From: Info Electricity Authority <[email address]> To: OIA <[email address]> -----Original Message----- From: Nicky McLean <[email address]> Sent: Friday, 3 June 2022 8:26 pm To: Info Electricity Authority <[email address]> Subject: Official Information request - Please supply missing half-hourly data related to the early operation of the Ohariu wind turbine farm. Dear Electricity Authority, The wind turbine farm at Ohariu ("Mill Creek") generates electricity that is recorded in various ways by data files offered via your web page https://www.emi.ea.govt.nz/Wholesale/Datasets/Metered_data, such as for generation and consumption. Those two data series for Ohariu, as supplied, start with September 2015, but, the wind farm commenced generation in May 2014. So, the first request is for the supply of the missing data on its early operation. Secondly, the generated power has an effect at the Wilton substation (via the local connection to it) in that power is metered as being fed back to the grid at 33KV. The feedback data series starts in July 2014, and I don't believe that there is any other source for such power besides Ohariu, yet the Ohariu data series (as currently supplied) show no generation until September 2015. What supplied this earlier feedback? Is the accountancy wrong? It may well be that there had been no feedback until sufficient wind turbines became operational at Ohariu, presumably some time after May 2014. So, the second request is for the early feedback data from the time it actually began, which may have been in July 2014. Hopefully, with the earlier generation data the accounts can then be in balance rather than in error.
