In doing so, they relatively reduce the C02 price, thereby diminishing the advantage given by the instauration of the ETS to the lower carbon-emitting technologies among electricity production technologies from fossil fuels. This benefits the more emission-intensive technologies. There is at present nothing to "force" the fossil fuel producers to increase their output and keep total emissions constant. They might do so for economic reasons, but they might as well save allowances and sell them to other entities whose emissions are covered by the ETS - for example in other industrial sectors.
