As electricity systems decarbonise, the nature of flexibility is fundamentally shifting. Where grid operators once relied on fossil fuel generation to follow demand, today’s energy systems are increasingly turning to the demand side for flexibility. With more electric vehicles, heat pumps, and behind-the-meter batteries connecting to the grid every day, the potential for distributed assets to support reliability and earn revenue, is rapidly growing.
But tapping into that flexibility at scale is no small task. It requires coordination, intelligent optimisation, and a clear route into energy markets. In this episode of Transmission, we explore how software platforms are making it possible to turn thousands of individual devices into aggregated resources that respond dynamically to grid needs. From flexibility markets and revenue stacking to the evolving role of energy suppliers and the economics of decentralised participation, this conversation breaks down how the grid is being rebalanced from the bottom up.
Quentin is Joined by Co-Founder & CEO of Axle Energy - Karl Bach. Over the conversation they cover:
- From load to resource: How electrification of heating, cooling, and transport is transforming grid demand into flexible capacity.
- Virtual power plants in action: What it takes to orchestrate hundreds of thousands of distributed devices across diverse asset classes.
- Consumer value meets system need: Why aligning grid requirements with consumer benefit is critical to unlocking participation.
- The platform model: How software intermediaries are enabling hardware providers and energy retailers to enter flexibility markets.
- Distributed flexibility as capex-light infrastructure: Why aggregating existing assets may offer faster returns than building new ones.
About our guest:
Karl Bach is the co-founder and CEO of Axle Energy, a platform that enables distributed energy assets - from EVs and heat pumps to residential batteries, to participate in electricity and flexibility markets. With over a gigawatt of connected capacity, Axle works behind the scenes to optimise assets and unlock value for hardware providers, energy suppliers, and the grid. Karl brings a systems-level perspective to the conversation, shaped by experience at the intersection of energy markets, technology, and scalable software infrastructure.
