Lothian are to introduce 20 new electric-hybrids by 2017 and they will carry a similar livery to the Volvo 7900 Hybrids. I'm not sure how publicly known it is which route is being upgraded, so I'll keep schtum for now.
When at a terminus, they will be 'plugged in' to charge the bus for the journey to the next terminus. There has been a few instances over the last week whereby the demonstration vehicle which Malarkey pictured broke down owing to the failure of one of the batteries, meaning it had to be towed back to the depot.
It is merely a prototype model, so the Volvo representative would not disclose information to me regarding the vehicle and infrastructure price.
The batteries would of failed due their being no Infrastructure in place in Edinburgh to therefore charge these Vehicles up, these Volvos along with the 20 7900s for Service 30 due in 2017, require a Pantograph which attaches to the Conductors in the Roof of the Vehicle at the Services Terminus to therefore charge the Batteries up, iirc there should be a 4 Page Article in the "New Technology in Buses" Thread, which I uploaded regarding the Volvo Electricity which provides more information on this Vehicle.
