Mestro's standardized conversion factors are activated when no real contracts are configured in the portal.
First, what is a standardized factor?
In short, a standardized factor is a form of conversion template where one type of value is transformed into one of a different type. When we talk about a standardized factor, it is an approximated average value of either costs or emissions that is applied to your usage data. This estimates either costs or emissions per unit energy. However, since these factors are generalized by definition, the results from the calculation will not be a 100% match. On the other hand, it might be close enough for many purposes.
TIP: To activate our standardized factors, contact your Customer Success Manager or send a message to Mestro Support via the yellow chat bubble!
Electricity
Cost
Mestro uses the Nils Holgersson report to calculate the average grid costs for electricity per city. It is therefore important that you register the correct location in Mestro Portal. Additionally, the property's location is used to identify the appropriate electricity grid area, collect the associated electricity tax, and the electricity's spot price from NordPool. NordPool is the the Nordic electricity exchange and provides a wide range of market prices.
Cost items included are:
-
Transmission charge
-
Electricity trading charge
-
Electricity tax
Emission factor
We base the electricity emission factor on the Nordic Residual Mix, beginning in 2015. The standardized factor is updated each year as new values are published by the Swedish Energy Markets Inspectorate. This means that your estimated emissions in Mestro Portal can vary even though you use the same amount of electricity.
Do you prefer using the emission factor from your electricity trading contract or another standardized factor, such as the Nordic Electricity Mix? No problem! Read more about how to create your own cost- and environmental agreements using the contracts module. Don't hesitate to reach out to your Customer Success Manager or to support@mestro.com if you require assistance or advice!
District heating
Costs
We use the Nils Holgersson report to calculate the local cost of district heating for the property's location, as we do for electricity. This requires that the property's City is registered in the Mestro Portal. Annual fees are divided evenly across the year.
Cost items included are:
-
Subscription fee/fixed charge
-
Flow charge
-
Energy charge (December-March / April-May / June-August / September-November)
Emission factors
Mestro's base package includes a standardized emission factor for district heating. The factor is calculated as an unweighted average of Swedish district heating companies reported emission factors. Data is sourced from Swedenergy's annual report of district heating emission factors (in Swedish). The factor includes both operational (GHG scope 2) and production and transport of fuel (GHG scope 3) emissions.
Many factors affect local heating requirements and as such the production of district heating varies year by year. Technology and available fuels also affect the emissions. In simple terms, one can say that the colder the weather is during the winter, the "dirtier" the fuels required become to cover the demand for heating. Below we list the past years' factors in gram carbon dioxide equivalents (CO₂e) per kilowatt hour.
Tables can't be imported directly. Please insert an image of your table which can be found here.

If you desire more specific emission factors to calculate more accurate emissions, we offer "real emission factors" from Swedenergy. If activated, your emission calculations in Mestro Portal are based on each district heating facility's emission factor. Clever, right?
Reach out to your contact person or to support@mestro.com to activate real emission factors.
Cooling
Cost
We use the Nils Holgersson report to calculate the local cost of district cooling for the property's location, as we do for district heating. This requires that the property's City is registered in the Mestro Portal. Annual fees are divided evenly across the year.
Cost items included are:
-
Subscription fee / fixed charge
-
Flow charge
-
Energy charge (May-September / October-April)
Emission factor
We apply a standard factor of 12 grams carbon dioxide equivalents per kilowatt hour (12g CO₂e/kWh).
If you wish to use more exact emission factors you need to connect these to the meters using the Agreements Module!
N.D.: We currently don't offer standardized cost factors for water. But you have the option of recreating your own water contracts via the Agreements Module and if you have any tips about how/where we can collect data to create a standardized factor, please reach out to us!
