Europe’s energy future: eSIM as the confidence layer for a smarter grid

The energy landscape is moving fast, and utilities that treat connectivity as a core system capability, not an add on, will lead with reliability, data quality and AI ready insight.

eSIM is the confidence layer for that system. With the new IoT eSIM SGP.32 standard, shaped collaboratively with Kigen, eSIM becomes that confidence layer, enabling continuous and resilient service for AMI 2.0 collectors, DA controllers, C&I meter gateways and substation systems through storms, maintenance and rapid growth. Orchestrated by a certified eSIM IoT Manager (eIM), simple business policies (latency, loss, signal quality) trigger automatic, audited switchover, delivering network flexibility without truck rolls. The result is continuous service for AMI 2.0 collectors, DA controllers, C&I meter gateways and substation systems through storms, maintenance windows and rapid growth.

Standards aligned in-factory profile provisioning mean smart meters, gateways and controllers ship network-ready and stay governable for years. Secure device identity binds every data point to a known source; policy makes network flexibility practical – steering traffic between private LTE, public coverage and, where justified, satellite – without truck rolls. The result is uptime you can evidence and telemetry your operators and algorithms can trust.

We’re seeing this in the field. Collaborations with LCRA and Evergy, as well as device ecosystems led by innovators such as Itron and Iskraemeco, demonstrate how policy-driven eSIM transforms connectivity from a risk into a lever. Early results are sound, scalable and transformational. More deployments and breakthroughs are ahead and we’re excited to be part of the innovations happening in this space. The timing couldn’t be better. We are delivering what we said, in spite of all the curveballs.

For CEOs, the case is capital clarity: eSIM keeps options open across spectrum, suppliers and service models while protecting returns. For CIOs, it’s operational simplicity: one global SKU, zero-touch attach, lifecycle control at fleet scale. For CISOs, it’s verifiable assurance: hardware-rooted identity, better cybersecurity posture and defence-in-depth as standard practice.

What should leadership do next? Make eSIM a design decision in AMI 2.0, DER and distribution automation – not an afterthought. Insist on SGP.32 eIM and eSIM management and on in-factory profile provisioning so devices attach securely from day one.

Europe’s energy future demands confidence in the data that drives it. eSIM provides that confidence so your people can operate the grid you have today while building the grid you want tomorrow.
