Warsaw MZA exercises option for further 79 Solaris electric buses, total to reach 158 by 2027

Solaris and Warsaw public transport operator MZA have expanded their last electric bus contract to a total of 158 battery-electric vehicles, with deliveries planned through 2027.

Miejskie Zakłady Autobusowe has exercised the contract extension option included in the agreement signed with Solaris Bus & Coach in September 2025. The original order covered 79 electric buses and has now been doubled through the addition of an identical batch, Solaris states.

The manufacturer says it has already delivered 163 electric buses to the Polish capital. At present, Solaris is executing several contracts for MZA, which together cover a total of 208 zero-emission Urbino electric buses, including the vehicles included in the extended Solaris MZA agreement.

Solaris MZA contract extension for Urbino electric buses

The extension of the Solaris MZA contract includes 50 articulated Urbino 18 electric buses and 29 standard 12-metre Urbino 12 electric buses. With this latest procurement step, the overall agreement now provides for the delivery of 158 zero-emission battery-electric buses to Warsaw’s municipal fleet.

The newly ordered vehicles will be produced according to the same technical specification as those included in the initial Solaris MZA order. The buses will be built without a traditional engine tower and will feature a modular drive system architecture, consistent with the configuration already selected by the Warsaw operator.

Solaris states that the 12-metre Urbino electric buses for MZA will be equipped with battery packs exceeding 500 kWh, while the articulated 18-metre versions will carry batteries with a capacity above 700 kWh. All vehicles covered by the Solaris MZA contract will be charged via plug-in connections.

Deliveries of the additional buses are scheduled for the first half of 2027, extending the delivery horizon of the Solaris MZA cooperation beyond the timeframe of the initial order signed in 2025.
