The 1.2 MW megastatation from Ekoenergetyka-Polska has been delivered to Hamburg and the work on the commissioning of the entire infrastructure is in progress. The depot area is being gradually modernised so that soon the electricity from the powerful station will flow through the wires and power the first electric buses!

Megacontract – Megastation

Last year, Ekoenergetyka-Polska signed a contract with Verkehrsbetriebe Hamburg-Holstein, one of the largest public transport operators in Germany. The 8-year framework agreement provides for the delivery of a charging station for electric buses with a total capacity of more than 7 MW. The implementation of the charging infrastructure is one of the stages of an ambitious plan for the total electrification of the rolling stock in Hamburg by 2030.

Station transport

The first step in the implementation of this agreement was the production of 1.2 MW station. At the end of March we informed about the successful completion of internal tests of the charger. Then the station, which was enclosed in concrete casing and weighed almost 30 tons, was loaded with cranes and delivered by a special oversized transport to Hamburg.

Satellite connection

There, after it had been laid on foundations and assembly work, it was connected to the transformer station. Its power of 1.2 MW consists of 4 blocks with a power of 300 kW, each of which can charge 4 buses at the same time. In order to be able to load 16 buses at the same time, it was necessary to install and connect specially designed satellites. This stage has already been completed – 8 red distributors with the Ekoenergetyka-Posla logo already stand on the depot square in Hamburg.

Testing, acceptance and …  next deliveries

When the construction works at the depot are completed, the first tests of the operator’s electric bus chargers will be carried out. After passing the tests and technical acceptance, the station will be officially launched and the first buses powered by the infrastructure of the Polish manufacturer will go to the streets of Hamburg.

The delivery of further 1.2 MW megastations for Hamburg is planned for September 2019 and 2020.



We have completed another exceptional project. This time it is unique mainly because of its power and size. Successfully passed the tests of a charging station with a power of 1.2 MW! This giant can charge up to 16 electric buses at the same time! This is the largest station produced in the history of the company.

Megastation for Hamburg

This charging station was built for one of the largest public transport operators in Germany, Verkehrsbetriebe Hamburg-Holstein. This is the first of two blocks to be delivered to Hamburg in 2019.

Mega-casing made of concrete

Not only is the power of this charger unique, but also its casing. The power of 1.2 MW was enclosed in a concrete container, which was specially ordered and weighs almost 25,000 kg. And when the heart of the charging station is topped up with cables, contactors and power modules, it weighs almost 30,000 kg. The transport of this weight will therefore be a major logistical challenge, and powerful cranes will be required to unload it.

Mega-power – 1.2 MW

The 1.2 MW unit is divided into 4 modules with a capacity of 300 kW. To each of them are connected 2 satellites, each of which has two charging outputs. This means that the power of 300 kW can be distributed between 4 charging points and can power 4 buses at the same time.

Intelligent power management system

The infrastructure has an intelligent management system that allows you to make the most of its power. If two electric buses are connected to the station, 150 kW is transferred from the 300 kW module to each of them. When three vehicles are charged, two of them are powered by 75 kW and one by 150 kW. If 4 electric buses are connected at the same time, each bus receives 75 kW each.
