Chapter 3: Data Center Case Studies
Global Models for AI-Driven, Sustainable Infrastructure
As AI workloads become increasingly energy- and compute-intensive, the world’s leading technology companies are rethinking how and where data centers are built. This chapter showcases three case studies— Meta’s Project Cosmo , DayOne’s SIJORI strategy , and Kao Data’s Harlow campus —each demonstrating a different approach to high-performance, sustainable, AI-centric infrastructure development.
3.1 Meta’s Project Cosmo (Cheyenne, Wyoming)
Meta’s newest facility, Project Cosmo , exemplifies a next-generation, AI-specific data center model.
Key Facts:
Size : 715,000 sq. ft
Investment : $800 million
Operational Year : 2027
Power Source : 100% renewable (solar farm + energy trading partnership)
Cooling : Closed-loop liquid system (minimal water use)
Strategic Advantages:
Located in Cheyenne, Wyoming , selected for its cool climate , low taxes , and supportive regulatory environment .
Backed by a $1.2 billion solar energy project from Enbridge with 1.2 million panels and battery storage.
Integrated into Black Hills Energy’s real-time trading market (California ISO’s WEIM) for flexible energy sourcing.
Community Impact:
Meta committed to building sewer and water lines , and to not exceed the water usage of a typical 100-person business .
Grazing-compatible solar array design preserves some agricultural land use.
This case shows how AI-specific infrastructure, sustainability, and community partnerships are converging in modern hyperscale builds.
3.2 DayOne in the SIJORI Region (Singapore–Johor–Riau Islands)
DayOne, a Chinese technology infrastructure company, is executing a hub-and-spoke data center strategy across the SIJORI triangle — combining connectivity in Singapore, low-cost operations in Malaysia, and expansion capacity in Indonesia.
SIJORI Strategy Highlights:
Singapore : High-density hub in Jurong East; 20MW capacity; powered by hydrogen-ready fuel cells.
Johor, Malaysia : 120MW across two campuses; serves as cost-effective overflow for Singapore.
Batam, Indonesia : 72MW campus with direct subsea cable access to Singapore; built in collaboration with the Indonesia Investment Authority (INA).
Why it Matters:
DayOne leverages geographic synergy : regulatory strength in Singapore, low costs in Johor, and abundant land in Batam.
Its Batam campus is the first in Asia specifically designed for AI workloads .
DayOne aims to reach 100% renewable energy use by 2030, pioneering sustainability in Asia’s digital infrastructure market.
This model demonstrates how companies can de-risk energy and capacity challenges through regional distribution and diversification .
3.3 Kao Data’s Harlow Campus (United Kingdom)
Kao Data, based in the UK, has built the region’s first AI-native data center platform , optimized for high-density, GPU-intensive workloads like machine learning and high-performance computing (HPC).
Facility Highlights:
Location : Harlow, UK (15-acre campus)
Capacity : 40MW IT load
Design : Supports up to 80kW per rack and 480kW across AI pods
Cooling : Direct-to-chip liquid cooling (30% energy savings)
Power Use Effectiveness (PUE) : 1.2
Sustainability Commitments:
100% renewable electricity since 2018
Direct power matching with a wind farm in Kent
Use of hydrotreated vegetable oil (HVO) for backup generators
Transitioning to local Power Purchase Agreements (PPAs)
Strategic Connectivity:
Carrier-neutral with ultra-low latency to major cloud providers
<2ms latency to major European exchange points (e.g. London Internet Exchange)
Regulatory Alignment:
Fully compliant with UK energy and data protection laws
Classified as Critical National Infrastructure (CNI)
Kao Data illustrates how purpose-built AI data centers can balance cutting-edge performance, compliance, and environmental goals in mature markets.
Chapter Takeaways
Meta is setting a new bar for sustainability and local integration in the U.S.
DayOne shows the power of regional optimization and speed-to-market in Asia.
Kao Data exemplifies how Europe is addressing AI demands with low-latency, high-density, and climate-conscious facilities.
Each case reflects a shift toward AI-optimized, renewable-powered, and policy-aligned infrastructure —providing blueprints for the global data center industry.
