WIND ENERGY Global Wind Market The World Wind Energy Association’s report looks at the global small wind market. The report’s authors are Stefan Gsänger and Jean-Daniel Pitteloud. Definition of Small Wind Technically, there are several definitions of small wind turbines: The most important international standardisation body, the IEC, defines SWTs in standard IEC 61400-2 as having a rotor swept area of less than 200 m2, equating to a rated power of approximately 50 kW generating at a voltage below 1’000 V AC or 1’500 V DC. In addition to this standard, several countries have set up their own definition of small wind. The discrepancy of the upper capacity limit of small wind ranges between 15 kW to 100 kW for the five largest small wind countries. The major pattern of today`s upper limit capacity leans towards 100 kW. This is largely caused by the leading role of the North American and European market. Over the past decades, a growing average size of the small wind capacity has been observed. This pattern is largely caused by the increasing interest in larger grid-connected systems and a comparatively diminishing market of standalone systems. Nevertheless, in order to create a standardised and healthy small wind market share, an agreeable definition of small wind should be agreed upon. This report intends to bring forward the discussion on the definition of small wind and aims to create eventually a unanimous international classification system of small wind accepted by all parties of the industry. For the purpose of generating comparable graphs, figures and charts in this report, 100 kW is chosen as the temporary reference point. The definition, however, requires further discussion until a globally harmonised agreement is reached. In practise, the major pattern of today’s upper limit capacity leans towards 100 kW, although the IEC defines a limit of equivalent to 50 kW.

Small Wind World Market: Growth at Lower Pace After several years of continuous growth, 2013 was a challenging year for the small wind industry. The three biggest markets suffered a decrease in the number of units installed in a year. As of the end of 2013, a cumulative total of at least 870’000 small ENERGETICA INDIA 60 energética INDIA · NOV | DEC15
