How much CO2 does a lignite power plant like those in Barmer emit per kWh?
More than the grid average, because lignite carries more carbon per unit of energy and plants run at modest efficiency. Use the station's figure from the CEA CO2 database. A factory buying from the grid still uses the grid factor of 0.710, not the station's.
Why lignite is higher
- IPCC default of about 101 kg CO2 per GJ for lignite, against about 95 for bituminous coal.
- High moisture lowers plant efficiency, so more fuel is burned per kWh.
Where to find the station figure
The CEA CO2 Baseline Database lists emissions per kWh for each grid-connected station, including lignite plants. Use the latest version and note it.
For your own Scope 2
Unless you have a dedicated supply line from the plant, your electricity comes from the grid, and the national grid factor of 0.710 kg CO2 per kWh applies.
What Senseible does here
Senseible reads fuel, electricity and production documents into dated, fingerprinted plant records, so the monthly intensity behind a figure can be traced to its source.
