ADL to deliver 600 hybrids for Ireland

Alexander Dennis Limited (ADL) has agreed to supply 600 Enviro400ER double-deck diesel-electric hybrid buses to the Republic of Ireland.

A framework agreement for the deal has been signed by the manufacturer and the Republic of Ireland’s National Transport Authority (NTA). The arrangement includes an initial firm order for 100 buses for delivery in autumn 2020. The single supplier framework agreement is scheduled to run for up to five years. The NTA will be able to exercise options for a further 500 vehicles to reflect vehicle requirements over the coming years. ADL was selected in a comprehensive procurement process in which the company provided the most economically advantageous offer.

The Enviro400ER hybrid utilises the BAE Systems Series-ER hybrid system with a 32kWh next-generation lithium-ion battery energy storage system. ADL says the vehicles are capable of running in zero emission mode for at least 2.5 kilometres. This 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 11m buses will have City style bodywork, 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.
