Case Study:

UK energy supplier: Converting from Siemens S5 to S7 in a week


Share via:

A major UK energy supplier was looking to upgrade the control system of a power station water treatment plant. The energy supplier had experienced a number of unplanned shutdowns that were in turn negatively impacting the power station’s operation. These shutdowns were due to problems with legacy Siemens S5 hardware used in the process, particularly the difficulty in obtaining needed spare parts.

A control system upgrade was needed, but to reduce the impact on operations, the enegery supplier needed the Cougar Automation team to have it completed during a scheduled one-week maintenance period.
