  Citing measurements made at the 1926 Iowa State Fair, they reported that the peak power over a few seconds has been measured to be as high as 14.88 hp (11.10 kW)[12] and also observed that for sustained activity, a work rate of about 1 hp (0.75 kW) per horse is consistent with agricultural advice from both the 19th and 20th centuries […]

  Basically, Watts made up HP to sell his steam engine to mines and likely made up a number to make the new technology seem better.

  Some things never change.
