Summary
DescriptionGeothermal.Electricity.NZ.Poihipi.png
English: Generation at the Poihipi geothermal power station, half-hourly figures grouped daily and plotted as magenta (max-upper quartile), green (min-lower quartile), red (median), pale blue (daily average) stepwise dark blue (weekly average), black step (annual averages), black line (overall average). The spike is due to a single value, likely an error but unacknowledged as such by the generation company.

More data (via Gnash, available through https://www.dropbox.com/scl/fo/ybht00jahx8mzto4jrzkk/h?rlkey=jyosqn7mp34vqyf40s4triub6&dl=0), and plotted via Octave and a screengrab because print -dpng (or svg) damages both the on-screen image and the resulting .png file.

Replot with additional years of data, done via Octave and screengrab. (Still fails for direct .svg or .png production) Later years show a fall in production from the plateau.
