Pumped Hydro

Soon 2020 will only be a worry to future high-school history students. But when they ask us if anything good at all happened in 2020, remember this review and tell them that solar PV shone in the darkness. Despite the mess of it all, 2020 has been another good year for Australian solar. The industry has demonstrated resilience, and significant progress has been made in the fields of energy storage, green hydrogen and others.

Mining company Centennial Coal has received more than $5 million in government funding to investigate the feasibility of turning an old underground coal mine near Newcastle into a pumped hydro storage site which could supply 600 MW of renewable energy to the grid.

One of the few benefits of COVID-19 is the ability to virtually attend conferences that may previously have been a plane ticket too far. Tomorrow’s South Australian Renewable Energy Conference is a window of opportunity …

Australia needs more transmission and network capacity to efficiently use its vast, distributed renewable-energy resources, and to enable transition to a low-cost, zero-carbon electricity supply. In the Australian Opposition’s Budget in Reply it aims to make Australia’s inherent wealth work better for the nation, and puts transmission infrastructure upgrade at the centre of the country’s recovery from Covid-19.

If it was designed with a focus on reliability, security and the lowest cost for consumers, Australia’s main electricity grid would see periods in which nearly 90% of demand is met by renewable generation. A diverse portfolio of distributed energy resources and large-scale solar and wind generation supported mainly by pumped hydro and batteries would ensure the least-cost transition as the nation’s coal plants retire. Adequate investment in transmission infrastructure will be instrumental in making this a reality.

The Australian renewables sector was not immune to a host of challenges that marked the first half of the year, but the pipeline of renewable energy projects in the country reached new heights. While new construction dipped to a four-year low and financial close remained out of reach for a great number of projects, the second half of the year is looking more positive, according to Norwegian consultancy Rystad Energy.

Prime Minister Scott Morrison today announced six of 15 projects to be fast-tracked for jobs creation, among them the Marinus Link interconnector between the Australian mainland and Tasmania, which promises to unlock renewable projects on either side of Bass Strait.

The controversial Snowy 2.0 project has mounted a major hurdle after the New South Wales government this week announced approval for its main works.

In a bid to boost the state’s economy and create jobs amid the Covid-19 crisis, the New South Wales government will accelerate the assessment of 24 projects, including the $4.6 billion Snowy 2.0 pumped hydro storage project.

New analysis highlights the need of, and Tasmania’s potential for, deep storage to back up Australia’s future energy market. Tasmania is determined to become the Battery of the Nation.
