Meridian nominates Price Separation Periods under
electricity agreement with NZAS

5 April 2022


Meridian Energy Limited (Meridian) has given notice to New Zealand Aluminium Smelters Limited
(NZAS) that it has nominated a number of trading periods as Meridian Price Separation Periods in
accordance with the terms of the electricity agreement between Meridian and NZAS (the Agreement).
The price separation observed between the Tiwai and Benmore spot prices is the result of
exceptionally dry conditions across Southland with the Waiau catchment experiencing its lowest
inflows on record for the January to March period and these conditions limiting generation at
Manapōuri. Lakes Manapōuri and Te Anau are now both in their low ranges under the Operating
Guidelines.

Under the Agreement, Meridian may nominate a trading period as a Meridian Price Separation Period
when the Benmore spot price is less than 85% of the Tiwai spot price in that period and the additional
criteria in the definition of “Meridian Price Separation Period” in the Agreement have been met.
The relevant Meridian Price Separation Periods occurred on 2 April 2022.

This is the first time under the Agreement that Meridian has nominated trading periods as Meridian
Price Separation Periods. If current conditions persist, further Meridian Price Separation Periods may
be nominated.

The Agreement provides that for trading periods nominated as Meridian Price Separation Periods, the
contract quantity offered by Meridian reduces from 540 MW - 572 MW, to the reconciled quantity of
generation actually produced by the Manapōuri hydro power station and White Hill wind farm in the
relevant trading period(s).
