The following enforcement directive was issued in December 2025.
The functionality of the Hardened Water System is dependent on the successful implementation of both the Hardened Water Supply (Modification 12008) and Hardened Water Connection points (Modification 12004) modifications. Eskom failed to complete the online scope of the EERI Modification 12004, “Hardened Water Connection Points” by 31 October 2025 as was committed in the LTO safety case resulting in a non-compliance authorisation condition.
The NNR had subsequently issued Eskom with an enforcement notice and instructed Eskom to investigate the cause/s that have led to the noncompliance, report back to the NNR and to derive measures and take appropriate actions to prevent further delays. There are no safety implications to the plant due to the delay with the implementation of the safety improvement modification.
