Plug-In Asset for Grid Congestion
Management
Ores/Resa Challenge #2
The Challenge
The LV distribution grid is under pressure. Overvoltages from PV injection and undervoltages during peak demand (e.g. EV charging at dinner time) are leading to localized congestion. We need plug-and-play hardware to solve these issues quickly and cost-effectively, without major infrastructure overhauls.
What we're looking for
-
A modular, low-cost device that helps mitigate voltage issues (over or under) in real-world grid conditions.
-
Can be deployed quickly in residential streets or SME zones with minimal installation.
-
A solution that can operate autonomously or be remotely monitored and controlled.
-
Experience with low-voltage grid equipment.
Must-haves​
-
Proof of concept available (TRL 6–9).
-
Meets safety and electrical compliance standards.
-
Suitable for installation by grid operators.
-
Remote control and monitoring functionality.
Nice to have
-
Built-in data access and visualization features.
-
Modular design for scalable or future-proof deployment.
-
Too large, heavy, or costly for residential deployment.
Not a fit
-
Requires long setup or integration time.
-
Pure hardware vendors without grid context.
Ideal Applicants
-
Technical providers focused on hardware-grid interface.
-
European-based startups or SMEs with validated pilots.
-
Providers who understand utility procurement and DSO usage constraints.
What Succes looks like
ORES/RESA can deploy a compact asset to stabilize voltage fluctuations at local grid hotspots - reducing outages, complaints, and infrastructure stress with minimal cost and downtime.
The Challengers
As Wallonia's leading distribution network operator, ORES ensures that some key necessities are available for everyone: electricity, natural gas, municipal street lighting, every day, 24 hours a day, seven days a week. Delivering local public services, ORES meets the expectations of households, businesses and local public structures in 75% of Wallonia's communes, whether in terms of quality, accessibility and speed of service. Last but not least, ORES is fully committed to driving the ongoing energy transition by fostering innovation, sustainability, and a resilient energy future.
Resa is the main distribution system operator for electricity and gas in the Belgian province of Liège. The company owns, develops, operates, and maintains medium- and low-voltage electricity networks, as well as medium- and low-pressure gas distribution networks. Its mission also includes responsibility for the development, long-term reliability, and safety of these networks. In addition, Resa manages public lighting and fulfills certain public service obligations.
