It is a subsidy, in that this was free energy that renewables were unable to profit from, previously.

Before: The energy from a hydro plants gets wasted when it is night time.

After: Now they get money.

The hydro plant is now making money on something that they were just throwing away, previously, and thus it is a subsidy.

Hydro plants can usually turn off relatively quickly. They can be used as pump storage, which is an incredibly efficient way of storing energy - >70% efficiency [1].
