EXPERT REMANUFACTURED WIND TURBINE

Repowering Solutions is a division of Jeraneas Group of companies. Our core business is the remanufacturing of wind turbines of different sizes; a work that we have been doing with good success for the past years. We have several references in Europe and Latin America. As an example, we have been the first installation approved by Enel in Italy, using remanufactured turbines (a Nordtank 300 derated to 200kw). Our final product has the same lifespan than a new turbine, comes with 5 years of guarantee. We currently have different solutions for different projects specially in the range where you work: 60 to 2000kw. As a matter of fact, we sold 10 units of remanufactured turbine last year for the Italian, Spain, Nicaragua and UK market We can adapt our scope to the different projects, from being a simple supplier of turbines, to a full EPC contractor. This flexibility will be very positive when collaborating with your company, since we can create good synergies..

STANDARD REMANUFACTURING PROCESS All components are removed for cleaning and inspection. Any component not meeting OEM manufacturer specifications is repaired or replaced. The nacelle frame is inspected for cracks and overall structural integrity. Any deficiencies are repaired and tested. The machine base and frame are stripped of all paint, cleaned of dirt and lubricant, and repainted. All critical rotating components (cylinders, rollers, etc.) are inspected for run out. Any component not meeting OEM manufacturer specifications are repaired or replaced. All bearings (roller or plain) are repaired or replaced with new. All belting is repaired or replaced with new. All rubber hydraulic lines are repaired or replaced with new. All polymer couplings are repaired or replaced with new. All hardware is repaired or replaced with new. All gear boxes are cleaned, inspected, and new seals installed. Gears are inspected and repaired or replaced if needed. All generators are cleaned, inspected, and 100% rewound. Brake calipers are rebuilt, including new brake rotor and brake pads. Bull (Yaw) gear is repaired or replaced with new having a wider face than the OEM gearing. Piniongearisrepairedorreplacedwithnewhavingawider face than the OEM gearing. All Oil on wear blocks are replaced with new. All blades are inspected for defects, including wear, cracks, and blemishes. All blades are protected with a new covering of gel coat. All blades are weighed, balanced, and matched. Blade over speed mechanisms are inspected. Any component not meeting OEM manufacturer specifications are repaired or replaced. All electrical wiring and components are new and upgraded above and beyond original manufacture specification. The main control system is repaired or replaced for new. Wind vane and anemometer are repaired or replaced with new.

ADVANTAGES REMANUFACTURED WIND TURBINES Cheaper to transport, quicker to install The light weight of the refurbished Wind Turbines minimizes construction and transportation costs. The refurbished Wind Turbines features a compact style of blade transportation which allows the safe transportation of three blades at one time using existing trucks and cranes. This makes installation quicker and minimizes transportation costs Lowering maintenance costs for greater profitability Maintenance and repairs can now be performed faster and cheaper up tower, and with greater technical ease, thanks to our updated ergonomic nacelle design with increased access and working environment. With a ABB full scale converter, the complies with even the most challenging grid requirements of the modern energy market. Low Balance of Plant (BOP) Installation and transportation costs refurbished Wind Turbines just like is designed to be transported easily (by rail, truck or ship) to virtually any site around the world. In terms of weight, height and width, all of its components comply with local and international limits for standard transportation. Specifically, not one of its components weighs more than 30 tones. Your foundation costs are also lowered with the refurbished Wind Turbines due to its improved load control. The innovative power system provides excellent grid support and is highly adaptable for future technical requirements. It also enables substations to be simpler and therefore more costeffective. Grid requeriments The refurbished Wind Turbines are designed for optimum compliance with grid standards worldwide. The Full Power Converter of ABB advanced grid compliance system provides active and reactive power regulation, fast response to changes in frequency and fault ride through capabilities to support grid levels and stability in the event of grid fluctuations. Investing in a refurbished Wind Turbines means investing in turbines that can adapt to even the most challenging grid codes.
