Please supply January's data files for half-hourly generation and consumption. February is ending!

Nicky McLean made this Official Information request to Electricity Authority

The request was successful.

From: Nicky McLean

Dear Electricity Authority,
Via your organisation's web site https://www.emi.ea.govt.nz/Wholesale/Dat... some seven sub-directories give links to files containing data on the half-hourly generation and consumption of electricity at many places across the country, all grouped into monthly files. These data files are supplied in the following month, generally around the second week, thus the data files for December 2021 appeared in the middle of January 2022.

The data files for January 2022 have yet to appear, and now it is the end of February. Can they please be supplied?

Yours faithfully,
Nicky McLean

Dear Mr McLean,

As indicated in the Electricity Authority's response to your request under the Official Information Act 1982 of 19 December 2021, the Authority intends to publish the final energy price and final reserve price files exactly as received from the pricing manager for all months from July 2009 to January 2022 by 28 February 2022.

I can confirm that the requested information will be available on the EMI website by close of business today (28 February 2022).

Kind regards,

Tessa Ballinger

Dear Ms. Ballinger,
Thank you for your rapid reply, however this request does not concern the Final and Reserve price data files that you mention. It concerns quite different data on electricity generation and consumption.. II have just checked for today, and now found them to be offered via links on your website..
Success!

Yours sincerely,
Nicky McLean

Dear Ms. Ballinger,
This is to confirm that the January data files for generation and consumption did indeed contain the usual data (and they for January), so all is well on that issue.
However, I noticed in https://www.emi.ea.govt.nz/Wholesale/Dat... the presence of a malformed file name, 20201_HVDC_flows.csv. The data file was not quite empty, containing only the standard header line and thus being far smaller than the other data files. Having a systematic naming scheme for files and listing them in order makes it easier to notice errors and thus prevent their publication - just glancing at what comes first and what last is easy - but, one does have to make the effort to look for this to work.

Yours sincerely,

Nicky McLean
