ADL’s eyes are smiling after winning NTA Ireland framework contract

Ireland’s National Transport Authority (NTA) has ordered at least 100 ADL Enviro400ER double deck diesel-electric buses, capable of running in zero emission mode for at least 2.5km.

The single-supplier framework agreement, the result of a formal procurement process in which ADL (Alexander Dennis Ltd) provided the ‘most economically advantageous offer’ could extend to up to 600 units, and will run for up to five years.

The first 100 buses are to be delivered in autumn 2020.

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 lithium-ion battery energy storage system that can be charged externally via a plug-in connection, meeting the requirements of the European Union’s Clean Vehicles Directive.

In addition to its continuous zero tailpipe emissions range, the Enviro400ER switches off its diesel engine at low speeds during approach to and departure from stops and when stationary.

The buses will be 11.0 metres long and will have City style bodywork which has been adapted to suit requirements in the Republic of Ireland. The first 100 buses will seat 66 passengers and will have separate spaces for wheelchair users and passengers travelling with buggies. The framework agreement provides the opportunity to adjust the specifications of further vehicles to suit other operating requirements.
