PKI certificates

All digital information exchanged between TenneT and other electricity market participants is secured by public key infrastructure (PKI) certificates.

Please note: for regular process, please see below.

Renewal PKI certificates 2017

The certificates that are provided by Digidentity, have a validity of three years. Since these certificates will expire for multiple parties in the upcoming period, TenneT has started a project to coordinate the prolonging of the certificates for the market parties.

For this reason also additional information with respect to this project will be made available on this website.

With additional questions on the renewal process, you can contact the project team directly by making use of the following phone number: +31(0)26 – 373 3535 or CPS_Certificaatverlenging2017(at)tennet.eu.

Safe data

These PKI certificates verify and authenticate the identity of users in online networks and keep the data safe. Market parties that are recognised by TenneT must use PKI certificates for online communication. The PKI certificates are provided to new and existing parties by Digidentity, the certificate service provider that created the authentication system used by the Dutch government. 

For more information about TenneT’s use of Digidentity and PKI certificates, or to apply for accreditation, see cpscertificatenaanvraag.tennet.eu or contact our Customer Care Centre with specific questions on tennetccc(at)tennet.eu.
