Methodology
All the data provided on this website is compiled and collated from various government sources, Central as well as State, and also includes State and Central Regulatory Commissions and other Government Institutions such as the Central Electricity Authority, Solar Energy Corporation of India etc. Further, the data was largely taken from publicly available information such as publications of the various government departments and agencies or from their websites.
However, in some cases, data has been derived or assumed. These have been clearly footnoted in the respective sections along with the formula that have been used for the purpose. In some cases, we have clearly stated, that the numbers could be “indicative” and would be updated, as and when, the actual data is available in public domain.
Since the information available on this website covers all sources of electricity generation, there are some data points that are common, irrespective of the source of generation, such as geographical information, district water levels, air quality index taken from State and Central Pollution Control Board’s monitoring stations.
Further, data on the power sector is available from various authorities and agencies such as the Ministry of Power, Government of India, Central Electricity Authority, Power Systems Operations Corporation Limited (POSOCO), Solar Energy Corporation of India (SECI), Ministry of New and Renewable Energy and so on. Therefore, to ensure uniformity of information, we tried to source information as far as possible from only Central Electricity Authority (CEA) for information on thermal power and a combination of data from CEA and SECI for information on Renewable Energy. However, we have tried to validate the authenticity of information we have used from other sources wherever possible.

CO2 Emissions | This data was derived using the emission factor of 0.989kg/kWh for Coal based power plants, 1.37 kg/kWh for Lignite based power and 0.45 kg/kWh for Gas based power plants The emission factor was taken from Central Electricity Authority’s (CEA) Baseline Carbon Dioxide Emission Database Version 15.0. The Emission figures are only indicative and cannot be taken as the actual emissions, as we have not factored in the kind of coal and its calorific value, the boiler type, other fuel used such as starter fuels, the frequency of start and stop and so on to estimate the plant level or unit level emissions. | Derived and Sourced, CEA Link to CO2 Baseline Database for the Indian Power Sector Report, https://cea.nic.in/wp-content/uploads/baseline/2020/07/user_guide_ver15.pdf |
Proposed Power Plants List | The approach followed was to list out details of all applications put forth by Power Producers for permissions to set up Thermal Power Plants (Terms of Reference and Environmental Clearances). This data was taken from the Parivesh Website of the Ministry of Environment, Forests and Climate Change. For further information on plants that are in various stages of construction and commissioning, the data was sourced from Central Electricity Authority. | Sourced and Derived Link to Parivesh dashboard: http://parivesh.nic.in/ |
Fuel Linkage Linkage for Gas power plants | For gas power plants the data for fuel linkage and gas requirement was taken from the Environmental clearance and Environmental Impact Assessment reports , sourced from Ministry of Environment, Forest and Climate Change (MoEFCC) | Sourced |
Source of Coal | The data for the Source of Coal, is Plant wise data, which has been taken from the Environmental Clearance (EC)s and Terms of Reference (ToR)s. | Sourced |
Coal Consumption | For coal consumption, we sourced the monthly coal consumption data for all coal fired power plants from the Central Electricity Authority Fuel reports- report. We have this data from the years 2015-2016 to 2020-2021. | Sourced Link to monthly coal consumption data: Refer to Fuel Reports: https://cea.nic.in/old/monthlyarchive.html |
Coal Usage per Unit generated (in Kg/ kWh) | For Coal usage per unit generated, we took the Coal consumption values from the monthly Fuel Report and the gross Generation values (factoring in auxiliary consumption + net generation (plant wise generation values)), we calculated the coal usage per unit generation in kg per kilowatt -hours.The data for Coal Usage per Unit generated is indicative. | Sourced and Derived |
Power Purchase Cost | The power purchase cost data was taken from the tariff orders for the DISCOMs for the years 2015-16, 2016-17, 2017-18, 2018-19, 2019-20 and 2020-21. The data comprises of fixed cost, variable cost, total costs and other costs wherever given. The data sourced is mostly true-up power purchase cost values and approved values. In some cases, where we have calculated the per unit cost data based on the values available (in the tariff order), for Energy purchased by the DISCOM (in MU) and Fixed or Variable cost values (in Crores) We used the following formula to calculate Fixed and Variable cost at Rs. /kWh: Fixed Cost or Variable Cost = Cost (in crores) divided by Energy Purchased (in MU) In cases where the True up value was not available, we took the Commissioned approved values. Further, in rare cases where the commission approved values were not available, we took the Petitioner’s submitted values for cost. | Sourced and Derived: DISCOM Multi Years Tariff orders |
Power Purchase Quantum | The power purchase quantum data was taken from the tariff orders for the DISCOMs for the years 2015-16, 2016-17, 2017-18, 2018-19, 2019-20 and 2020-21. The data for the Power Purchase Quantum, captures the plant wise data for the Quantum of Electricity Purchase. In cases where the True up value was not available, we took the Commissioned approved values. Further, in rare cases where the commission approved values were not available, we took the Petitioner’s submitted values. | Sourced and Derived: Multi Years Tariff orders |
Date of Decommissioning | The date of decommissioning gives information date/ year when the thermal power plant was decommissioned. The data is based on the list released by the Central Electricity Authority for those plants which have formally retired. But in very few cases, we have also taken those plants which were commissioned and have not been generating for more than 20 years. For example, in case Gas power plants list, we are considering Haldia Combined Cycle Co-Generation Power Plant, as retired power plant, as it has not been generating for more than 20 years, and among the plants which have not generated, Haldia Combined Cycle Co-Generation Power Plant was commissioned in 1979 plant and it was older than Kasba Thermal Power Station (GT) which was commissioned in 1991, so we are considering Haldia Combined Cycle Co-Generation Power Plant, as retired. |

The Annual generation have been calculated by adding the monthly generation data for all sources. The values are derived based on the formula: The PLF, Plant Load Factor was calculated based on generation and installed capacity. The methodology used to calculate PLF = Generation (converted in kWh)/ (24*365 * Capacity of the Plant/ Plant Unit) *100. This formula was used to arrive at the PLF in percentage. In case of Coal, it may vary from the Home Page numbers since it is sourced from the Ministry of Power website. |
