Spare parts, components and services relating to ENERCON wind turbines – from the reconditioning and provision of spare parts to the replacement of large components.
As wind turbines age, the availability of spare parts, professional maintenance and cost-effective repair solutions are becoming increasingly important. Especially in the case of older ENERCON wind turbines, a specialized, independent service can help to reduce downtimes, ensure technical availability and enable continued economic operation for many years.
An essential component is the reliable supply of spare parts and components. Especially with older generations of systems, the short-term procurement of certain components can become increasingly challenging. In addition to new parts, professionally refurbished components therefore play an important role. Used assemblies and electronic components are professionally tested, repaired and prepared for reuse. The spectrum ranges from circuit boards and control components to pitch and blade control technology and more complex electrical assemblies. Such remanufactured components are available on the market for ENERCON turbines of the E-40 to E-82 series. Refurbishment can not only offer economic advantages over new procurement, but also help to ensure the availability of spare parts for older wind turbines in the long term. Comprehensible testing and processing processes as well as corresponding quality and ESD standards are important.
In addition to the supply of spare parts, the regular maintenance and servicing of ENERCON wind turbines is one of the central services of specialized service providers. For system types from the E-40 to the E-92, different support models are offered, which can range from classic maintenance according to manufacturer specifications to comprehensive full maintenance concepts. Depending on the operator's requirements, maintenance, inspections, fault clearance, wear parts and repairs can be ordered individually or bundled in longer-term service contracts. More extensive contract models may also include large components and technical availability guarantees. The aim is to make technical risks more calculable and to keep unplanned downtimes as low as possible.
If damage occurs to larger components, specialized teams and careful project planning are required. Typical services include the replacement of main bearings, yaw components, generators or rotor blades. In addition to the actual assembly work, the scope of services often includes the procurement of the required components, crane and transport logistics, special tools, dismantling and reassembly as well as the subsequent recommissioning. Especially in the case of older wind turbines, it should be checked how repair costs, expected remaining service life and future yields relate to each other before replacing major components.
In gearless wind turbines, the generator is of particular importance. Moisture, corrosion, soiling or damage to insulation and coating can lead to costly repairs as the system ages.
Through regular condition checks, cleaning, corrosion protection and maintenance of the generator, incipient damage can be detected at an early stage. If damage has already occurred, the repair options range from work on individual windings to the renewal of larger winding areas to the replacement of components or the complete generator, depending on the findings.
For operators of older ENERCON turbines, it is not only classic maintenance that is decisive. Spare parts supply, refurbishment, repair expertise and large component replacement are increasingly intertwined. An efficient service partner should therefore be able to react to faults at short notice as well as offer solutions for the medium and long-term supply of spare parts. Especially in the case of wind turbines that are to continue to be operated economically for several years, the combination of preventive maintenance and targeted reconditioning of existing components can make an important contribution to extending the technical service life.
