The European Commission has given cost estimates for CCS with low fuel costs at 7.5 to 9 cents per kilowatt hour in 2020 (this assumes oil at $61), whereas onshore wind is at 5.5 to 9 cents and nuclear at 4.5 to 8 cents. With high prices (oil at $100), nuclear is presumed to go up to the cost of wind; wind is unchanged, and CCS coal will cost 9.5 to 11 cents.

CCS would need some kind of technological breakthrough that makes it a lot cheaper, plus continued low fuel costs.

So, yes, it's basically a pure stalling tactic in order to build large, centralised, inefficient coal power plants now which we'll be stuck with for 50 years.

See the Guardian:

Protests by environmentalists over E.ON's plans to build a coal-fired power station at Kingsnorth have encouraged Ed Miliband, the secretary of state for energy and climate change, to rule that there should be no plants in the UK without some degree of CCS, with the remainder of any plant having CCS fitted within five years of it being judged "technically and economically proven".

A very tough and precise requirement on industry, that.
