KEY POINTS

  • Keep BOI conditions, utility requirements and factory obligations distinct.
  • Name the responsible designer and the standards applicable to the project.
  • Agree the handover and inspection records before work starts.

For a BOI-promoted factory, electrical work sits alongside investment-promotion conditions, factory requirements and electricity-supply arrangements. A practical plan identifies each requirement, its responsible party and the evidence needed to close it.

1. Read the promotion certificate and project conditions

The BOI’s post-promotion guidance covers operating approval and documents from other authorities, including relevant factory licences. Treat the promotion certificate as one part of the project record. It does not, by itself, establish approval of the electrical design or readiness to energise.

Create a requirements register with the source document, action, owner and due date. Refer questions about a condition to the office responsible for that condition.

2. Confirm the supply and connection arrangement

Identify the electricity provider and any industrial-estate or landlord interface. Confirm current capacity, proposed additional demand and the documents required for the requested service. Use the MEA and PEA planning guide for an initial check, then obtain the site’s current application requirements.

3. Define the design basis

Give the responsible designer the equipment schedule, operating patterns, future expansion assumptions and site restrictions. Ask the design team to identify the applicable standards and editions, utility requirements and client specifications. Resolve conflicting requirements before equipment is ordered.

Confirm who prepares, checks and signs each design document, including the applicable professional licence and scope of responsibility. Avoid assuming one licence level or one standards list suits every project.

4. Agree a usable document package

Depending on the work, the package may include:

  • Current single-line diagrams and coordinated installation layouts.
  • Load, cable and distribution-board schedules.
  • The calculations and equipment specifications supporting the design.
  • Work methods, shutdown plans and a defined testing schedule.
  • Final drawings, test results, manuals and an outstanding-item register.

State the required items in the contract. These are documents to agree for the work, not a universal BOI submission checklist.

5. Plan inspections and ongoing records

The Ministry of Industry’s factory electrical-safety regulation addresses inspection, safety certification and factory records. Confirm how the applicable inspection and reporting requirements will be met, who is eligible to carry them out and which documents the operator must retain.

Build maintenance access and the closure of test findings into the handover plan. The production team should know what remains outstanding before a system is accepted for use.

Questions for the first project meeting

Does BOI status guarantee a faster electricity connection?

Do not plan around an assumed fast track. Ask the relevant offices which arrangements apply and confirm the dependencies and dates for this project.

Can the contractor manage every approval?

Agree the scope explicitly. The owner, designer, contractor, equipment supplier and authorities have different responsibilities; appoint a coordinator without confusing those roles.

What should we send ETES first?

Share the facility location, planned equipment, available drawings and proposed programme. ETES can discuss the industrial installation and maintenance work that fits the project.
