Hi Community admins and members,

EA's trading conduct report shows storage levels for the years 2021 and 2022 here

I am wondering if data on active storage (Mm3) and lake level(m) for the years 2021 and 2022 are available? I can only view the data for these two indicators made available for lakes upto end 2020 on the EMI platform.

Thanks in advance!

We've almost finished verifying and uploading the 2021 HMD update, which was completed in 2022. FWIW, we've just started the 2022 update so hope to have that ready by about April of 2023.

I don't know the source of the data that the monitoring team are reporting in their trading conduct report but I'd guess it is from the NZX Hydro series (i.e. NIWA data) that we subscribe to.

Thank you, Phil! Is the NZX Hydro data also made available somewhere on the EMI platform?

Best, Ashish

No, because it's a subscription service. That said, New Zealand and South Island aggregates can be seen here.
