TURBINE RETROFIT
SUZLON S66
WHY RETROFIT YOUR SUZLON S66?
First of all, retrofitting your S66 turbine will make you 100% percent independent from Suzlon – something many turbine owners/operators dream of. By updating your turbine, you gain full access to the turbine data and parameter settings and the freedom to choose your service provider. Other benefits include:
- Upgraded data access and improved service tools to lower O&M costs
- Access to spare part supply chain, spare parts available directly from the manufacturers
- Pitch module (MOOG)
- Soft starter (IXYS)
- Grid module (WOODWARD)
- Suzlon Flexi Slip module (Bachmann)
- Optimized availability and energy production with control of mechanical loads
- Flexibility to add own extensions, including sensors or CMS system
- Enhanced remote turbine monitoring and control
- Power curtailment and reactive power control, enabling previously unattainable incentives by complying with modern grid codes
- Fast installation time, only 1-2 hours downtime for installation
Please do not hesitate to contact us if you require further information about our retrofit solutions for Suzlon S66 turbines.
This is what OEM-independent wind turbine service looks like: your data, your parts, your choice of engineer.
GENERAL INFORMATION
TURBINE MODEL
Suzlon S66
YEAR OF MANUFACTURE
2002 – 2016
FURTHER INFORMATION
The S66 is part of Suzlon’s classic fleet of wind turbines. Production began in 2002, and the S66 was eventually phased out in 2016. During that period, a total of 3673.75 MW capacity was installed globally (counting S66, S64, and similar turbines).
Suzlon designed the S66 with a dual-rating asynchronous generator and a pitch system that makes the turbine capable of delivering an optimum energy yield within a wide wind range with proportionally low loads.
Nordic Wind Technology offers two certified retrofit solutions for Suzlon S66 turbines: an MITA solution and a Bachmann solution.

BACHMANN SOLUTION
Older Suzlon S66 turbines were installed with MITA WP3000 hardware and LUST LTi DriveStat (UDS 035 Analog). For these models, we offer a retrofit solution consisting of a software update and a new MITA controller, WP4000.
Newer S66 turbines contain Bachmann hardware and LUST LTi DriveStat (UDS 035 CAN) or LUST LTi PITCHmaster (CDE 54.XXX). Our Bachmann solution is a software-only solution. We replace the Compact Flash card in the Bachmann Controller with a new one without interfering with the existing hardware.
