Battery Energy Storage System (BESS) Factory Audit

To achieve World-Class status, a factory must meet numerous requirements related to product quality, reliability, and compliance with various technology, safety, and environmental standards. Each project is unique and requires dedicated resources to ensure your project fulfills its intended outcome. Our community safety, your return on investment, and grid reliability depend on our dedication.

A factory qualification audit provides comprehensive insight, with our IRCA accredited and BESS specialized auditors conducting thorough technical due diligence on prospective suppliers to prevent costly mistakes.

The process starts with you. Our experts will speak with you directly to identify specific concerns and region-specific policies that should be directly focused on during our inspection process. We will discuss which audits are best suited to ensure your project’s success. Then our audit team will assess the factory and production line in detail and identify any issues that could influence your order. Our team uses a comprehensive scorecard system that assesses every element according to its quality and technical importance. This will allow you to directly compare the facilities you are evaluating for your project. Our robust audit report is accepted by leading insurance companies, financiers, and IPPs. We provide you with the tools to make well-informed decisions.
