Dear Electricity Authority,
Via your organisation's web site https://www.emi.ea.govt.nz/Wholesale/Datasets/Metered_data, half-hourly data on the generation (and consumption) of electricity at various places are provided, in particular for wind farms on the Tararua Range. There have been multiple developments, but this concerns the first, and is associated with the Linton substation as the notional metering position. The supplied data series starts with the year 2000, abruptly, with high values, showing that many turbines are in operation not just the first one or two. Further, the supply from the grid at Linton drops prior to the start of the year 2000, indicating that local generation is partially offsetting the load supplied from Linton. Such as from the early operation of the wind farm.

This request then is for the missing early generation data for the first Tararua wind farm.

Yours faithfully,
Nicky McLean
