The expansion in information centres brings with it elevated vitality calls for and because of this the usage of energy has grow to be the primary subject for his or her operators globally.
In response to the International Energy Agency (IEA) electrical energy consumption from information centres, synthetic intelligence (AI) and the cryptocurrency sector might double by 2026, with information centres being vital drivers of development in electrical energy demand in lots of areas. They used an estimated 460 terawatt-hours (TWh) in 2022 and are projected to eat greater than 1000 TWh by 2026 (a requirement stage roughly equal to the electrical energy consumption of Japan).
Australia is seen as a rustic that can proceed to see development in information centres and Morgan Stanley Analysis have taken an in depth take a look at each the anticipated development in information centres in Australia and what it would imply for our grid. The expectation is the grid will be capable of accommodate the vitality demand from information centre development till 2030, however it might grow to be constrained within the 2030s as we see extra coal crops exit the market until there are effectivity good points or growth of recent technology. We take a more in-depth look.
Development
An estimated 4000 information centres (DCs) function globally and Australia is within the high 5, areas with the same capability to London. Cushman & Wakefield, a world actual property business providers firm that tracks DC developments, studies there have been DCs with 7.1 GW of complete energy necessities below growth throughout 63 markets in 2023. Since then, this had grown to 12 GW for all DCs below growth.

In response to the Mega Data Centre Market Size & Share Analysis – Growth Trends & Forecasts (2023-2028) report evaluation, the expansion within the digital financial system and the exponential rise in information consumption has seen sturdy development within the growth of “mega” information centres (see desk beneath for measurement definition). The mega DC market, valued at USD 23.23 billion ($37 billion) in 2023, is projected to increase to USD 29.34 billion ($44 billion) by 2028, rising at a compound annual development charge (CAGR) of 4.78 per cent in the course of the forecast interval.
Final yr, information centres noticed substantial development, pushed by a rise in synthetic intelligence and cloud computing. This improve in computing energy has additionally expanded the cooling capability wanted to guard to guard it and including pressure on vitality programs. In consequence a possible limiting issue would be the availability and worth of energy. Given this anticipated development in vitality demand, information centre operators are actually dealing with stricter rules, and higher stress to scale back their vitality use, in keeping with the Annual Global Data Center survey. In 2019 Singapore paused growth of recent information centre’s in response to their excessive vitality consumption. This was to purchase time for the federal government to conduct a evaluate on methods to develop the info centre trade in a extra sustainable manner.
Singapore imports most of its electrical energy and due to its year-round excessive temperatures and humidity, a major quantity of vitality is required to chill servers. Information centres are estimated to account for greater than 7 per cent of the nation’s electrical energy use now. The moratorium was lifted in 2022.
The Australian Scenario
Morgan Stanley Analysis forecasts that many of the load development in Australia is anticipated to emerge in New South Wales and Victoria.
General, MS expects information centre vitality demand to go from 5 per cent of complete nationwide electrical energy technology in Australia to eight per cent by 2030 – it might even attain as excessive as 15 per cent. In its base case, it expects information centre uninterruptible energy provide necessities to extend from 1050 MW in 2024 to just about 2500 MW in 2030, which is a 13 per cent improve (see determine 1.)
Determine 1 – Information Centre Forecast (Uninterruptible Energy Provide)
Supply: Morgan Stanley Analysis
MS’s most bullish situation forecasts that information centres might require 3777 MW in 2030, a 20 per cent development charge from 2023. Even its most pessimistic forecast sees an eight per cent development in uninterruptible energy provide necessities over the 2023-2030 interval to 1762 MW (see above).
By way of demand, MS forecasts that in its base case this might attain almost 23 TWh in 2030, an 18 per cent improve from 2023. Underneath its bull case, electrical energy demand may very well be as excessive as 43 TWhs by 2030, with New South Wales accounting for twenty-four.7 TWhs and Victoria an extra 9.4 TWh. The Nationwide Electrical energy Market presently provides about 200 TWhs to households and companies yearly.

Energy utilization effectiveness (PUE), or energy unit effectivity, is a ratio typically used to evaluate information centre effectivity. This offers a ratio of complete facility energy to the IT gear energy, with the best being thought-about a PUE of 1. Globally, the average annual PUE reported in 2022 was 1.55.
MS expects the PUE below its bull case to stay at 1.7, the estimated present score. Underneath its bear case this could fall to 1.2 and below the bottom case it could attain 1.35 by 2030 (see determine 3).

The Australian Federal Authorities is tightening vitality effectivity rules for information centres internet hosting federal company workloads. These modifications will mandate all information centre service suppliers to the federal government to attain a five-star score from the Nationwide Australian Constructed Surroundings Ranking System (NABERS).
The Digital Transformation Company (DTA) has established a brand new Information Centre Panel, which is designed to assist promote sustainable practices throughout information centres and help the Federal Authorities’s transfer in direction of ‘web zero’.
The brand new Information Centre panel replaces a earlier panel established in 2014 and features a strengthened vary of measures for information centre suppliers to determine, handle and scale back their greenhouse gasoline emissions. To be included on the panel, suppliers must:
- meet the necessities of the Authorities’s ICT Sustainability Plan for information centres
- adjust to emission thresholds below the Nationwide Greenhouse and Vitality Reporting Act
- use accredited Greenpower from renewable sources
- have a 5-star NABERS score or equal environmental score
- goal a PUE of lower than 1.4
- have a plan to fulfill web zero emissions by way of innovation, planning and funding.
Primarily based on common grid intensities based mostly on renewable vitality targets, MS estimates information centre Scope 2 emissions will attain 8 million tonnes, or round 2 per cent of Australia’s emissions and 40 per cent of our annual manufacturing of Australian Carbon Credit score Items.
How will we meet the brand new demand?
Morgan Stanley has outlined three eventualities to fulfill the demand that can come from development in information centres. The eventualities thought-about are:
- Fossil extension
- Renewable energy buy agreements (PPAs)
- Hourly-matched renewable energy
Fossil Extension
Making use of current however unused capability is “doubtlessly viable” however would additionally want extra funding in capability to handle peak demand durations (akin to gasoline turbines) and will considerably improve stress on energy costs and emissions.
Renewable PPAs
The report notes most information centres have renewable electrical energy procurement targets and suggests this could be the bottom price method for energy growth and energy costs. MS modelled 82 per cent of non-matched renewable electrical energy to mirror the present Federal Authorities renewables goal by 2030 in addition to establishment enterprise observe. That entails information centres coming into PPAs with vitality firms or builders to acquire large-scale technology certificates (LGCs), “ideally from new tasks to indicate additionality, however permitting the electrical energy market to resolve for load form, i.e., to match the precise energy demand for the info centres”. In its report, Cushman and Wakefield reported final yr it was common to see information centres enter PPAs for 200-400MW, whereas Google signed a 600MW PPA for its Texas amenities.
Hourly matched renewables energy
Thought of a extra aggressive renewable technique, this entails information centres shopping for renewable vitality in actual time. Morgan Stanley modelled this method utilizing outsized wind technology for steady load and outsized photo voltaic for daylight load with battery storage of round 6 hours per day to shift and canopy provide and demand gaps.
Different choices based mostly on abroad expertise embody gasoline cell expertise and co-location with nuclear, though it notes this stays unlawful in Australia. It additionally sees potential, with enough fiber, for world “comply with the solar compute”, making the most of cheaper solar energy. This is able to require firms to have, or to ascertain, information centres in a number of international locations.
