...experience gained from the operation of a microhydro plant, probably of interest mostly to other Powerspout owners. At the start, in 2014, it was new and there was much to write about but as time has passed there is less. So new posts will only be written if something interesting comes along, - look below to see if there is a new post.

6 years of output data
With September coming to an end, another 12 months of data is complete to illustrate how my Powerspout has performed. Happily, it has been a good year with total energy generated as good as the best of the previous years. Below are three plots showing:
output on a day to day basis between October of one year and September of the following year, covering the past 6 years
cumulative output through the same 12 month period for the past 6 years
the total number of days in each 12 month period that a given output was achieved, also for the past 6 years
In each plot, the 2018-19 year is represented by a black line and previous years by coloured lines. 1
