Frequently asked questions
You can enter the biomass percentages yourself in MyVertiCer. You can do this on the ‘Fuel percentages’ tab.
Please note the following: do not click ‘Agree’ until you have entered your biomass records correctly and in full.
If it turns out that the data has not been entered correctly or is incomplete, you can correct this yourself when submitting the annual report (by 30 April for the previous calendar year). Should you make a mistake whilst entering the data, please contact us and we will help you to correct it.
Do you produce thermal energy? If so, please ensure that, in addition to entering your fuel percentages, you also upload your monthly measurement report (in PDF format) to MyVertiCer.
Electricity producers can view the measurements in the “old” MyVertiCer. Select the appropriate login method below:
Producers with eHerkenning: click here.
Private individuals with IDIN: click here.
Private individuals with OwnIDP: click here.
Producers of green gas and thermal energy can now view the measurements in our new MyVertiCer portal. To view the measurements, login via the “Login MyVertiCer” button at the top of our homepage or via the “Self-service” menu option. Select your role (Producer) and then select the option ‘I want to view my thermal and/or green gas measurements’. Here you can find the measurements sent by your metering company from 6 January 2026 onwards.
Contact your grid operator or metering company.
At the end of the year, you may make a one-time correction to the certification scheme you have declared, such as ISCC and BetterBiomass. This should be done when submitting your annual report (management statement or assurance report). The deadline for submitting this document is 30 April of the following year.
If, by any chance, you have made a mistake when entering the data, please contact us and we will help you to correct it.
Once the measurement data has been received and the fuel percentages have been entered, GOs are issued. At the end of the year, you may make a one-time correction to the fuel percentages. This is done when submitting your annual report (management statement or assurance report). The deadline for submitting this document is 30 April of the following year.
If, by any chance, you have made a mistake when entering the data, please contact us and we will help you to correct it.
This can have several causes:
- Check your metering data
Contact your grid operator (for electricity) or metering company (for green gas, green hydrogen, or thermal energy) if no or incorrect metering data has been provided.
- Check if you have a valid registration in MyVertiCer
Your production installation registration is valid for 5 years. Check if your registration is still valid. If it has expired, register your production installation again via MyVertiCer. This can be done retroactively to January 1 of the previous calendar year.
- Change trader
If your current trader is no longer registered in MyVertiCer, select a new trader from the Trader Overview and update this in MyVertiCer under ‘Mijnproductie-installaties’. The GOs will then be issued retroactively.
If you have checked the above points and everything is correct, please contact VertiCer.
An overview can be found under Downloads.
For electricity, the grid operator is responsible forsubmitting metering data to VertiCer.
For thermal energy, green hydrogen and green gas, this is your metering company.
Contact your grid operator. For thermal energy, green hydrogenand green gas, contact your metering company.
If you submit your report even one day late, we are required to reduce the number of GOs by 1/365. This reduction increases for each additional day of delay. This is stipulated in the regulations of the Ministry of Climate and Green Growth.
A metering report contains metering data and/or information about biomass streams used. It substantiates the energy produced.
A metering protocol describes the production installation, energy flows, and how measurements are taken. It includes information about the location, installations, measurement accuracy, and the metering company. The protocol is valid for 5 years and must be updated when changes occur.
Some installations use multiple types of fuel. Biomass percentages indicate the share of energy from each source, expressed as percentages.
These characteristics cannot be changed. Please check your input carefully.
If you have the value for greenhouse gas emission reduction (also called carbon intensity) in gCO₂/MJ, convert it to kg CO₂eq/MWh to comply with the AIB standard. Multiply the available value by 3.6.
For each NTA code entered in MyVertiCer, only one country of origin can be specified. This is a deliberate choice by VertiCer to keep input stream data on GOs clear. The number of GOs issued remains the same.
