Open Challenges from the energy corporate community of partners in SEE
Intelligent Congestion Management for Electricity Distribution Networks Challenge
As electricity grids become increasingly complex due to the integration of renewable energy sources, electric vehicles, and distributed energy sources (DERs), managing congestion in distribution networks has become a critical challenge for Distribution Operators.
Unified Data Integration Platform for Prosumers' Energy Flows
With the rapid growth of prosumers (clients who both consume and produce energy, often via solar PVs), energy supply companies are facing increasing difficulty in obtaining standardized, real-time energy flow data.
The lack of interoperability between diverse inverter models and platforms limits the visibility suppliers, DSOs, and TSOs have over distributed production and consumption patterns.
Tokenized Investment Platform for Renewable Energy Asset Co-Ownership
Energy transition requires massive investments in renewable assets such as solar parks, wind farms and battery storage (BESS).
At the same time, energy consumers are increasingly looking for ways to participate in the green transition beyond consumption.
This challenge seeks to create a digital platform that enables supply clients to co-invest in renewable projects, democratizing asset ownership and aligning customer engagement with sustainability goals.
Adaptive Optimization Algorithms for Urban EV Charging Networks
As electric mobility infrastructure expands in urban areas, operators face rising pressure to balance resource allocation, infrastructure deployment, and energy consumption all while maintaining cost-efficiency and high service availability.
This challenge aims to develop adaptive, data-driven algorithms for optimizing EV charger usage across city zones, using synthetic or anonymized datasets to model various deployment scenarios.
Digital Twin for Energy Production Facilities
We are interested in a Digital Twin solution primarily for predictive maintenance, and also for cybersecurity.
AI / AI agent solutions and integrated management platforms:
- Ensuring data governance, integrating multiple sources (ETL), analysis and reporting (Business Intelligence) – implement a platform that offers capabilities for Data Governance, Data Integration, ETL (Extract, Transform, Load), and Reporting.
- An AI Agent with LLM (Large Language Model) capabilities to streamline work with the large volume of documents (HR, Procurement, Engineering, Maintenance, etc.).
- An AI-based solution to assist with its Corrective Action Program (CAP) and Work Management (WM) processes.
- Automating processes in energy, natural gas, and nuclear storage facilities.
- Managing visitors and contractors in energy and nuclear facilities – a solution to automate the workflows for granting access to facilities, noting that these flows are specific and involve multiple steps and document types.
Use of drones and software platforms for automating the periodic and accidental inspection for industrial facilities and surveillance of overhead power lines.
Automating the inspection process of overhead power lines using drones and flight software in semi-automatic or automatic conditions (VLOS/BVLOS).
At the same time using Artificial Intelligence, collected data should be analysed and interpreted in order to identify defects.
AI forecasting of consumption and generation in low voltage networks
As the number of prosumers increases in the low voltage grid and consumption profiles change significantly based on weather the need for AI driven forecasting for day ahead regarding production and consumption becomes a critical challenge for Distribution Operators.
Next-Gen AI-based SecOps for energy infrastructure, covering both OT and IT environments
The solutions should reduce false alarms, decrease cyber data storage volume, and enable terabyte-scale analysis with reduced computing resources.
