Active Effluent Treatment Plant SCADA Upgrade

The NRS Hunterston A Site is weak in areas around our Operational Technology, and requires the support ensure our facilities are maintained and available for their operational requirement.

The SCADA allows the Remote monitoring of the AETP tank levels and RDT tanks levels within the overarching Active Effluent Treatment Facility. The SCADA is an ageing asset that has been periodically failing. The System is at the stage of poor reliability, after any planned electrical switching works, we have multiple failures on re-start and the system remains unavailable for a period of time.

The scope includes an upgrade to the SCADA to a modern equivalent.
