Rebuilding Mini-Grid Metering as Open Infrastructure - Joscha Winzer & Vivien Barnier, EnAccess Foundation

Wednesday October 7, 2026 16:50 - 17:10 CEST

Chamber Hall (Floor 3)

In the past 9 months, the two largest smart-metering providers serving rural mini-grids entered insolvency or severe distress, putting ~250,000 meters in 30+ countries at risk of losing billing, payment, and remote management, and threatening to leave over a million people, plus clinics and schools, in the dark. The cause was structural and familiar to anyone in open source: vertically integrated proprietary stacks, cloud lock-in, and no "supplier of last resort" for critical infrastructure.

This talk is a field report on the open-source response: an alliance of competitors, NGOs, and operators building an unbundled, multi-vendor platform on Digital Public Good principles. We cover the architecture (open APIs, multi-OEM interoperability, code and key release tied to bridge funding), the governance model for an asset that must outlive any single contributor, and how critical open infrastructure can be funded sustainably.

We close with concrete contribution paths: protocol work, hardware integrations (DLMS/COSEM, MQTT, STS), security review, and governance participation.
