Not long ago my local council wanted to install 400 charge points for £4M.
Yes, you heard right.... £100,000 a socket.http://www.wigantoday.net/news/eco_car_ ... _1_1704807
So I guess this, by a private firm in a Wigan rooftop car park cost £200,000?http://www.grand-arcade.co.uk/news-item.asp?id=9
Must admit that does seem crazy money, although depending on what they are using and how they are installing them then the costs for public on street points is huge.
Just getting a Supply Authority connection can cost thousands and diggin the road up isnt cheap and then the intellegent posts arnt cheap on their own but then they need to comply with loads of safety issues etc plus all the back office to run the system again chews up the pennies.
Regarding the whole infrastructure side of things, the problem is its still very early days, think back to the early mobile phones, they cost massive amounts and the call charges where huge and you where locked into one network and even today while it is possible to roam between networks its not encouraged, although the phones and call charges have dropped considerabley.
Given time I can see there will be two systems, you will have the likes of Kevins Zero Carbon free charge points at hotels and pubs etc bit like the free wifi we find now, and then there will be pay versions in the high street and carparks which will be owned by several different operators and to start with there will be the whole issue, similar to the old mobile phone thing as to which operator do you join, the one with the more points in your area or the one with the country wide scheme etc, over time the whole thing will join up and end up almost becoming a PAYG type system I reckon, with you being able to "roam" between operators although if your not on your regular one you will end up having to pay a little more for the right to use it.
Thats how I see it going, but I am looking upwards of 10years or more into the future (you heard it hear first
