Europe’s energy transition has entered a decisive stage. What once appeared as a long-term objective is now embedded in the structure of the power system: renewable sources have become a central pillar of electricity generation across the European Union.
Progress is no longer driven primarily by the pace of new installations, but by how effectively power systems operate under increasingly high shares of renewables. This shift marks a change in priorities for policymakers, utilities, asset owners, and system operators.
The focus is no longer on how fast capacity can be added, but on how well renewable generation can be integrated, balanced, and managed within a system that is becoming more complex and more interconnected.
The following analysis reflects the current structure and dynamics of Europe’s power system, based on estimates derived from the most recent 2025 data.
A structural milestone for Europe’s power mix
Wind and solar have crossed a historic threshold. Together, they now account for 30% of total EU electricity generation, overtaking fossil fuels, which have fallen to 29%. When all renewable sources are considered, nearly 48% of Europe’s electricity is now generated from renewables – even in a year characterized by less favorable weather conditions, including lower wind availability and reduced hydropower output.
The remaining share of the electricity mix is largely covered by nuclear generation, which continues to account for roughly 22-23% of total EU electricity production. Nuclear remains a stabilizing component of the system, particularly in countries such as France. However, its contribution is structurally static and geographically concentrated, reinforcing the need for flexibility and advanced control solutions as variable renewables expand across a broader set of markets.
This milestone signals resilience. Europe’s decarbonization trajectory is no longer fragile or easily reversed by short-term external factors. At the same time, it reveals a more complex reality: the transition is progressing at different speeds across EU.
Northern and Western European countries such as Germany, Spain, the Netherlands and Denmark have already structurally integrated wind and solar into their power systems. By contrast, parts of Central and Eastern Europe – including countries such as Poland, Czech Republic, Hungary, Romania and Bulgaria – remain more dependent on thermal generation, with slower deployment of flexibility assets and grid modernization.
These differences increasingly reflect not only policy ambition, but system readiness – including grid flexibility, storage deployment and operational coordination.
Solar as the main growth engine
Solar power has emerged as the primary driver of Europe’s renewable expansion. EU solar generation reached a record 369 TWh, accounting for 13% of the total electricity mix and surpassing both coal and hydropower at the European level.
Italy stands out in this context: national solar generation increased by 24% year-on-year, reaching 17% of total electricity production. This growth reflects sustained investment and confirms solar’s role as a cornerstone of national decarbonization strategies.
At the same time, rapid solar expansion highlights structural vulnerabilities. As solar penetration increases – particularly during midday production peaks – curtailment is becoming a structural challenge in several European markets. Without coordinated control and storage integration, surplus generation is increasingly constrained by grid limits rather than resource availability, directly impacting asset revenues.
Despite higher renewable output, gas-fired generation increased by 8% across the EU in 2025, largely to compensate for reduced hydropower and to cover demand during peak hours. As a result, Europe’s gas import bill for power generation rose to €32 billion, up 16%, with Italy and Germany among the most exposed markets.
The message is clear: expanding renewable generation alone does not automatically reduce exposure to fossil fuels or price volatility. Without adequate flexibility and coordinated operations, system stress simply shifts in time rather than disappearing.
Wind power: resilience under pressure
Wind energy remains the largest renewable source in Europe’s electricity mix and continues to play a foundational role in the transition. In 2025, wind generation faced less favorable weather conditions, with lower average wind speeds affecting output in several markets. Despite this, wind maintained a structurally high contribution across the EU, confirming its long-term relevance within the power system.
The impact of weather variability was not uniform. Countries with strong offshore capacity demonstrated greater resilience, while others experienced higher fluctuations in production. This divergence highlights the geographical diversity of Europe’s wind fleet and the importance of balancing onshore and offshore assets across regions.
Rather than slowing progress, wind performance in 2025 reinforced a broader reality: as renewable penetration increases, system stability depends less on individual technologies and more on how different sources are combined, managed, and coordinated within the overall power mix.
Storage and flexibility move to the center
Analyses by Ember consistently identify energy storage – particularly batteries – as one of the most effective levers to reduce price volatility and dependence on imported fuels. Storage enables surplus renewable energy to be absorbed during periods of high production and released when demand rises, smoothing price fluctuations, and reducing the need for thermal backup.
Italy is emerging as a key player in this transition. The country accounts for roughly 20% of the EU’s large-scale battery capacity, with 1.9 GW already operational, second only to Germany. More importantly, the project pipeline exceeds 10 GW, signaling a strategic shift toward flexibility as a core system asset rather than a supporting technology.
This acceleration is supported by regulatory and market drivers, including capacity market mechanisms, ancillary services procurement and updated grid codes that increasingly reward fast-response flexibility. At this scale, batteries are no longer experimental solutions: they are becoming integral components of energy management systems, market design and grid stability strategies.
From assets to systems: the role of operational intelligence
As renewable portfolios expand and hybrid configurations become more common, the challenge extends beyond physical infrastructure. Value creation increasingly depends on how assets are coordinated, controlled, and optimized across technologies and geographies.
Modern renewable systems require:
- real-time alignment between generation, storage and demand
- rapid response to market signals and grid constraints
- minimization of curtailment and operational inefficiencies
- data-driven decision-making across entire portfolios
Fragmented operations and static control models struggle to perform under these conditions. By contrast, unified operational frameworks – combining monitoring, analytics, grid control and energy orchestration – allow assets to function as part of a coherent system rather than as isolated components.
This is where BaxEnergy’s Power Plant Controller (PPC) capabilities become essential. Operating as deterministic, real-time local control layers at the Point of Interconnection, they coordinate inverters, storage systems and plant-level assets under a single, grid-compliant logic.
By replacing static and vendor-specific control schemes with validated real-time execution, renewable plants (including hybrid solar, wind and BESS configurations) can behave as a single, predictable system under evolving grid conditions.
PPC-Core is part of BaxEnergy’s comprehensive solutions suite, which integrates Asset Performance Management (APM) systems, Computerized Maintenance Management Systems and Cybersecurity Solutions, ensuring operational excellence and resilience across multi-technology, multi-country portfolios.
From capacity expansion to operational excellence
The 2026 renewable energy landscape demands fundamental recalibration. Grid constraints, market volatility, and technology complexity have elevated asset performance management from back-office function to strategic differentiator.
Europe’s power system has entered a phase where scale is no longer the defining challenge. Renewable generation has reached structural relevance, reshaping electricity markets and grid dynamics across the continent. What now determines efficiency, resilience, and long-term sustainability is how this capacity is operated.
While plant-level control is a critical enabler, it represents only one layer of a broader operational ecosystem. Asset performance & maintenance management, grid control and cybersecurity must increasingly work together to address the full complexity of modern renewable systems – from single plants to multi-technology, multi-country portfolios.
As wind and solar continue to grow, the ability to orchestrate generation, storage and grid interaction becomes a decisive factor. Flexibility is no longer an optional enhancement; it is a prerequisite for system balance.
The next stage of Europe’s energy transition will be shaped by execution quality. Systems capable of managing renewable assets as part of an integrated operational framework will be best positioned to deliver stable, efficient and resilient power systems.
This is where the transition moves from ambition to performance.
