From UBITECH ENERGY team, we are pleased to share the latest developments on Task 4.4, regarding the EVELIXIA Autonomous District Decision Support Toolbox, part of Work Package 4 dedicated to Intelligent B2G (Building-to-Grid) and G2B (Grid-to-Building) Services. Led by UBITECH ENERGY, significant progress has been made, marking a critical milestone as we approach the halfway point of this task, with its completion scheduled for June 2026.
Task 4.4 Overview: Grid to Building services.
The objective of Task 4.4 is to develop a robust decision support system that seamlessly integrates the EVELIXIA District Digital Twin from Task 4.3, enhancing its capabilities through advanced optimization frameworks. This toolbox aims to empower grid stakeholders, including DSOs, energy aggregators, and retailers, by providing strategic insights and actionable recommendations for district-level investment decisions.
In recent months, collaboration has intensified through regular weekly meetings with our partners from CERTH, focusing specifically on enhancing functionalities within the integrated innovative solutions and EVELIXIA services. Several testing scenarios have been prepared and evaluated, facilitating the validation and refinement of the methodologies and tools involved. Moreover, successful offline data exchanges between the different integrated services have streamlined the workflow. The first version of the public deliverable D4.3, which encapsulates initial findings and methodologies, has been successfully submitted at the end of March 2025.
The Grid Investment Planning Assistant tool has demonstrated promising results in initial test-runs using a modified IEEE 33-bus test system reduced to a simplified 5-bus network. This assessment involved detailed load flow analyses, scenario comparisons, and robust financial evaluations employing Net Present Value (NPV) and Benefit-Cost Ratio (BCR) methodologies. The parametric analysis exploring variables such as discount rate and demand growth has provided valuable insights into investment viability.

The Multi-vector Network Manager tool has successfully tested its optimization capabilities for harnessing flexibility potential from distributed energy resources (DERs) and building operations. The framework, designed to minimize operational costs and curtailment of renewable energy sources (RES), effectively utilized linear programming to manage grid congestion. Pre- and post-optimization analyses validated the effectiveness of flexibility provision, demonstrating substantial benefits in grid congestion management.

Significant strides have been made with the Aggregated Demand Portfolio Manager tool. Utilizing advanced Reinforcement Learning techniques, this service efficiently aggregates and optimizes demand-side flexibility. By processing demand forecasts, flexibility bounds, DSO requests, and price signals, IS13 has generated practical recommendations ensuring both thermal comfort and cost efficiency, effectively identifying and managing periods without DSO requests.

Looking forward, immediate next steps include establishing structured data exchanges with the EVELIXIA Services Broker, and continuous refinement of the toolbox’s functionalities in line with EVELIXIA use cases and stakeholder feedback from DSOs and TSOs. We remain committed to keeping all stakeholders informed and involved as we advance in achieving our ambitious objectives.

UBITECH ENERGY participates at the kick-off meeting hosted by ETRA (September 25 & 26, 2024) in Valencia, Spain of the ECLIPSE Innovation Action, officially started on September 1st, 2024. The project is funded by the European Commission (Grant Agreement No. 101158494) and spans on the period September 2024 – August 2026. ECLIPSE main objective is the implementation and demonstration of the Common European Reference Framework (CERF) for energy consumers applications across the EU, enabling voluntary energy consumption reductions and load shifting, based on recommendations, strategies, and incentives, promoting sustainable energy consumption behaviour and empowerment of final consumers.
ECLIPSE project will define a set of rules and conditions for the development of new energy consumers applications and to improve of existing ones. These applications will provide to the final consumers with simple, useful and user-friendly information on energy savings, and broader benefits (such as a reduction in CO2 and other financial and social incentives) and at the same time reinforcing the stability and resilience of electricity grids, by means of consumer flexibility (e.g., through smart EV-charging, shifting heating loads, self-consumption, etc).
The project solutions will be deployed and demonstrated in 16 EU countries, being potentially replicated across the whole European Union, ensuring interoperability with third-party systems, while respecting the current regulatory framework and any existing competitive application offerings.
Within ECLIPSE, UBITECH ENERGY undertakes the preparation, coordination and monitoring of deployment and demonstration activities. In particular, UBITECH ENERGY will guide and monitor the deployment and demonstration activities in the 12 project pilot sites, while ensuring the timely implementation of the CERF developed, based on the requirements and use cases. Also, UBE will facilitate know-how exchange across the pilot sites and monitor the stakeholders’ active involvement at the ECLIPSE pilot sites.
