The Netherlands Authority for Consumers and Markets (ACM) has revealed that all energy suppliers in the country now provide accurate information about the origin of electricity, following inspections that prompted three companies to update their data.
The ‘electricity label’, which indicates whether electricity is generated from renewable sources such as wind and solar energy or from fossil fuels, is intended to improve market transparency and help consumers make informed choices, according to the ACM. The electricity label shows the origin of the electricity supplied, whether it is green (renewable) or gray (fossil), to help consumers make informed choices. ACM says that the electricity label improves market transparency and helps consumers make informed choices.
ACM requires suppliers to publish the label online before May 1 every year to verify that claims for green energy correspond to Guarantees of Origin (GoOs) or Certificates of Origin (CoOs). Recent inspections found that two unspecified suppliers had previously misreported this data, prompting the regulator to require monthly disclosures from them.
Energy supplier Zonneplan has also reported the ACM for providing insufficiently clear information. The company now explicitly indicates that it supplies gray energy, while the app and dynamic contracts encourage customers to shift consumption to periods when the availability of green energy is high. In April 2025, based in Zwolle Solar plan has started to offer owners of solar panels an extra bonus for the electricity they feed back into the grid, with the aim of encouraging their contribution to the energy transition, according to the website. The company also noted that dynamic energy contracts, which align electricity consumption with periods of high green energy availability, can maximize financial benefits for households.
In March, ACM launched an investigation into how Dutch energy suppliers determine the feed-in costs for households with rooftop solar energy, following a 10% increase in the past month and reports of net negative compensation payments. The regulator said it will assess whether pricing practices are reasonable and monitor fairness ahead of the country’s planned end to net metering in 2027.
