New grid connection & power supply
We work with investors from the project planning stage: calculating load, choosing the optimal connection, preparing documents and energizing on time for factory start-up.
Overview
For companies new to Du Long Industrial Park, getting the capacity and connection right from the start avoids over-investment in substations and shortens the time to start operations.
Our engineers provide free load assessment based on your equipment list, production plan and expansion roadmap, then guide you through the documents and the connection agreement.
Scope of service
- Load calculation and voltage level selection
- Site survey and proposal of the connection point to the park network
- Connection agreement and technical solution
- Guidance and review of the power supply application
- Inspection and acceptance of the customer's electrical works before energization
- Metering installation and energization
