DS4PED aims to transform cities into data-driven and sustainable urban environments by addressing key challenges in energy, mobility, and environmental planning through data space-enabled data sharing to achieve Positive Energy Districts in the cities of Rubí and Sofia.
The DS4PED pilot aims to empower public administrations to facilitate the following changes in their respective communities.
Cities can ensure that energy surpluses are distributed to those consumers who need it the most and when they need it the most. In the DS4PED pilot, tokens will be used during peak demand times or when solar production is low, ensuring that vehicle charging always uses renewable energy.
By digitalising and automating their energy management system with more and better data (enabled by a data space and digital twins), cities can save on the administrative (including legal, contractual) challenges of managing energy communities and supporting their journey to becoming financially-sustainable Positive Energy Districts.
By ensuring Proof of Renewable Energy Source guaranteeing energy users that their energy comes from renewable sources. The traceability solution that will be piloted would involve detailed tracking of the energy flow from solar generation to consumption, ensuring that electric vehicles are charged with 100% renewable energy. This solution can be scaled to other applications within the PED.
By integrating data from mobility, energy, and environmental sensors, the modelling and prediction of the impact on the urban environment will be performed, enabling targeted interventions for mitigation. By integrating climate projections, the project will assess long-term impacts, supporting climate-resilient urban planning.
DS4PED is being piloted in Rubí (Catalunya) and Sofia (Bulgaria)

The Rubí pilot powers EV chargers with solar energy and uses digital tokens to certify and share surplus solar power for use when needed. Real-time data sharing through the Empower-X data space ensures the energy is genuinely renewable and certification is automated. This supports affordable green energy access for public buildings and households at risk of energy poverty, enabling efficient, community-focused energy sharing to realise positive energy districts.

The Sofia pilot promotes sustainability and climate resilience via data-driven urban planning. It assesses solar potential on buildings with geospatial and energy data to boost renewables, while sharing mobility and environmental data analyzes air quality, traffic, and heat for greener designs. Multi-stakeholder collaboration targets congestion and pollution, with a unified platform enabling weather predictions and long-term climate projections.
