The double-deck StreetDeck Electroliner battery electric vehicles (BEV) will be operating on Routes 297 and 142, which drive through the boroughs of Brent and Ealing, and Hertfordshire (Watford), Harrow and Barnet.
The new buses will be built in Northern Ireland at the Wrightbus facility in Ballymena.
Ian Foster, group engineering director at Metroline, said: “Our testing of the new electric vehicle has shown an excellent level of power usage per mile, and we are confident that, working closely with the development team at Wrightbus, these figures will continue to improve.
“As with the hydrogen bus order, it is essential that wherever possible we purchase vehicles with a high local build content, supporting the UK supply chain backing our own technical expertise in the zero-emissions arena.”
