Feasibility Evaluation

BESS Feasibility & Project Development Support

Early-stage engineering clarity is critical to BESS project success. ENERZIX provides preliminary sizing, technology evaluation, grid connection review, and electrical concept design to anchor sound investment decisions.

Decision to Proceed

Detailed BESS Engineering & Design Review

We provide detailed BESS engineering review and optimization including:

  • AC/DC architecture and inverter configuration
  • Battery technology selection and string sizing
  • MV/HV interconnection and transformer design
  • Protection coordination and grounding studies
  • EMS interface and control system integration

Our independent review enhances technical robustness and reduces execution risk.

Owner's Engineering

Owner's Engineering & Technical Oversight

We provide independent Owner's Engineering services for utility-scale BESS projects, protecting client interests during tendering, design, and construction, including:

  • Technical specification and employer's requirement preparation
  • EPC bid evaluation and technical compliance review
  • Detailed design review and drawing approval

Our Owner's Engineering approach strengthens contractual compliance, mitigates technical risk, and ensures long-term BESS asset performance and bankability.

Project Development Support

BESS Technical Due Diligence & Lender's Engineering

We provide independent technical due diligence for project financing, acquisition, and refinancing. Our assessments cover design integrity, system performance, degradation assumptions, grid compliance, and lifecycle risk exposure.

Grid Integration

BESS Grid Integration & Power System Studies

Grid compliance is essential for utility-scale BESS. ENERZIX performs load flow studies, short circuit analysis, voltage regulation assessment, harmonic studies, and protection coordination to ensure reliable interconnection with transmission and distribution networks.
