Initial Legal Document Preparation:

Commencing the project necessitates the gathering of vital legal documentation. This includes acquiring notarized copies (four of each) of the land use rights certificate or a land lease agreement, the business registration, the legal representative’s ID or passport, and any environmental commitments. These documents should not exceed three months in age.

Submission of Electricity Purchase Application:

The journey begins with your application to purchase electricity, submitted to either the local Electricity Company or the Business Division of the Vietnam Electricity Group. This crucial step initiates the installation of your transformer station.

Clarification of Electricity Purchase Location & Purpose:

Essential documentation clarifying the intended location for electricity usage and its purpose is required. This encompasses residency or property ownership proof, identification of the business’s legal representative, and the business’s operational scope, detailed through registration certificates or investment permits.

Connection Application As Per Industry Standards:

This step involves submitting a detailed connection application complemented by schematic layouts of primary equipment post-connection and related technical specifications, adhering strictly to the Ministry of Industry and Trade’s guidelines.

Site Survey and Connection Negotiation:

Upon application receipt, a thorough site survey is conducted by the Power Company, followed by discussions to finalize the connection point’s location and the specific technical prerequisites.

Investment Contract Finalization & Legal Formalities:

This phase includes aligning with the National Electric Power Development Plan, securing the necessary construction permits, and orchestrating environmental safeguard measures.

Station Construction & Development:

The actual construction phase encompasses site preparation, possibly obtaining excavation permissions, sourcing the required materials and equipment, and managing the construction activities efficiently.

Final Acceptance & Power Activation:

To culminate the project, a commissioning panel is formed to oversee the final acceptance tests, leading to the official power activation conducted alongside the Power Company’s representatives.
