The global wind energy market witnessed huge growth from 2009 to 2010 as total wind power capacity grew by 22.3%. The global wind energy installed capacity increased at a Compound Annual Growth Rate(CAGR) of 27.9% from 74,107 megawatt (MW) in 2006 to 198,203 MW in 2010, of which 36,100 MW went online in 2010. Although the cumulative capacity for wind power grew, there was a 10.9% fall in annual additions in 2010 as major wind markets such as the US, Germany and Spain faced economic problems following the global economic crisis. The global wind power markets are expected to recover in 2011 due to the huge order intake by major wind manufacturers, the growing Asia-Pacific (APAC) region, emerging South America and Africa regions, steady European wind markets and recovery in North America. Wind power manufacturers across the world had a high order intake in 2010 with expected delivery deadlines in 2011 and 2012. This will contribute to the annual installations in 2011-2012.

According to GlobalData, wind farms installed up until 1996 were considered to be potential wind repowering sites in 2011. The global wind repowering market has increased significantly during the last five years, and cumulative installed capacity grew from an estimated 877 MW in 2005 to an estimated 2,499.4 MW in 2011 with a Compound Annual Growth Rate (CAGR) of 23.3%. Until 2011, approximately 17% of the total wind repowering potential had been explored globally.

Power Electronics for Wind Turbines

44GW in 2011, every year beats the predictions, but it may not last…

In 2011, almost 44GW of wind energy has been installed in the world and half of it was in China. Each years’ results are greater than predictions, and it has been so for the last 10 years. But we envision a slow down in this growth, fully explained in this report: 22% annual growth is huge. Based on the history, we believe the market will stay between 15% and 20% growth until 2015. Compared to all other power electronics markets, this is still the biggest opportunity for this type of converters in power electronics.

There are other main trends at the macroscopic level:
  • European on-shore market is now close to maturity. EU countries are now starting to conquer and equip their off-shore potential.
  • Emerging markets (South America and Asia) are starting to equip themselves to feed their grid with green energy.
Turbine architecture is changing, and converters with them. We aim at greater efficiency and reducing O&M (operating and maintenance) costs. Permanent magnets, no-gearbox and full converters seems to be the ideal combination, if material costs stay stable.

Converters are also more demanding, and thus more power electronics is required: converter market is at $4.5B today, and will top +$5.5B in 2017.
The next five years are still on high growth, thanks to the technology evolutions detailed in this report.

Integration and modularity” trend is redesigning the supply-chain
Converters manufacturing and supply-chain is in the middle of a major evolution: modularity and integration. Rather than supplying one passive components, we expect to see more and more companies to merge with partners, and provide a pre-assembled stack, where only the power module would be missing. You can then easily design and maintain a converter using and replacing these “bricks”. This type of assembly is more and more used in high power electronics. Companies such as Mersen, Methode electronics,… are positioning towards this new type of business model. This evolution is fully described in this report, highlighting the passive components, their importance in the converter, the future trends to come…

Moving From DFIG to Full converter has a Large impact on passives

The supply-chain is moving, and you will get the tools to understand this evolution in this report: With the integration trend, we will see more and more companies manufacturing or supplying several passives at a time, assembled together, to gain in added value. The components are to be pre-assembled in stacks, and the final integrator will choose the power switch.

Laminated busbars are fully part of this integration trend as they connect all these components together. Mersen announced recently the acquisition of Eldre, third player of the busbar market. On the other hand, Chinese players such as Eagtop, or CSR are gaining in experience of laminated busbar manufacturing. Globally, the market is on growth trend reaching $44M in 2017, following the need of higher power converters.

According to most players, the capacitor market is not expecting a technical breakthrough, but footprint and integration skills will give advantage to the players who mastered it. The polypropylene film shortage is now over, and the market is not as tense as it used to be.

The resistor market is suffering from the move to full converter design. The design of grid fault protection systems requires less very high power resistors, and thus, the crowbar resistor market will diminish by 7% in the 2010-2017 period. DC link chopper is using the same technology and the move will fuel this 16% growth market.

Globally, technical evolutions have very high impact on passive components market. But these impacts, detailed in this report, are very different from one to the other.
