IV. Warranty and Customer Support:

A year-long warranty is provided alongside a robust customer support system, ensuring reliable and efficient energy solutions.

V. Legal and Regulatory Compliance:

For the successful construction of a transformer station in Vietnam, adherence to specific regulatory frameworks and procedural steps is crucial. Below is an outlined guide highlighting the essential documentation and preparatory measures necessary:

Legal Documentation and Initial Preparations: Initially, it’s required to compile and notarize essential legal documents, including the land use right certificate or a land lease agreement, the business license, and the legal representative’s ID card or passport. Additionally, an environmental protection pledge may be needed, with all documents notarized and no older than three months.

Application for Electricity Purchase: The foundational step towards establishing a transformer station involves submitting an application for electricity purchase. This can be directed to the local Electricity Company or the Vietnam Electricity Group’s Business Department.

Identifying the Site and Purpose for Electricity Usage: It is essential to furnish a copy of documents validating the location for electricity purchase – this could range from a permanent residence book to a house ownership certificate, among others. Furthermore, the legal representative’s ID or passport, alongside documentation like a business registration certificate or investment license, delineates the intended use of electricity at the proposed site for the transformer station.

Connection Application as per Industry and Trade Ministry Guidelines: This step encompasses submitting a connection application, complete with schematic layouts of primary equipment post-connection point and corresponding technical documentation.

Survey and Agreement on Connection: Following application submission, the Electricity Company undertakes a survey and dialogues on the technical specifications and connection point location.

Investment Contract and Legal Formalities: This encompasses agreements aligning with the Electric Power Development Planning, securing construction permits, and devising environmental protection strategies.

Construction and Station Building: This phase includes clearing the land, applying for excavation permits (if required), procuring necessary materials and equipment, and orchestrating the construction activities.

Commissioning and Energization: With construction completion, the formation of a commissioning board is vital to oversee acceptance tests and facilitate energization, coordinated with the Electricity Company.

This structured approach ensures compliance with legal and procedural requirements, laying a solid foundation for the construction of a 630kVA transformer station in Vietnam, guaranteeing operational success and regulatory conformity.
