This is not quite correct. Your formula is for potential energy. To calculate the power generated by a hydro power turbine, you need to use flow rate (l/s) or mass rate (kg/s), and include head loss and turbine efficiency.

Also, 1 cubic meter of water has a mass of 1000kg, not 50,000kg

Yeah, I just wanted to go over energy rather than power since it's what is usually more important to the discussion. Another comment mentioned efficiency, so I didn't bother with it.

The 50k kg was definitely a mistake on my part. I tried editing it from 1k to 50k cubic meters in the example, but must have changed the wrong 1,000.
