You secure sites and develop them – we take care of the technical side. Based on your land parcels, we assess the site, the grid connection point and grid compatibility, evaluate the technical design and provide you with reliable information on timelines and costs. This transforms a plot of land into a project that can be brought to the stage where construction can begin.
Your benefit
Why project developers choose WT Energiesysteme
Whether it’s a wind farm, solar farm, electrolysis plant or large-scale battery storage facility: grid connection is the critical milestone of your project. Delays at the substation jeopardise funding deadlines, feed-in guarantees and your entire profitability analysis. As a specialist substation contractor, we take full responsibility for this – so that you can concentrate on developing your project. We think in terms of project life cycles, not individual trades, and support you from the initial feasibility study right through to stable grid operation.
Full service
Everything under one roof – from the greenfield site to the handover of the keys
You receive the full range of services for your substation from a single source: feasibility study, preparation and submission of planning application documents, structural, primary and secondary design, procurement and installation of all components, programming and commissioning. Instead of having to coordinate multiple trades, you have just one point of contact – with clearly defined responsibilities, short decision-making processes and a binding schedule. This reduces interface risks and significantly speeds up your project.
Our sectors
Experience across every sector of the energy transition
As one of the leading providers in the renewable energy sector, we understand the specific requirements of your industry – and those of the relevant grid operators.
Our process
From the feasibility study to grid operation: our process
Five phases, one point of contact – this is how we manage your substation, from the initial assessment right through to ongoing operations.
01
Feasibility study
We assess the site, the grid connection point and the technical framework.
02
Planning application and design
We draw up and submit the planning application documents and take care of the entire planning process.
03
Procurement and assembly
We supply and install all primary and secondary equipment.
04
In-house production
Switchgear, protection, control and telecontrol cabinets are manufactured in our in-house production facilities – and are approved by all German network operators.
05
Commissioning and After-sales Service
Once testing and programming are complete, we hand over a system that is ready for operation and support you with maintenance and modernisation.

Frequently asked questions from project developers
On request, we can manage the entire substation project from a single source – from the feasibility study through to the planning permission application, design and construction, right through to commissioning and after-sales support. You will have just one point of contact and a binding schedule, which significantly reduces interface risks and the effort required for coordination. Of course, we also carry out individual service packages – such as secondary equipment or control cabinet manufacturing – if you only require specific parts of the project.
