Solar energy continues to strengthen its position as a central pillar of Europe's energy transition, driven by sustained deployment rates and increasing competitiveness across markets. Lower costs, policy support and accelerated permitting frameworks across several European Union Member States are reinforcing this structural clean energy growth. As the fastest-expanding renewable technology in the region, solar is reshaping the European power landscape, a trend highlighted at the international KEY 2026 exhibition organised by the Italian Exhibition Group (IEG).
Unprecedented growth and key metrics of European solar capacity
Accelerated deployment schedules over recent years have lifted solar power to record-breaking shares within the European electricity mix. Industry data confirms that solar has evolved into a mainstream foundation of the continent's decarbonised energy future.
- Achieving a new annual installation milestone: In 2025, the European Union installed approximately 65 GW of new solar PV capacity.
- Expanding cumulative installed capacity: The annual additions successfully pushed total cumulative installed solar capacity across the EU to over 330 GW.
- Substantial contributions to electricity generation: Solar generation accounted for around 13% of the EU's total electricity production over the course of 2025.
- Renewables surpassing fossil fuels: Working alongside wind energy, solar contributed to a historic milestone where the combined share of renewable generation surpassed fossil fuels for the first time in the EU electricity mix.
The strategic role of KEY 2026 in expanding clean tech investments
The KEY 2026 event delivered results that exceeded commercial expectations, acting as a vital catalyst for international energy collaboration. The exhibition provided a global hub where key technical and financial stakeholders could address the immediate challenges of scaling clean energy infrastructure.
- Securing project bankability: The event successfully brought together engineers, technology developers, investors and public institutions to formulate practical solutions for making renewable projects bankable.
- De-risking clean tech implementation: Central panel sessions focused on methods to accelerate physical project implementation timelines while mitigating early-stage financial and development risks.
- Demanding enhanced grid flexibility: Associations and industry representatives at the event strongly emphasized the urgent need to expand distribution grid flexibility to handle growing variable renewable generation.
- Establishing stable regulatory frameworks: Attendees highlighted the critical importance of transparent regulatory frameworks to maintain long-term market competitiveness and encourage continuous institutional investment.
- Planning for the 2027 edition: Following these strong baseline results, the next iteration of the exhibition is scheduled to take place from March 10th to 12th, 2027, at the Rimini Expo Centre.
Synchronized specialised exhibitions and the focus on PPA structures
The overarching clean energy ecosystem was further strengthened by specialized co-located events covering critical grid infrastructure and commercial power contract structures. These dedicated forums ensured that technological innovation was directly paired with transactional strategy.
- DPE - International Electricity Expo: Held in direct conjunction with KEY, this specialised event focused explicitly on the electrical generation, transmission, distribution, safety and system automation ecosystem.
- Cross-industry association collaboration: The DPE infrastructure expo was organised by the Italian Exhibition Group in partnership with the Distributed Generation Association (a confederate of ANIMA Confindustria) and Federazione ANIE.
- KEY CHOICE - Unlock the future of PPAs: Hosted at Rimini's Palacongressi Conference Centre, this targeted B2B event focused entirely on the evolving landscape of power purchase agreements (PPAs).
- Optimizing corporate energy procurement: Organised in collaboration with corporate consultancy Elemens, the PPA forum allowed large-scale industrial off-takers and developers to structure sophisticated risk-allocation mechanisms for long-term power delivery.
