No, it couldn't. Drax is dispatchable, a tidal scheme isn't.

OMFG do you actually read posts ? apparantly NOT with your !!!!!!!! cherry picked comment.

the ENTIRE line which you cherry picked is

5% means it could replace Drax (well in theory as the barrage would provide power at peak times for the tide

see the last part? PEAK POWER FOR THE TIDE

!!!! me - how stupid can you get.

I think you very well demonstrrate the absolute limit of stupidity a human being can achieve, so you have answered your own question.

For sane people, I can assure everybody that Drax connot be replaced by any tidal scheme however powerful. When Drax is decommisioned it will have to be replaced with dispatchable generation.

been quite quiet last day or so...

I see graham is back

stupid as in can't spell?

and anyone that can comprehend (or spell) can see , from my own post , especially since i wrote it - that whilst a tidal barrage could produce 5% or similar to drax, as i clearly put - it would be at PEAK POWER with the tide

apparantly though , your stupid enough not to understand english - or spell properly either.....

Hi

It's likely that your popcorn will go stale then ....

Graham is correct ..... without the ability to store the tidal energy when it must simply be pumped into the grid when generated. The Severn barrage system is not a continuous baseload provider (such as nuclear) and, as Graham has mooted, it's not a dispatchable generating source (coal/gas/hydro) either, it's also not an intermittent generating source (wind/pv) .... it's a schedulable regular source, that is, the generation of power from dispatchable sources such as coal, gas & hydro can be scheduled to be reduced at times when the barrage is scheduled to be providing power .... CO2 saved, capacity duplicated .....

There are a number of possible ways around that issue, however, the muted 'lagoon' barrage system would be quite limited in scope and capacity due to the relative elevation of the water levels, the only really likely solution would be to vastly increase the UK pumped storage capacity by flooding a good proportion of the high valleys in Wales .... (sorry Martyn, I know they're on your doorstep .. ) .... Norwegan pumped storage ?, well you'd need to talk to another country on that as they have Hydro, but not much to spare in dry years and the important thing is that there's no/not much pumped Hydro so it'll need them/us to invest heavily ... best put it in Wales then, sorry Martyn, but it could be quite good for the economy if you go for independence too ...

Well what I read (in English, not english) was

5% means it could replace Drax (well in theory as the barrage would provide power at peak times for the tide).

Which is garbage I'm afraid, for the reasons I have already given.

As to stupidity, well it's well recoginsed by (almost) everyone that abuse is initiated by the intellectually challenged.

Hi

... although it's not what you wrote, which was "5% means it could replace Drax (well in theory as the barrage would provide power at peak times for the tide)" .... this is not "similar to" and was not clearly put, although it's likely what was meant ....

Graham was correct regarding generation , Graham is correct regarding generation ..... and if you fail to understand this, then I'm afraid that he may also be correct on other things too ....

Hi


Graham is correct ..... Z

My word Z, you're a much braver man than me! (unless you like running the risk of being attacked by a pack of salivating demented rottweilers).


Regarding pumped storage, there are very few places where it's even possible to build more stations (in England and Wales). There are several in Scotland and probably plenty of suitable topography, but with the N-S tranmission lines usually at capacity, the grid couldn't import more generation from there at peak times even if it wanted.

Dinorwig wasn't built to store enery at cheap times and release it at peak times (as Wiki will probably tell you). It was designed to supply reserve for frequency support. When the probability of its reserve capacity being called upon reduces during the day, and it's potential generation is sufficiently cheaper than competing generation, then Dinorwig will release it's energy, usually around the peak. It appears to store cheap energy and sell it at peak times, but that is very much it's secondary purpose after its primary reserve duty.

fail to see why you wasted your time typing all that in response to what i said.....

whatever floats your boat i guess
