How much does hydroelectricity cost to generate?

In terms of £/Mwh when compared to coal and other forms of electricity generation. I assume pretty low as there is no fuel cost involved, but I'd appreciate if someone could give me a rough estimate.

The US spends 85 cents per KwH, so $850 per MwH. That's about £600.
