On several sites that allow viewing of UK power production figures Pumped Hydro figures is provided when discharging (providing power to the grid) but not when charging (taking power from the grid) as far as I can tell. Is this because the sites choose to only display discharge or are the figures for charing not available? With Interconnectors the power is shown for both supply and demand.
With more and more grid batteries appearing are the figures for these available? If so I assume these are part of the "other" generation figures - which again only show discharging of the battery and not charging.
