Why Datacentre Operators Are Prioritising Regions with Lower Energy Costs Over Traditional Locations
Introduction
Data centres have become the backbone of the digital economy, supporting everything from cloud computing to artificial intelligence and e-commerce. However, their enormous energy consumption presents a significant challenge for operators, especially as sustainability and cost-efficiency become critical concerns. Traditionally, data centres were built in regions with established infrastructure and access to major markets. However, a growing trend sees operators shifting to locations with lower energy costs, often at the expense of traditional business hubs. This analysis explores the key drivers behind this shift and its implications for the industry.
The Impact of Energy Costs on Datacentre Operations
The High Energy Demand of Data Centres
Data centres consume vast amounts of electricity, primarily for powering servers and cooling systems. Estimates suggest that global data centres use approximately 1-2% of the world’s electricity, with some hyperscale facilities consuming as much energy as small cities. Given this high demand, even slight variations in energy prices can significantly impact operating costs.
Historically, data centres were concentrated in metropolitan areas such as London, Frankfurt, New York, and Singapore. However, rising energy costs in these locations, driven by market fluctuations, government policies, and increasing demand for renewable energy, have made them less attractive for new developments. Operators are now evaluating regions where electricity is more affordable and stable.
Drivers Behind the Shift to Low-Cost Energy Regions
Energy expenses account for a substantial portion of data centre operational costs. By situating facilities in regions with lower electricity prices, operators can achieve significant savings. Countries such as Iceland, Canada, and certain areas of the United States (such as Oregon and Virginia) offer lower-cost electricity due to abundant natural resources like hydroelectric, wind, or geothermal energy.
Sustainability concerns and government regulations are pushing data centre operators to adopt greener energy sources. Many low-energy-cost regions also have strong renewable energy infrastructures, making them appealing for companies seeking to reduce their carbon footprint. Scandinavian countries, for example, benefit from hydroelectric power, while Texas and Australia provide access to large-scale solar and wind energy projects.
Many governments are actively courting data centre investments by offering tax incentives, grants, and discounted electricity rates. In the United States, states such as Iowa and Ohio have attracted major data centre investments by offering tax breaks on equipment purchases and energy consumption. Similarly, Ireland and parts of Eastern Europe provide financial incentives to encourage data centre development.
The cost of cooling data centres can be as high as powering the servers themselves. Regions with cooler climates naturally reduce the need for artificial cooling, leading to lower operational costs. Nordic countries, for example, provide ideal conditions for free air cooling, further reducing energy expenses.
Land and Infrastructure Availability
Major urban centres often struggle with space constraints and high real estate prices. Conversely, regions with lower energy costs frequently offer ample land at a fraction of the price. This availability allows operators to build expansive, cost-effective campuses with room for future expansion.
Challenges and Considerations
While shifting data centre operations to low-energy-cost regions offers many advantages, it also presents challenges that operators must carefully navigate.
One key reason traditional hubs remain attractive is their proximity to major population centres, which reduces latency for users. Moving to remote locations with lower energy costs may introduce network latency issues, requiring investment in additional fibre-optic infrastructure to maintain service quality.
Some regions with low energy costs may also have political or economic instability, which can pose risks for long-term investments. Countries with uncertain regulatory environments, inconsistent government policies, or geopolitical tensions may deter data centre operators from committing to these areas.
The availability of skilled IT and engineering professionals is crucial for data centre operations. Traditional hubs often have well-established tech ecosystems, whereas emerging low-cost regions may lack sufficient talent pools. Operators must consider workforce availability or plan to invest in local education and training initiatives.
While some low-energy-cost regions boast abundant renewable energy, others rely on fossil fuels to keep costs down. Companies committed to sustainability must assess whether these locations align with their long-term environmental goals and corporate social responsibility commitments.
Case Studies: Successful Data Centre Relocations
Iceland has become a leading destination for data centres due to its low-cost, 100% renewable energy powered by hydroelectric and geothermal sources. Companies like Verne Global have set up operations in Iceland to leverage the country’s stable, green energy supply and naturally cool climate.
Northern Virginia has become a data centre hotspot due to its relatively low energy costs, strong fibre connectivity, and business-friendly policies. Major cloud providers, including Amazon Web Services, Google, and Microsoft, have invested heavily in this region, making it the largest data centre market in the world.
Singapore has historically been a major data centre hub, but rising electricity costs and government-imposed moratoriums on new data centres due to sustainability concerns have prompted operators to consider nearby Malaysia and Indonesia. These countries offer lower energy costs while maintaining proximity to Singapore’s financial and technological ecosystem.
Future Outlook
As data consumption continues to rise, data centre operators will increasingly seek locations that provide both cost savings and sustainability benefits. Advances in edge computing may allow operators to distribute workloads more strategically, reducing the latency issues traditionally associated with remote data centres.
Emerging technologies such as liquid cooling and AI-driven energy management may also help mitigate some of the cost pressures faced in traditional hubs, allowing for more flexibility in location selection. However, the trend of prioritising regions with lower energy costs is likely to continue as operators strive to balance economic efficiency with environmental responsibility.
Conclusion
The shift towards data centre locations with lower energy costs reflects the evolving priorities of the industry. While traditional business hubs still offer advantages in connectivity and infrastructure, the economic and environmental benefits of lower-cost regions are becoming too significant to ignore. Operators must carefully weigh factors such as energy availability, sustainability, political stability, and connectivity when making location decisions. By strategically selecting new data centre locations, operators can ensure long-term profitability while contributing to a more sustainable digital future.
