Methanex to close Taranaki plant after 40 years

Methanex will sell its New Zealand gas entitlements and indefinitely idle its Taranaki plant by Q1 2027 due to declining gas availability. The company employs 300 people and exports 95% of its methanol production. Genesis Energy secured extra gas supplies through 2029, including 11.4 PJ from a third party and 8.6 PJ from Beach Energy, subject to approval.

Background

Methanex Corp (MTRX) is the world's largest methanol producer, with its sole New Zealand plant now slated for indefinite idling after 40 years of operation.

Market effects

Reduces global methanol supply capacity and may tighten margins for other methanol producers.

Alters New Zealand's gas market dynamics, potentially raising gas prices for local consumers.

Limited to methanol and gas sectors; broader market impact is modest.

Counterpoint

The plant idling could free capital for higher‑margin projects, offering a longer‑term upside.
