The four futures — pick one

stress · eased → acute

capital & demand · stalling → surging

Now · June 2026 ↗ tilting to the top-right (Bowerbird) — El Niño declared (BoM/NOAA), forecast to strengthen (strong, possibly very strong) into spring–summer 2026–27. Near-term tilt toward the acute-stress row; with demand still hot, Bowerbird is the live near-term case.

Current conditions — a starting point, not a probability or a forecast of which future occurs.

A strong Niño3.4 signal doesn’t guarantee strong local impacts (BoM); review when BoM’s ENSO Outlook status changes.

SW WA rainfall is weakly ENSO-driven; the Pilbara is a demand-side water constraint (a Bowerbird signal), not a rainfall drought.

Signposts to watch

Horizon scan — cross-scenario

Australia (WA · Pilbara) — public market signals

Public sources (Water Corporation, AEMO, WA Government, First Nations Clean Energy Network, Mandala / Data Centres Australia). General information only.

New Zealand — public market signals

Published policy & procurement information only — no bid, response or commercial-in-confidence material.

El Niño tends to raise South Island hydro inflows; NZ dry-year / electricity-price risk runs on a separate, La Niña-leaning driver.

Acknowledgement of Country

Ridgeline Advisory acknowledges Aboriginal and Torres Strait Islander peoples as the First Peoples of Australia, and the tangata whenua of Aotearoa New Zealand, as the Traditional Owners and Custodians of the lands and waters this work touches. We pay our respects to Elders past and present, and recognise their continuing connection to — and care for — Country and water, and the central place of that knowledge in the water–energy–infrastructure future.
