Monitoring and reporting system
The conduct of (internal) audits forms an important link in process monitoring and contributes to improved (control of) processes. These audits are the final step in the internal control cycle and help management gain insight into the operation of the internal control system during a particular period. TenneT works according to a three‑year audit cycle. The Board of Management and the Supervisory Board are informed annually about the results of the internal audits.
Assurance statements and certificates
Supplementary to the planning and control cycle, the Audit Department examines the internal controls for a number of critical business processes at TenneT and/or its subsidiaries. Some of these business processes are certified by our external auditor. The conclusions are set down in assurance statements for the relevant internal controls. In addition, some processes at TenneT are certified by external parties.
TenneT holds the following assurance statements and certificates:
- Assurance statement regarding the internal control of the processes for issuing and monitoring of certificates for electricity generated in an environmentally friendly manner (CertiQ)
- Assurance statement regarding the internal control of the payment process
- SCC certificate (Safety, Health and Environment Checklist for Contractors)
- ISO certificate for the Transmission Operations business unit, stating that the BU meets the ISO 9001 requirements for the construction, management and maintenance of the Dutch high‑voltage grid
