Plug-in hybrid buses for Ireland. 100 ADL Enviro 400ER ordered

The Republic of Ireland will receive up to 600 double-decker plug-in hybrid buses ADL Enviro 400ER. A first firm order for 100 buses is already underway. The deal has been announced today by Alexander Dennis Limited, who will therefore deliver hundreds of Enviro400ER, capable of running in zero emission mode for at least 2.5 kilometres.

100 ADL Enviro 400ER to Ireland by autumn 2020

The framework agreement covers the purchase of double deck diesel-electric hybrid buses and will run for up to five years. ADL highlights the company 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.

Ireland BAE Systems powers the ADL Enviro 400ER

The ADL Enviro 400ER for Ireland 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 Series-ER system is highly reliable and an important step to full electrification for Ireland,” said Steve Trichka, vice president and general manager of Power & Propulsion Solutions at BAE Systems. “This technology gets Ireland closer to zero emission operations, reducing fuel consumption and improving air quality in the areas where its people live, work, and visit.”

Another feature of the BAE Systems Series-ER technology is that it allow the buses to drive on clean electric power through designated low and zero emission zones (as is the case of the 30 ADL vehicles for Brighton). The system uses global positioning software to enable the buses to run in full electric mode when they enter the zones. The buses switch to battery power when the engine is off – eliminating the release of exhaust emissions in populated areas such as near schools, hospitals, and tourist attractions.

66 passengers on the ADL Enviro 400ER for NTA

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, as ADL points out. 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.

Up to 600 ADL Enviro 400ER in Ireland

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.”
