Australia Leading In Renewable Energy-Rooftop Solar Alone Will Meet 100% Energy Demand In South Australia By October


Dear Friends, Visitors/Viewers/Readers,

This is a repost from one of our sister publications, Windermere Sun, below:

On Monday, September 20, 2021, the share of renewable energy (solar, wind, and hydro) on Australia’s main electricity grid shot above 60% (at 60.1%) for the first time at 12:10 pm, exactly one day and 15 minutes after its previous peak and record of 59.8% on Sunday, September 19, 2021, according to Dylan McConnell of the Climate Energy College in Melbourne, Australia, using data from OpenNEM. This new peak highlights the increased pace of transition into the clean or renewable energy and the shrinking output of coal as more solar and wind are rolled out across Australia. According to another data watcher, Geoff Eldridge from NEWLog, Sunday, September 19, 2021,  did not just break the record for the share of renewable energy, but also the record for instantaneous wind and solar at 57%. The Australian Energy Market Operator also noticed: NSW record maximum rooftop solar PV (2,694.4 MW) and corresponding lowest minimums for network demand (4,867.4 MW) and Operation Demand (5,065.0 MW) and tweeted on Friday, September 24, 2021, “Spring is the season for records to bloom! Forecast mild temperatures and sunny weather in NSW and QLD on Sunday may see rooftop solar drive down energy demand from the grid to a new record low!” With such occurrence, NSW, the Australian state grid with the highest dependency on coal generation, would find it easier to align with the state government’s push to replace the aging coal fleet of more than 10GW with wind, solar, and storage under its renewable infrastructure plan. According to Eldridge of NEMLog, coal output on the main grid was at a record minimum of 9,161.6 MW at noon on Sunday, September 19, 2021 (or, at leas the lowest since Nov. 1, 2020), and was down 153.57 MW on the previous minimum on Sunday, Aug. 22, 2021. It was also a record low share of coal generation (38.97%) on the main grid and for combined coal and gas (40.05%). The share of solar and wind could have been significantly higher were it not for the level of curtailment, either economic (switching off to avoid negative prices) or network (being forced to switch off due to grid issues or capacity constraints). On Sunday, September 19, 2021, the level of curtailment was more than 3.5 GW when that short-lived record was set. As the rollout of solar, wind, and storage (both battery and pumped hydro) continues to enter the grid, more records will change. AEMO forecasts that the rooftop solar, alone, will be able to reach 100% of demand in the state of South Australia some time this Spring (of Australia), around October, a FIRST for any gigawatt scale grid in the world! AEMO is also predicting that rooftop solar could meet up to 75% of demand on the entire main grid within next five years and is preparing the national grid to accommodate times of up to 100% solar and wind by 2025.

Australia is preparing to build the world’s most powerful solar power plant. Engineers and builders will have to solve complex problems to cover an area equal to 17 thousand football fields that accommodate photovoltaic panels with a total capacity of 10 Gigawatts. The second challenge will be to transfer this energy to Singapore, the main consumer of electricity.  There is also talk of exporting energy to Indonesia and various parts of Asia. But how exactly will the power plant be able to power a country more than three thousand kilometers away?

  To begin with, it is worth understanding why energy problems have arisen in one of the most developed countries in the world. Australia faces regular power outages, and, unfortunately, South Australia suffers the most. There may be a lot of reasons: for instance, in September 2016, due to a storm, almost the entire state was left without electricity. One reason for the outages is that there are not enough storage facilities on the territory to supply more electricity during peak loads. The local authorities could not ensure the commensurate development of their own energy or storage capacities capable of providing electricity supplies during calm or cloudy weather. And it is quite difficult to restore the network because of the climatic conditions and long distances – Australia is not a tiny country. At the same time, electricity prices in the country are considered one of the highest in the world, in the video published on Jan. 13, 2021, “HOW ELON MUSK MANAGED TO SOLVE THE ENERGY CRISIS IN AUSTRALIA“, below:
