Our service offers are based on almost thirty years of experience in the industry and include all preparatory, technical and commercial aspects of the planning, construction and operation of wind energy plants up until the Repowering process.

Project Development

The purpose of project development is to determine possible locations for the construction and operation of wind energy plants.

It entails the following steps:

  • Carrying out restriction analysis / identifying areas with wind potential
  • Creating a specific wind farm concept (locations, turbine type/height)
  • Securing the location
  • Overseeing survey management (wind, shadows, noise, avifauna, bats, etc.)
  • Performing approval procedures in line with emission control laws
  • Supervising municipal zoning
  • Planning and securing the grid connection (incl. substation where necessary)
  • Excavation planning (soil analysis, path and cable route planning)
  • Drafting compensatory measures in line with nature protection laws
  • Repowering

All services will be carried out in accordance with current laws and regulations. We will look to every step in the process conscientiously and thus create a solid base for a successful project progression.

Commercial Project Management

Thanks to our expertise, we are able to provide alternative operating plans ourselves. In special cases, we can count on our long-term external advisors in order to resolve even challenging constellations without delay.

Our commercial project management covers the following services:

  • Performing profitability calculations
  • Structuring the company in line with legal requirements
  • Drafting and checking all the documents and reports necessary for securing funding
  • Financing projects (conditions of disbursement)
  • Overseeing any other contractual relationships (e.g. insurance) and the necessary easement applications (e.g. in relation to the location, access routes, cables, clearance, rotor or compensatory measures in line with nature protection laws)
  • Raising capital (project sales, selling individual shares)
  • Community participation concepts

Grid connection

WindStrom services for a successful grid access:

  • Application for and commissioning of grid connections
  • Construction and initial operation of transmission or transformer stations
  • Cable dimensioning, selection and route planning
  • Commissioning of power quality inspection
  • IT-based simulation of the electrical specifications
  • Technical documentation
  • Submission of the necessary certificates and reports to the distribution grid operator in accordance with the deadlines
  • Supervising the initial feed-in process


Sound project management is just as essential to us during the implementation. We will take responsibility for purchasing the wind energy plant and overseeing all the measures associated with its construction, including producing the draft design, appointing and coordinating the various trades (preferably using local businesses), supervising construction and organising the construction site up until the commissioning of the plant on the agreed date. This also includes overseeing the inspection and approval process as well as the certification of the wind farm.

Find our implementation services in detail below:

  • Purchasing the wind energy plant independent of the manufacturer
  • Producing the draft design
  • Appointing and inviting tenders from all trades (e.g. for road construction, grid connection and foundations)
  • Supervising construction
  • Ensuring the plant is commissioned on the agreed date
  • Taking care of certification of the plant (e.g. SDL)
  • Overseeing the inspection and approval process for the wind farm
