Battery storage firms eye AI demand but face grid, supply hurdles | Reuters

Executive summary

US battery storage firms are experiencing increased interest from AI data centres due to their escalating power demands. However, the industry faces significant hurdles, including lengthy grid connection queues and a supply chain heavily reliant on China, which impede rapid expansion.

Reporting based on reuters.com

Why it matters

For the UK, this report from the US highlights analogous challenges that could arise as AI infrastructure expands. If British data centres follow similar growth trajectories, the UK's energy system must be prepared for increased power demand, grid integration issues, and potential supply chain vulnerabilities for battery storage, which is crucial for grid stability and renewable energy integration.

Sector impact

Analysis by AI Energy Intelligence UK

UK electricity demand

The report indicates that power demand from data centres in the US could rise significantly, potentially reaching 9% to 17% of the total electricity supply by 2030, compared to approximately 4% today. This suggests a substantial increase in electricity consumption driven by AI infrastructure.

UK energy security

The heavy reliance of the battery supply chain on China is identified as a bottleneck, particularly as tax credit rules in the US increasingly favour non-Chinese sourcing. This highlights a potential energy security vulnerability for nations, including the UK, if diverse and resilient supply chains for critical battery materials are not developed.

Businesses

Battery storage companies are seeing increased business opportunities from AI data centres, with some firms engaged in significant projects globally. However, the industry's ability to capitalise on this demand is constrained by interconnection delays and supply chain issues, affecting growth and deployment timelines.

Quotations

"Supply chain constraints and interconnection queues are two of the most important barriers."

Harvest-Time Obadire

"Batteries will be an essential resource at data centers reliant on onsite gas generation, as gas generators are not fast enough to follow volatile AI data center demand."

Ben Hertz-Shargel

"This is an opportunity to scale US manufacturing which otherwise would have been priced out of the market, but sourcing materials from outside of China still needs to be developed further."

Chris Dendrinos

"Were it not for multi-year interconnection queues, we could deploy a utility-scale battery storage system in under a year to meet the needs of the electric grid."

Julian Nebreda

Long-term implications

The significant projected increase in power demand from AI data centres points to a long-term shift in electricity consumption patterns. The reliance on battery storage for grid stability and to manage demand spikes will grow, necessitating robust grid infrastructure and diversified supply chains to support this expansion and ensure a stable energy future.

Frequently asked questions

What is driving the increased interest in battery storage from data centres?

Power-hungry AI data centres are increasingly interested in battery storage to smooth power demand, optimise transmission-line capacity, manage demand spikes, reduce power consumption when the grid is strained, cover temporary outages, and lessen reliance on diesel generators.

What are the main challenges for rapidly scaling battery storage capacity?

The main challenges are lengthy interconnection queues to connect to the grid, which can take multiple years, and supply chain constraints, particularly the heavy dependence on China for key battery materials.

How much could data centre power demand increase by 2030?

According to the Electric Power Research Institute, power demand from data centres could reach 9% to 17% of US electricity supply by 2030, or up to 790 terawatt-hours, up from around 4% today.

Why are batteries considered essential alongside natural gas generation for data centres?

Batteries are essential because natural gas generators are not fast enough to respond to the volatile demand from AI data centres, making batteries crucial for maintaining stable power supply.
