1,000A · 3,000A · 4,000A screening
Find a factory around the real electrical load—not an advertised Amp figure. Compare existing supply, upgrade feasibility, cost responsibility and energisation timing before committing to a lease.
First principle
Supply voltage, transformer rating, maximum demand, motor starts, power quality, distribution and operating pattern must be assessed together.
Separate an active supply from an approved upgrade, proposed capacity or an owner's preliminary statement.
Calculate connected load, simultaneous demand, motor starting behaviour, process utilities and expansion allowance.
Confirm design, approvals, equipment, construction, testing and energisation milestones before the lease becomes unconditional.
Electrical capacity, cost and timing must be confirmed by the owner, utility provider and appointed qualified professionals. Property marketing information is not engineering approval.
Technical due diligence
Resolve these points before equipment arrives or the production launch depends on the proposed power capacity.
Requirement bands
These bands do not establish usable capacity. The correct requirement must come from the equipment and operating load.
Potentially relevant for substantial manufacturing operations, subject to voltage, maximum demand, load profile and internal distribution.
Often requires a verified upgrade route, technical consultants, utility coordination and a lease structure that protects the delivery programme.
May narrow the ready-factory market and make upgrade, Build-to-Suit or a different site more practical than a standard rental search.
Project-specific reference
The figures below came from one specific property evaluation. They are not general TNB tariffs, guaranteed construction budgets or standard lead times for other Johor factories. View the current 96,500 sqft I-Tech Valley reference or review a Pasir Gudang factory with a stated 3,000 Amp supply →
Reconfirm scope, validity, approvals, deposits, payment schedule, energisation date and tenancy structure before relying on this scenario.
Check the 3,000A scenario→The higher target should be justified by the actual load and expansion plan. An oversized request can add cost and delay without solving building-fit issues.
Check the 4,000A scenario→Decision routes
The best route balances building fit, electrical delivery, lease term, capital exposure and production timing.
Prioritise a verified existing supply when speed matters, while still checking the internal system and actual maximum demand.
Use a clear technical scope and commercial agreement covering cost, ownership, programme, deposits and delay consequences.
Plan the substation, distribution and production layout together when ready factories cannot meet the combined requirement.
Assess phased lines, operating shifts, motor-start strategy or equipment selection with qualified engineers when operationally feasible.
High-power factory FAQ
All capacities, costs and programmes require property-specific technical and utility confirmation.
It depends on supply voltage, equipment ratings, motor starting loads, simultaneous demand, process utilities and expansion. An Amp figure alone is not sufficient to confirm operating capacity.
The timeline varies by site, available network capacity, design, approvals, equipment procurement and construction. The I-Tech Valley reference above evaluated approximately nine to twelve months, but this is not a general Johor standard.
Responsibility is a commercial negotiation. The owner may fund it, the tenant may pay directly, or cost may be recovered through rent and a longer lease. The scope, payment, ownership and delay risk should be written into the agreement.
No. Confirm whether the figure is existing, approved, proposed or only technically possible, and verify the transformer, switchgear, cabling, protection, energisation status and utility documentation.
