“The need for reliable, cost-efficient and zero-emission mass transportation in Ostrava is perhaps higher than in other Czech cities,” said Daniel Morys, general director and board chairman of Dopravní podnik Ostrava a.s. “Clean air is an essential indicator of the quality of life. Therefore, I believe that passengers will appreciate our efforts towards a cleaner Ostrava and support us in the further expansion of electromobility.”
A Siemens microgrid control application will also be deployed to measure and transmit charging data to the transport operator’s systems for energy management as well as operations planning. This will allow remote and automatic control of the charging process according to the bus schedules, and it will be possible to change the charging output depending on the energy available. Siemens will also supply one 800 kVA and two 1,250 kVA dry type medium-voltage transformers to connect the charging points to the grid as well as medium-voltage switchgear, including a Siemens GIS, type 8DJH.
28 mobile chargers, each with an output of 22.5 kW, will be used for charging overnight or in a service garage, thus balancing the output and maintaining the eBus fleet operation. The Siemens delivery also includes project management, construction and assembly work, commissioning as well as preventive and corrective maintenance.
