Morphology

megawatt = watt (transparent) = mega + watt

The meaning is directly compositional: 'mega-' means one million and 'watt' is a unit of power, so the whole word means one million watts.

Etymology

The word megawatt comes from the prefix mega-, meaning 'large' or 'a million', and watt, the unit of power named after engineer James Watt. So a megawatt is 'a million watts', which is why we use it to say how much power a plant or city can produce or needs.
