Most of the subsidies have been cut (which is why the install rate of solar power stations has plummetted), and the money paid is not all a subsidy (to start with, the government doesn't pays it and the taxpayers money is not touched). In spain solar and wind power is 0 in the "power market", and the power distribution companies have to pay solar and wind energy at a prices the government has set. If there was a free market there wouldn't be any price set by the government, but the owners of solar and wind power stations would ask for a higher price than 0. There would be certainly a difference between the current price and the theorical free-market price, but some people think that the current price is all of it a subsidy, which it isn't (we just don't know how much of it is a subsidy). But that doesn't really matters, renewables are stil progressing. The proof is that despide of the lack of strong subsidies some companies are still planning new installations. Elecnor announced recently 3 new solar stations of 50 MW each one that will cost 900 millions - from their pocket. They wouldn't risk that money if they feared that the pro-nuclear opposition party can ruin it with a policy change.
Oh, and the nuclear power stations that have been dismantled in the last 20 years weren't really dismantled because of a anti-nuclear policy. The real problem was that those nuclear stations weren't needed (3 of our 8 nuclear power stations are switched off right now, and we are still exporting power to other countries) and some power companys went bankrupt while constructing them. The government had to use taxpayers money (lots of them) to keep those private companies alive, and had to stop the construction of new stations to avoid more losses. The best way the government found to hide all that was to tell the media that they had decided to go green.
