The distribution network (including transformers etc) are all sized for maximum demand. Reduce maximum demand by storing it locally, then the size of the network (and the losses in it) are smaller too.Reduction of distribution costs, how? (Reduction of generation cost I could believe)
They don't of course - since your (and everyone elses) demand is what pulls the energy through the wires. But by supplying that demand from a local battery rather than across the grid at peak times, and then recharging the battery at off peak times cuts off times.Simon Mac said:Your "electricity company" some how hives off power just for your house, really?
Could be a slight problem trying to build some more Dinorwigs where I live in the Fens@BlackLeaf Interesting article.
I suspect we really need some more of these though: http://en.wikipedia.org/wiki/Dinorwig_Power_Station
More so as we push generation into unpredictable renewables.

As I said above I am a little rusty - so not up to date, but National Grid manage capacity by having contracts with generators that enable them to get them to increase generation at one place and decrease at another in order to try and avoid certain segments getting too warm. Most generation is connected at this level and there is a centrally run commercial market where generation can bid to vary their contracted demand on a close to real time basis. National Grid try to optimise on cost (subject to the physical constraints) using this market.
For sure, but my understanding was the backbone network has enough capacity, but local distribution and generation smoothing are the real problems faced.
Completely agree, pretty much all the "renewables" have this issue, so until we have solved storage we will continue to require almost as many power plants, just now they operate at suboptimal efficiency.Somewhere in the balance comes Wind Power which although quite cheap on windy days has that irritating property of providing nothing on others. Coupling large scale storage to wind generation could make wind power more attractive, and useful.
As for the quoted price, it is at pre-production stage, the point where every penny is added on by the accountants including the wages of the cleaners!. The real price only appears when the commercial package is marketed.
