Ireland’s National Transport Authority has ordered 100 Enviro400ER double-deck plug-in hybrid buses and signed a framework agreement with Alexander Dennis for up to 500 more buses over the next five years. The Enviro400ERs are capable of running in zero emission mode for at least 2.5km.
The single supplier framework agreement covers the purchase of double deck diesel-electric hybrid buses and followed a comprehensive procurement process according to ADL. The first 100 buses are due 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 uses 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. The bus switches off its diesel engine at low speeds during approach to and departure from stops and when stationary.
The buses will be 11 metres long and will have City style bodywork which has been adapted to suit requirements in Ireland. The first 100 buses will seat 66 passengers and will have separate spaces for wheelchair users and passengers travelling with buggies.
“We are delighted to have been chosen by Ireland’s National Transport Authority for the supply of up to 600 clean buses,” says Alexander Dennis chief executive Colin Robertson. “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.”
