Commissioning & Grid Approvals
Commissioning, Testing & Grid Approval
Value Proposition
EQ Engineering ensures that every system is tested, verified, and commissioned in line with design intent, regulatory requirements, and grid conditions.
Our commissioning approach goes beyond basic energisation — it focuses on performance validation, protection verification, and approval readiness, ensuring systems are fully compliant and operational without post-COD surprises.
This stage is critical in the Indian market, where incomplete testing or documentation often leads to DISCOM delays, performance gaps, and compliance risks.
Deliverables
Key Deliverables
- Pre-Commissioning Verification
Continuity checks, polarity testing, insulation resistance testing, and system readiness validation.
- Protection & Control System Testing
Verification of protection settings, relay coordination, and fault response behaviour.
- Grid Synchronisation & Interfacing
System integration with DISCOM grid, synchronisation checks, and operational validation.
- Inverter & BESS Functional Testing
Performance verification of inverters, batteries, and control systems under real conditions.
- Performance Validation & Baseline Setting
PR validation, generation benchmarking, and initial performance recording.
- Commissioning Documentation & Handover
Test reports, certificates, and submission-ready documentation for approvals and audits.
Continuity, polarity and insulation testing to verify installation integrity before energisation.
Validation of protection settings, relay coordination and system fault response behaviour.
DISCOM grid interfacing, synchronisation checks and operational stability verification.
PR verification, baseline performance recording and complete commissioning documentation.
Grid Approval Delays (DISCOM)
Incomplete testing or documentation leading to approval hold-ups.
Incorrect Protection Settings
Systems operating without verified protection coordination.
Underperformance at COD
Systems not delivering expected output due to improper commissioning.
Incomplete Testing Record
Missing documentation affecting compliance and future audits.
Grid Instability & Site Conditions
Variability in grid behaviour impacting synchronisation and performance.
Unverified System Integration
Poor coordination between installed components affecting reliability.
Engineer-Led Commissioning Process
Commissioning executed and verified by engineering teams, not just installers.
Approval-Ready Documentation
Structured documentation aligned with DISCOM and regulatory expectations.
Protection & Performance Validation Focus
Systems tested for real operating conditions, not just energisation.
Zero Ambiguity at Handover
Complete clarity on system performance, compliance, and operation.
Reduced Post-COD Issues
Early identification and resolution of faults before system handover.
Grid-Ready Integration Approach
Systems prepared for stable operation within Indian grid conditions.
