BHP has signed a renewable power purchasing agreement (PPA) to supply up to 50 per cent of its electricity needs at the Kwinana Refinery from the 132 MW Merredin Solar Farm in Western Australia. The agreement will help BHP reduce emissions from electricity use at the refinery by up to 50 per cent by 2024, based on 2020 financial year levels.
The agreement with Risen Energy is for 10 years from 1 February 2021. This will effectively displace an estimated 364,000 tonnes of carbon dioxide equivalent over the life of the contract. This is the equivalent of removing 11,200 combustion engine cars from WA’s roads every year.
This is the first renewable energy PPA signed by BHP in Western Australia and follows renewable agreements covering BHP’s operations in Queensland in 2020 and in Chile in 2019.
BHP Nickel West, Asset President, Eddy Haegel, said the contract will increase the sustainability of the nickel produced by the operation.
“It will reduce the refinery’s electricity emissions by 50 per cent, diversify our energy supply, and reduce the refinery’s electricity bill,” Mr Haegel said.
“Nickel is a future-facing commodity that is essential to creating the high performing lithium-ion batteries used in battery electric vehicles (BEV). Consequently, the demand for nickel and especially the nickel produced by Nickel West is set to grow dramatically.”
“The sustainable production of nickel is also essential to meet this future demand as the customers purchasing BEVs want to know that the inputs to the manufacturing of these vehicles are also sustainable,” he said.
Mr Haegel noted that Nickel West is already one of the most sustainable nickel producers in the world but has committed to significantly reduce CO2 emissions further.
“This contract, combined with our high-quality nickel deposits, and our integrated value chain further improves our position as one of the lowest carbon nickel miners in the world,” he commented.
Risen Energy Australia, Vice General Manager, John Zhong, said the agreement will bolster current and future Western Australian renewable projects.
“We look forward to welcoming many more clean energy partnerships to power manufacturing, minerals processing and other Western Australian industries,” Mr Zhong added.
The contract will contribute to BHP’s medium-term, science-based target to reduce scope 1 and 2 emissions by 30 per cent by 2030.
