Take Back Control: OEM-Independent Wind Turbine Service
When you bought your wind turbine, you didn’t agree to be locked to one supplier for its entire operating life. Yet most owners are, tied to a single OEM for software, service, spare parts, and data, on the OEM’s terms and at the OEM’s prices.
Nordic Wind Technology exists to change that. Our OEM-independent wind turbine service replaces the proprietary controller software on your turbines with our own open platform, so you decide who services your fleet, where you buy parts, and what you do with your data. With 30+ years of controller expertise and 550+ installed solutions, we give the power back to the people who own the turbines.
What "OEM-independent" actually means
“OEM-independent” means your turbine’s operation no longer depends on the original manufacturer. You are free to:
- Choose your own service provider: Do O&M in-house or use any independent service provider (ISP) you like, not just the OEM.
- Access all your turbine data: Full, transparent access to events, alarms, warnings, and parameter settings, with nothing hidden behind an OEM licence.
- Source spare parts freely: Buy from the supplier that offers the best price and lead time, instead of a single-source OEM channel.
- Control your own costs: No more take-it-or-leave-it service contracts on ageing turbines.
Independence, engineered right into the product.
The hidden cost of OEM lock-in
As turbines move past their warranty period, OEM support often becomes the single biggest constraint on profitability. Owners face rising service contract prices, slow spare-parts availability for older platforms, restricted access to their own operational data, and, in some cases, turbines that can’t be fully optimised because the software is a black box.
For a turbine that may run for another 10–15 years, that lock-in compounds. OEM-independence removes the constraint at its root: the controller.

What you gain
- Wind Turbine Software: Depending on turbine model and site, owners typically see a 1.4%–5% increase in Annual Energy Production (up to 7% observed on some Suzlon turbines).
- Freedom of service: Run maintenance yourself or through any ISP.
- Full data ownership: Complete, transparent access to your turbine’s operational data.
- Spare-parts flexibility: Source competitively instead of single-sourcing from the OEM.
- Grid compliance: Reactive power management and Power Park Controller integration where required.
- Extended, profitable lifetime: Keep ageing assets earning well past end-of-warranty.

GENERAL ELECTRIC
GE 1.5
General Electric began manufacturing their GE1.5 wind turbines in 1996 – the first 1.5MW was installed in Germany. The GE1.5 is especially well-suited for locations with height restrictions and high wind speed regimes. It features a DFIG generator with a frequency converter and a DC pitch system.
GE 2.5
General Electric began manufacturing their GE2.5 wind turbines in 2003 – the first 2.5MW was installed in Sweden. The GE2.5 is especially well-suited for locations with hight restrictions and high wind speed regimes. It features a DFIG generator with frequency converter and a DC pitch system.
SUZLON
Suzlon S62
The first turbines in the S6X series from Suzlon were manufactured in 2002 and eventually phased out in 2016. Today, 3673.75 MW of total capacity of S62 and similar turbines (S64 and S70) are installed around the globe.
Suzlon S64
Suzlon began manufacturing their S6X series wind turbines in 2002 and eventually phased out production in 2016. A cumulative capacity of 3673.75 MW is installed worldwide counting S64 and similar turbines like the S62 and S70.
Suzlon S66
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 S70
Manufacturing of the S6X series wind turbines began in 2002 and Suzlon eventually phased out production in 2016. Around 3673.75 MW of total capacity is installed around the globe (counting S70, S64 and similar turbines).
Suzlon S82
Suzlon inducted the S82 turbine in 2006 and phased out production in 2015. During these years a combined capacity of around 3034.5 MW was installed worldwide.
Suzlon S88
The first turbines in the S8X series from Suzlon were manufactured in 2004 and eventually phased out in 2015. A total capacity of 5712 MW was installed worldwide during this time period.
Suzlon S95
The Indian wind turbine manufacturer Suzlon launched their S9X series turbines, including the S95, in 2011. Due to its asynchronous double-feed generator with high slip (Suzlon Flexi Slip SFS) and Pitch system the S95 turbine is especially efficient and well suited for medium wind regimes and able to achieve an optimum energy yield with comparably low loads.
Suzlon S97
Suzlon launched its S9X series turbines in 2011 and phased out production of the S97 turbines in 2018. Today more than 2800 MW of total capacity is installed worldwide. regimes and able to achieve an optimum energy yield with comparably low loads.
Suzlon S111
The first S111 wind turbines from Suzlon were manufactured and grid connected in 2015. A total of 1354 MW capacity is installed worldwide.
