NGIS Accounting Technician

The PV / BESS HMI Operator / Attendant will operate and maintain a 3MW utility-scale solar Photovoltaic (PV) system and a 1MW Battery Energy Storage System (BESS) to ensure safe, reliable, and efficient electrical power distribution on the island of Diego Garcia. Key responsibilities include:

PV System Operations

• Operate the PV plant controls and monitoring system to efficiently produce electrical power.
• Utilize the PV Human Machine Interface (HMI) to collect operating data and maintain optimal plant performance.
• Coordinate PV plant output to ensure compliance with voltage tolerances.
• Ensure the PV system disengages from the grid and maintains system voltage within specified tolerances during dynamic or transient conditions.

BESS Operations

• Operate the BESS controls and monitoring system to regulate electrical power output and battery charging retention.
• Utilize the BESS HMI to collect operating data and maintain efficient electricity storage operations.
• Coordinate BESS plant output to maintain voltage tolerances and support grid stability.
• Ensure the BESS disengages from the grid and maintains system voltage within specified tolerances during dynamic or transient conditions.
• Optimize BESS output and input to reduce thermal generation ramping and ensure PV smoothing functions.

General Operations

• Perform "watchstanding" or attendance duties to oversee the safe and efficient operation of the PV and BESS systems.
• Provide operational oversight to ensure reliable electric power production that meets the system's demands.
• Monitor plant controls and make adjustments to maintain continuous and efficient electrical power distribution.
• Work closely with technical teams to ensure both systems operate optimally under varying conditions and provide operational feedback for system improvements.

Minimum Requirements

• A high school diploma or equivalent.
• Certification as a solar and BESS operator, with the preferred certification being the North American Board of Certified Energy Practitioners (NABCEP) Board Certification for PV or an equivalent certification. (Certification copies must be provided as per contract requirements.)
• 1-3 years of experience operating and maintaining utility-scale PV and BESS platforms or comparable systems.
• Proficient in using Human Machine Interface (HMI) systems for monitoring and managing PV and BESS operations.
• Highly organized with strong attention to detail and the ability to troubleshoot and resolve operational issues in a timely manner.
• Previous work experience in an austere OCONUS (Outside the Continental United States) environment with a multi-national workforce.
• Excellent organizational, time management, and customer service skills.
