India is one of the largest in the terms of population. Thus, the demand for power is extremely high. This factor has triggered the rise of several types of power agencies to fulfill the requirement. In general, the power department of the country falls directly under the Ministry of Power India. The name of the ministry was Ministry of Energy in earlier times. Ministry of Power covers the entire sector of power. The huge variety of the climatic conditions of the country has forced the country to depend on various sources of power. All these types fall directly under the power department. The sub divisions are organized in such a manner, that they are able to interchange among themselves to be able to meet the exact requirement.

However, the hard side of the entire affair is the fact that, the power department of India has not been able to meet the entire requirement till date. This factor has forced the government to look at various other sources of power as well. Mainly the thermal power is the major source of power of India. Other than the thermal source, India is able to generate hydro electric power, wind power, solar power and several other non conventional power sources. The power source to use completely depends on the region in question. The general landscape of the region would dictate the power source in a huge way. The largest source o power in the country is the thermal energy and thus, coal department happens to be a very important department in more ways than one. 

The entire sector completely depends of the availability of coal and the price tag attached. The central electricity authority is the major coordinating body for the ministry of power. The companies tagged within this bracket are mostly government organizations. However, there are certain private power companies as well. Along with the central electricity authority, there are several other organizations which must be named in this regard. The National Hydro Electric Corporation (NHEC), National Thermal Power Corporation (NTPC), Nuclear Power Corporation of India Limited, Power Finance Corporation of India (PFCI), North Eastern Electric Power Corporation (NEEPC), Damodar Valley Corporation (DVC), Rural Electrification Corporation (REC), Bhakra Beas Management Board (BBMB), Satluj Jal Vidyut Nigam (SJVN), Power Grid Corporation of India Ltd (Power Grid India), Tehri Hydro Development Corporation (THDC), Bureau of Energy Efficiency (BEE) and Power Trading Corporation (PTC) are some of the organizations which would fall in this bracket. All these combined fall under the ministry of power India.

It is a massive department and the entire development of the country depends a lot on this department. Mainly, the funds and the finances are provided by the government of India. However, there are certain private companies like Reliance power, which have been able to hit the market. Finances are also obtained from the World Bank and other financial sources. Mainly, the Power Finance Corporation ltd India is responsible for all the finances.

This organisation is responsible for funding any new project. The most important thing to plan in this sector is the scope for future power stations. It is extremely important to generate more power in lesser time and with the help of lesser raw materials. This is where; nuclear power comes into the picture. The issue still lies with the government to sanction. However, it might prove to be the perfect stepping stone for the future world. There are authorities which are on the lookout for better alternative sources of energy.

The renewable ones are the most researched ones. Solar energy is being tried in various parts of the country. However, a bad side to the energy is the time taken for production and the initial cost factor attached. The thermal power plants in India are the most popular ones. However, this is a form of non renewable source of energy and need to be replaced soon. There are certain solar power units in the country as well. The solar power units take a lot of space and time for the entire production process. There are several wind power units as well. However, these units are very much dependent on the location. Thus, this source of energy cannot be generalised. The net contribution of this source to the total power consumption of the country is extremely low. Hydro power units in India are also extremely common. There are several hydro power dams in the country. The Bhakra Nangal dam and the Damodar valley dam are two examples of this hydro electric power. This source is also based on water supply and cannot be generalised.

The nuclear power units are said to be the future of the country. There are several nuclear power units under construction in the country. The cost factor tagged with the unit is extremely high. Thus, financial budget might be a problem in going for this power source. Bio gas production in India is a very god nature friendly mode of power generation. However, in India, the entire concept is still not being implemented correctly. It is also said to be a vital future source of energy. There are several power sector companies in India. However, some of the most important companies are being listed below.
