AGL long-duration battery planned for Adelaide marks another leap for renewables

The announcement in Adelaide for a massive long-duration battery was a landmark in the advancement of technologies to promote wind and solar energy in comparison with the fossil fuels.

AGL, which operates a range of coal-fired plants and the largest greenhouse gas emissary in Australia, confirmed today that the Torrens Island gas station will install a large-scale batteries, which will be shut until 2022.

The study said the battery was installed in phases and could be operated up to 250 MW — more than an established Hornsdale battery in southern Australia but less than a 300 MW plant was expected to run at a location near Geelong.

The production of AGL ranges markedly in length for up to four hours from current and other planned Australian batteries.

Established Australian batteries are used to boost grid protection anytime anything goes wrong, such as cutting a large transmission line or "dripping" a power plant.

They will fill the void efficiently enough that the grid does not fail.

The AGL battery will be the first in the world to store electricity generated by sunlight or by wind, and discharge the battery into the grid at peak power usage.

In comparison to other recent coal, battery and pumped hydroprojects, funded by the federal government and other governments, it is worth remembering that the company's decision has been taken without government funding or interference.

Brett Redman, CEO of AGL, said the firm was "going ahead with the energy transition business."

"This battery marks another step in the state's energy transfer and allows a rapid reaction when our customers and communities need it to change renewable generations," he said.

He said the battery on Torrens Island was part of an energy storage planning of 850 MW by 2023-24.

Technologies of batteries have gone off sooner than anticipated.

An Australian electricity market operator's 2016 prediction found that by 2020, the nation will only install 4MW of big batteries and that only by 2036.

The nation has either 287MW in service or is dedicated to building, a study published earlier in this month.

The news of the 300 MW battery near Geelong, which is considered one of the largest in the world, does not involve that.

The Torren Island battery was a vital achievement for Simon Holmes à Court, a senior advisor at the Environment and Energy College of Melbourne University, who would have chosen for a modern gas power station.

"This is Australia's first gas generator battery and is totally unsubsidized," he added.

"When demand reaches its peak, Solar will move from midday to night."

The government of South Australia said it will help the battery with a programme waiver.

Energy Minister Dan van Holst Pellekaan announced that it will help restore the grid to power" and achieve his aspirational goal of net 100% renewables.

In the last year, South Australia generated 57 percent of renewable energy.

The government of Morrison claim that the stability and protection of the national grid relies upon modern gas-fired power plants as intermittent wind and solar power replacements for outdated coal power plants.

It aims to undertake up to five new gas plants and six hydropumped projects at an accelerated start-up and says Snowy Hydro of the government will develop an additional gas generator to help offset the outgoing AGL coal-fired plant in New South Wales if the private sector fails to pursue an equal investment in April. By April this project will proceed.

The latter plan was revealed as part of its "gas-driven" rebound from Covid-19's economic shock.

Earlier in this year the market regulator noticed that additional gas fired electricity was a choice but not indispensable for the clean energy production network and if it wanted to contend with pumped hydrogen, batteries and other options, the gas prices would have to remain below planned amounts.

Almost half the coal emissions of gas are frequently represented when burnt, but new reports have shown that its effect on the atmosphere is underestimated.
