How Singapore’s data centre operators are tackling government sustainability goals

Data centre operators in the Singapore market largely back the government’s push for environmentally sustainable development of data centre infrastructure, but challenges remain.
In a written reply to a Parliamentary question on new data centres, Singapore’s Minister for Trade and Industry, Chan Chun Sing, reiterated the government’s sustainability goals associated with energy and water-hungry data centre infrastructure.
“Singapore’s political stability and reliable infrastructure are conducive for operating DCs [data centres]. However, DCs are intensive users of water and electricity,” Chan Chun Sing said in the Parliamentary reply, published in February. “We will thus need to manage the DC ecosystem to ensure that it is environmentally sustainable, while supporting our business needs.
“We will strive for quality, not quantity – this means we seek to anchor a range of DCs that can meet both industry and society’s needs, are best in class in terms of resource efficiency, and that continuously innovate to push the boundaries of resource efficiency of DCs in a tropical climate,” he added.
In the last five years, Chan noted, 14 data centres with a total capacity of 768 MW were approved to be constructed on industrial State land in Singapore. This, he claimed, was a rapid increase compared to the 12 data centres, comprising a total capacity of 307 MW, in the preceding five-year period.
“The government therefore decided to moderate the growth of DCs with a temporary pause on the release of State land for DCs, as well as the development of DCs on existing State land,” Chan said. “The government informed the industry in 2019 and has been consulting them on ideas to enable their growth in a sustainable manner.
Now, according to Chan, the government is concluding its review and will be sharing its plans with the industry later this year.
For data centre providers operating in Singapore, the move has complicated recent development plans to some degree.
However, at least two big companies in the local data centre game back the government’s efforts to balance environmental sustainability with technology infrastructure development – providing it doesn’t hamper the future development of such infrastructure too much.
Mark Smith, Asia Pacific managing director of global data centre provider Digital Realty, said that although sustainability was important globally, data centres are only going to become more vital to the local economy over time, meaning that a sustainable approach to data centre growth in Singapore was ‘critical’.
“We believe sustainability is a global mandate and not just specific to Singapore,” Smith told Channel Asia. “It would be a key priority in the Asia Pacific region, going forward. Singapore is leading the way in driving the sustainability agenda in the region.
“The recent unveiling of the Singapore Green Plan 2030 and the new edition of the Singapore Green Building Masterplan early this year will make a positive impact. That said, data centres are the bedrock of the digital economy and the industry is only set to grow with increasing reliance on digitalisation.
“Working towards sustainable data centre growth would be critical for Singapore to retain its digital competitiveness and status as a global data centre hub,” he added.
Digital Realty has three data centre campuses in Singapore. Its Digital Loyang II or SIN12 campus, which is its latest data centre in Singapore, was approved for construction before the government’s moratorium came into effect in 2019.
Digital Loyang II, a multi-story, 50-megawatt facility, was officially opened in early April this year. The new site joined two pre-existing data centre sites in the country, Digital Jurong or SIN10 and Digital Loyang I, also known as SIN11.
Smith pointed out that, with Singapore’s push to go green, more businesses would be aware of their environmental footprint and act upon being more sustainable – a trend that he welcomed, stressing that the government’s actions have not deterred the company from continuing to maintain its presence in the Singapore market.
“We believe that all stakeholders including industry, academia and government have to come together to realise the green vision,” he said. “Sustainability is a core tenet for Digital Realty, and we acknowledge that balancing digitalisation and sustainability will be the key to the future.
“Singapore will continue to be a strategic market for Digital Realty,” he added.
Fellow data centre operator AirTrunk also received approval for its SGP1 hyperscale data centre site in Singapore, securing land allocation in Loyang for its SGP1 hyperscale data centre, before the government’s ‘pause’ came into effect.

AirTrunk’s SGP1 facility was launched in December last year, with the company claiming at the time that it was Singapore’s largest and most efficient independent data centre.
The company maintains that SGP1’s design power usage effectiveness (PUE) is the lowest in the market, coming in well below Singapore’s Building and Construction Authority (BCA) Green Mark Platinum marks in terms of energy efficiency.
Since it opened SGP1, AirTrunk has seen the ‘significant’ demand that exists in the local market.
Like Digital Realty, AirTrunk has taken a stance that aligns it with the Singapore government’s efforts to put sustainability before development – or at least try to strike a reasonable balance between the two.
“We are completely aligned on the need to develop data centres in a considered manner to balance the demand for critical hyperscale data centre capacity with Singapore’s objectives including climate targets and its national development strategy,” a spokesperson for AirTrunk told Channel Asia.
From AirTrunk’s perspective, modern data centres, like its freshly launched site, are built with energy efficiency in mind and could actually represent a larger opportunity for Singapore to be more sustainable if businesses move their workloads to such infrastructure, the government’s development pause notwithstanding.
“Hyperscale data centres, like AirTrunk SGP1, significantly bring down average energy and water use,” the company’s spokesperson said. “The faster that businesses migrate data to the cloud from less efficient on-premise or smaller data centres, the more meaningful the energy and water usage efficiencies that can be achieved.”
However, as noted by Smith, AirTrunk also conceded that new data centres are an essential ingredient in Singapore’s economic prosperity, meaning a way forward must be struck between ensuring sustainability goals while creating the infrastructure needed to support the market – and access to the right kind of energy production will play role.
“Building high quality data centres is a vital step to enable Singapore to continue its technology evolution to be a major Asia Pacific digital hub,” the AirTrunk spokesperson said. “The challenge in this market is the ability to access the level of clean energy required to power data centres.
“Our focus is on how we effectively leverage our scale to support and fast-track the transition to a clean energy future, including supporting Singapore’s accelerated transition to sustainable energy, scaling up the ‘Four Switches’ to transform the power grid and the ‘Green Plan’, and considering importing renewables or bringing in green hydrogen,” the spokesperson said.
