Technical turbine reports for the authorisation of wind farms
Wind farm technical report: we prepare reports suitable for approval, tailored to the project and authority requirements, and advise on turbine selection.
Depending on the authority's requirements, technical turbine reports are required for the authorisation of your wind farm project. We take care of this. Even beforehand, we support you in selecting the optimal turbine type and equipment, from SCADA and ice detection to fire protection.
We then review the documents provided by the wind turbine manufacturer and prepare an approvable turbine report tailored precisely to the requirements of your project. We also assist in communication with the turbine manufacturer. The example of Upper Austria shows which details a project needs for the authorisation under electricity law: a technical description covering location, purpose, scope, mode of operation, design and electrical safety, plus site plans, sections, a statement of the expected immissions and the grid operator's statement. Outside the safety zones of aerodromes, structures 100 metres or more in height also count as an aviation obstacle and require an exemption permit under aviation law; within safety zones, this may also apply at lower heights. The shared prerequisites there are the state of the art, the avoidance of hazards, the limitation of nuisance from noise, shadow or vibration, and the safety of the electrical systems.
From a technical perspective, the aim is to demonstrate that the design and equipment of the turbine suit the site and the requirements of the procedure. Certification is important for the design: the current standards and certification rules apply to the conformity assessment and certification of wind turbines. Type certification covers the assessment of design, loads and safety as well as testing and supervision of manufacturing, while project certification additionally checks whether turbine type and foundation suit the site conditions. For safety-relevant systems such as ice detection, experts often check that a current type certificate is available. Warning signs and lights on access routes for the ice-fall season, which must be checked regularly, can also be required as a condition. The required evidence depends on the standards and rules applicable in the procedure and in the certification system. Site-specific suitability and project-specific aspects are assessed in the project and site assessments provided for that purpose.
The report also describes the turbine equipment, including the shutdown criteria, for example for ice accretion, very high wind speeds or shadow flicker. How an ice detection system operates, including shutdown, restart once the turbine is ice-free and behaviour in the event of a malfunction, depends on the system used, its parameterisation and the conditions imposed by the authorities. A shadow shutdown works with a light sensor on the nacelle. Rotor diameter and hub height also determine the range of the shadow flicker, which the shadow flicker assessment evaluates, and the visibility of the turbine, which the landscape and townscape assessment assesses. We plan which equipment a site needs in our advice on site-specific turbine equipment, turbine safety and occupational safety. The report is part of the specialist support for the authorisation procedure. After authorisation, we prepare the tender for the wind turbines.
