We provided the complete supply, installation, and commissioning of a DC backup battery bank system designed to ensure uninterrupted power for critical control, protection, and automation systems in a high-voltage (HV/EHV) substation environment.

The scope of work included:

• Installation of stationary industrial-grade batteries (110V/220V DC configuration) with robust racking systems for safety and maintenance access.

• Proper interconnection using insulated terminals and busbars to ensure secure polarity alignment and long-term operational reliability.

• Integration with DC distribution panels, battery chargers, and monitoring systems.

• Compliance with international electrical and safety standards (e.g., IEC, IEEE) for substation auxiliary systems.

• Functional testing and commissioning to validate autonomy, charging efficiency, and system readiness during mains failure.

This system supports mission-critical operations such as:

• Circuit breaker trip/close operations

• Protection relay powering

• SCADA/RTU communication equipment

• Emergency lighting and alarms

Our solution enhances substation reliability by providing a stable and redundant DC power source during any AC supply interruption.
