NIS2 incident reporting: preparing for the 24-hour clock

What counts as significant, what’s due and when, and what a charge point operator should set up before an incident.

NIS2 gives entities in scope 24 hours from becoming aware of a significant incident to send an early warning. That’s too short to design a process, so the work has to happen beforehand.

Operators of recharging points are listed in Annex I, subject to size rules. See NIS2 for charge point operators for scope. This guide is general information and isn’t legal advice, and national law sets the details.

What counts as significant

Article 23(3) gives two tests. An incident is significant if it has caused, or could cause, severe operational disruption or financial loss for you. It’s also significant if it has affected, or could affect, others by causing considerable material or non-material damage.

Note the words “capable of causing”. An incident can qualify before the damage happens. For an operator, a rogue firmware job stopped halfway may need the same assessment as a network-wide outage.

Agree your own thresholds with counsel now, and check them against guidance from your national authority.

What’s due, and when

  1. Start

    You become aware

    Of a significant incident. A named person records the moment.

  2. Within 24 hours

    Early warning

    Suspected malicious act, and any cross-border impact.

  3. Within 72 hours

    Incident notification

    An initial assessment of severity and impact.

  4. One month later

    Final report

    Counted from the 72-hour notification. Root cause and mitigation.

ReportDeadlineWhat it covers
Early warningWithin 24 hours of becoming awareWhether malicious acts are suspected and whether there could be cross-border impact
Incident notificationWithin 72 hours of becoming awareAn update, an initial assessment of severity and impact, and indicators of compromise where available
Intermediate reportWhen the CSIRT or authority asksRelevant status updates
Final reportWithin one month of the notificationDescription, severity and impact, likely root cause, mitigation, and any cross-border impact

If the incident is still running when the final report is due, you send a progress report then. The final report follows within one month of finishing your handling of the incident.

In Germany, the BSIG sets these duties out in § 32, and reports go to the BSI. See our regulation tracker for dates.

What to set up now

  1. Name who decides whether an incident is significant, plus a deputy for nights and holidays.
  2. Write down when the clock starts in your organisation, and how you record that moment.
  3. Find your reporting route and test the login. The CSIRT or authority differs by country.
  4. Prepare a short template for the early warning, so nobody drafts from nothing at 3 am.
  5. Keep logs from your back-end, chargers and suppliers with synchronised time.
  6. Put notice periods in supplier contracts, because their delay eats into your 24 hours.
  7. Run a tabletop exercise with a charging scenario, and time how long the decision takes.

Keep the decision as well as the report

Record why you did or didn’t treat an incident as significant, who decided, and what they knew at that moment. If an authority asks later, that record is your explanation.

Article 20 makes management bodies responsible for approving and overseeing risk-management measures. So your board should see the exercise results, along with the process document.

The final report asks for a root cause and the mitigation applied. Both are easier to write from a timeline built during the incident. We’re building GridSEAL to help with that record, and a person still signs each report.
