Despite the massive challenges it faces now with Covid-19, India is the world’s fourth-largest wind power generation capacity with an estimated wind power potential of 302 GW at 100 meters above ground level.

India’s potential has already attracted the world’s biggest sovereign wealth funds and private equity investors to invest in the country, the Mint article reports.

Slowing wind speed trends

India’s monsoon season between June and September typically brings along wind speeds ranging between 23 kilometres and 29 kilometres per hour, which fuels its wind turbines to generate electricity. It is also during the monsoon season that two-thirds of its total wind energy is generated.

However, the 2020 season showed the slowest wind on record at an average wind speed of between 20 to 27 kph, and the lowest in 100 years, according to Praveer Sinha of Tata Power Ltd.

According to the article, slow winds have reduced windmills efficiency measured in capacity utilization factor (CUF) from 20% from a previous couple of years to 17% at the end of the financial year in March 2021.

Climate change and wind speeds

Climate change is altering the wind patterns, and they hope last year’s slow winds would not become a trend as it can affect India’s transition to renewable energy transition.

According to Madhya Pradesh, chief meteorologist at a weather forecasting company, climate change affects low wind speed. He says that the intense heatwaves in May and June over central India are causing fast wind speeds, but they did not experience it last year. Pradesh is concerned that this year’s low temperature could be a repeat of last year’s phenomenon.

Wind energy is a crucial element to achieving India’s low carbon goals. Still, the recent issue of wind availability is posing a challenge to its renewable energy targets if the trend continues.

According to the article, India has pledged at the 2015 Paris Agreement that by 2030, 40% of its installed power will come from solar, wind, biomass, and hydropower, giving them a carbon reduction of 35%.

As part of the plan, the government targets to build 175 gigawatts of renewable energy capacity by 2022, including 60GW of wind power. At the end of March 2021, its wind energy capacity has reached 38.78GW.

Building more wind capacity spreading out the risk

Plans to “de-risk” the wind energy sector are already in motion as recent trends in low-wind experience is being observed.

Malcolm Wrigley of CLP India says that the key is to focus on wind projects that consider a broader long-term wind forecasting and not just the low-wind experience of a single outlier year”.

The strategy is to follow a portfolio approach to wind assets as “Wind will vary from site to site, and year to year and the only way to mitigate this risk is to own a portfolio that is across the country”, according to Malcolm.
