Gross Generation Utilities
(Source: CEA)
CEA presents trend in Gross Generation, split into Utilities and Non-Utilities
Utilities are organizations involved in power generation, transmission, and distribution, while non-utilities generally refer to the captive power plants that produce power for their own use
This section captures fuel-wise gross generation from Utilities
For 2023-24, total gross generation of Utilities was 1,734,375.1 GWh (Giga Watt Hours), or ~1,734 TWh (Tera Watt Hours, which is same as Billion Units)
For ease of reference, GWh is same as Million Units (MU) and TWh is same as Billion Units (BU)
Coal accounted for 1,294,852.4 GWh (~1,295 TWh), Diesel 400.6 GWh and Gas 31,295.9 GWh (~31 TWh), for total thermal gross generation of 1,326,548.9 GWh (~1,327 TWh)
Hydro accounted for 134,053.9 GWh (~134 TWh), Nuclear 47,937.4 GWh (~48 Twh) and Non-Hydro Renewables 225,834.8 GWh (~226 TWh)
