IN Brief:
- NGEN Group is building around 1.25GWh of battery capacity across the European Union.
- Its SG Brain platform uses AI to manage generation, storage, consumption, market signals, and renewable output.
- The model reflects the shift toward software-controlled storage, grid services, smart meters, and EV charging infrastructure management.
NGEN Group is expanding battery systems and AI-based energy management across Europe, with approximately 1.25GWh of battery capacity under construction in the European Union.
The Slovenia-based company presented its battery and smart energy platform at Belgrade Energy Forum 2026, positioning storage, software, and digital control as core components of a decentralised electricity system. Founded in Žirovnica in 2018, NGEN now operates across 11 European countries and employs around 200 people.
NGEN built its first battery storage facility in 2019, with 12.5MW of operating capacity and 22MWh of storage. Since then, it has developed systems covering battery energy storage, hybrid inverters, smart meters, and electric vehicle charging infrastructure management. Its battery systems range from smaller installations to assets above 200MW.
The company’s platform model combines hardware, software, installation, system management, and market access. Its key products include the G-MAX battery system and SG Brain, an artificial intelligence platform integrated into the SG Connect energy management system.
SG Brain is designed to manage generation, storage, and consumption in real time. It processes weather forecasts, electricity prices, consumption profiles, and solar and wind generation data, then uses those inputs to determine battery charging, discharging, grid application activation, and renewable optimisation. The system is designed to operate autonomously as market and system conditions change.
That type of control architecture is becoming more valuable as storage moves beyond standalone balancing. Batteries increasingly sit within wider energy systems that include renewable generation, grid constraints, market access, EV charging, building demand, and smart metering. The value of the battery depends not only on cell chemistry and inverter capacity, but also on dispatch logic, communications, cybersecurity, data quality, and market integration.
The UK’s MW Dispatch service shows the same shift toward active operation of distributed assets, allowing distribution-connected generators and batteries to help manage transmission constraints. NGEN’s platform sits in a broader European market where smaller, distributed, and grid-scale assets are being drawn into more active system control.
Battery economics are becoming more layered as markets mature. Assets must respond to wholesale prices, imbalance exposure, ancillary services, congestion, curtailment, and local network conditions. A static charge-discharge profile is poorly suited to a market where power prices, constraint values, and system needs can change quickly.
Financing and procurement are moving in the same direction. The 297MW UK BESS pipeline funded by Gresham House includes battery, inverter, and medium-voltage transformer procurement across multiple sites. As storage projects scale, the performance gap between assets will increasingly be shaped by control software, market access, and operational responsiveness.
Cybersecurity and compliance are now part of that operating foundation. Platforms that control generation, consumption, storage, and market participation become part of the grid’s digital fabric. They must protect data, maintain availability, and operate within regulatory frameworks, particularly where assets provide services that affect system stability.
EV charging infrastructure adds further complexity. Charging demand can be flexible, but it is constrained by vehicle availability, depot schedules, driver requirements, and site connection limits. Combining battery storage, smart charging, forecasting, and market signals creates a route to manage charging loads while reducing peak import and improving site utilisation.
NGEN’s expansion points to a storage market in which software is no longer a secondary feature. Batteries are becoming controllable grid assets, and their value depends increasingly on how effectively they interpret data, respond to market conditions, and operate across multiple applications without compromising reliability.
