Europe’s power system is entering a period of accelerated change, with new technologies, operating models, and policy pressures reshaping how grids are planned and run. Against that backdrop, discussions held during EPRI’s 10th European Workshop Week reflected a broader reality facing the sector: existing frameworks are being tested by the pace and complexity of transformation.
The value of those conversations lay less in the gathering itself and more in the space they created for practical exchange. System operators, utilities, researchers, and technology providers compared notes on how research and innovation are translating into day‑to‑day operations—and where gaps between ambition and implementation still persist.
The ten insights that follow capture recurring themes from those discussions, highlighting practical priorities now being actively debated and refined by those closest to real‑world delivery.
1) Reliability is evolving due to electrification, complexity, and uncertainty
Europe's reliability challenge is driven by fast electrification, increased grid complexity, extreme events, and strategic uncertainty. Maintaining reliable service requires coordinated efforts, better risk detection, and flexible operational strategies.
As electrification accelerates, more sectors and services are becoming tightly linked to the power system, increasing the impact of disruption and raising expectations for resilience. System operators now face increased pressure to predict challenges sooner, adapt faster, and handle reliability amid greater uncertainty.
2) Innovation isn’t the bottleneck—implementation is
Innovation programming focused not just on generating new ideas, but on applying innovation within utilities through internal collaboration, governance, and execution. While many pilot projects exist, scaling them is challenging due to the need for operational, digital, and regulatory alignment.
As Durgesh Manjure, EPRI’s Vice President of Integrated Grid & Energy Systems, said, “There's broad alignment on the drivers of risk. What is changing is really the recognition that progress depends not only on developing new solutions and technologies and capabilities, but also ensuring a collaborative, coordinated path forward to make sure that we consider a holistic system needs to make sure that we build a safe, reliable and affordable electric system in the future.”
3) Modeling and validation must keep pace with a more digital grid and large loads from data centers
As AI and data centers expand, better modeling, validation, and practical implementation are increasingly essential. Evolving technologies require updated practices to ensure effectiveness in real-world power systems.
Participants emphasized the importance of using the right level of model reliability, supported by stronger screening methods, clearer governance, and better use of generic and performance-based models. Validation is also becoming more structured, blending benchmark tests with operational data to build confidence in real world behavior.
Taken together, these shifts reinforce a clear message: modern modelling is not an academic exercise. It is a practical, system level capability that underpins planning decisions, operational readiness, and the reliable integration of new technologies at scale.
4) Transmission operations are adapting to a faster, more dynamic system
Transmission operators are already working in a system that moves faster, behaves less predictably, and leaves less margin for error. As inverter-based resources, large l loads from AI, and tighter operating conditions become more common, traditional assumptions about grid behaviour are being tested.
This ongoing transformation is reshaping daily operations, leading to a stronger dependence on real-time awareness, enhanced monitoring of oscillations and system stability, and more frequent use of advanced decision-support tools within control rooms. Operators are now prioritizing coordination across regions, control centers, and disciplines to ensure rapid responses when conditions shift.
Keeping the system reliable now depends as much on modern operational tools, training, and coordination frameworks as it does on physical infrastructure. Transmission operations are evolving from managing a largely predictable system to actively navigating a more dynamic grid.
5) Distribution & DER: digitalisation and customer tech are rewriting the rules
A key takeaway is that the rapid expansion of customer-owned technologies—such as EVs, heat pumps, rooftop PV, and storage —is redefining the planning and operation of distribution networks. Digitalization is no longer just a useful tool; it has become essential infrastructure for distribution system operators (DSOs).
Another important insight is the increasing need for DSOs to have much greater visibility and control at medium- and low-voltage levels. Achieving this depends on interoperable data platforms, modern SCADA systems, and advanced tools in control rooms. Moreover, consistency is crucial to progress from pilot projects to solutions that can be scaled and reliably operated.
Innovation only delivers value when it can be translated into processes DSOs can reliably run every day. Digital tools, flexibility markets, and customer participation must be designed with execution in mind to allow DSOs can safely integrate new technologies while keeping networks reliable, secure, and ready to grow.
6) Renewables are entering a new phase: performance, reliability, and value
As wind and solar fleets mature, the focus is shifting from capacity growth to operational excellence. Even small performance losses now have material financial impacts, putting availability, reliability, and O&M discipline front and centre.
Solar operations are increasingly using inverter-level benchmarking and predictive diagnostics to improve reliability and maximize lifetime value. In wind, operators rely on SCADA-based analytics and health monitoring to detect performance issues early, minimize downtime, and control operating expenses.
Across both technologies, data driven performance and reliability are becoming essential to protect revenue and deliver long-term value from renewable assets.
7) Data centers: flexibility becomes essential to speed‑to‑power
Rapid growth in data centers—driven in large part by AI—has made large loads a central grid challenge. At European Workshop Week, discussions focused on how flexibility can unlock capacity and accelerate connections without undermining reliability or affordability.
Through EPRI’s DCFlex initiative, participants explored a common framework, Flex MOSAIC™, for classifying data center flexibility, giving system operators clearer signals on response speed, duration, and certainty. This can help reduce planning uncertainty, support faster interconnection, and link large load flexibility directly to the grid.
Demonstrations reinforced a clear takeaway: data centers are moving from passive consumers to active, grid responsive participants—and flexibility will be key to integrating them at scale.
8) Energy storage is moving fast—but deployment is still constrained by bankability, grid integration, and safety
Energy storage discussions focused on emerging technologies, deployment lessons, and the planning and safety considerations required for successful integration.
Where the conversation got especially practical was in what’s holding deployment back: conservative financing environments, grid connection challenges, and the need to translate technology promise into compelling business cases and implementation readiness. Safety and reliability were treated as central—not optional add-ons.
9) AI is moving from hype to operational reality—and success depends on foundations, not flash
The most revealing insight from the AI discussions was not about new capabilities, but about restraint. Utilities are beginning to recognise that value from AI does not come from deploying the latest model, but from embedding intelligence into the way engineering and operational decisions are already made. The challenge is less about what AI can do, and more about what organisations are prepared to trust, govern, and sustain.
This is where domain‑specific approaches matter. AI that understands power‑system context—rather than generic automation—emerged as the differentiator, reinforcing why EPRI’s work on tools like Raphson and initiatives such as Open Power AI (OPAI) is focused on orchestration, transparency, and repeatability. The emphasis is on AI that augments expert judgement, leaves an auditable trail, and fits within existing planning and operational disciplines.
Underlying the discussion was a clear hierarchy of priorities: affordability over novelty, safety over speed, and integration over experimentation. Cybersecurity, data governance, and decision auditability are shaping what is considered acceptable AI, not as constraints but as enablers of trust. The insight was clear—AI’s next phase in the power sector will be defined not by ambition, but by discipline.
10) Collaboration is becoming essential infrastructure for reliability
One of the clearest signals from the discussions was that collaboration itself is now a reliability enabler. EPRI’s model reflects a growing recognition that no single organisation has full visibility of today’s power system challenges.
As grids become more interconnected, many of the toughest issues now sit at the interfaces: between TSOs and DSOs, planners and operators, utilities and large customers, and technology providers and regulators. In this environment, shared learning is not a “nice to have”—it is a practical way to surface operational reality, reduce duplicated effort, and shorten the path from insight to implementation.
Taken together, these ten insights reflect a sector that is aligned on the challenges ahead, but increasingly focused on how to deliver solutions in a system growing more complex by the day. European Workshop Week made clear that progress will depend on stronger coordination, clearer decision‑making, and closer collaboration across transmission and distribution. By translating shared understanding into practical, scalable action, the industry can continue to build an electricity system that remains safe, reliable, and affordable as Europe’s energy transition accelerates.
