Case study

Taming the sun with PV flexibility in Switzerland

As solar adoption accelerated across Switzerland, Romande Energie saw an opportunity rather than a problem. Together, we built a flexibility platform that aggregates and steers distributed PV in real time, turning decentralised assets into a reliable portfolio resource. What began as a focused pilot has evolved into a scalable solution, now rolling out to end consumers and laying the foundation for a more balanced, resilient energy system.
