As renewables, electrification and AI workloads reshape electricity demand, grid operators need greater flexibility and faster, smarter control to keep power systems reliable and affordable. Artificial intelligence is emerging as a key enabler: it can unlock hidden capacity on existing lines, improve forecasting and demand response, and reduce outage times—helping grids integrate more variable generation and new loads without relying solely on years of new infrastructure investment.
Why Flexibility and Reliability Are Now the Bottleneck
Global power systems are adding solar, wind, batteries and large new loads—from EVs to data centres—faster than transmission and distribution networks can be expanded. The International Energy Agency (IEA) has highlighted the growing importance of flexibility as power systems integrate more variable generation and changing demand patterns. Without sufficient flexibility, managing these changes can become more costly and complex.
At the same time, AI and cloud workloads are contributing to rapid electricity-demand growth, creating new challenges for grids that were not designed for such fast changes in load patterns.
How AI Unlocks Flexibility
AI strengthens grid flexibility in three key areas: better forecasting, smarter optimisation and faster control.
Improved forecasting: Machine-learning models can identify complex patterns in weather, renewable generation and electricity consumption. More accurate forecasts can help operators reduce reserve requirements, minimise renewable curtailment and identify potential congestion earlier.
Hidden capacity on existing lines: AI-enabled tools, including dynamic line rating and advanced grid-management systems, can increase the utilization of existing transmission infrastructure. The IEA estimates that AI could unlock up to 175 GW of additional transmission capacity globally and help save the power sector up to USD 110 billion per year by 2035 through improved operations and maintenance.
Smarter demand response: AI can coordinate distributed energy resources such as batteries, EVs, heat pumps and smart appliances, effectively turning them into flexible resources that can respond to electricity prices or grid-reliability signals.
Demand-response programmes have also demonstrated measurable potential for managing electricity demand in cities such as Accra and Kumasi, highlighting the value of flexible consumption in rapidly growing power systems.
How AI Improves Reliability and Resilience
Reliability is about keeping the lights on; resilience is about recovering quickly from disruptions. AI can support both.
Faster fault detection: AI-based systems can analyse grid data to identify and locate faults more rapidly. The IEA reports that AI-enabled fault detection and localisation can potentially reduce outage durations significantly, improving system reliability.
Predictive maintenance: By analysing sensor readings, equipment conditions and loading patterns, AI can help utilities identify potential equipment failures before they occur. This can reduce unplanned outages, improve maintenance planning and extend asset life.
Real-time stability: AI-enhanced control systems can help manage inverters, storage and flexible loads at high speed to support frequency and voltage stability. In a 2026 UK trial, National Grid and its partners demonstrated that an AI data-centre cluster could reduce its electricity demand by around 30% within 30 seconds during a simulated grid-stress event.
From Pilots to Production
Real-world deployments are increasingly demonstrating how AI and flexible computing loads can interact with the power system.
A coalition involving NVIDIA, Oracle, EPRI and other partners demonstrated a 25% reduction in AI workload power for three hours during a grid-stress test in Phoenix while maintaining the required level of computing performance. The demonstration used Emerald AI’s technology to dynamically adjust data-centre power consumption in response to grid conditions.
Researchers at Lehigh University have also developed an optimisation framework that coordinates data-centre workloads, batteries, solar generation and demand response. Their research reported approximately 20% lower data-centre energy costs while supporting grid flexibility.
The opportunity extends beyond data centres. The IEA estimates that widespread adoption of existing AI-enabled building optimisation measures could deliver around 300 TWh of global electricity savings, while AI applications in light industry could reduce process energy consumption by up to 8% by 2035 under its Widespread Adoption Case.
What Energy Leaders Should Do Next
For utilities, system operators, regulators and large energy users, the priority should be to move AI from isolated pilots into operational infrastructure.
•Deploy AI-enhanced forecasting for renewable generation and electricity demand at regional and distribution levels.
•Apply dynamic line rating and advanced congestion-management systems on critical transmission corridors.
•Develop automated demand-response programmes for large and flexible loads.
•Integrate batteries, EVs and other distributed resources into virtual power plants.
•Establish clear governance, cybersecurity and human-oversight frameworks for AI-enabled grid operations.
•Measure AI projects against operational outcomes such as reliability, flexibility, avoided curtailment, energy savings and reduced outage duration.
AI will not replace wires, substations or other physical grid infrastructure. Instead, it can help existing infrastructure operate more efficiently and respond more intelligently to changing conditions.
For energy systems navigating rapid decarbonisation, electrification and surging digital demand, that combination of physical investment and intelligent optimisation will be central to building a reliable, flexible and future-ready power grid.
Energy Evolution Awards & Conference 2027
The Energy Evolution Awards & Conference 2027 will take place on 16 March 2027 in Dubai. Organised by Next Business Media, the event brings together developers, investors, technology providers and policymakers working across renewables, energy storage, grids and smart-energy technologies.
AI, automation and intelligent energy systems are increasingly important to the evolution of modern power infrastructure. The 2027 conference provides a platform for organisations developing technologies and projects that improve energy efficiency, grid flexibility, reliability and system resilience.
