Metered data on the FTP site
A collection of metered data files is now available on the Authority’s FTP site – navigate to the ...\Datasets\Wholesale\Metered_data\ - at:
The Authority has traditionally published metered data – or SCADA (supervisory control and data acquisition) data – as part of the centralised dataset (CDS). Such data includes generation by grid injection point, HVDC flows, and active and reactive power by grid exit point. For the months in between the six-monthly publication of the CDS, the Authority has published metered data on a supplementary material page.
As noted in Market Brief on 23 September 2013, the CDS published in October 2013 was the final CDS to be published. Accordingly, the CDS supplementary material page will soon be removed and the FTP site will be the only publication outlet for the metered data.
Please email phil.bishop@ea.govt.nz if you have any questions about the metered data on our FTP site. |
