Digital Energy 40 report

Europe’s clean power capacity is growing fast, but our energy systems are under pressure. From rising grid complexity to decarbonisation deadlines, the challenge isn’t just building more renewables, it’s making the system smarter, more flexible, and more resilient.

The Digital Energy 40 showcases the organizations solving that problem with code. Spanning the UK, DACH, and Nordics, it highlights 40 standout companies — from agile startups to industry giants — that are using digital tools to deliver real-world energy transformation.

Each company was evaluated across four pillars:

• Market Execution – Ability to scale in real-world conditions
• Market Innovation – Novel business models and engagement strategies
• Technology Capability – Depth and sophistication of digital solutions
• Technology Impact – Measurable progress on clean energy outcomes

This year’s ranking reveals how digitalisation is reshaping every layer of the energy system. Some of the most dominant themes across the Digital Energy 40 include:

• Energy Flexibility and VPPs – Smart coordination of distributed assets like EVs, home batteries, and building systems
• AI as Infrastructure – Embedded across the stack, from grid optimisation to pricing and forecasting
• Battery Intelligence – Companies are using digital models to improve battery health, safety, and lifespan
• Customer-Centric Platforms – App-led smart interfaces that connect pricing, automation, and user control
• Interoperability & APIs – Open systems are replacing legacy tech. Many companies are building platforms designed to plug in, not lock down

These trends show a clear direction of travel: a more adaptive, data-driven energy ecosystem where software is just as critical as hardware.

Why now?

Europe’s clean energy systems are under pressure — and digitalisation is the only path forward. From virtual power plants to AI-optimised storage, software-led innovation is reshaping how energy is managed. The Digital Energy 40 cuts through the noise, spotlighting the companies, platforms and people leading that change.
