What is the consumption of purchased or acquired electricity, heat, steam, and cooling from renewable sources?
CSRD
Steps for Calculation:
Identify Renewable Energy Sources:
Determine the amount of purchased or acquired energy that comes from renewable sources. These could include:
Purchased electricity from renewable sources (e.g., wind, solar, hydropower).
Purchased heat (e.g., district heating from renewable sources).
Purchased steam (e.g., industrial or district steam generated from biomass or other renewable sources).
Purchased cooling (e.g., cooling from a district cooling system powered by renewable energy).
Gather Data on Purchased Energy:
Collect data on the quantity of electricity, heat, steam, or cooling that your company has purchased or acquired from renewable sources during the reporting period.
This data can typically be obtained from:
Electricity invoices or reports from your electricity provider indicating the renewable energy portion of your supply.
Energy supplier contracts or green energy certifications if you purchase renewable energy or heat.
District heating/cooling suppliers, if applicable.
Convert Energy Data into Common Units (kWh or MJ):
If the purchased energy is reported in different units (e.g., therms, BTUs, or tons of steam), convert everything to a common unit like kWh or MJ for easier aggregation.
Use conversion factors where necessary. For example:
1 kWh of electricity = 1 kWh.
1 ton of steam = approximately 2,900 kWh (depends on temperature and pressure).
1 ton of cooling = approximately 3.5 kWh.
Calculate Total Consumption from Renewable Sources:
Sum the energy from all renewable energy sources (electricity, heat, steam, cooling) to get the total consumption from renewable sources.
