Australia said on Wednesday (Aug 21) it had given the go-ahead for a A$20 billion (US$13.5 billion) solar project that plans to ship energy from a giant solar farm in the country's north to Singapore through a 4,300km undersea cable.

Environment Minister Tanya Plibersek said SunCable's flagship Australia-Asia power link project would help meet the growing demand for renewable energy at home and abroad.Plibersek said the vast solar farm would generate enough energy to power three million homes and would include panels, batteries and eventually, a cable linking Australia with Singapore.

"It will be the largest solar precinct in the world and heralds Australia as the world leader in green energy," she said.

A final investment decision is expected in 2027 with electricity supply to begin in the early 2030s, according to SunCable.

The approval comes with strict conditions to protect nature and the project must avoid the habitat of greater bilby, which are small rabbit-like marsupials with long floppy ears, Plibersek said.

Over two stages of development, the project aims to deliver up to 6 gigawatts of green electricity to large-scale industrial customers in Darwin, the capital city of Australia's Northern Territory, and in Singapore.The approval comes as the centre-left government ramps up renewable energy projects even as the opposition coalition proposes building nuclear plants to replace coal-fired power by 2050, in a country where nuclear power is currently banned.

SunCable, owned by billionaire Mike Cannon-Brookes, said the approval was "a vote of confidence" in the project.

Cannon-Brookes, the co-founder of tech firm Atlassian turned environmental activist, last year said the project was viable and that outside investors would be drawn to the project.

"SunCable will now focus its efforts on the next stage of planning to advance the project towards a final investment decision targeted by 2027," SunCable Australia Managing Director Cameron Garnsworthy said in a statement, which did not provide details of its financing plans.

SunCable said it was in talks with Singapore's energy regulator on the conditional approval for the project's cable inter-connector component and with the Indonesian government on building the cable in its waters.

The project received clearance from the Northern Territory government and the territory's environment watchdog last month.
