A new regional control room and a rebuilt 230 kV substation, cut over with the lights on across the service area.
Operators could not lose sight of the grid for a moment, so the new control room had to be fully proven before the old one went quiet. At the same time, the substation outside was rebuilt while still carrying load. Outages were short, scheduled months in advance and could be canceled if system conditions changed.
The approach.
- 01
Control room run in parallel
The new room ran alongside the old one for weeks, with operators confirming every screen and alarm matched before the switch.
- 02
Outages scripted to the minute
Each substation outage had a switching order, a timed work plan and a restoration plan agreed with system operators.
- 03
Backup work for canceled windows
Crews always had a ready list of energized-safe tasks, so a canceled outage did not mean a lost day.
- 04
Protection tested twice
Relay panels were tested in the shop and again in place before any new equipment was energized.
The outcome.
“A canceled outage is only a lost day if you planned for one outcome. We planned for both.”
