(Shah Alam, 8 September 2026) — Across Southeast Asia, the rapid proliferation of data centres has brought mounting scrutiny over whether host states can sustain the enormous utility demands that accompany each new facility. Concerns over strained electricity grids and dwindling freshwater reserves have followed the digital infrastructure boom from Singapore to Jakarta — and Selangor, Malaysia’s most data-centre-dense state, has not been immune to public anxiety. Reportedly, the Selangor state government moved to address these concerns directly, affirming that data centre project approvals in the state are contingent on verified water and power supply adequacy before any construction proceeds.
The Long-Standing Utility Strain in Selangor Continues to Trouble Residents and Industry Observers
The pressure on Selangor’s utility infrastructure has intensified over the past two years, driven by an accelerating wave of data centre investments that has positioned the state as one of Asia Pacific’s most sought-after digital hubs. For residents in districts surrounding these facilities, the fear is tangible: will the lights stay on, and will the taps keep running, once dozens of hyperscale campuses come online simultaneously?
Data centres are notoriously resource-intensive. A single large-scale facility can consume tens of millions of litres of water per day for cooling purposes and draw hundreds of megawatts from the national grid — equivalent to the power demand of entire townships. When multiple projects are approved and constructed within a compressed timeframe, the cumulative burden on shared infrastructure raises legitimate questions about grid stability and water security for existing communities.
Public concern has grown alongside the investment figures, with residents and civil society groups repeatedly raising questions about whether state authorities have adequate oversight mechanisms to prevent utility shortfalls before they materialise.
Why Utility Management for Data Centres Is So Hard to Get Right: The Underlying Reasons Are More Complex Than Expected
In fact, the challenge of balancing data centre growth against utility capacity is structural rather than merely administrative. At its core, the problem stems from a disconnect between the speed of private sector investment decisions and the longer planning cycles required for public utility infrastructure.
Electricity grid expansion, for instance, involves coordination between national utility provider Tenaga Nasional Bhd (TNB), federal regulators, and state-level authorities — a multi-layered process that can take years to execute. Water treatment capacity faces similar constraints: new plants must be planned, financed, permitted, and built well in advance of demand materialising, leaving a window during which approved projects could theoretically outpace available supply.
Additionally, data centre operators have historically negotiated utility access on an individual project basis, making it difficult for state planners to assess cumulative grid and water demand across an entire pipeline of investments. Without a coordinated vetting mechanism, the risk of approving more capacity than the network can support becomes significant.
Facing Data Centre Utility Risks, What Solutions Currently Exist on the Market?
Several approaches have emerged globally to manage the utility demands of large-scale data centre development. Some jurisdictions have imposed moratoriums on new approvals — Singapore famously paused data centre construction for three years before resuming with stricter energy and water efficiency requirements. Others have introduced mandatory sustainability ratings or cooling technology standards as preconditions for planning consent.
Water recycling systems and alternative cooling technologies, such as immersion cooling and air-side economisation, have gained traction as engineering solutions that reduce freshwater consumption by up to 90 percent in optimised configurations. On the power side, dedicated renewable energy procurement frameworks and on-site generation requirements have been adopted in parts of Europe and the United States to reduce grid dependency.
However, each of these approaches carries trade-offs. Moratoriums deter investment. Sustainability mandates require enforcement capacity that not all state governments possess. Technology requirements can increase project costs and slow deployment timelines. The result is that no single existing solution fully resolves the tension between rapid data centre expansion and reliable utility supply for existing users.
Selangor’s Approval Framework Was Created to Address Precisely This Gap
Against this backdrop, Selangor Mentri Besar Datuk Seri Amirudin Shari announced on 8 September 2026 that the state has established a structured, pre-approval vetting process specifically designed to prevent utility overcommitment. Speaking at a press conference following an NCT Alliance Bhd milestone event at the NCT Smart Industrial Park in Sepang, Amirudin stated that every proposed data centre must first secure clearance from federal committees and task forces before receiving state approval.
These assessments evaluate grid capacity from Tenaga Nasional Bhd and water availability from Air Selangor as mandatory prerequisites. No project receives a green light without confirmed utility adequacy. Amirudin confirmed that current water reserves are sufficient to support all projects already approved, and outlined that additional infrastructure is planned to accommodate future demand.
“When the Sungai Rasau Water Treatment Plant is completed, we will have another 700 million litres per day,” Amirudin said. “So, definitely, we think the supply is enough.”
To further reduce pressure on freshwater resources, the state is actively encouraging data centre operators to implement water recycling systems and adopt alternative cooling technologies. Amirudin also acknowledged the broader economic rationale for accommodating data centre growth, citing the sector’s potential to support the expansion of Selangor’s electrical and electronics industry, chip manufacturing operations, and semiconductor supply chains.
“The supply is also sufficient and we are very aware of the concerns of the public related to power and water supply,” he stated, directly addressing residents who have followed the sector’s rapid expansion with apprehension.
Frequently Asked Questions About Selangor’s Data Centre Approval Process
What is required before a data centre project receives approval in Selangor? Every proposed data centre project in Selangor must obtain clearance from federal committees and task forces that assess electricity grid capacity from Tenaga Nasional Bhd and water availability from Air Selangor before the state issues any approval.
Has the data centre boom strained Selangor’s water supply? Selangor Mentri Besar Datuk Seri Amirudin Shari confirmed on 8 September 2026 that current water reserves are sufficient to support all projects that have already received approval, with further infrastructure planned to meet future demand.
How much additional water supply will the Sungai Rasau Water Treatment Plant provide? When completed, the Sungai Rasau Water Treatment Plant will add 700 million litres per day to Selangor’s water supply capacity, according to statements made by Mentri Besar Amirudin Shari.
What measures are being taken to reduce data centres’ water consumption in Selangor? The Selangor state government is encouraging data centre operators to implement water recycling systems and adopt alternative cooling technologies as a condition of responsible operation, in order to reduce reliance on freshwater resources.
Who is responsible for vetting electricity supply for new data centres in Selangor? Tenaga Nasional Bhd (TNB) assesses grid capacity as part of the mandatory federal committee evaluation process that all data centre projects in Selangor must pass before receiving state approval.
What economic benefits does Selangor expect from data centre development? Amirudin Shari stated that data centre growth in Selangor is expected to support the expansion of the electrical and electronics sector, chip manufacturing, and the semiconductor industry within the state.
Does Selangor have the authority to halt data centre approvals if utility capacity is insufficient? The current framework means no data centre project receives state approval without first demonstrating that both electricity and water supply are adequate, giving the state an effective mechanism to limit approvals when infrastructure capacity cannot support additional demand.
Selangor’s Utility-Gated Approval Model Signals a Maturing Approach to Digital Infrastructure Growth
The framework outlined by Mentri Besar Amirudin Shari on 8 September 2026 represents a structured government response to one of the most pressing governance challenges accompanying Malaysia’s data centre investment boom. By requiring verified clearance from both Tenaga Nasional Bhd and Air Selangor before any data centre project approval proceeds, the Selangor state government has established a replicable model that directly links digital infrastructure expansion to demonstrable utility capacity — rather than allowing approvals to outpace the infrastructure available to support them. The completion of the Sungai Rasau Water Treatment Plant, which will add 700 million litres per day to the state’s supply, further underpins the state’s capacity planning for continued growth in this sector.
