Power Companies India: With great power comes great responsibility. Besides responsibility, it also creates the framework for an entire country, as almost every single industry today, is dependent on energy and power supply.

For the longest time, most of India, especially the underdeveloped regions lived in darkness as electrifying an entire country is time-consuming, not to mention very expensive. 

In recent years, India’s shift to focus on green energy, solar power generation, and other renewable energy alternatives has been making headlines.

For our informative blog on the power sector, we bring you “Power Companies India”, highlighting the power industry in India, and some of the top companies that have a sizable presence in a sector that is responsible for quite literally, powering up an entire country.

Power Industry In India

Prior to the recent boom in investments in the renewable energy sector, India’s energy needs were mostly fulfilled by coal combined with heavy imports of energy, oil, and other forms of energy.

India is the 2nd largest producer of coal on the globe.  Even in 2022, 58.6 percent of India’s thermal power installed capacity ( Of a total of 236.1 GW) comes from coal, and the remaining comes from diesel, lignite, and gas. 

However, in the recent decade, new developments have come up in India’s attempt to shift its energy dependency to more sustainable and greener energy sources such as hydro, solar, and wind, aside from alternatives to fossil fuels such as CNG and LPG.

From Solar, wind, hydro, and biopower alone, electricity generation has gone up from 193.5 billion units (2013-14) to 306.5 billion units (2020-21). 

India is both the 3rd largest producer as well as consumer of electricity in the world.
