Electricity label
As a business end user with a supply contract with an energy company, you have the right to know the origin of the electricity you use. This is proven by a Certificate of Origin (CoO) or a Guarantee of Origin (GvO). We have summarised the origin of the electricity you consume in an ‘electricity label’.
Why is it important for your business?
The electricity label gives you, as a business customer, insight into the origin of the electricity you consume
You can use the button below to see our electricity label from 2023. At that time we were still operating under the name PZEM Energy Company B.V. (more information here).

About EP NL – Energy for business
EP NL is a Dutch energy company with roots in Zeeland and a focus on the business energy market. Our organisation rests on three pillars: production, trading and supply.
- Production: We produce our own electricity at our own production sites.
- Trade: We trade the energy we produce on the European energy markets.
- Supply: We supply electricity and gas to business customers in the Netherlands.
Since February 2025, we have been operating our trading and supply activities under two brand names:
- EP NL energy – for business energy contracts and supply
- EP Commodities – for energy trading and optimisation.
Both units are part of the same organisation and report to EP Commodities B.V., which in turn reports to the parent company EP NL. From our base in Middelburg, we work to ensure a reliable, affordable and sustainable energy supply for businesses.
FAQ
-
What is a Certificate of Origin (CoO)?
A CoO shows that electricity was generated from fossil sources such as natural gas or nuclear power. EP NL offers CoOs for Dutch gas power plants and nuclear energy to guarantee the origin.
-
Are there any additional costs due to the obligation of CFOs?
Yes, the obligation to use CoO’s to substantiate non-renewable energy may entail additional costs. Energy suppliers have to register with VertiCer and adjust their systems for purchasing, applying (if they own production facilities) and cancelling certificates. In addition, it takes them time to manage, transfer and cancel their CoA portfolio monthly to substantiate their deliveries.
The price of a COO depends on supply and varies between the rate VertiCer charges for the creation of CoOs and the value of the marginal foreign Guarantee of Origin (GoO). It is advisable to consult your supplier for specific rates
-
Why these legislative changes to Certificates of Origin?
Guarantees of Origin (GOs) already provided insight into the origin of renewable energy. However, for electricity generated from fossil fuels such as natural gas, coal or nuclear, this system did not yet exist, leaving the CO2 footprint of this electricity unclear. With the introduction of Certificates of Origin for all electricity deliveries in the Netherlands, both consumers and businesses will have full transparency about the origin of the electricity they purchase.
-
How will this change in law to Certificates of Origin be put into effect?
The Certificate of Origin (CoO) system is similar to the Guarantees of Origin (GvO) system. Any power plant that generates electricity and delivers it to the grid can register with VertiCer. Based on the quantity of energy supplied, the power plant receives Certificates of Origin. These certificates can then be used to substantiate the supply of electricity to end users.
-
What is VertiCer?
VertiCer is a subsidiary of N.V. Nederlandse Gasunie and TenneT TSO B.V. and has been tasked by the Minister of Economic Affairs to issue Guarantees of Origin (GoOs) and Certificates of Origin (CoOs). VertiCer acts as the central point for certification and ensures that the certification system provides insight into the origin and technology of renewable energy.
-
What is the difference between an IMP and a CoA?
GVOs represent green power (sustainably generated), while CoOs refer to grey power (fossil energy sources).
-
What is the difference between CRSs and CoOs?
CSRs represent green power (sustainably generated), while CoOs refer to gray power (fossil energy sources).
-
Distribution of wind energy between the Netherlands and the EU
EP NL supplies a mix of Dutch (0.68%) and European wind power (8.30%), which collectively constitutes 8.98% of the power supplied.
-
What does my supplied electricity consist of?
In the Netherlands, electricity is generated from natural gas, coal and uranium (nuclear). We also generate electricity from the sources of wind, water, biomass and solar.
As an EP NL customer, you can always see where your electricity comes from. This is because it is clearly stated on the electricity label that we publish every year.
-
Why is there a power label?
The power label provides insight into the sources from which EP NL’s electricity is generated. It allows end-users to check whether their electricity is renewable or from grey sources.
-
What if demand exceeds production? From which countries can CoOs then be bought?
Both GoOs and CoOs can be imported or exported, provided the country concerned is a member of the European Union (EU) or a signatory to the European Economic Area (EEA) Treaty. In addition, the country must be a member of the Association of Issuing Bodies (AIB), which oversees the standardised system: the European Energy Certificate System (EECS).
-
What does full disclosure mean in energy supply?
EP NL applies ‘full disclosure’, which means that the origin of both green and grey power is fully transparent. This makes energy supply more transparent for end-users.
