The Digital Backbone of Energy Storage Optimization with Roger Hollies (Arenko)
Transmission
Outro
Ed and Roger close the episode, summarize key points, and thank listeners.
Batteries are no longer just shifting energy from one time of day to another - they’re becoming critical grid infrastructure. But to unlock their full potential, we need smarter ways to manage billions of data points in real time, so storage can deliver everything from peak shaving to power quality and grid support and keep them operating safely, efficiently, and optimally.
In this conversation, Ed is joined by Roger Hollies, Chief Technical Officer at Arenko. Over the conversation, they discuss how market governance needs to evolve, why it’s time to crack open the ‘black box’ of automated trading, and how ‘rules as code’ could be the key to unlocking a cleaner, cheaper energy future.
Key topics discussed:
- How software can make ultra-complex battery assets manageable.
- Why batteries are overtaking fossil fuels in essential grid roles like frequency response, voltage control, and inertia.
- The data infrastructure required to handle seven billion datapoints a day across global energy portfolios.
- How open-source, “rules as code” market design could speed up innovation.
- What must regulators do to enforce fair markets and guarantee top-tier service delivery.
