Australian mining and metals corporation BHP has announced a 12-year power purchase agreement with Italian energy giant Enel Green Power that will see the construction of the 76MW Flat Rocks Wind Farm near Kojonup, in Western Australia.

The wind farm will power 100 per cent of BHP’s Nickel West operation from 2024, with 315 gigawatt hours of energy a year to its Kalgoorlie smelter and Kambalda concentrator.

BHP says the deal with Flat Rocks Wind Farm, in addition to previously announced contracts with Merredin Solar Farm and TransAlta’s proposed Northern Goldfields Solar Project, will ensure its Western Australian smelter, nickel refinery and processing operations have a fully renewable power supply, and cut its market-based Scope 2 emissions by nearly 60 per cent.

Nickel West’s operations are destined to supply electric vehicle makers such as Tesla, which demand zero-carbon supply chains.

The $200 million Flat Rocks Wind Farm will feature 18 Vestas V150-4.2MW turbines, the tallest in Western Australia with a tip height of 200 metres.

The project begins construction in July 2022 and will create 120 jobs. Up to 10 locally based roles will continue once it is operational.
