Huge 1,100MW offshore wind farm proposed in W.A. by oil explorer – RenewEconomy

Oil and gas explorer Pilot Energy is to commence a feasibility study into a massive 1,100MW offshore wind project, to be located on the Western Australian coast, and form part of a major wind and solar energy hub as the company looks to diversify its business outside of the fossil fuel sector.

The ASX-listed company announced on Friday that it would commence an early assessment of the proposed Mid West Wind and Solar Project, which could see some of the world’s largest offshore wind turbines deployed in waters previously earmarked for oil and gas exploration.

The company has a majority stake in an oil and gas exploration permit that covers an area of more than 8,600 square kilometres of Western Australian coastal waters, and the company believes the region could also serve as an ideal site for an offshore wind farm.

The project could also draw upon a 160-hectare onshore site, as part of Pilot Energy’s existing operations at the site for the installation of a solar farm. Only one other large offshore wind project has been proposed for Australia, the 2,000MW Star of the South proposal in Victoria’s Gippsland, although it is still waiting for federal environmental approvals.

Pilot Energy chairman Brad Lingo told RenewEconomy that the Mid West project would be able to take advantage of high quality wind and solar resources, as well as drawing upon the work the company had previously undertaken to gain rights to oil and gas exploration at the site.

“This is exactly the type of development that demonstrates the ability to substantially redefine how the Australian offshore oil and gas industry can, in parallel with existing operations, participate in a low carbon future through offshore renewable energy projects delivering substantial low cost energy to Western Australia,” Lingo said.

“The substantial nature of the offshore opportunity in Western Australian also presents the option to supply renewable hydrogen for domestic residential and industrial consumption as well as the potential to supply international markets.”

Lingo added that the proposed project would be located close to the existing Three Springs substation, and would face no limitations on generation or network capacity, although RenewEconomy suspect that some upgrades might be needed for a project of that size.

The company said that the planned project would help to diversify the oil and gas explorer’s business in recognition of the growing green opportunities in Western Australia.

The company pointed to an assessment undertaken by Geoscience Australia, which identified the mid-West region of Western Australia has one of the highest potential locations for investment in hydrogen production and export facilities, due to high quality wind and solar resources and access to export markets.

The company says that the wind and solar project could supply power to the Western Australian electricity system, and could potentially be used as a source of renewable electricity for use in the production of green hydrogen. The feasibility study will include an assessment of the viability of supplying hydrogen for domestic use, or for export.

The mid-west region of Western Australia has already attracted proposals for large scale wind and solar hydrogen projects from the likes of Siemens and oil giant BP. Further to the north, iron ore miners are looking at wind and solar and batteries to power their operations, and CWP and others are looking at a massive 15GW renewable energy hub.

“This is only the beginning of the process to establish the overall feasibility of the project but it is a very good first step and Pilot’s existing footprint and management experience provides a unique opportunity to participate in the energy transition as a dedicated energy solutions provider,” Lingo added.

“Pilot strongly believes that focussing on the energy transition provides the opportunity to deliver strong growth and significant shareholder value.”

The Swedish HYBRIT project recently completed construction of a pilot facility that will use green hydrogen to produce fossil-free steel, with an aim of brining green steel to market by 2026. The Grattan Institute has argued that the production of green steel in Australia could be the most effective way to utilise green hydrogen, avoiding the need for costly export of hydrogen and revitalising an Australian manufacturing sector.

Pilot Energy’s feasibility study will consider the deployment of up to 78 offshore wind turbines and could utilise some of the world’s largest wind turbines currently available, with a generation capacity of 14MW.

Lingo said that the deployment of offshore wind turbines enabled the use of larger turbines, as well as providing access to more consistent wind resources, with the project having the potential to achieve capacity factors in excess of 60 per cent, around double what can be achieved by onshore wind farms.

The project could see up to 1,100MW of offshore wind generation capacity build off the Western Australian coast across four stages. It would also involve the deployment some of the world’s largest wind turbines, significantly surpassing the size of any turbines used at onshore wind farms in Australia.

Earlier this year, wind turbine manufacturer Siemens Gamesa announced at it had launched a 14MW wind turbine model, which boasts a 222-metre rotor diameter with 108 metre long blades.

The company said that it expects to spend around $1.2 million on the completion of the feasibility study, and will assess the next steps for the project when the outcomes are known, including identifying suitable co-investors in the development.
