EMPOWER-X in DS4PED Rubí: trusted energy data for renewable EV charging

Paco Conde, Co-Founder & Jose David Doria, Chief Operations Officer & Gio Dal Mas, Project Manager at Zertifier, Catalonia Energy data spaces become relevant when they help cities solve operational problems. EMPOWER-X, recently recognised as a Gaia-X Lighthouse Ecosystem, applies this approach to the DS4PED pilot in Rubí, where trusted data sharing is used to certify renewable energy use in electric mobility and support the deployment of Positive Energy Districts. The Rubí pilot therefore links municipal PV production, EV charging consumption, smartmeter data and mobility services through a traceability layer that can verify the renewable origin of charging events. The marketplace and data services layer, supported by Ocean Enterprise Collective, enables publication, discovery and controlled use of datasets, algorithms and Compute-toData services. This is important for public infrastructure, where EMPOWER-X in DS4PED Rubí: trusted energy data for renewable EV charging IMAGE 1- DS4PED Rubí energy traceability dashboard: certified renewable energy, surplus solar production, EV charging consumption and hourly solar/grid contribution.
