Let’s energize the Aderis ClearSky™ Interconnection for the first time, and walk through the commissioning process to ensure everything is working properly.

Safety First!

This procedure is written to follow the conditions set by the prior section of this manual, Pre-Energization Checks.

If you have not yet performed the Pre-Energization Checks, or have taken any actions that altered the as-left conditions of the Aderis ClearSky set forth at the completion of the Pre-Energization Checks, we strongly recommend performing the Pre-Energization Checks before proceeding.

The following steps will require authorized and qualified commission staff to CLOSE / ENERGIZE individual medium voltage phases from the interconnection. Appropriate personal protective equipment (PPE), electrically rated tools, and knowledge of the energization process are required perform the energization process.

Improper PPE, tools, and/or knowledge will result in staff being exposed to the full interconnection voltage and could result in injury and/or death.

The following steps should only be conducted by authorized and qualified commission staff.

Preparing to Energize

Prior to allowing interconnection voltage to the Aderis ClearSky or any portion of the facility’s newly installed conductors or equipment, it is strongly recommended that the following steps be taken to minimize unsafe conditions to staff and equipment:

1. All of the Aderis ClearSky’s MV Termination Cabinet and Control Cabinet doors should be closed and secured / LOTO’d
2. All pad-mounted transformers connected to the MV loop should be electrically disconnected using the oil-emerged LBOR switches
   • If LBOR switches are not present, it is recommended that all loads on the secondary side of the transformer are isolated
3. All staff should be cleared from the field, and remain outside the energized area until the Safety Officer has determined staff main re-enter the field
4. All commissioning staff and electrical support staff should conduct a safety briefing that includes:
   1. A full review the energization procedure
   2. A review of the electrical isolation locations and methods in the event of abnormal operation
   3. A review of all required PPE and tools required applicable to the procedure
   4. The written assignment of procedure tasks to specific qualified staff members
   5. A written communication plan that includes who will coordinate the procedures execution and the halt-of the procedure in the event of abnormal operation
   6. A review of on-site and local emergency response resources, including: fire extinguishers, first aide kits, first responders, hospitals, police, fire, and EMS.
