Objective
Aurora Energy Services supported Wanzek at the Whistling Duck site in Williston, Florida, delivering the cold commissioning of 12 × Sungrow SG4400 inverters across Circuits 1A and 1B. The work scope, completed between August 3–6, encompassed full mechanical, electrical, and visual verification of inverter systems, auxiliary cabinets, and MV transformers. The project established a safe, fault-free baseline for subsequent hot commissioning and long-term operational reliability.
Challenges
- Extended site orientation requirements before access.
- High ambient temperatures impacting working conditions.
Value to Client
Aurora provided measurable value by ensuring all 12 inverters were fully “Ready-for-Hot-CX” with no outstanding safety holds.
- Thorough Pre-Energization Verification – Comprehensive checks eliminated rework risks and provided a clean punch-list, saving time during hot commissioning
- Risk Mitigation & Handoff – Verified all LOTO points, grounding plans, and interlocks to de-risk first energization, typically saving 1–2 shifts per inverter.
- Expert Knowledge Transfer – Joint walk-downs with O&M staff provided clear expectations for hot commissioning and future operations.
Cold commissioning created a fault-free, fully documented foundation, enabling hot CX to proceed safely, quickly, and predictably—protecting both schedule and revenue for the client.
