Energy OS Podcast OverviewEpisode: Smart Metering, Connectivity and the Digital Spine of the Energy Transition

Guest: Manu Rawat

In this episode of Energy OS, We're joined by Manu Rawat, a technology leader with nearly three decades of experience across telecoms, IT, smart metering and critical digital infrastructure.

Together, they explore a part of the energy transition that is often overlooked: the physical and digital connectivity layer that allows the modern energy system to function.

Smart meters are too often described as devices in homes. But in reality, they are becoming something much more important: a national sensor network, a digital backbone, and a critical infrastructure layer for the future grid.

We discuss the evolution of smart metering from individual metering devices to an integrated infrastructure platform capable of supporting demand flexibility, renewable generation, consumer participation, data sharing and real-time system orchestration.

Drawing on our shared experience addressing transformation challenges across the UK smart metering network between 2020 and 2025, the conversation also looks outward to Europe. Manu shares insights from the European smart metering landscape, where interoperability, security, data access and market design are becoming central to the next phase of energy system digitisation.

The episode examines the tension at the heart of the future energy system: how to open up data, enable innovation and create fair competition while still protecting critical national infrastructure. This is not a simple technology problem. It is a systems problem, requiring collaboration between governments, regulators, networks, suppliers, technology providers and consumers.

At its core, this conversation is about reliability, resilience and leadership. Connectivity often disappears from view because it works most of the time. But as the energy system becomes more real-time, more distributed and more dependent on digital coordination, the connectivity layer becomes mission-critical.

The future grid will not be built on meters alone. It will be built on secure, resilient, interoperable infrastructure that allows millions of assets, homes, communities and markets to operate as part of a connected system.

Key themes covered in this episode include:

• Why smart meters should be understood as infrastructure, not just devices
• The role of connectivity as the digital spine of the energy transition
• How smart meters are evolving into a national sensor network
• Lessons from the UK smart metering programme
• What Europe can learn from UK deployment experience
• The balance between open data, innovation and security
• Why interoperability matters for future energy markets
• The leadership challenge of delivering technology at national scale

This episode is for anyone interested in the future of smart metering, digital energy infrastructure, critical national infrastructure, AI-enabled grids, flexibility markets and the practical reality of building the energy system we now depend on.

Because the energy transition is no longer just about generation.

It is about coordination.

And coordination depends on the digital spine being strong enough to carry the system.
