What grid emission factor should a supplier in Peru use?
Peru's power comes mainly from hydro and natural gas from Camisea, with a growing share of wind and solar, so its factor sits between a hydro and a gas grid. Use the official or IEA figure for the reporting year and name it.
Which figure
- Location based: the national grid average for the reporting year, from the official source or the IEA.
- Market based: a supplier specific figure or residual mix, only if one exists for Peru.
- Write down the figure, its source and its year.
Why it moves
Dry years cut hydro output and gas plants run more. Mines on dedicated contracts should use the factor for their supply.
Records
Monthly electricity bills with kWh, and meter readings for any power you make on site.
What Senseible does here
Senseible reads electricity bills into dated, fingerprinted records and keeps location based and market based figures side by side, each with the factor and year used.
