Energy Capacity

On-Grid Power

The customer, a cable-car operator in Austria, faced challenges managing dynamic energy demand. Running the cable car requires substantial power and drove high electricity bills. The BESS acts as the “muscles” of the system — storing excess energy from the site's PV panels and deploying it when needed. Because the cable car's demand changes rapidly and unexpectedly, the BESS's fast response keeps it running smoothly, cuts grid reliance and lowers electricity costs.

Synecotec project, Austria

The Site

Challenges & Solutions.

The key challenge was installing the battery storage system at an altitude of 1,500 metres, inside the former cable-car operations building. The remote location and the difficulty of transporting and positioning the equipment at that height created significant logistical demands.

The battery energy system integrates two units into a virtual block to boost efficiency. It provides peak shaving, stabilises the power supply and manages consumption beyond grid limits. It stores excess PV energy to avoid grid exports and uses time-shifting to optimise storage, and enables price arbitrage by discharging during favourable market rates. Future plans focus on reducing the CO₂ footprint in line with sustainability goals.

On-Grid Power

A plastics factory in Bulgaria with a 300 kWp rooftop solar installation was not using all of its generated solar energy. When production did not consume everything generated, the surplus fed into the grid at rates that did not justify the solar investment. Integrating a battery storage system resolves this by capturing excess energy to maximise PV yield.

5 600 kW

On-Grid Power

A battery energy storage system that collaborates with the plant's turbines to provide ancillary services for grid stability (aFRR ±) and black-start backup. Without the battery, operations would be technically limited in the services provided and economically disadvantageous due to the high fluctuations in turbine operation.

VEOLIA project, Slovakia

The Site

Challenges & Solutions.

The battery storage system was deliberately over-dimensioned to guarantee the energy needed to smooth deviations in the designated services with the smallest possible capacity, while accounting for capacity degradation over time to secure long-term service delivery. During implementation, the challenge was integrating the whole system into a complex gas power plant without compromising its operation — building a new connection and substation for the local grid and developing a solution for seamless cooperation with the plant-wide microgrid SCADA system.

On-Grid Power

Ferlach 1 is a 2 MW / 5.6 MWh battery storage system near Ferlach in southern Austria, built by Volthein to expand its presence in Central Europe. It strengthens grid stability and supports Austria's shift to renewables by responding quickly to power fluctuations and automatically restoring grid balance. It also optimises energy use through price arbitrage — storing electricity when it is abundant and releasing it during peak demand, reducing the need for conventional generation.

Ferlach project, Austria

The Site

Challenges & Solutions.

The project presented a unique engineering challenge: installing heavy battery and inverter hardware into a pre-determined space within an existing EV charging facility for caravans. Roof-construction limits meant that positioning the heavy technology safely required precise team coordination to protect both the building structure and the equipment.
