The biggest reason for the rising demand for these electricity production systems is the substantial demand for the uninterrupted power supply in various sectors.

Demand of generators in power category

Power is among one of the most important components of infrastructure, vital for the economic growth and prosperity of nations. The existence and development of suitable infrastructure is essential for constant growth of the Indian economy.

India’s power sector is one of the most diversified in the world. Sources of power generation range from conventional sources such as coal, lignite, natural gas, oil, hydro and nuclear power to viable non-conventional sources such as wind, solar, and agricultural and domestic waste. Electricity demand in the country has increased rapidly and is expected to rise further in the years to come. In order to meet the increasing demand for electricity in the country, massive addition to the installed generating capacity is required.

Indian power sector is undergoing a significant change that has redefined the industry outlook. Sustained economic growth continues to drive electricity demand in India. The Government of India’s focus on attaining ‘Power for all’ has accelerated capacity addition in the country. At the same time, the competitive intensity is increasing at both the market and supply sides (fuel, logistics, finances, and manpower).

As per reports, for FY21, electricity generation attained from conventional sources was at 1234.44 BU, comprising 1,032.39 BU of thermal energy; hydro energy (150.30 BU) and nuclear (42.94 BU). Of this, 8.79 BU was imported from Bhutan.

NTPC Ltd.’s oldest unit in Singrauli, Uttar Pradesh, has achieved the highest Plant Load Factor (PLF) of 100.24% among all thermal units in the country between April 2020 and December 2020. In FY22 (until September 2021), the total thermal installed capacity in the country stood at 234.02 GW. Installed capacity of renewable, hydro and nuclear energy totalled 101.53 GW, 46.51 GW and 6.78 GW, respectively.

Multifarious initiatives proposed by the Indian government to stimulate the development of various sectors in the coming years. Make in India campaign, development of smart cities, Saubhagya scheme along with housing for all 2022, are some of the major plans which might favour the development of power utilities and development of manufacturing infrastructure verticals in the country. As per Ministry of Petroleum and Natural Gas of India, out of the total diesel consumption, 6-8% was consumed for power generation which includes grid-connected diesel-based power plants of more than 10 MW, captive diesel-based power plants, and diesel generator sets.

There are two predominant categories of electrical generators, those that use non-renewable energy sources, and those that use renewable energy.

While growth in solar energy is a good sign for the country, thermal energy has been the primary source for the power sector, and will continue to remain an important source of power in the future.  Further, given that renewable energy sources are intermittent in nature, a balancing power will be needed to support the grid and even out the fluctuations.  For example, if solar energy is being used in an area, it will require an alternate source for the night time requirement.

.Demand of generators in construction category

Presently, the world is witnessing the increase in the demand for power at a significant pace. Thus, it has become of utmost importance of having a reliable source of power.
