AWS Truepower, LLC, an international leader in renewable energy consulting and information services, in its latest installment of India’s Wind Trends Bulletin, a quarterly analytical wind report for the first quarter said near normal speeds were experienced across western India. However, parts of the Western Ghats and Deccan Plateau observed above normal values.
According to the report, in much of Northern and Eastern India, wind speeds at 80 m above ground level during the first quarter of 2012 were well above-normal relative to the long-term (1997 – 2012) average.
Near to below-average values occurred across most other regions. The wind resource was furthest above-average in Uttar Pradesh and Bihar (+20% or more); it was furthest below-normal in southeastern coastal areas (-15% to -10%).
In the parts of the Western and Southern Ghats, the wind resource was 15% or more above-average. During March, the Western Ghats and higher elevation parts of the Deccan Plateau experienced above-normal wind speeds (+5% to +10%), while below-average values (-10% to -5%) were observed elsewhere across this region. In addition, wind speeds were near-normal (-5% to +5%) in Gujarat and Rajasthan.
For the 12-month period from 1 April 2011 to 31 March 2012, wind speeds were predominantly near to below-normal, except for parts of Northern and Eastern India where small (0% to +5%) positive anomalies were observed (see map below left). In parts of Gujarat and Rajasthan, speeds were furthest below-normal (-10% to -15%). Wind speeds have generally increased across India over the past twelve months relative to the previous year; only in some western areas (Gujarat and Rajasthan) has the wind resource decreased over the same period, the report adds.
