Generation, export and carbon are not the same thing
It is tempting to add together every kWh generated and convert it to tCO2e. In practice, the carbon treatment differs depending on whether the electricity was self-consumed on site or exported to the grid, and depending on who has contractual right to the environmental attributes.
Three positions that hold up
- Self-consumed kWh: defensible Scope 2 reduction for the consuming party under both location- and market-based methods.
- Exported kWh under a PPA where the off-taker retains the environmental attributes: belongs to the off-taker, not the landlord.
- Exported kWh under SEG without attribute transfer: revenue belongs to the landlord; carbon claim is constrained.
These distinctions need to be recorded against each site, not assumed. Export Management and Reporting record export volumes and apply the correct treatment automatically.
