Factory & Warehouse for EV and Battery Operations in Malaysia 2026: Power, Floor Loading and Where to Find Them
EV and battery operations fail site selection on power, not price. Here is what amperage a battery line actually needs, how amps convert to MW, the floor loading and fire considerations, and where high-power units are listed across Selangor.

Key Takeaways
- Power is what kills EV and battery site searches, not rent. A cell finishing or formation line needs an order of magnitude more intake than the light assembly most vacant factories were built for.
- Rule of thumb at 415V three-phase, power factor 0.9: 1 amp ≈ 0.65 kW. So 1,000A ≈ 0.65 MW and 3,000A ≈ 1.94 MW.
- FactoryHub lists units at 1,000A or above across Selangor, for rent and for sale, with the highest single intake at 8,000A in Port Klang.
- Port Klang carries the deepest high-power inventory, averaging RM1.77 psf/month rent and RM420 psf sale.
- Battery storage is a compliance question, not just a shed question. SIRIM certification for battery energy storage products is expected to become fully mandatory in Malaysia in mid to late 2026, and the process includes an inspection of the Malaysian warehouse.
- Rent to prove the line, buy to scale. We handle both, and co-broke the whole market either way.
Why EV and Battery Tenants Fail Site Selection
Most industrial units in the Klang Valley were built for light assembly, storage or general manufacturing. Their TNB intake reflects that: a typical 20,000 to 40,000 sqft semi-detached factory comes with 200A to 600A. That is fine for a warehouse with some packing lines. It is nowhere near what a battery process needs.
The failure pattern is always the same. A tenant signs a lease on floor area and location, then discovers that upgrading the intake from 600A to 2,000A means a substation, a TNB application, a contribution payment and a lead time measured in quarters, not weeks. By then the rent clock has already started.
So the first question on any EV or battery brief is not "how many square feet" but "how many amps, and is that intake already energised".
What Amperage Actually Means in Megawatts
Malaysian industrial supply is 415V three-phase. At a power factor of 0.9, usable load is roughly 0.65 kW per amp. Here is the conversion buyers and tenants should have in their head:
| TNB intake (amps) | Approx. usable load | In MW | What it realistically runs |
|---|---|---|---|
| 400A | ~259 kW | ~0.26 MW | Light assembly, storage, small workshop |
| 1,000A | ~647 kW | ~0.65 MW | Standard production line, cold storage, mid-size plant |
| 1,500A | ~970 kW | ~0.97 MW | Multi-line assembly, moderate process heating |
| 2,000A | ~1,294 kW | ~1.29 MW | Battery module / pack assembly, dry room, small edge data hall |
| 3,000A | ~1,940 kW | ~1.94 MW | Cell finishing lines, formation & aging, ~1.3 MW IT load at PUE 1.5 |
| 6,000A | ~3,881 kW | ~3.88 MW | Heavy process plant, ~2.6 MW IT load at PUE 1.5 |
| 8,000A | ~5,175 kW | ~5.17 MW | Largest single intake on FactoryHub today, ~3.4 MW IT load at PUE 1.5 |
Two caveats worth stating plainly. First, an intake rating is the ceiling, not what you can draw continuously without design margin. Second, a listed amperage figure is what the current occupier has, and it may or may not survive a change of tenancy, so it always needs verification against the TNB documents before you commit.
Power Needs by Process Stage
Battery and EV work is not one load profile, it is several very different ones:
| Operation | Typical intake to look for | Notes |
|---|---|---|
| Pack and module assembly | 800A to 2,000A | Torque tools, testers, conveyors, HVAC. Often the entry point for Malaysian operations. |
| Dry room operations | 1,500A to 3,000A | Dehumidification is the load driver, and it runs continuously. |
| Formation and aging | 2,000A to 6,000A+ | Cyclers draw hard and run around the clock. Highest-load stage in the chain. |
| Electrode coating and calendering | 2,000A+ | Process heating, solvent recovery, extraction. |
| EV component machining | 1,000A to 2,500A | CNC banks, presses, compressors. |
| Battery and ESS warehousing | 400A to 1,000A | Load is climate control and charging, not process. Compliance drives the spec more than power. |
If you are landing in Malaysia for the first time, the practical sequence is usually pack assembly or warehousing first, then upstream. That matters for property strategy: the first site can be a rental, the upstream site usually should not be.
Floor Loading, Height and the Things Buyers Forget
- Floor loading. Battery racking, cyclers and electrode equipment are heavy. Ask for the design load in tonnes per m², and do not accept "heavy duty" as an answer. Retro-strengthening a slab is expensive and slow.
- Clear height. Racked ESS storage wants height. Standard older factories run 6 to 8 m; modern warehouses go 10 to 12 m and above.
- Fire compartmentation and separation distance. Lithium storage brings requirements that a general-purpose shed will not have been designed for. This is worth raising with Bomba early rather than after you sign.
- Loading configuration. Dock levellers versus grade-level access changes your entire inbound flow, and it is not cheap to add later.
- Power redundancy. Ask whether the intake is a single feed or dual, especially for formation lines where an outage mid-cycle scraps product.
Compliance: the SIRIM Point Most Property Articles Miss
Malaysia's regulatory framework for batteries tightened in 2026. MITI and SIRIM issued a guideline for certification and labelling of battery energy storage products covering lithium, lead-acid and nickel-based systems, and SIRIM certification for energy storage batteries is expected to become fully mandatory in mid to late 2026, after which uncertified products cannot clear customs.
The property-relevant part: the certification process includes a factory audit and inspection of the Malaysian warehouse, plus annual surveillance. In other words, the building you pick is inside the certification perimeter, not adjacent to it. Choosing a site that cannot pass an audit is a commercial problem, not just a facilities one.
Where the Market Is Heading
The demand side is real and it is landing in Malaysia now:
- Gigafactory Malaysia, a subsidiary of NanoMalaysia Bhd under the Ministry of Science, Technology and Innovation, began pilot EV battery production at a facility in Suria Industrial Park, Sepang, Selangor, an RM20 million project using graphene-enhanced NMC chemistry, targeting full megawatt-hour capacity by September 2026, and covering energy storage systems as well as EV batteries.
- EVE Energy's Malaysian plant started operations in February 2025, designed for 684 million cells a year across 15 production lines, with first-phase investment up to US$420 million.
- Gotion High-Tech has been in discussion with the Johor state government on an EV battery facility, and Enovix has announced plans for a US$1.2 billion battery plant in Malaysia.
Every one of those anchors pulls a supplier tail behind it: cathode and anode materials, separators, module housings, testing services, logistics. Those suppliers are exactly the tenants and buyers who need 1,000A to 3,000A units near a port, and they are the ones competing for a limited pool of stock.
What Is Actually Available Right Now
FactoryHub tracks a confirmed amperage figure on its active listings. Filtering to 1,000A and above, here is where they are:
| Area | Highest intake seen (1000A+ units) | Avg asking rent psf | Avg asking sale psf |
|---|---|---|---|
| Port Klang | 8,000A | RM1.77 | RM420 |
| Kapar | 3,500A | RM1.81 | RM416 |
| Shah Alam | 6,000A | RM2.06 | RM498 |
| Telok Panglima Garang | 5,800A | RM1.70 | RM346 |
| Bandar Puteri Klang | 6,000A | RM3.46 | - |
| Subang | 1,600A | RM2.15 | - |
| Banting | 2,000A | - | RM290 |
| Jenjarom | 1,000A | - | RM372 |
Reading it: Port Klang is the only area with real depth at this power level, which follows from its history of heavy industry and port-side infrastructure. Shah Alam commands a premium (RM2.06 psf rent, RM498 psf sale) for location and estate quality. Telok Panglima Garang and Banting are the value plays on the sale side at RM346 and RM290 psf, with intakes up to 5,800A available.

Frequently Asked Questions
How many amps does an EV battery factory need in Malaysia?
It depends on the process stage. Pack and module assembly typically needs 800A to 2,000A, dry room operations 1,500A to 3,000A, and formation and aging lines 2,000A to 6,000A or more. Battery warehousing is much lighter at 400A to 1,000A because the load is climate control rather than process. At 415V three-phase and power factor 0.9, 1,000A is roughly 0.65 MW.
How do I convert amps to kW or MW for a Malaysian factory?
At 415V three-phase with a power factor of 0.9, usable load is about 0.65 kW per amp. So 1,000A is roughly 647 kW (0.65 MW), 2,000A is roughly 1.29 MW, 3,000A is roughly 1.94 MW and 6,000A is roughly 3.88 MW. The intake rating is a ceiling, not a continuous draw figure.
Where can I find a high-power factory for EV or battery operations in Selangor?
FactoryHub lists units at 1,000A and above for rent and for sale. Port Klang has the deepest inventory, with intakes up to 8,000A, followed by Kapar, Shah Alam and Telok Panglima Garang. You can filter by amperage on the search by technical specs page, or send us your requirement.
How much does a high-power factory cost to rent or buy in Selangor?
For units at 1,000A and above, average asking rent is around RM1.77 psf per month in Port Klang, RM1.81 in Kapar, RM2.06 in Shah Alam and RM1.70 in Telok Panglima Garang. On the sale side, averages run RM290 psf in Banting, RM346 in Telok Panglima Garang, RM416 in Kapar, RM420 in Port Klang and RM498 in Shah Alam. These are asking prices from live listings, not transacted figures.
Can I upgrade the power supply in a factory I rent?
Sometimes, but treat it as a project with a lead time in quarters rather than weeks. It generally involves a TNB application, possibly a substation and a capital contribution, and the landlord's consent. If your process depends on the higher intake, it is far safer to take a unit where the supply is already energised at the level you need.
What do I need for a battery or ESS warehouse in Malaysia?
Beyond the building itself, the certification framework matters. SIRIM certification for battery energy storage products is expected to be fully mandatory from mid to late 2026, and the process includes a factory audit and inspection of the Malaysian warehouse, plus annual surveillance. Fire compartmentation, separation distances and Bomba requirements for lithium storage should be checked before you commit to a site.
Should I rent or buy for an EV or battery operation?
A common pattern is to rent for the first line while the process and volumes are being proven, then buy or build for upstream stages where the fit-out is heavy and the payback is long. We handle both, so tell us which stage you are at and we will shortlist accordingly.
