Ensure a Secure and Informed Investment

Acquiring a Battery Energy Storage System (BESS) project involves complex technical, financial, and operational considerations. To mitigate risks and secure a successful transaction, Sinovoltaics offers comprehensive Technical Due Diligence (TDD) services tailored for BESS project acquisitions.

Why Perform Technical Due Diligence?
Technical due diligence is critical in evaluating the feasibility, reliability, and profitability of a BESS project. Our detailed analysis helps you:

  • Assess Project Viability: Verify that the system design and components meet operational, safety, and performance requirements.
  • Identify Risks: Detect technical, compliance, and operational risks that could impact project value.
  • Validate Compliance: Ensure adherence to local and international standards, including grid interconnection, safety, and environmental regulations.
  • Maximize ROI: Confirm that the system’s performance aligns with financial projections, enabling an informed investment decision and improved energy return on investment.


Our Technical Due Diligence Process
1. Document Review:

  • Evaluation of project contracts, warranties, and technical specifications.
  • Review of permits, grid connection agreements, and regulatory compliance documentation.

2. System Design Assessment:

  • Detailed analysis of system architecture, battery sizing, and inverter configuration to identify potential risks.
  • Review of load profiles, energy management strategies, and lifecycle cost modelling.

3. Component Evaluation:

  • Inspection of key BESS components, including batteries, inverters, and control systems.
  • Validation of certifications and performance guarantees.

4. Performance and Safety Analysis:

  • Analysis of historical performance data and manufacturer test results.
  • Assessment of thermal management, fire safety systems, and failure modes.

5. Site Inspection:

  • On-site evaluation of system installation, workmanship quality, and operational readiness.
  • Verification of site conditions, including grid interconnection points and environmental factors.

6. Risk Analysis and Mitigation:

  • Identification of technical risks, including battery degradation, system downtime, and cybersecurity vulnerabilities.
  • Recommendations for corrective actions and risk mitigation measures.

7. Comprehensive Reporting:

  • Delivery of a detailed TDD report with findings, risk assessments, and actionable recommendations.
  • Executive summaries tailored for stakeholders and decision-makers.
