ever,investor appetite for digital infrastructure is increasing,but the industry faces a serious challenge in its ability to meet both current and future demand.The lack of available power for ever larger data centre schemes is possibly the most talked-about challenge in the data centre sector.This year,our research provides tangible evidence that a lack of available capacity within the grid has started to have an impact on the rate of development.Our data shows that an accelerating commitment to develop new data centre capacity is not coinciding with an increase in projects under construction.This trend,first observed in the APAC region in 2023,can now be seen in the United States,where a hitherto uninhibited rate of increase in construction began to flatten out in mid-2024.The slowdown in the rate of construction commencing is in complete contrast to demand,with record global take-up increasing by 30%on 2023 figures for a total of 12,975MW across both colocation and self-build schemes.Public cloud remains the largest user of space with 52%of known take-up.While AI has been discussed as a major driver of demand for digital infrastructure,dedicated AI deployment only accounted for 11%of take-up.Demand from AI take-up is however increasing rapidly and has roughly doubled each year since 2022.There are several possible outcomes for the sector.Excess demand and a constrained supply pipeline will in the short term most likely lead to continued increases in colocation rents which we have already observed in EMEA and Americas regions,and which we predict will also follow on to APAC in the near future.A special thanks to the analysts of DC Byte who patiently reviewed seven-and-a-half thousand data centre schemes over the past year to produce this report.I hope you find it as informative as we have.Ed Galvin Founder and Chief EvangelistGLOBAL DATA CENTRE INDEX3 Copyright DC Byte 2025Executive Summary The fundamental driver of the data centre sector,demand for IT capacity,has never been stronger.But the very success of the industry places a new challenge for its participants to solve the emerging supply challenge.The ability of developers to bring to market enough supply to keep pace with demand is showing clear signs of challenge in our latest analysis.Live Supply grew by 26GW from 2019 to 2024,a 30%increase in the rate of growth seen from 2018 to 2023.Since 2019,new capacity delivered each year has increased by 2.2x.The rate of new schemes commencing construction between 2019 and 2024 has increased by 4x,generally trending with the increase in live capacity.In the past 18 months,however,growth of the Under Construction pipeline has slowed.New committed schemes in 2024,have increased by 3.7x since 2019 and is far outpacing the growth in Live and Under Construction capacity.That,combined with the trends in the Under Construction pipeline,illustrates the current bottleneck the industry is experiencing in efforts to bring future capacity to market.At the end of 2024,the distribution of new live supply growth has favoured the United States with 62%of IT power being built in the region in 2024 compared to 50%in 2023.Before 2023,the distribution of new IT capacity across EMEA,APAC and Americas regions remained broadly proportional at 25%,25%and 50%respectively.On the demand side,take-up of all capacity(both self-build and colocation)jumped by 29.8%compared to 2023 and continues an unbroken chain of year-on-year increases since 2015.The ability for the industry to service such demand is becoming strained,with space increasingly sold further up the development pipeline.Sold Live Supply has increased by 2.3x since 2019 while the amount of capacity sold while under construction has increased by 2.8x.Space sold before construction saw the steepest growth,increasing by a staggering 33x.Rents have consequently increased in the most developed markets globally,but has not surfaced as a universal trend,with APAC yet to be fully impacted by this.The Americas remain the global leading region on all accounts of supply,with 87%of total tracked capacity within the United States.The market now witnesses the impact of generative AI and high-performance computing demand needs,stacked on the continuing surge in hyperscale and cloud activity.Supply challengesparticularly power constraintsin the primary markets across North America are leading to significant growth in formerly alternative markets.Indexed growth rates point to standout markets including Alberta,Indiana and Bogota.Albertas rapid growth has been driven largely by a single large scale project,indicative of increasing occurrences of gigawatt level schemes announced globally.GLOBAL DATA CENTRE INDEX4 Copyright DC Byte 2025Notes:*Data for Mainland China is referential,and only based on key operators in the major metros.*Coverage of Russia has halted since the Russia-Ukraine war.New developments since,if any,will not have been captured in the data.Introduction The Global Index provides data-driven insights into the current data centre market landscape.The quantitative and qualitative insights are amassed from tracking over 7,500 individual data centres across the globe.Section I examines how global supply and demand have grown over the past five years.Section II provides insight into regional dynamics via analyses of supply categories in the Americas,Asia Pacific(APAC)and Europe,Middle East,and Africa(EMEA).Section III is a regional focus on the Americas,with the region noted as the global leader on all accounts of supply.Methodology DC Byte adopts a bottom-up approach in generating market-level analytics built from coverage of each individual facility.A unique range of sources are used,ranging from satellite observation imagery to parsing official earnings releases and public planning documents,speaking with stakeholders,and physical on site inspections.All data collected and presented in this publication is to the best of DC Bytes knowledge and experience.The Global Index tracks growth over a five-year timeline from 2019 to 2024.Supply and demand are analysed at a global level,along with supply growth across the three major regions:Americas,APAC,and EMEA.The report also includes a focused analysis of the Americas,featuring a comparative index highlighting growth across key markets,based on data captured in February 2025.GLOBAL DATA CENTRE INDEX5 Copyright DC Byte 2025Key DefinitionsLive SupplyDetermined IT power that is operational whether it is let or not.Under Construction(U/C)SupplyUnder Construction Supply is the estimated IT power that is currently having the mechanical and electrical plant installed to support it.Committed Supply Committed Supply is the estimated IT Load that we are highly confident will be added to a markets overall supply.This supply has the required elements(government,land,power,etc.)secured,or will be developed by an operator with a strong and reliable track record.Committed Supply could take the form of a data centre scheme which has yet to start construction,or it may refer to shell space in an existing data centre.The difference being that shell space can typically be fitted out in 3-6 months,while a scheme that has yet to start construction might take 1-2 years.Committed Supply does not mean sold space.Pipeline SupplyPipeline Supply is the sum of Under Construction and Committed Supply.Qualified SupplyQualified Supply is the sum of Live,Under Construction,and Committed Supply.Early Stage(ES)SupplyEarly Stage Supply is the IT Load that has been announced or speculated,but has yet to secure all of the required elements(government,land,power,etc.)for development.We do not hold full confidence in the development potential of this supply and it may require a major client precommitment for development to take place.Total SupplyTotal Supply is the sum of all four supply categories:Live,Under Construction,Committed,and Early Stage Supply.GLOBAL DATA CENTRE INDEX6 Copyright DC Byte 2025Section I:Global GrowthGLOBAL DATA CENTRE INDEX7 Copyright DC Byte 2025Global data centre growth has scaled new heights over the past five years.While data centre supply has accelerated significantly,demand has outpaced this growth at every stage of development.This is the key finding of our index of added supply and demand each year from 2019 to 2024.Global Supply Index(2019=100)IT GWCommittedUnder ConstructionLive2019202020212022202320242246904020200400600800The exponential growth in supply is spread unevenly across the categories of Live,Under Construction and Committed.New live supply has doubled,but this growth rate is far higher in the pipeline categories.Under Construction capacity has increased fourfold while committed schemes have increased sevenfold.The gap in pipeline capacity growth versus new live capacity growth reflects growing supply constraints.Moreover,the acceleration of committed projects versus schemes having shovels in the ground further underscores these challenges.Lengthening development timelines have been driven by permitting delays,supply chain disruptions and land and power constraints.GLOBAL DATA CENTRE INDEX8 Copyright DC Byte 2025Global Demand Index(2019=100)The analysis of demand shows a similar picture to supply.While demand for live capacity has doubled,pre-lease demand has surged with pre-leased under construction capacity growing threefold,whilst pre-leases of committed capacity have grown by 33 times.Demand continues to outpace supply.In 2024,the index of tracked supply showed a 1,000 point increase,whereas demand indexes rose by over three times the rate,increasing by 3,000 points.This reinforces a widening supply-demand gap.The stark differentials in under construction and committed pre-leases highlight another industry trend of lease structures in data centre operations having reshaped over the years.Space is being reserved further in advance,shifting from traditional anchor tenancy models to customer commitments signed well before construction commences.This consequent shift in demand exceeding supply has led to rent inflation,most evident in the United States and Europe,the Middle East and Africa(EMEA).Colocation rents in these regions have risen by over 30%in the last 24 months,driven by the accelerated take-up of capacity relative to the lower rate of increase in capacity coming online.This trend is most notable in the most developed data centre markets and not the Asia Pacific(APAC)region,where rent inflation has remained relatively stable,with the strong growth of Live Supply capacity outpacing that of the other regions.01010010002323302284201920202021202220232024CommittedUnder ConstructionLiveIT GW(Log10)GLOBAL DATA CENTRE INDEX9 Copyright DC Byte 2025As this rapid expansion continues,questions of oversupply arising from potentially slowing demand have emerged.Our trend analysis on demandby account of volume and increasingly advanced pre-leasesindicates otherwise.On all accounts,demand has undoubtedly exceeded supply,and can be expected to continue on this trajectory with added demand drivers alongside increasing supply bottlenecks.Discussions on AI as a key demand driver have proliferated industry conversations,following the landmark availability of ChatGPT to the general public in November 2022,and other generative AI platforms since.While AI holds the potential to tip the scales towards being the dominant absorber of data centre capacity,our data supports that it is still in the infancy stages of impacting global data centre demand.Yearly

to serve as the bedrock of data centre demand,driving approximately 50%of capacity take-up in recent years.By comparison,AIwhile growing rapidlyconstituted 11%of the known take-up use cases in 2024.The accelerating pace of pre-lease activity pitted against increasing supply bottlenecks suggests that demand will continue to outstrip available infrastructure.Looking ahead,the industrys biggest challenge will be innovation in sustainable solutions to the most pressing supply-side challengesparticularly power resourcing for mature marketsto deliver capacity at the speed of demand.41%39%33%IT GW0%25%50%75%100%20192020202120222023202450%11%55%12%50%9%41%11%3%45%49%8%6%37%52%6%11%31%AISocial MediaPublic CloudOthers,Financial Institutions,Public Sectors,MSP/SaaS etc.GLOBAL

dominant hub of data centre growth globally,maintaining a market share of Live Supply equalling the rest of the world combined from 2019 to 2024.0510152025EMEAAPACAmericasQ4 2024Q3 2024Q2 2024Q1

has come from the United States(US),with the remaining 8%and 2%split across Canada and Latin America(LATAM)respectively.The consistency of this continued expansion is attributable to the abundance and subsequent emergence of alternative markets in the US,as traditional primary markets have faced various limitations.Since the beginning of the spike documented in Q3 2022,regional supply growth has repeated a fairly consistent cycle.First,stakeholders identify a market as capable of meeting demand.This garners more widespread attention and investment,eventually snowballing into a significant run on new data centre schemes for several years.This persists until the identified market from 2019-2024 globally17.6%CAGR26.3 growthGWbecomes congested and constrained by power availability.At this point,operators shift their focus to alternative,typically untapped markets capable of meeting demand at a faster rate.This trend has been evidenced in the evolution of markets like Atlanta,Columbus,Phoenix,and other top-tier markets that were once considered secondary to major metropolitan areas and traditional tech hubs like New York,Northern Virginia,Silicon Valley and Chicago.Recently,with even fewer major metros left to turn to,the next phase in the development cycle has seen developers increasingly tar
