Belgium’s Société Régionale Wallonne du Transport (SRWT) has ordered Solaris buses powered by BAE Systems’ Series-E hybrid system, which is decribed by BAE as the Next-generation hybrid-electric technology powers buses.

As part of the company’s recent agreement with Solaris Bus & Coach S.A. of Poland to offer BAE’s electric drive systems on their hybrid buses, she has now expanded into Belgium, as Solaris has secured an order for more than 200 hybrid buses from Société Régionale Wallonne du Transport, the primary bus operator in Wallonia, Belgium. These buses will not only be the first Solaris buses to include hybrid systems for propulsion, but also the first buses to use the newest energy storage system, the ESS-3G-1K. The hybrid solutions’ energy storage system not only stores system-generated power but it also recaptures the bus operator’s braking energy for even greater efficiency. Then, only the stored energy is drawn upon to power the motor used for vehicle propulsion and to drive all other bus accessories, like air compressors, power steering, etc. This design allows operators to drive a bus on all-electric power since the motor drives the wheels using stored energy.

For Solaris, this order is its biggest success in Belgium, the BAE technology played a key role in the selection. The hybrid buses will be used by two bus operators: TEC Hainaut and TEC Liege-Verviers.
