Devrim Celal– Kraken
In this episode of Leaders in Cleantech, David Hunt is joined once again by Devrim Celal, Chief Flexibility & Marketing Officer at Kraken, nearly six years after their first conversation in 2019—back when Devrim was CEO of Upside Energy.
Since then, Upside Energy was acquired by Octopus Energy and evolved into Kraken, now one of the world’s leading energy technology platforms, serving tens of millions of customers and optimising flexible power at global scale.
Rather than a linear success story, Devrim reflects on the last decade as a series of distinct phases: early uncertainty, pivotal strategic pivots, the acquisition decision, rapid scaling within Octopus, and now Kraken’s transition into a fully independent global company.
The conversation explores leadership at scale, the reality of building culture through growth, the trade-offs founders face between conviction and adaptability, and what the future holds for flexibility, storage, EVs, data centres and grid optimisation.
This is a thoughtful, honest discussion about long-term impact, not short-term hype—and what it really takes to build enduring companies in the energy transition.
Devrim Celal:
Devrim is the Chief Flexibility and Marketing Officer at Kraken. Overseeing Kraken’s flexibility and product capabilities, the cloud-based flexibility platform controls and optimizes distributed energy resources such as batteries of all sizes, EVs, solar and wind generation or heat pumps with machine learning and AI to match electricity supply and demand, helping the electricity grid deal with the natural volatility of renewable generation. Kraken is currently contracted to manage over 42 GW of power.
Previously, Devrim was the CEO of Upside Energy, which was acquired by Kraken in 2020. Before starting Upside Energy, Devrim’s professional career saw him take up executive roles with blue chip management consultancies and finance companies such as Publicis Sapient, Kearney and Lansdowne. He also holds an MBA from Yale University. In 2023, Devrim joined the Elexon Board, which manages the Balancing and Settlement Code of Great Britain’s energy system, as a Non-Executive Director.
