Wallbox has completed the first commercial deployment of its Supernova PowerRing fast-charging system, installing the technology at Port de Sitges on Spain’s Mediterranean coast.
The project marks the first real-world application of the company’s PowerRing architecture, which was introduced in late 2025 and is designed to dynamically distribute power across multiple fast chargers from a shared energy source.
First Deployment at Port de Sitges
The installation consists of three Supernova DC fast chargers connected through the PowerRing system.
At the Port de Sitges site, the chargers share a combined available power capacity of up to 240 kW, with the system automatically allocating energy based on the number of connected vehicles and their charging requirements.
Wallbox said individual chargers can deliver between 80 kW and 240 kW depending on vehicle compatibility and site demand.
The broader PowerRing architecture is designed to support shared power capacities of up to 720 kW and can provide up to 400 kW to a single vehicle when sufficient capacity is available.
Designed for Flexible Infrastructure Deployment
According to Wallbox, the system is intended to help charging operators maximize the use of available grid connections while simplifying network expansion.
The modular architecture allows operators to add charging capacity without requiring equivalent increases in grid infrastructure, which can be a challenge in locations with limited electrical capacity.
“This first deployment is an important milestone for Supernova PowerRing and demonstrates how this technology can help operators deploy fast-charging infrastructure in a more efficient and flexible way,” said Eduard Castañeda, chief product and technology officer and co-founder of Wallbox.
“PowerRing has been designed to help operators optimise available power, scale their charging networks and maintain a high-quality charging experience for users.”
Targeting Diverse Charging Locations
Wallbox said the Supernova PowerRing system is suitable for a variety of charging environments, including retail destinations, parking facilities, service stations, marinas, and urban charging hubs.
The company identified limited space and constrained grid access as two of the primary challenges facing charging infrastructure deployment in these locations.
By dynamically allocating power where it is needed, the system aims to improve charger utilization while supporting future network growth.
European Rollout Underway
The Port de Sitges installation forms part of Wallbox’s broader plan to deploy the Supernova PowerRing platform across European markets.
The company said the technology is intended to support the growing demand for high-power charging infrastructure as electric vehicle adoption continues to increase across the region.
The rollout comes as charging providers seek solutions that balance charging performance with grid capacity limitations and installation costs.
