Solar can be switched off at a moments notice. Power from windturbines can also be controlled. So an excess amount of renewables is not a big issue for the grid. Owners of renewable sources may be less happy to switch them off. (In the EU) storage can take the place of fossil when fossil becomes expensive enough. No need to give more subsidies to storage than renewables would get. Excess amounts of renewable can also be used for other purposes, such as producing green hydrogen.
