Does CEA's grid emission factor include captive power plants?

Partly. Since FY 2022-23 CEA includes electricity that grid-connected captive plants inject into the grid: 18,882 GWh in FY 2025-26. Captive power a factory generates and uses itself is not in the grid factor, so count that from your own fuel records, not at 0.675.

What CEA counts

• Captive power injected into the grid: 17,342 GWh in FY 2022-23, 16,400 in FY 2023-24, 18,695 in FY 2024-25 and 18,882 in FY 2025-26.
• Emissions attributed to that injection: about 17.5 million tonnes CO2 in FY 2025-26.
• Version 22.0 replaced provisional captive data for FY 2024-25 with actual data.

How to split your own electricity

1. Grid units from the DISCOM bill: apply the CEA weighted average for that year.
2. Captive units generated and used on site: calculate from the fuel burned, as Scope 1.
3. Units bought from another company's captive plant: use that plant's figure if you have it, or the grid factor if you do not, and say which.

What Senseible does here

Senseible reads DISCOM bills and fuel invoices into separate dated records, so grid units and captive generation are counted once, in the right scope.

• DG set vs grid per kWh
• Coal power CO2 per kWh
