The dataset contains half-hourly metered apparent real and reactive power data for individual zone substations in the Jemena supply area from 2007 onwards. The data is intended to be ongoing and is updated prior to 31 December annually.

Note that reactive power measurements may include zone substation capacitor banks (this is noted in the dataset itself with 'Transformer MVAR').

Note that the Jemena zone substation dataset has since been translated into a form that is consistent with all other zone substation data hosted on EUDM. The translated dataset is available through the Related Resources listing on this page.
