The biggest challenge for India’s Renewable Energy targets is the intermittent nature of Wind and Solar technology, writes a power sector expert.
India remains the fastest growing economy with GDP upwards of 7 per cent and growing population. With increasing urbanisation and growing needs and demands, the energy requirement is also growing at a CAGR of 5 per cent from FY2010.
The capacity addition in the 11th plan (2007-2012) has been 50GW and that in 12th plan (2012-2017) and beyond is close to 130GW. The main contribution for this significant capacity addition (CAGR 10.5 per cent) has come from the private sector, which now has the largest share of 145GW followed by state sector with 104GW and remaining with central sector. With the significant capacity addition, the energy deficit which was 10 per cent in 2009-10 has reduced to 0.6 per cent in 2017-18 and the peak power deficit from 12.8 per cent to 0.6 per cent in 2017. The present energy generation in the country is close to 1300TWh with 330GW of operational capacity comprising mainly fossil fuel 225GW, Hydro 45GW and Renewables 55GW. Renewables comprise Wind, Solar Bio mass and Hydro <25MW. With 1.3-billion population, the per capita consumption of electricity is close to 1000KWh/annum – a third of global average.
