Its actually a reasonable change. These vessels will have a minimum 30 year life...you can't be buying diesel now for that life when the other technology is in-service already in Kingston...the public wouldn't accept it and the politicians won't accept it, particularly in light of TransformTO.Yeah, I think this was a terrible decision. I'm all for electric in principle, but they moved to change design/tender mid-stream and it set back the purchase/delivery dates and inflated the costs. Its not, to my mind, the way we should manage the public purse.
The timing also makes sense...this vendor is developing a design that will then go to market for a shipyard to build, so its like moving a wall in your home renovation when its just the studs. The City went out with a public input process a number of years ago which concluded that people want the new ferries to have the look of the existing...this is not an off-the-shelf design taken from overseas, because that wouldn't be appropriate for the use case.
The hybrid ferries did not require charging infrastructure...their intent was that the diesel generators recharge the batteries while crossing, allowing no idle while dockside and reducing consumption. So the overall vessel design already could accommodate the weight of batteries...little to no change needed there. There is additional design for shoreside infrastructure (chargers, transformers, electrical infrastructure), plus manufacturing oversight, which I presume are what make up the change.
