Power station life extension

I was recently told (and it makes a lot of sense I guess) that more than just one power station will be undergoing life extension work.

It's obvious really, not quite sure why I didn't see it.

The European large combustion plant directive requires either plants to shut down, or fit sulphur capture technology. Some plants are shutting, some are investing millions in fitting the sulphur capture technology.

Why would these plants (which are complying and fitting the technology) close?

It's obvious - they won't. Rather a bit of work will be done to keep them running for the next, well, who knows how long.
As far as I can see this means the following plants will have life extension work completed:

Installation	Installed capacity (MWe)	Number of boilers	Capacity opted in (MW)	Capacity opted out (MW)
Drax	3,960	6	3,960	0
Eggborough	2,000	4	2,000	0
Cottam	2,000	4	2,000	0
Ferrybridge	2,000	4	1,000	1,000
Fiddlers Ferry	2,000	4	2,000	0
Ratcliffe	2,000	4	2,000	0
Rugeley	1,000	2	1,000	0
West Burton	2,000	4	2,000	0
Longannet	2,304	4	2,304	0
Aberthaw	1,500	3	1,500	0
Kilroot	520	2	520	0
Uskmouth	393	3	393	0

This represents 65% of our current installed coal and oil generation capacity - the rest will close.

That's quite a bit then!
