# What grid emission factor should a supplier in Peru use?

Canonical: https://senseible.earth/answers/peru-grid-emission-factor-for-suppliers

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.
