Wallbox has announced the first real-world deployment of its Supernova PowerRing fast-charging system at Port de Sitges, a popular destination on Spain’s Mediterranean coast near Barcelona.
The project marks the first operational installation of the company’s Supernova PowerRing architecture, a new intelligent charging platform introduced in late 2025. Designed to optimize power distribution across multiple chargers, the system enables charging operators to expand fast-charging infrastructure more efficiently while maximizing available grid capacity.
The installation at Port de Sitges features three Supernova DC fast chargers connected through the PowerRing architecture. Once fully enabled, the system will support a shared dynamic charging capacity of up to 240 kW across the site.
Unlike conventional charging setups, Supernova PowerRing automatically distributes available power among connected chargers based on real-time demand. Depending on the number of vehicles charging simultaneously, vehicle compatibility, and available capacity, individual vehicles can receive charging power ranging from 80 kW to 240 kW.
Wallbox says the technology is designed to improve flexibility and efficiency while reducing the infrastructure challenges typically associated with high-power charging deployments. The system is capable of delivering up to 400 kW to a single vehicle when sufficient power is available and the vehicle supports the charging rate. Overall shared system capacity can scale up to 720 kW.
By dynamically allocating power where it is needed most, operators can improve charger utilization, reduce installation complexity, and lower the costs associated with expanding public charging networks.
“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 & Technology Officer and Co-founder of Wallbox. “PowerRing has been designed to help operators optimize available power, scale their charging networks and maintain a high-quality charging experience for users.”
The modular and compact design of Supernova PowerRing makes it suitable for a variety of locations where space and grid constraints are common. Potential applications include retail destinations, parking facilities, service stations, marinas, urban charging hubs, and other high-traffic sites.
The Port de Sitges installation is part of Wallbox’s broader rollout strategy for Supernova PowerRing across Europe as the company continues expanding its public and semi-public DC fast-charging portfolio.
As EV adoption accelerates across the continent, intelligent power-sharing technologies such as Supernova PowerRing could play an increasingly important role in helping charging operators deploy more capacity without requiring costly grid upgrades.
