Intersolar Europe 2025: ENGIE is shaping the energy transition with innovation, partnership and flexibility

Three days full of ideas, discussions and technologies: Intersolar Europe 2025 as part of Smarter E in Munich with more than 100.000 visitors once again confirmed its status as the world's leading trade fair for the solar industry - and ENGIE was right in the thick of it. With an international stand team from Germany, France, Poland and other countries, we showed how we, as an integrated energy provider, are actively shaping the transformation to a climate-neutral future.

The focus was on concrete solutions: scalable, economical and resilient. Our trade fair presence was characterised by innovative strength and a clear understanding of the requirements of our customers - whether project developers, local authorities or industrial companies.

Our topics at Intersolar 2025: From utility-scale solar systems to company roofs

The exchange with trade fair visitors centred primarily on:

• Projects and partnerships at European level
• Financing and construction of large ground-mounted photovoltaic systems and hybrid
  PV power plants
• Green Power Purchase Agreements (PPAs) and direct marketing
• Battery energy storage systems (BESS) as the key to flexibility and grid efficiency
• Onsite solar and Battery storage for C&I companies
• Sector coupling, digitalisation and new business models

It became particularly clear: Battery storage solutions are no longer just a technological addition, but a central pillar of future energy systems. The number of trade visitors with specific enquiries about storage systems was higher than ever before.

Benefits of bundling Onsite Solar PV with Battery Storage

Our Flexisun® model was once again present on our Engie booth. This solution developed by ENGIE LEI (Local Energy Infrastructures) activity enables C&I companies to maximize self-consumption of decarbonised energy, on average 20% higher than a photovoltaic installation alone, further reduce CO₂ emissions and electricity bills, and increase energy self-sufficiency and resilience with regard to the grid

ENGIE on stage: specialist presentations with relevance

Our expertise not only attracted a great deal of attention at our stand, but also in the conference programme at Intersolar 2025. Three of our colleagues shared their knowledge in high-calibre panels:

Research meets market: ENGIE Laborelec brings depth

Laborelec, the ENGIE Research and Innovation Centre, was also represented at Intersolar 2025. As part of the global ENGIE Research and Innovation Centre, Laborelec combines scientific depth with operational proximity. In Munich, discussions centred on battery storage, system integration and grid-friendly applications.

"We are taking a lot of ideas with us - especially on how technical excellence can be translated even better into marketable solutions," said Andreas Wabbes from Laborelec. The trade fair offered him and his colleagues plenty of opportunities to exchange ideas with industry partners and customers - and to actively help shape the energy transition.

Technological trends 2025: hybrid power plants, digitalisation, new business models

Intersolar 2025 has once again made it clear where the industry is heading:

• Hybrid power plants - i.e. the combination of different renewable energies with storage systems - are becoming the standard. They improve grid compatibility, reduce costs and increase security of supply.
• Sector coupling - in particular through the new Solar Peak Act 2025 - facilitates the economic use of storage systems, especially in times of negative electricity prices.
• Digitalisation - from energy management systems to intelligent direct marketing - enables more precise control and optimisation of renewable energies.
• Bifacial modules, transparent solar elements and building-integrated PV are becoming increasingly important - especially for urban applications.
   

The market figures also underpin the momentum: 655 GW of new PV capacity is expected to be installed worldwide in 2025 - another record figure. Germany remains one of the core markets, particularly for scalable solutions at industrial and municipal level.

ENGIE presented itself at Intersolar 2025 as a partner in a flexible energy future

Intersolar Europe 2025 has shown: The energy transition has long been a reality - but its realisation requires flexibility, partnership and innovation more than ever. ENGIE is strongly positioned in all these areas: from financing, engineering, construction and operation of complex systems to marketing.

We would like to thank all our partners, customers and colleagues for the intensive dialogue - and we are already looking forward to new projects and the next trade fair under the sign of the sun.
