The first unit has been handed over
Ireland’s National Transport Authority (NTA) has unveiled the first of an initial batch of 100 Alexander Dennis Enviro400ER plug-in hybrid buses, and has ordered a further 180 of these zero-emission capable buses for delivery in 2021.
The orders form part of a five-year framework agreement for a total of up to 600 Alexander Dennis Enviro400ER buses that was first announced in January 2020.
The plug-in hybrid bus to be deployed by NTA utilizes the BAE Systems Series-ER hybrid system with a 32kWh next-generation lithium-ion battery energy storage system that can be charged externally via a plug-in connection.
Plug-in hybrid buses for NTA in Dublin and Galway
Of the initial 100 vehicles, 74 will be operated by Dublin Bus in the Irish capital, and a further 26 will be operated by Bus Éireann in Galway, ADL points out. The first vehicles are expected to enter service in early 2021, and were presented to stakeholders and press at a ceremony in Dublin today.
The Enviro400ER is a double deck diesel-electric hybrid, capable of at least 2.5 kilometres continuous electric range with no exhaust emissions. It utilises the BAE Systems Series-ER hybrid system with a 32kWh next-generation lithium-ion battery energy storage system that can be charged externally via a plug-in connection, which means that the Enviro400ER is recognised as a ‘clean vehicle’ by the European Union’s Clean Vehicles Directive.
In addition to its continuous zero tailpipe emissions range within geofenced areas, the Enviro400ER switches off its diesel engine at low speeds during approach to and departure from stops and when stationary.
A Ventura Systems Plug Sliding door in the center enhances the interior space for passengers. In combination with a Ventura Inward Swinging door at the front, the flow of passengers at the lower and upper deck is optimized.
