The AI data challenge
Data explosion
AI-driven applications generate vast amounts of data. Generative AI (GenAI), which can create text, images, and video, uses large language models (LLMs) to process massive datasets.

From autonomous vehicles and smart security cameras to AI-powered mobile phones and ChatGPT, AI depends on seamlessly processing this mass of data in real time. That requires resilient, high bandwidth, low latency connectivity.
As a result, global network traffic is expected to rise sharply over the next few years, primarily driven by AI-upgraded applications.

Data centre growth
To meet this rising data tide, businesses will need high-capacity connectivity to data centres to ensure fast, low latency connections. Global spending on data centre systems is forecast to grow by around 24% in 20247, primarily driven by training needs for GenAI.
In the United Kingdom data centre power usage is set to surge six-fold over the next 10 years8.
However, data centre development in London and the South of England faces significant challenges due to power and space constraints, leading to tier 2 and tier 3 markets rapidly expanding.

Data centre growth
To meet this rising data tide, businesses will need high-capacity connectivity to data centres to ensure fast, low latency connections. Global spending on data centre systems is forecast to grow by around 24% in 20247, primarily driven by training needs for GenAI.
The United Kingdom Data Center Market size is estimated at 2.19 MW in 2024, and is expected to reach 3.61 MW by 2029, growing at a CAGR of 10.49%. Indeed, data centre power usage is set to surge six-fold over the next 10 years8.
However, data centre development in London and the South of England faces significant challenges due to power and space constraints, leading to tier 2 and tier 3 markets rapidly expanding.
Regional trends
In contrast, regions like Scotland are becoming increasingly attractive thanks to their high renewable energy potential and cooler climate, which reduces data cooling costs. In Scotland, renewable energy output has doubled over the last decade, and more is in the planning pipeline.

Meanwhile, Nordic countries like Sweden and Finland are also attracting data centre investment thanks to their cool climate, abundant renewable energy resources and more cost-effective energy tariffs. This will drive a greater demand for connectivity in northern UK, both to support local data centre needs in Scotland and to backhaul traffic destined for the Nordics.
How will this explosion of data and data centres impact business networks? How will business networks adapt to this changing demand?
