„From the Dark Side of Power to the Bright Side of the Energy Transition“—in this episode, Jan Christopher Klotz (CCO Germany at Zelestra) shares his journey from conventional energy into the world of renewables and what he has learned along the way.

The energy transition is entering its next phase. Expanding renewable energy alone is no longer enough. As solar capacity grows, the system is increasingly faced with an oversupply, which is reflected in negative market prices and a growing strain on the grid.

Drawing on practical project experience—ranging from large-scale PV and battery systems in Germany to global energy storage projects—Jan explains why the future lies in combining technologies: Generation requires storage, and individual installations must become integrated systems.

The most insightful finding, however, goes beyond technology. The energy transition is not just a technical challenge—it is a human one. Bringing together retailers, farmers, developers, regulators, and investors means reconciling different perspectives, languages, and incentives into a single, functioning system.

Tune in and find out why BESS will become the backbone of the next energy era and why real change will only happen when technology, systems, and people work in harmony with one another.
