The challenge
What the client needed
Our solution

Why PEC
Why this project chose PEC
SCB audit required IEEE 1188 compliance and third-party capacity-test reports. PEC's PM contract included the deliverables the audit needed — no extra sourcing.
Outcome
What happened in production
Multiple replacement cycles delivered without interrupting DC operations. Ongoing partnership with routine PM visits.
