Asia Pacific in brief
Johor, which borders Singapore, had 20 operating data centres using about 920 MW of electricity in March 2026, and 5,628 MW of approved capacity across 28 projects, according to the Johor state government.
India's operational capacity reached nearly 1.8 GW in H1 2026, up from around 400 MW in 2019, with a pipeline of nearly 3.9 GW, according to Cushman & Wakefield.
Singapore still rations new capacity: in August 2026 EDB and IMDA provisionally allocated 200 MW to four operators under DC-CFA2.
Batam, an Indonesian island near Singapore, has 16 data centre projects in BP Batam's pipeline but only 2 operating, and BP Batam says power and water must be added first.
Korea is pairing AI data centre plans (SK and AWS in Ulsan, OpenAI with Samsung and SK) with a hard lesson: the September 2025 battery fire at the state data centre in Daejeon took 709 government systems 95 days to restore.

Built versus pipeline
Built versus pipeline: what each market reports (MW)
Each pair comes from one source in one market, so compare within a market, not across markets. Johor counts actual electricity use of operating sites against approved capacity. India counts operational capacity against under-construction and planned projects. Batam compares the island's whole generating capacity with one signed data centre power contract. Dashed bars are projected, darker bars are live, teal bars are confirmed.

How much data centre capacity is there in Asia Pacific?
Nobody publishes one total for Asia Pacific, because each country counts in its own way.
Why it matters Adding them up would be like adding miles and kilometres, so we show each country's figure with its own source.
Singapore: over 1.4 GW (May 2024)
India: nearly 1.8 GW running (first half of 2026)
Johor, Malaysia: around 920 MW of power in use (March 2026)

What happened in the South Korea data centre fire?
A battery in a South Korean government data centre exploded while being moved, and hundreds of public online services went down for months.
Why it matters UPS batteries are the backup batteries that keep computers on during a power cut. Here the backup itself caused the failure.
Date: 26 September 2025
Around 650 services down at first

Is Singapore still limiting new data centres?
Yes. Singapore only lets new data centres in through government competitions, a bit like a raffle for a small number of slots.

Why is Johor a data centre hotspot, and what about water?
Johor sits right next to Singapore, which limits new data centres, so builders cross the border. The state is creating a separate water supply for industry to protect homes.

What is India's data centre capacity in 2026?
India has nearly 1.8 GW of data centres running and more than twice that again being built or planned.
Why it matters That is more than four times what India had in 2019.

Why is Batam attracting data centres?
Batam is an Indonesian island close to Singapore with cheaper land and existing undersea internet cables. But power and water must be added first.
Why it matters Only 2 of the 16 projects there are running so far.

Is OpenAI building data centres in Korea?
Not yet confirmed. OpenAI signed agreements in October 2025 to explore building in Korea with the government, SK Telecom and Samsung companies.
Why it matters These are agreements to look into it, not buildings under way, so we label them as plans.
