Not every data centre needs 100 MW. Edge nodes, colocation halls and AI inference racks fit inside existing high-power factories. Here is the amps-to-MW maths, the TNB Green Lane reality, and the 50 units at 3000A and above currently listed.
Malaysia's data centre story is dominated by hyperscale headlines, and those numbers distort what most operators actually need. Johor's pipeline stands at roughly 4.0 GW of upcoming capacity, with about 700 MW under construction and 3.3 GW planned or announced, and STACK Infrastructure is building a 220 MW campus in Johor Bahru with first delivery in Q4 2026, powered off TNB's 275kV infrastructure with an on-site substation.
None of that is a shed conversation. A 220 MW campus is a land, grid and substation project measured in years.
But a very large share of real demand is not that. It is:
All of those fit inside an existing industrial building, provided the power is already there. That is the market this article is about, and it is the one where a property agent can genuinely move faster than a grid application.
Malaysian industrial supply is 415V three-phase. At power factor 0.9, usable load is roughly 0.65 kW per amp:
| 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 |
Then apply PUE. If the facility runs at PUE 1.5, IT load is total load divided by 1.5:
| TNB intake | Total load | IT load at PUE 1.5 | IT load at PUE 1.3 |
|---|---|---|---|
| 2,000A | ~1.29 MW | ~0.86 MW | ~1.00 MW |
| 3,000A | ~1.94 MW | ~1.29 MW | ~1.49 MW |
| 6,000A | ~3.88 MW | ~2.59 MW | ~2.99 MW |
| 8,000A | ~5.18 MW | ~3.45 MW | ~3.98 MW |
Put concretely: a 6,000A unit supports roughly 2.6 MW of IT load at PUE 1.5. At an average 8 kW per rack that is around 320 racks, and at 15 kW per rack for denser AI workloads, about 170 racks. That is a serious regional facility, and it exists today as rentable industrial stock.
FactoryHub records a confirmed amperage figure on 929 active listings. Filtering by power band:
| Intake band | For rent | For sale | Total |
|---|---|---|---|
| 3,000A and above | 32 | 18 | 50 |
| 2,000 to 2,999A | 15 | 23 | 38 |
| 1,500 to 1,999A | 8 | 4 | 12 |
| 1,000 to 1,499A | 171 | 89 | 260 |
| 1,000A and above | 226 | 134 | 360 |
By area, at 1,000A and above:
| Area | For rent (1000A+) | For sale (1000A+) | Highest intake seen | Avg rent psf | Avg sale psf |
|---|---|---|---|---|---|
| Port Klang | 152 | 61 | 8,000A | RM1.77 | RM420 |
| Kapar | 11 | 16 | 3,500A | RM1.81 | RM416 |
| Shah Alam | 15 | 8 | 6,000A | RM2.06 | RM498 |
| Telok Panglima Garang | 9 | 15 | 5,800A | RM1.70 | RM346 |
| Bandar Puteri Klang | 12 | - | 6,000A | RM3.46 | - |
| Subang | 10 | - | 1,600A | RM2.15 | - |
| Banting | - | 4 | 2,000A | - | RM290 |
| Jenjarom | - | 4 | 1,000A | - | RM372 |
At 2,000A and above on the rental side, the concentration is stark: Port Klang holds 40 of 47 units, averaging RM1.71 psf per month, with Shah Alam (3 units, RM2.10 psf), Kapar (2), Bandar Puteri Klang (1, at 6,000A) and Semenyih (1) making up the rest. If your brief is 2 MW or more in an existing building, Port Klang is where the search starts whether you like the location or not.

Power gets you on the shortlist. These decide whether the building actually works:
If the building's existing intake is not enough, the upgrade path runs through TNB. Two things are worth knowing.
The Green Lane Pathway exists and it works. TNB established it specifically for the data centre market, cutting connection time from the normal 36 to 48 months down to about 12 months, roughly three times faster, with a one-stop centre for data centre investors. As of March 2026, 33 projects had been delivered under the framework. TNB is also running a RM43 billion grid modernisation programme geared to data centre demand growth.
But 12 months is still 12 months. If your service has to be live sooner than that, the answer is not an upgrade application, it is finding a building where the intake is already energised at the level you need. That is exactly what the 50 units at 3,000A and above are for.
Rent suits operators who want to be live fast, are proving a market, or want to keep capital in equipment rather than real estate. The constraint is lease tenor: a serious fit-out needs a lease long enough to amortise it, plus renewal options, plus a landlord who will accept structural and electrical modifications.
Buy suits operators committing to a location for a decade or more, where the fit-out value would be stranded under a lease, or where you want to control expansion on adjacent land. It is also usually the answer if you need to build a substation.
Land and build is the route above roughly 10 MW, or where the shell requirements (height, structural, security perimeter, generator yard) simply are not met by existing stock. See industrial land in Selangor or ask us to run a build-to-suit brief.
We handle all three. Tell us the target IT load, the go-live date and whether you are renting or buying, and we will come back with what exists.
It depends entirely on IT load. At 415V three-phase and power factor 0.9, roughly 0.65 kW per amp, so 2,000A gives about 1.29 MW total or 0.86 MW IT load at PUE 1.5; 3,000A gives about 1.94 MW total or 1.29 MW IT load; 6,000A gives about 3.88 MW total or 2.59 MW IT load. Hyperscale campuses at 100 MW and above are land and grid projects, not factory conversions.
Yes, for edge nodes, enterprise private halls, AI inference pods, disaster recovery sites and small colocation facilities in the 0.5 to 5 MW range, provided the intake is already energised. FactoryHub currently lists 50 units at 3,000A and above (32 for rent, 18 for sale), with the largest single intake at 8,000A. Beyond amps you need to check floor loading, clear height, roof capacity for chillers, generator yard space, water and fibre routes.
TNB's Green Lane Pathway cuts data centre connection from the normal 36 to 48 months down to about 12 months, roughly three times faster, with a dedicated one-stop centre. As of March 2026, 33 projects had been delivered under the framework. If you need to be live sooner than 12 months, take a building where the supply is already energised rather than applying for an upgrade.
At 2,000A and above on the rental side, Port Klang holds 40 of the 47 available units, averaging RM1.71 psf per month, with the remainder in Shah Alam, Kapar, Bandar Puteri Klang and Semenyih. Across sale and rent at 3,000A and above, there are 50 units in total. You can filter by amperage on the search by technical specs page.
For units at 1,000A and above, average asking rent is about RM1.77 psf per month in Port Klang, RM1.81 in Kapar, RM2.06 in Shah Alam, RM2.15 in Subang and RM3.46 in Bandar Puteri Klang. At 2,000A and above the Port Klang average is RM1.71 psf. These are asking figures from live listings, not transacted rents.
Rent if speed to market matters most and you can secure a lease tenor long enough to amortise the fit-out, with a landlord who accepts structural and electrical modification. Buy if you are committing to the location long term, need to build a substation, or want to control adjacent expansion land. Above roughly 10 MW, land plus a purpose-built facility is usually the only realistic route.
Johor carries the hyperscale pipeline, roughly 4.0 GW of upcoming capacity with about 700 MW under construction, and is where the largest campuses are landing. Selangor suits latency-sensitive and enterprise facilities that need to be close to Kuala Lumpur, and a second wave of mega-campuses is breaking ground beyond Johor including at Serendah in Selangor and Springhill in Negeri Sembilan. For sub-5 MW facilities in existing buildings, Selangor has the deeper stock of high-power industrial units.
Whether you want to rent while you prove the line out, or buy and commit to a site, we handle both. FactoryHub is operated by CID Realtors Sdn Bhd, an industrial-only agency, and we co-broke across the whole market, so if the right unit is another agent's listing we will still put it in front of you.
