Performing technical due diligence assessments and supervision of the construction measures, Ramboll acted as owner’s engineer during the execution and construction phase.

The public utility of Munich in Germany, Stadtwerke München, has made another big step towards its objective to supply the entire City of Munich with green energy by 2025.
With the acquisition of the Sidensjö wind farm, one of Sweden’s largest onshore wind farms, Stadtwerke München will be able to meet the energy demand of approximately 125,000 households.

In order to secure a sustainable investment, potential risks inherent in the designs, selected components and contracts were identified. Beyond the pure consideration of specific technical issues, Ramboll’s approach was to ensure the client’s interest by subsequently negotiating and amending the transaction conditions and thus enabling it.

Working scope

In the course of the due diligence process on the existing energy yield assessments of the wind farm, all relevant project contracts, civil and electrical designs and the technical aspects of the permits were assessed. In order to reliably evaluate future energy yields, Ramboll prepared an additional fully bankable wind report. Furthermore the concepts for logistics, construction and operation as well as the project-related CAPEX and OPEX assumptions were reviewed.

The assessment of the project’s entire technical documentation provided the basis for the effective advice and support of the buyer during the acquisition process.
During the negotiations, Ramboll was able to achieve relevant improvements of key contracts (EPC, TSA, SAA, TCMA) and an adequate adjustment of the project price.

During the construction process Ramboll worked on ensuring compliance with deadlines, budgets and quality requirements. Furthermore, all executive designs were assessed in detail and a continuous on-site monitoring and control of all activities related to the structural realisation of the project was performed as well.
