This project provided the challenge of keeping the site fully operational throughout the project. During the HV transformer upgrades and removal of redundant MCCs, we installed temporary generators that supplied the new central MCC. This supplied the power to the full site, ensuring Scottish Water’s process was fully operational throughout the project’s duration. A hot swap from existing MCC to new MCC was required, migrating each critical circuit over one at a time, again ensuring this was commissioned and operational before moving onto the next. This process was controlled through various switching plans and electrical permits. This project included full system integration, commissioning and telemetry of the entire site.
