NIS2 for energy companies in the Netherlands

Energy is listed in Annex I of the NIS2 directive. Large companies are essential entities; medium companies are important entities. In Netherlands, the rules come from the Cyberbeveiligingswet (Cbw — Cybersecurity Act), applicable since 15 August 2026; the authority is the National Cyber Security Centre (NCSC) runs the register; supervision by the Rijksinspectie Digitale Infrastructuur (RDI) and the sector supervisors.

Who is covered in this sector

• Electricity producers, suppliers, network operators, aggregators and storage operators
• Operators of EV recharging points serving end users
• District heating and cooling
• Oil, gas and hydrogen: production, storage, transmission, supply

Companies that only consume energy are not in scope because of that; a solar installer is not an energy operator (see the Cyber Resilience Act page if you sell connected devices).

The threats we see most in energy

• Ransomware that stops dispatching, billing or metering
• Attacks on remote access to substations, inverters or charging points
• Compromise through an OT maintenance supplier
• Phishing of control-room and field staff

Five priority measures

1. 01 Separate office IT from operational technology (OT) networks
2. 02 Inventory every remote access path and put MFA on it
3. 03 Test offline backups of billing and control systems
4. 04 Contractual security clauses with OT and maintenance suppliers
5. 05 A 24-hour incident reporting routine tested once a year

What Netherlands requires

• The Act entered into force on 15 August 2026, together with the Critical Entities Resilience Act (Wwke).
• Registration in the national register (Mijn.NCSC.nl) is mandatory since 15 August 2026: name, address, sector, EU countries served, contact details and, where relevant, IP ranges.
• Cloud, data-centre, DNS and managed-service providers register where their head office is; other entities register in every EU country where they operate.
• The duty of care (risk management) and the duty to report significant incidents apply from the same date.
• Non-compliance can lead to fines and to orders subject to a penalty payment (last onder dwangsom).

Significant incidents: early warning within 24 hours, notification within 72 hours, final report within one month. Fines set by the directive: up to €10 million or 2% of worldwide turnover for essential entities, and up to €7 million or 1.4% for important entities (whichever is higher).

Frequently asked questions

Energy is an Annex I sector. Large companies are essential entities; medium companies are important entities. Small companies are generally out of scope unless designated. Our NIS2 check gives you the answer in two minutes.

What should we do first?

Register if you are in scope, name an owner, run a short risk assessment, and fix the basics: MFA, tested backups, patching, incident routine.

We are a supplier to this sector. Does it affect us?

Yes, indirectly: your customers must secure their supply chain and will ask you for evidence. See our supplier questionnaire guide.
