Did CEA version 22.0 change the grid factors for earlier years?
No, not at the published precision. The FY 2024-25 weighted average stays at 0.710 t CO2 per MWh in both versions, the combined margin stays at 0.736, and FY 2021-22 to FY 2023-24 are also unchanged. Version 22.0 adds FY 2025-26 at 0.675, so past footprints need no restating.
Weighted average, t CO2 per MWh
- FY 2021-22: 0.711 in both versions
- FY 2022-23: 0.716 in both
- FY 2023-24: 0.727 in both
- FY 2024-25: 0.710 in both
- FY 2025-26: 0.675, new in version 22.0
Margins for FY 2024-25
- Operating margin 0.961 in both versions
- Build margin 0.512 in both
- Combined margin 0.736 in both
What this means
Version 22.0 recalculated FY 2024-25 with actual captive power data, but the rounded figures CEA publishes did not move. If you reported FY 2024-25 at 0.710, there is nothing to restate.
What Senseible does here
Senseible reads electricity bills into dated kWh records per meter and site, so whichever CEA factor and version you apply, each Scope 2 figure traces back to the bill and the factor behind it.
