Pixii delivers robust, multi-megawatt Battery Energy Storage Systems (BESS) specifically designed for energy providers, telecom operators, and large commercial and industrial customers. Our modular technology ensures rapid deployment, high scalability, and reliability, enabling significant grid stability improvements, cost reductions, and revenue opportunities.
Flexible systems tailored for large-scale deployments
Our modular Pixii PowerBase XL and other scalable solutions are engineered for utility-grade storage applications. These systems can support extensive telecom networks, entire municipalities, and critical energy infrastructure, meeting demands that range from several hundred kilowatts up to multi-megawatt installations. Pixii’s proven track record demonstrates our ability to adapt and deliver at scale, ensuring long-term operational excellence.
Below are three selected examples demonstrating Pixii’s capability to deliver large-scale BESS projects:
1. Stadtwerke Hünfeld: strengthening grid resilience and profitability
As the oil and gas sector declines, municipal utilities are looking for new energy solutions to remain competitive and support local communities. Stadtwerke Hünfeld, a German municipal utility, took a strategic step by deploying a large-scale 6.4 MW / 21.6 MWh energy storage system from Pixii.
Highlights:
- Provides grid stability through Frequency Containment Reserve (FCR) and automatic Frequency Restoration Reserve (aFRR) services.
- Generates revenue from energy trading and flexibility markets.
- Offsets the phase-out of traditional oil and gas operations, creating new financial opportunities.
- Compensates for reactive power, solving a critical challenge for local grid operators.
This installation strengthens the stability and flexibility of the grid, and by reinvesting the revenues into public transportation, social initiatives, and essential services it also benefits the city’s residents.
2. Telecom resilience through large-scale storage in Germany
Telecom networks are vital to modern infrastructure, and ensuring their energy independence is becoming a priority. Energy costs, grid instability, and sustainability goals are driving telecom operators to seek battery storage solutions that reduce dependence on traditional energy sources. A major telecom operator in Germany adopted Pixii’s technology for a large-scale energy storage deployment:
Highlights:
- 15 PowerBase XL systems (135 cabinets) installed
- 4 MW of power & 24 MWh storage capacity
- Connected to 20kV AC via a Pixii-implemented transformer station
- Providing FCR services and imbalance energy trading to minimize high energy compensation costs
Technical Advantages:
- Advanced fire protection – individual fire compartments, redundant smoke detectors, and automated AC/DC disconnection
- Pure AC connection – no galvanic link between batteries, ensuring system reliability
- Highly modular & scalable – inverters and batteries integrated into each unit, allowing fast deployment with minimal infrastructure needs
This installation sets a new standard for telecom energy resilience, proving that battery energy storage is a key enabler for reducing energy costs, improving sustainability, and securing uninterrupted power for critical infrastructure.
3. GreenBat & Pixii: driving renewable integration in Slovakia
In Slovakia, Pixii collaborated with GreenBat to implement one of the country’s most advanced energy storage solutions. The project is designed to increase the use of renewables, balance the grid, and enhance energy trading efficiency.
Highlights:
- Supports the integration of renewable energy into the national grid.
- Enables energy arbitrage and peak shaving, reducing costs and increasing efficiency.
- Provides a flexible and scalable storage solution that adapts to changing energy demands.
This project represents a major step toward a cleaner, more efficient energy system in Slovakia, reinforcing Pixii’s role in leading the energy transition in Central Europe.
