How AI Is Transforming Energy: A Technological Revolution Reshaping the Industry

Artificial intelligence, battery energy storage systems, faster electricity trading and a growing emphasis on cybersecurity are reshaping the energy sector. The industry is undergoing a profound transformation that will affect not only energy professionals but also businesses and households. Which trends will define its future?

The European energy sector is experiencing one of its most significant transformations in decades. The growing share of renewable energy sources, digitalisation and new regulatory requirements are changing the way electricity is generated, traded and managed. These topics were at the centre of this year's Unicorn ​Energy Forum, which brought together transmission system operators, energy companies and technology providers from the Czech Republic and abroad.

The Energy Sector Is More Complex Than Ever Before

Only a few years ago, electricity generation was relatively predictable. Today, however, the power system is integrating an increasing number of renewable energy sources, whose output depends on weather conditions. At the same time, cross-border interconnections between European grids are becoming stronger, while new flexibility requirements continue to emerge.

The importance of responding to these changes was highlighted by the large-scale blackout that affected Spain and Portugal in 2025, disrupting electricity supplies for millions of people. The subsequent investigation showed that the outage was not caused by a single failure but by a combination of several factors occurring within a very short period of time.

"There was no single root cause. It was a combination of several events that unfolded within a very short time. This makes it even more important to strengthen coordination among all participants in the energy system and to respect the physical principles on which the energy sector is built," ​said ​Jan Jůda, Team Leader in Real-Time Operations at ČEPS, during the conference.

AI as an Assistant, Not a Replacement for Humans

As the volume of data continues to grow, the work of power system operators is changing as well. The amount of information they need to process has increased to such an extent that maintaining situational awareness across the entire power system would be increasingly difficult without advanced analytical tools.

This is where artificial intelligence comes into play. AI helps identify unusual events, detect potential issues and analyse vast amounts of data. In critical infrastructure, however, its role remains clearly defined.

"In critical infrastructure, the goal is not to deploy AI as quickly as possible. The goal is to deploy it in a way that we can still justify ten years from now. Artificial intelligence must be safe, transparent and remain under human control," explained Přemysl Voráč, Head of AI at ČEPS.

Experts at Unicorn share a similar view. In their opinion, modern systems are evolving into intelligent assistants rather than autonomous decision-makers.

"Today's operators work with enormous amounts of information and must coordinate system operations across multiple countries in near real time. Modern systems help them identify risks and connections more quickly. However, responsibility for the final decision will always remain with people," added Petr Svoboda, Senior Consultant at Unicorn.

Faster Trading and Battery Storage Strengthen Grid Stability

The transformation of the energy sector extends far beyond electricity generation. Significant changes are also taking place in electricity markets. One of the most important developments is the transition from hourly to 15-minute trading intervals. These shorter intervals provide market operators and transmission system operators with a more accurate picture of electricity generation and consumption, enabling them to respond more quickly to imbalances and match supply with demand more efficiently.

Battery energy storage systems will also play a key role. They can respond within seconds and help stabilise the grid during sudden fluctuations in electricity generation or consumption.

For consumers, this means greater confidence that electricity supplies will remain reliable even as the share of renewable energy sources continues to grow.

Data Will Define Trust and Security

Another major trend is the increasing emphasis on transparency and high-quality data management. Today, data forms the foundation not only for power system operation but also for electricity markets and the further development of green electricity.

Until recently, it was often sufficient to demonstrate that a certain volume of electricity had originated from renewable energy sources over the course of a year. New approaches, however, are moving towards much more precise tracking of electricity origin. In the future, it should be possible to verify whether the electricity consumed during a specific hour was actually generated by a renewable energy source operating at that same time.

"Data transparency is not merely a matter of regulatory compliance. It is one of the fundamental prerequisites for a well-functioning market in which all participants have access to the same information. This strengthens trust and contributes to consumer protection," said Jiří Hellus, Senior Consultant at Unicorn.

Although most of these changes remain invisible to the average consumer, their importance will continue to grow in the years ahead. The energy sector is evolving from traditional infrastructure into a digitally managed system that must continuously balance electricity generation and consumption every second.

The ability to maintain this balance will determine how reliably, securely and efficiently electricity systems operate in an era of an ever-growing share of renewable energy sources.
