Welcome to Season Ten of Conversations in Cleantech!
This season, we’re deconstructing digital infrastructure - one of the fastest-growing and most influential parts of the energy transition. From hyperscalers and AI demand to talent, capital, software and sustainability, we’ll explore how data infrastructure gets built, powered, financed, staffed and scaled.
In this episode, our hosts Joe Riley and Chloe England are joined by David Miller, Chief Commercial Officer at Gridmatic - an AI-powered energy company helping to optimise supply, demand and market participation across an increasingly complex grid.
As data centre demand accelerates and electricity systems face mounting pressure, the conversation explores how AI, storage and flexible load could reshape the way power is bought, balanced and delivered. Drawing on experience across energy consulting, grid-scale storage and energy trading, David shares how the grid is evolving from a one-way system into a far more dynamic network of generation, demand and real-time optimisation.
From the rise of controllable load resources to the growing role of battery storage and flexible demand, this episode unpacks how digital infrastructure and energy markets are becoming increasingly intertwined - and why smarter coordination may be just as important as new generation capacity.
For anyone interested in where energy software, AI and data centre growth collide, this is a conversation well worth your time.
02:05 - Introduction to David
02:38 - Could you walk us through your journey across energy consulting, the grid, large-scale storage, and AI-driven energy markets - and how it led you to Gridmatic?
05:16 - What was the defining moment that pulled you into the energy transition and the opportunity to make an impact at scale?
06:35 - Outside of work, what keeps you busy, and what are you passionate about?
07:01 - At Brightsmith, we talk about “living your purpose” - what does that mean to you personally?
08:06 - What do you do at Gridmatic?
11:56 - How do you define Gridmatic in the value chain - an energy company, a software company, or both?
13:38 - When you were scaling grid-scale energy storage at Wärtsilä, what were some of the biggest challenges you faced?
15:30 - How did moving to Shell and stepping into a global energy company change your perspective?
17:07 - What has been the most rewarding moment of your journey so far?
18:19 - Texas has strong momentum in the energy transition - do you see that continuing?
19:45 - As clean power and digital infrastructure increasingly overlap, what challenges are data centres creating for the grid today?
25:46 - Could you explain what controllable load resources are - and why they’ve become so relevant in today’s data centre boom?
26:34 - Looking ahead, what’s next for you, Gridmatic, and the broader energy system?
29:09 - What markets excite you most right now?
30:22 - What’s one piece of wisdom you’d share with others looking to build in this space?
