Can traditional power stations be switched on and off at will?

No, they can't, they have to be powered up and down over several hours - especially nuclear power stations. This is why hydroelectric power stations are so useful to deal with surges in power demand, they can go from zero to full in seconds - Dinorwig Hydroelectric powerstation is the fastest, taking 12 seconds to go from 0 - 1,320 mw.


Why does tidal power stations cost more than hydroelectric power stations?

Tidal power stations require specialized technology to capture energy from changing tides, which is still in the early stages of development and more expensive to build and maintain compared to traditional hydroelectric power stations. Additionally, tidal power stations face more technical challenges due to the harsh marine environment, increasing their construction and operation costs.
