The single supplier framework agreement covers the purchase of double deck diesel-electric hybrid buses and will run for up to five years. ADL was selected in a comprehensive procurement process in which the company provided the most economically advantageous offer. The first 100 buses have been firmly ordered and are to be delivered in autumn 2020 and the NTA will be able to exercise options for a further 500 vehicles to reflect vehicle requirements over the coming years.
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, 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.
Alexander Dennis Chief Executive Colin Robertson comments: “We are delighted to have been chosen by Ireland’s National Transport Authority for the supply of up to 600 clean buses. Our Enviro400ER electric range hybrid bus will reduce emissions and passengers will love the smooth journey experience, while drivers are bound to enjoy a great working environment in its spacious cab. This order confirms our strategy of leading the market with the widest range of low and zero emission buses, enabling us to offer the right vehicle for each requirement.”
