What grid emission factor should a supplier in Taiwan use?
Taiwan grid power comes mostly from gas and coal, with growing solar and wind, so the location based factor sits around half a kilogram of CO2 per kWh. Use the figure the energy authority publishes for the reporting year, state source and year, and report RECs or PPAs under the market based method.
Location based
The official figure is published yearly and has been easing as renewables grow. Use the year that matches the bills.
Market based
Taiwan RECs or a corporate PPA retired for your consumption set this figure, if they meet the Scope 2 quality criteria.
What to send
- Monthly kWh from bills.
- Both totals, with factor, source and year.
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.
