Will Johor’s data center boom last?

Get all the data you need about the real estate market in Johor

How big is Johor’s data center market now?

Johor is already one of Asia’s biggest data center markets today, so we are well past the stage where this boom can be dismissed as a collection of future projects.

Cushman & Wakefield counted 1,110MW of operational IT capacity in Johor in its latest Asia-Pacific update. That was up 24% in only six months. Another 602MW was under construction, while 2,486MW remained in planning.

Put those numbers together and Johor has slightly more than 4.1GW of operational and future capacity. Cushman & Wakefield now ranks it as the largest Asia-Pacific market by combined existing and future capacity.

The speed of the change is what really stands out. At the end of 2024, Knight Frank estimated Johor had roughly 370MW operating. Different research firms do not classify projects in exactly the same way, so the two figures should not be treated as a perfect like-for-like series. Even with that caveat, Johor has clearly moved from a few hundred megawatts to a market measured in gigawatts within a remarkably short period.

There is still a huge gap between what exists and what developers hope to build, though. Roughly three quarters of Johor's 4.1GW-plus potential capacity is either being built or remains on paper. That gap will shape almost every question in this article.

Johor data center capacity	Latest level	Six-month change	What we can actually conclude
Operational	1,110MW	+24%	Johor is already a large live market
Under construction	602MW	+91%	Development is still accelerating
Planned	2,486MW	+19%	Most future capacity has not been built
Development pipeline	3,088MW	+28%	Johor still has years of potential expansion
Operational + future	>4.1GW	—	Johor now leads APAC on combined capacity

Is Johor’s data center boom still growing this fast?

Yes. Johor’s data center boom is still growing extremely fast, and the latest construction numbers are stronger than the announcement headlines.

Capacity under construction rose from roughly 315MW to 602MW in six months, an increase of 91%. Operational capacity also rose 24% over the same period.

Projects are moving from planning into construction while completed facilities are simultaneously coming online. We are seeing actual physical delivery rather than a pipeline that keeps getting larger because developers announce new campuses faster than they build old ones.

Malaysia as a whole reinforces the picture. MIDA's latest investment figures show RM95.8 billion of approved data center and cloud-computing investment in the first half of 2026. That represented close to 44% of every ringgit of investment approved in Malaysia during the period.

Doubling construction capacity every six months obviously cannot continue for long. Johor can keep adding data centers for years while growing much more slowly than it has lately.

The boom is still accelerating in absolute development today, but we are probably close to the end of the period when percentage growth can look this spectacular.

Are companies actually filling Johor’s new data centers?

Yes. Demand for Johor data center capacity currently looks strong enough to absorb the new supply that has reached the market.

That is one of the most reassuring findings in the whole analysis. A construction boom becomes worrying when new buildings open faster than customers occupy them. Johor has so far shown the opposite pattern.

Earlier Knight Frank research recorded around 260MW of Johor take-up in the first half of 2025 alone. Social-media workloads accounted for 61% of that activity, with AI and hyperscale demand making up much of the remainder.

Since then, hundreds of additional megawatts have moved into operation. Yet the latest market data still shows extremely tight availability. Johor colocation vacancy is around 0.7%.

We have to use that figure correctly. Colocation vacancy does not tell us how busy every privately operated hyperscale building is, and a campus can have completed shell capacity that has not yet reached full IT utilisation. Even so, a market adding supply this quickly would normally show obvious vacancy pressure if customer demand were weak.

We do not see that pressure today.

Demand measure	Recent evidence	What it suggests
Johor take-up in H1 2025	~260MW	Customers contracted a large amount of capacity
Social-media share	61%	Very large digital platforms are driving demand
Operational capacity growth	+24% in six months	Supply kept arriving
Colocation vacancy	~0.7%	Available commercial capacity remains extremely tight

How much of Johor’s huge data center pipeline will actually get built?

A large part of Johor’s pipeline should get built, but anyone treating the full 3GW-plus development pipeline as inevitable is getting ahead of the evidence.

The split tells us why. Around 602MW is currently under construction, while approximately 2,486MW is still planned. So about four out of every five megawatts in the development pipeline have not reached construction.

Planned capacity can sit there for years. Developers often secure more land and power potential than they initially need because hyperscale campuses are built in phases. Customers may appear later, grid connections can move, and expansion phases can be postponed without cancelling the whole campus.

Look at the projects already announced. AirTrunk's JHB1 and JHB2 campuses have combined potential above 420MW. YTL's Green Data Center Park has a stated long-term capacity of up to 500MW. TM Nxera has discussed more than 200MW in Iskandar Puteri. ST Telemedia Global Data Centres has a Johor campus that can eventually reach 120MW.

Those numbers describe what the sites could ultimately support. They do not mean all of that capacity will switch on at once.

There are good reasons to take the pipeline seriously, though. AirTrunk has already expanded from one major Johor campus into another. Vantage bought Yondr's large Johor platform instead of allowing that capacity to disappear when Yondr shifted its strategic focus elsewhere. DayOne has backed its Malaysian expansion with a renewable-energy framework covering up to 500MW over 21 years.

These are companies making long-term infrastructure commitments, which makes the pipeline much more credible than a collection of undeveloped land options.

Our working assumption is simple: the construction pipeline is highly credible, while the much larger planned pipeline deserves a discount. Johor does not need every planned project to materialise for the market to keep growing strongly.

Is Johor still just Singapore’s cheaper data center backyard?

No. Johor still depends heavily on its relationship with Singapore, but the market has become too large and too sophisticated to describe it as simple overflow.

Singapore's earlier restrictions on new data center development clearly helped start the rush across the border. Johor offered cheap land, relatively low operating costs and one-to-two-millisecond connectivity back to Singapore. For hyperscalers that wanted to remain close to the regional hub while deploying much larger campuses, the logic was unusually strong.

That advantage has not disappeared.

TM and Singtel's Nxera project is explicitly designed around the Singapore-Malaysia digital corridor. STT GDC is connecting its Johor facilities into its Singapore ecosystem. The Johor-Singapore Special Economic Zone is also pushing digital investment as one of its target industries.

At the same time, Johor is now attracting infrastructure designed specifically for AI and high-density computing. AirTrunk has deployed direct-to-chip liquid cooling. TM Nxera is targeting GPU-intensive workloads. Large renewable-energy contracts are being signed around Johor campuses.

Those are signs of a market developing its own infrastructure specialisation.

Singapore remains the commercial and connectivity anchor for a lot of this demand. Johor has become an essential second half of that regional setup rather than a temporary place to send whatever Singapore cannot accommodate.

Could Singapore start taking Johor’s data center demand back?

Singapore will take some demand that might previously have gone straight to Johor, but its controlled reopening is far too small to reverse Johor’s growth on its own.

Singapore has started releasing new data center capacity again. Its Green Data Centre Roadmap initially targeted at least 300MW of additional capacity, and authorities later opened another allocation process covering at least 200MW.

A few years ago, the easiest version of the Johor thesis was that Singapore had effectively stopped building, leaving large cloud and hyperscale deployments with limited choices nearby. That explanation is now outdated.

Singapore still has serious physical constraints. Land is scarce, electricity demand is tightly managed and new data center capacity is awarded selectively. A few hundred additional megawatts can absorb premium workloads, but it does not recreate the kind of space available across large Johor campuses.

Johor also has more than 600MW being built right now, before we even count its planned pipeline.

The relationship will probably settle into a split model. Singapore remains attractive for workloads that value dense connectivity, financial infrastructure and the city-state's business ecosystem. Johor handles a much larger share of the land-hungry and power-hungry compute behind those services.

Singapore's return makes Johor compete harder. It does not erase Johor's reason for existing.

Is AI demand strong enough to keep Johor’s data centers busy?

AI demand is strong enough to support another major wave of Johor data center growth, although we would be very cautious about using AI forecasts to justify every planned campus.

The freshest national investment numbers are extraordinary. MIDA says Malaysia approved RM95.8 billion of data center and cloud investment in the first half of 2026. Information and communications investment reached RM103.3 billion, meaning data centers and cloud accounted for almost all of that category.

This demand also sits inside a much larger Asian build-out. Cushman & Wakefield found that Asia-Pacific's data center development pipeline grew by 7.1GW in six months to roughly 26.5GW. Nearly half of the region's capacity under construction is now in Southeast Asia.

Johor is riding two trends at once: regional cloud expansion and the much more compute-intensive AI investment cycle.

The hardware being installed gives us another clue. Operators are preparing for higher rack densities, GPU clusters and liquid cooling rather than building only conventional enterprise server rooms. These designs are expensive, so developers would have little reason to deploy them everywhere without real customer conversations behind the scenes.

Where we become less confident is several years out.

AI hardware is improving quickly. Training techniques change. Inference keeps getting cheaper. Hyperscalers can shift workloads between countries. A market that appears chronically short of GPU capacity today could eventually become much better supplied.

Johor needs AI demand to remain large. It does not need today's shortage conditions to last forever.

Can Johor’s power grid handle all these new data centers?

Johor has enough electricity generation for the immediate wave of data centers, but getting that power to the right campuses is now the biggest constraint on continued growth.

Wood Mackenzie's recent study is unusually useful here because it separates generation from grid access. Johor has roughly 6.8GW of installed generation capacity against statewide demand of around 2.6GW. Looking only at those two figures, the state appears to have plenty of spare power.

Data centers expose the weakness in that comparison.

A 100MW campus cannot simply tap into unused electricity somewhere else in Johor. It needs a very large connection at a specific location, high-voltage infrastructure, redundant supply and substations capable of supporting an almost constant load.

Wood Mackenzie says transmission and distribution capacity around the main data center clusters is already becoming the critical bottleneck. The consultancy estimates data centers currently represent roughly one quarter of Johor's end-user electricity consumption and could reach around 40% by 2035.

That would radically change the state's electricity profile.

The pressure is especially concentrated around Sedenak, Nusajaya and other large data center clusters. Several huge projects asking for power in the same area can overwhelm local grid infrastructure long before Johor runs short of electricity generation overall.

There is a longer-term generation issue as well. Around 2.1GW of coal capacity is expected to retire in the mid-2030s, according to Wood Mackenzie. Malaysia has years to replace it, but replacement generation and new transmission lines have to arrive while data center demand is still climbing.

So we would watch grid-connection dates more closely than new campus announcements from now on. Land can be bought quickly. A new transmission system cannot.

Johor power indicator	Approximate level	What we learn
Installed generation	6.8GW	Near-term generation remains adequate
State electricity demand	2.6GW	Headline supply margin still looks large
Current data center share	~24%	Data centers already use a major share of electricity
Possible 2035 share	~40%	The sector could reshape Johor's entire grid
Johor capacity being built	602MW IT	A large new electricity load is already approaching
Main near-term constraint	Grid connections	Transmission and substations are becoming decisive

Can Johor find enough clean power for all these data centers?

Johor can add far more renewable electricity than it has today, but clean power is becoming part of the competition for scarce infrastructure rather than an easy box for developers to tick.

Malaysia has opened a much clearer route for large corporate buyers through CRESS, its Corporate Renewable Energy Supply Scheme. The programme allows companies to contract renewable electricity through the grid instead of depending entirely on the existing generation mix.

By May 2026, eight major green consumers from data centers, technology and manufacturing were linked to roughly 3GW of renewable capacity under the scheme.

DayOne shows what that can look like at hyperscale. The company signed a long-term framework with TNB Renewables covering up to 500MW of renewable energy for its Malaysian data center operations.

Johor is also considering much bigger renewable infrastructure, including a proposed southern renewable-energy corridor that Wood Mackenzie says could eventually support several gigawatts of solar capacity with storage.

The difficulty is speed. A data center building can rise faster than the solar projects, batteries, substations and transmission network needed to supply it reliably.

This is already changing which projects look credible. Developers that control a site but still have vague answers on electricity will struggle more than operators that arrive with long-term power arrangements.

Clean power should support Johor's boom over the long run. In the near term, securing it may slow the queue.

Could Johor run out of water because of data centers?

Johor does face a real water problem as its data center market expands, but current facilities are using much less water than developers originally reserved.

BIMB Research found around 15 operating Johor data centers consuming approximately 18 million litres per day, compared with about 45 million litres per day initially requested. Actual consumption was only around 40% of the booked amount.

That gives Johor more breathing room than the worst headlines suggest.

The future numbers are much harder. Based on forward submissions from data center operators and broader industrial growth, Ranhill SAJ estimates Johor could need roughly 1,000 million litres per day of additional potable-water capacity by 2030.

The state is adding supply, including the 160MLD Layang 2 Phase 2 expansion and other treatment projects. Yet infrastructure on that scale takes years.

Operators are already trying to reduce their reliance on ordinary drinking water. DayOne has developed its own river-water treatment solution at Kempas, while Bridge Data Centres has worked on reclaimed-water supply.

Johor has also introduced a dedicated data center tariff of RM5.33 per cubic metre. That is a useful policy signal because it forces the industry to pay more explicitly for the resource it consumes.

We see water as a brake on poorly planned projects rather than an immediate ceiling on the whole market. Johor can still support large growth if treatment capacity, reclaimed water and lower-water cooling systems expand with it.

Johor water measure	Approximate level	What it means
Consumption by ~15 operating DCs	18MLD	Current use is still relatively modest
Water originally requested	45MLD	Operators use ~40% of booked volume
Additional potable supply estimated by 2030	~1,000MLD	Johor needs major infrastructure expansion
Layang 2 Phase 2	160MLD	Helpful, but only part of the requirement
Dedicated DC water tariff	RM5.33/m³	Water is being priced more explicitly

Is Johor starting to reject weaker data center projects?

Yes. Johor is becoming much pickier about data center approvals, and that should reduce the wildest part of the boom.

The state introduced a technical vetting process covering electricity, water, location and sustainability. Reuters previously reported that around 30% of applications had been rejected during the early phase of that screening because they did not meet the required water and energy standards.

The federal government has since tightened the process further through the Data Centre Task Force.

MIDA's latest description of the system is quite direct: projects need secured power and water, acceptable green credentials and stronger participation in Malaysia's local supply chain before they receive priority.

This tells us where Johor is in the cycle now. A place desperate for investment tends to advertise how quickly it can approve projects. Johor has enough demand today to start asking which projects deserve scarce utility capacity.

Some planned campuses will probably disappear because of that.

That would make the headline pipeline smaller without necessarily making the market weaker. Filtering out projects that have land but no believable power, water or customers is exactly what Johor needs if it wants the boom to last.

Is Johor still cheap enough for data centers?

Johor remains much cheaper and easier to scale than Singapore for very large data centers, although the spectacular bargain that attracted the first wave is gradually becoming less obvious.

Industrial land prices have already moved higher. JLL reported average Johor industrial land values around RM86 per square foot in 2025, about 8% above the previous year.

Ordinary industrial land is also a misleading benchmark once the market gets crowded. A data center operator cares about power availability, fibre routes, water, planning approval and proximity to existing infrastructure. Sites that combine all of those features are much scarcer than empty land.

Utility costs are changing as well. Data centers now pay a dedicated water tariff. Renewable-power access has a cost. Developers may have to fund more grid infrastructure, batteries or other reliability measures as power systems tighten across Asia-Pacific.

Yet Johor started with a very large advantage.

Malaysia still offers far more space than Singapore, construction costs remain competitive by Southeast Asian standards and the two markets are physically close enough to operate as one regional digital corridor for many workloads.

That is why rising Johor costs do not automatically push the industry somewhere else. Bangkok may offer another route to scale, Jakarta has enormous domestic demand and other Malaysian states are trying to attract projects, but none replicates Johor's exact combination of land and proximity to Singapore.

Johor can become significantly more expensive than it was five years ago and still make financial sense.

Is Bangkok catching Johor in the data center race?

Bangkok is growing faster than Johor right now, but Johor still has a huge head start in operating capacity.

The latest Cushman & Wakefield figures make Bangkok the competitor worth watching most closely. Bangkok had 859MW under construction, up 148% in six months. Johor had 602MW under construction, up 91%.

So Thailand is currently building more.

The installed base tells a very different story. Bangkok had only about 134MW operational, while Johor had 1,110MW. Johor therefore had more than eight times as much live capacity.

That gap brings advantages that take time to copy: experienced contractors, power infrastructure, fibre connections, established operators and customers that already understand the market.

Jakarta is another serious competitor because Indonesia provides a huge domestic digital economy. Vietnam is attracting hyperscale proposals. Sydney and Mumbai remain much larger regional markets in their own right.

Johor no longer has an empty field around it.

Still, Johor does not need to dominate every new Southeast Asian project. Its existing base plus the amount already under construction gives it enough momentum to remain a top-tier hub even if Bangkok takes a larger share of the next wave.

Market	Operational capacity	Under construction	Development pipeline	What stands out
Johor	1,110MW	602MW	3,088MW	Largest combined existing and future capacity
Bangkok	134MW	859MW	2,084MW	Construction is growing fastest
Sydney	917MW	—	2,134MW	Large established APAC hub
Mumbai	890MW	—	1,726MW	Strong domestic-demand market
Jakarta	—	395MW	1,699MW	Major Southeast Asian competitor

Is Johor getting enough jobs from all this data center investment?

Johor is attracting extraordinary amounts of capital from data centers, but the permanent job count is fairly small compared with the money and resources going into the industry.

The Johor government said 42 approved data center projects were worth RM164.45 billion and expected to create more than 6,000 quality jobs.

If we divide those headline figures mechanically, that comes to roughly RM27 million of approved investment per expected job.

We should not read too much into that exact ratio because investment and employment arrive at different stages, while construction workers, contractors and suppliers are not fully represented in permanent operating-job numbers. The scale still tells us something useful.

Data centers are incredibly capital intensive. A huge campus can contain billions of ringgit of servers, electrical equipment and cooling systems while employing a relatively small operations team once construction is finished.

Malaysia clearly knows this. Its latest approval policy gives more weight to projects that use local suppliers and contribute more to the surrounding economy.

Johor is also trying to build data center training programmes and technical skills around the industry. That is where a lot of the longer-term economic upside will be decided.

If Johor ends up supplying land, electricity and water while most high-value cloud and AI activity remains somewhere else, the public argument for endless expansion gets weaker. If the data centers pull engineering, AI, cloud services, renewable-energy investment and local suppliers into Johor with them, the payoff becomes much easier to defend.

For now, that second-order ecosystem is growing, but it is much less proven than the data center construction boom itself.

What could actually stop Johor’s data center boom?

The most credible way Johor’s data center boom ends badly is through several problems hitting at once: slower customer demand, too much planned supply, delayed power connections and tougher resource rules.

Demand is the first thing we would watch. Today's vacancy is extremely low, so Johor has a substantial cushion. If vacancy begins rising while hundreds of megawatts continue to open, that would tell us supply has finally caught up.

The planned pipeline is the second risk. More than 2.4GW has yet to reach construction. Those projects depend on customers, financing, approvals and utilities that may never arrive in the form originally announced.

Power is probably the most immediate physical constraint. Wood Mackenzie already sees transmission and distribution as the bottleneck. A sustained run of delayed grid connections would quickly change development economics.

Water could create the same problem later in the decade if new treatment capacity fails to keep pace with actual consumption.

Competition adds another layer. Singapore is allocating capacity again, Bangkok is building aggressively and other Southeast Asian markets want a bigger share of hyperscale investment.

Finally, AI itself could surprise on the downside. Much more efficient chips or slower hyperscaler capital spending would reduce the number of megawatts needed for the same amount of computing.

None of those pressures is currently severe enough to break the Johor growth story. They do make the next few years much harder than the last few.

Will Johor’s data center boom actually last?

Yes. Johor’s data center boom should last for years, but the frantic land-grab phase is already giving way to a slower fight over power, water and real customers.

The case for continued growth is unusually strong.

Johor already has more than a gigawatt of operational capacity. New facilities are still being absorbed. Construction activity remains exceptionally high. Malaysia is approving tens of billions of ringgit of new data center and cloud investment. Large operators continue to expand, buy campuses and lock in long-term electricity arrangements.

As seen above, the more worrying number is the 2.5GW or so that remains in planning. We would be surprised if every one of those megawatts were built on the currently advertised timetable.

Johor's future will increasingly be decided project by project. A developer with a real hyperscale customer, confirmed grid access, a practical water strategy and long-term energy supply can still build an enormous business there. Another developer with little more than land and a beautiful rendering may sit in the pipeline for years.

That should pull Johor away from the anything-goes phase of the boom.

Singapore's reopening will take some workloads. Bangkok will win projects. Grid connections will slow developments. Water will become more expensive. Malaysian authorities will reject proposals that consume too many resources for too little economic benefit.

Johor can absorb all of that and keep growing.

The strongest reason is simple: the market has already crossed into real scale while demand remains tight. We are no longer betting that Johor might become a major data center hub one day. It already is one.

Our answer is yes, with a fairly high level of confidence. Johor’s data center boom will last. What probably will not last is the belief that almost every proposed campus can be built as quickly and cheaply as developers once expected.
