Lessons Learned
What helped
Controls retrofits are a good margin lane and pull through outage work; the commissioning checklist kept us out of rework.
Client feedback
Bayou's hyperscale offtaker cared most about uptime risk during cutover — zero unplanned trips landed us the follow-on.
Assumptions / what to do differently
On behind-the-meter data-center cogen, plan the controls cutover around the offtaker's uptime windows, not just the plant's.
