The ebuses, provided by Larbert based vehicle manufacturer Alexander Dennis, are fitted with lithium iron phosphate batteries boasting a range of over 370km on a single, three-hour charge.
Glasgow’s Scotstoun depot now has 27 dual headed rapid charging points.
The delivery has been supported by Transport Scotland through its Scottish Zero Emission Bus funding, a challenge fund to support the industry’s transition to zero emission vehicles and infrastructure.
Transport Minister Fiona Hyslop MSP said: “Earlier this year we launched the second phase of the Scottish Zero Emission Bus Challenge Fund, with up to £58 million available, and it’s both exciting and encouraging to see the industry rising to the challenge and working with us to tackle the global climate emergency.”
More electric vehicles will also be joining First Bus’s operations further afield, with First Aberdeen depot expected to receive 24 new electric vehicles this summer.
