Electric Vehicle Charging Infrastructure in Romania – Smart Solutions with Inowattio

Romania in the midst of an electric mobility transition

In recent years, Romania has entered a new stage in its energy transition: electric mobility. The number of registered electric vehicles has increased more than fivefold between 2019 and 2025. The streets of major cities such as Bucharest, Cluj, and Sibiu are now home to a growing number of zero-emission cars, while corporate interest in electric fleets continues to expand rapidly.

However, this growth brings a major challenge – the need for a modern, accessible, and intelligently connected charging infrastructure. Isolated charging points, lacking energy management or integration with balancing systems, are no longer sufficient. True value comes when these points become part of a digitalized energy ecosystem capable of optimizing energy flows, reducing losses, and ensuring stability for the national grid.

Why EV infrastructure is essential for a greener Romania

Electric vehicles represent more than just lower emissions – they offer an opportunity to redefine our relationship with energy. Each EV is a potential flexible consumer, able to charge when the grid has surplus energy and, in the near future, even feed energy back into it through the Vehicle-to-Grid (V2G) concept. For this mechanism to work, Romania needs an infrastructure that communicates in real time with grid operators and local storage systems.

Romania’s transition to a smart energy model has already begun. Funding programs such as AFM – Local Charging Station Grants and the Modernization Fund have accelerated the rollout of public infrastructure. Yet real efficiency emerges only when these systems are integrated with advanced energy management technologies like those developed by Inowattio.

From charging stations to a connected energy ecosystem

A modern charging station is no longer just a high-power socket – it is an interface between the grid, the user, and the energy source. Inowattio transforms these stations into an intelligent system capable of reacting to balancing signals, managing local solar energy, and optimizing charging times based on network availability.

Through its hybrid platform, combining cloud-native microservices with decentralized local control via IoT devices, Inowattio integrates every component of EV infrastructure into a unified ecosystem. The Nemesis device manages local power adjustments and communicates in real time with the central ARES system – an advanced SCADA platform fully compliant with Transelectrica’s requirements.

ARES receives and executes dispatch commands, while the Hemera module collects data every two seconds, analyzing the performance and stability of each connected unit. These data are then processed by Orion – the system responsible for slot management and ensuring that every charging point contributes effectively to grid balancing.

An integrated approach: public networks, companies, and prosumers

One of Inowattio’s greatest advantages is its versatility. The system can be deployed across public infrastructure – municipal networks, parking areas, shopping centers – as well as in private ecosystems such as corporate fleets, logistics hubs, or residential communities.

For local authorities, Inowattio enables the creation of interconnected charging networks managed from a single dashboard, providing detailed insights into consumption, renewable energy usage, and real-time station availability. For businesses, it ensures cost-efficient charging, automated scheduling, and seamless integration with self-produced solar energy.

Prosumers, on the other hand, become active participants in the energy ecosystem. Through the Inowattio mobile app, they can monitor charging status, set preferred intervals, and use locally produced solar power to charge their EVs. In this way, Inowattio delivers a complete experience – from energy production to consumption – within a single platform.

Security, resilience, and scalability

Modern energy infrastructure cannot exist without cybersecurity and reliability. Inowattio implements strict standards for data and communication protection, using encrypted protocols like TLS 1.3 and certificate-based authentication with X.509. Communication with Transelectrica through the IEC 60870-5-104 protocol is carried out via private VPN channels, ensuring data integrity and full control over power flows.

Additionally, the system includes automatic fallback mechanisms using LTE/5G connectivity, maintaining continuous operation even during network interruptions. Tests conducted by Inowattio’s engineering team demonstrated that the platform can manage over 22,000 active units simultaneously, with an average latency of under one second – clear proof of the robustness and scalability of its architecture.

Connecting to energy markets and the role of aggregation

A key feature of modern EV infrastructure is aggregation – the process of grouping multiple production and consumption units (such as charging stations and batteries) into a single entity that can participate in energy balancing markets. Inowattio has obtained technical validation from CNTEE Transelectrica for its aggregation solution, confirming full compatibility of its SCADA system and data flows with national energy market standards.

Through this functionality, EV infrastructure connected to Inowattio not only consumes energy but also contributes to grid stability. In the future, this model will enable participation in balancing services, allowing operators to monetize consumption flexibility – a critical step toward a decentralized, responsive energy economy.

The future: smart cities and autonomous grids

As electric mobility becomes the new standard, cities will need integrated infrastructure solutions. Inowattio aligns with this vision by developing technologies that connect electric transport, renewable generation, and local grids into a unified ecosystem. In a smart city, charging stations will communicate directly with solar panels, community batteries, and street lighting systems to ensure optimal use of every kilowatt produced.

In this context, Inowattio is not just a technology provider but a strategic partner in building a circular energy economy. Through its open and interoperable platform, the company supports the creation of local energy communities – a vital step toward energy independence and climate neutrality.

Conclusion

The transition to electric mobility is more than a shift in transportation – it’s an energy revolution. Romania has the opportunity to build an EV infrastructure that is intelligent, secure, and sustainable through Inowattio’s technological solutions. Whether for municipalities, corporations, or prosumers, everyone can become part of a connected, efficient, and environmentally friendly energy system.

Inowattio delivers the digital backbone for this transformation: an advanced SCADA platform, robust IoT devices, and a fully integrated ecosystem that works seamlessly with national grids. With a vision grounded in innovation and sustainability, Inowattio helps Romania take the decisive step toward a 100% electric future.
