Total Energy Generation

Conventional sources dominate the electricity generation in India. India’s total electricity generation has increased from 1110.45 BU in 2014-15 to 1371.38 BU in 2018-19 which is a compound annual growth rate of 5%. Generation from conventional sources has increased from 1048.67 BU in 2014-15 to 1246.13 BU in 2018-19 which is a CAGR of 4% and generation from renewable energy sources has increased from 61.78 BU in 2014-15 to 125.25 BU in 2018-19 which is a CAGR of 19%.

From the CAGR it is evident that the share of RE in total generation has increased while that of conventional sources in total generation has decreased. More specifically speaking, the share of conventional sources in total electricity generation has decreased from 94.44% in 2014-15 to 90.87% in 2018-19. On the other hand, the share of renewables in total generation has increased from 5.56% in 2014-15 to 9.13% in 2018-19.

Electricity generation from wind technologies has increased from 33.77 BU in 2014-15 to 62.03 BU in 2018-19. The same for solar has increased from 4.60 BU in 2014-15 to 39.27 BU in 2018-19, for biomass has increased from 14.95 BU in 2014-15 to 16.33 BU in 2018-19, for small hydro power has increased from 8.06 BU in 2014-15 to 8.70 BU in 2018-19, for waste to energy has increased from 0.41 BU in 2014-15 to 0.43 BU in 2018-19. However, the share in a total generation has increased only for solar technologies from 7.44% in 2014-15 to 30.97% in 2018-19. The share in total generation for all other technologies has decreased over the same time period.
