A thermal power generation system is a method of producing electricity by converting heat energy into electrical energy. In a typical system, fuel such as coal, natural gas, or oil is burned to produce high-pressure steam, which drives turbines connected to electric generators. The turbine’s rotation is transformed into electrical power that feeds the grid. This system underlies conventional power generation and forms a core part of how Tata Power’s plants help meet India’s energy needs while working to improve efficiency and lower emissions.
Conventional power plants are electricity-generating facilities that use established energy sources such as coal, oil, natural gas, or nuclear fuel to produce power for the grid.
They generate electricity by -
1. Fuel is burned or used to release heat
2. Heat converts water into steam
3. Steam spins a turbine
4. The turbine drives a generator
5. Electricity is produced and supplied to the grid
In India, conventional power plants provide dependable base-load power, supporting the national grid and meeting large-scale energy demand for homes, industries, and critical infrastructure.
1. Thermal power generation refers specifically to producing electricity by converting heat from fuels like coal, gas, or oil into electrical energy using steam or gas turbines
2. Conventional power generation is a broader category that includes thermal generation as well as other established methods like hydro and nuclear that use traditional fuel sources to make electricity.
3. While all thermal plants are conventional, not all conventional generation systems are thermal.
Thermal power plants in India offer several key benefits that support the nation’s energy system -
1. They provide a consistent and reliable supply of electricity, forming the backbone of India’s power grid.
2. These plants use proven technology and locally available fuels, helping meet large-scale demand.
3. They support economic activity by enabling industrial growth and employment.
4. Thermal plants can be located near fuel and water sources, making them flexible to build.
A thermal power plant project involves the planned development of a facility that converts heat from fuel into electricity for the grid.
Project lifecycle -
1. Planning and feasibility, including site, fuel, and environmental studies
2. Design and engineering of boilers, turbines, generators, and control systems
3. Procurement of major equipment
4. Construction and installation of plant infrastructure
5. Testing, commissioning, and grid synchronization
In India, companies like Tata Power execute such projects to meet large-scale energy demand and support industrial growth.
Conventional electricity generation refers to producing power from well-established energy sources that have long supported national grids. These include non-renewable fuels such as coal, oil (petroleum), natural gas, and nuclear fuel, which are used to create heat that drives turbines connected to generators to make electricity. Large hydroelectric power is also often classed with conventional sources because it has been widely used for decades. These traditional energy types form the backbone of most national electricity systems.
Waste heat recovery in thermal plants is the process of capturing excess heat produced during power generation that would normally be released into the environment and putting it to use. In thermal power plants, this involves using heat from flue gases, steam or hot exhaust to generate additional steam or electricity, improving overall energy efficiency and reducing fuel consumption. It helps lower operational costs and reduce carbon emissions by making better use of energy that would otherwise be wasted.
Tata Power offers a range of thermal energy solutions for industries in India that improve energy efficiency and reduce waste -
1. Supercritical technology operates at higher temperature and pressure to improve fuel efficiency and reduce greenhouse gas emissions compared with lower-grade systems.
2. Subcritical technology is applied to reduce emissions and maximize energy output in some conventional plants.
3. Waste heat recovery systems capture heat from industrial processes and use it to generate additional power, reducing waste and emissions.
4. Zero liquid discharge ensures no industrial wastewater is released, supporting sustainable operations.
5. Flue gas desulphurization removes sulfur compounds from exhaust gases, cutting pollution.
6. Ash utilization practices repurpose fly ash and bottom ash for construction materials, reducing landfill impact.
Tata Power can support large industrial facilities with a reliable thermal power supply by leveraging its extensive generation capacity and advanced technologies. Its conventional power stations, including Mundra Thermal Power Station with over 4,150 MW capacity and other plants such as Prayagraj and Maithon, deliver steady base load electricity across states.
