Electricity Installed Utilities
In India's electricity sector, utilities are the public or private entities responsible for the public supply of power, while non-utilities are industrial consumers that generate their own electricity for their own use
Utilities include companies engaged in generation, transmission, and distribution for public consumption, and their generation capacity and consumption is tracked as a separate category from industrial self-generation. Non-utility generation is significant, particularly in the industrial sector
The sources of electricity generation in India are broadly classified into conventional and non-conventional. The conventional sources of power generation are thermal (coal, lignite, natural gas, and oil), hydro and nuclear power, whereas nonconventional sources of power generation (renewable energy sources) include solar, wind, agricultural and domestic waste
