EXPERTREMANUFACTURED WIND TURBINE 

Repowering Solutions is a division of Jeraneas Group ofcompanies.

Our core business is the remanufacturing of wind turbines ofdifferent sizes; a work that we have been doing with goodsuccess for the past years. We have several references in Europeand Latin America. As an example, we have been the firstinstallation approved by Enel in Italy, using remanufacturedturbines (a Nordtank 300 derated to 200kw). Our final producthas the same lifespan than a new turbine, comes with 5 years ofguarantee.

We currently have different solutions for different projectsspecially in the range where you work: 60 to 2000kw. As amatter of fact, we sold 10 units of remanufactured turbine lastyear for the Italian, Spain, Nicaragua and UK market

We can adapt our scope to the different projects, from being asimple supplier of turbines, to a full EPC contractor. Thisflexibility will be very positive when collaborating with yourcompany, since we can create good synergies.

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 OEMmanufacturer specifications are repaired or replaced.

All bearings (roller or plain) are repaired or replaced withnew.

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.

Pinion gear is repaired or replaced with new having a widerface 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 orreplaced.

All electrical wiring and components are new and upgradedabove 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. ABB full power converter

STANDARD REMANUFACTURING PROCESS

ADVANTAGES REMANUFACTURED WIND TURBINES

Cheaper to transport, quicker to install

The light weight of the refurbished Wind Turbines minimizesconstruction and transportation costs.The refurbished Wind Turbines features a compact style of bladetransportation which allows the safe transportation of three bladesat one time using existing trucks and cranes. This makes installationquicker and minimizes transportation costs

Lowering maintenance costs for greater profitability

Maintenance and repairs can now be performed faster and cheaperup‐tower, and with greater technical ease, thanks to our updatedergonomic nacelle design with increased access and workingenvironment.With a ABB full scale converter, the complies with even the mostchallenging grid requirements of the modern energy market.

Grid requeriments

The refurbished Wind Turbines are designed for optimumcompliance with grid standards worldwide. The Full Power Converterof ABB advanced grid compliance system provides active andreactive power regulation, fast response to changes in frequency andfault ride‐through capabilities to support grid levels and stability inthe event of grid fluctuations.Investing in a refurbished Wind Turbines means investing in turbinesthat can adapt to even the most challenging grid codes.

Low Balance of Plant (BOP)

Installation and transportation costs refurbished Wind Turbines justlike is designed to be transported easily (by rail, truck or ship) tovirtually any site around the world. In termsof weight, height and width, all of its components comply with localand 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 WindTurbines due to its improved load control. The innovative powersystem provides excellent grid support and is highly adaptable forfuture technical requirements.It also enables substations to be simpler and therefore more cost‐effective.
