ESG-Solar opens megawatt truck charging hub in Germany

Energiesysteme Groß (ESG-Solar) has recently commissioned a charging park for electric trucks in Niestetal near Kassel. The facility is located close to the A7 motorway and combines MCS charging technology with its own solar park and a battery storage system. Electric cars can also charge there. German solar developer ESG-Solar (Energiesysteme Groß), known as ESG-Solar, has opened a megawatt charging park for electric trucks in Niestetal, near Kassel in central Germany. The site is located close to Germany’s A7 motorway, one of Europe’s busiest north–south freight corridors, and combines megawatt charging with on-site renewable energy generation and battery storage. It is designed to supply heavy battery-electric trucks with charging power of up to 1,000kW. This makes it one of the first publicly accessible MCS-equipped truck charging sites in Germany. Construction of the facility began in December 2025. To ensure a reliable energy supply, Energiesysteme Groß operates its own solar park at the company’s industrial site. This solar park has a peak capacity of 2.1 MWp and is supported by a battery storage system with a capacity of 1,000 kWh for buffering. The battery enables solar energy generated during the day to be stored and used for truck charging during periods of higher demand or outside daylight hours. The charging park features three truck bays, each equipped with Alpitronic’s HYC1000 system. This system consists of a central power unit and three dispensers. Each dispenser provides both MCS charging with up to 1,000kW of power and CCS connections with up to 480kW. Unlike many motorway truck charging concepts that favour drive-through layouts, the charging bays require trucks to reverse out after charging. In addition, there are four HPC charging points for electric cars, which use Alpitronic’s Hypercharger units. A particularly attractive feature is the local charging price: all new contract customers can charge at Energiesysteme Groß for a fixed rate of 29.9 cents per kilowatt-hour until the end of 2026, the provider confirmed. The promotional tariff is thus significantly below typical public DC charging prices in Germany. ESG-Solar specialises in commercial-scale photovoltaic systems and ground-mounted solar parks across Germany. The charging park marks the company’s expansion into charging infrastructure for heavy-duty electric vehicles. “Electric mobility holds enormous economic potential, particularly in heavy-duty transport,” said Björn Groß, Managing Director of Energiesysteme Groß GmbH. He added: “By 2035, as much as 50 per cent of trucks could already be electric.” The company says the promotional tariff is intended to encourage logistics operators to accelerate the transition to battery-electric trucks. The project received funding from the German state of Hesse through its “Strom bewegt” (Electricity Moves) programme. The opening event included representatives from logistics, academia and regional government, with discussions focusing on the business case for battery-electric trucks and charging infrastructure. esg-solar.de (in German)
