Manufacturer Prequalification
To ensure a secure and reliable electricity network, only manufacturers approved by EWA are permitted to supply materials and equipment. EWA evaluates each manufacturer’s technical and financial capabilities, and assesses their materials and equipment to ensure compliance with EWA specifications and relevant international standards for quality and performance.
Service Information
To initiate the process, suppliers are invited to submit a prequalification application, enabling EWA’s team to assess the manufacturers’ technical expertise, financial stability, and compliance with international standards. This ensures only qualified and reliable manufacturers are approved to supply materials to the distribution network— thereby supporting quality, safety, and long-term supply chain resilience.
