In South Australia, Tesla installed a 100 MW/129 MWh Hornsdale battery in 2017. It was one of the largest batteries in the world and the largest battery in Australia at the time. How the world has altered, my. In the sector of energy storage, Akaysha Energy, a relative newcomer, has announced plans to erect an 850 MW/1680 MWh battery in New South Wales, Australia. That would be the same as a sizable thermal generating station.
The so-called Waratah Super Battery will be the biggest energy storage facility in the world when it enters service in 2025, barring the invention of a rival before then. It will be situated where the Munmorah coal plant once stood; the facility was dismantled in 2017. When finished, it will assist in supplanting the electricity that won’t be obtainable following the closure of Australia’s largest coal plant, Eraring Thermal Generating Station, in 2025.
Akaysha managing director Nick Carter recently told Canary Media that “we believe a successful move to a more sustainable energy future is contingent on the deployment of large-scale battery storage.” In fact, utility scale energy storage technologies play a significant role in reducing the fluctuation of renewable generation and bringing grid dependability and resilience to the networks of the world’s power systems. The Waratah Super Battery is the most important effort to date to close coal-fired reactors and switch them out with renewable energy storage batteries.
Australia’s transmission grid has insufficient capacity to manage brief surges in output in one location and transport it to other population areas, notwithstanding the recent increase in the amount of renewable energy. Renewable energy will be stored by the Waratah battery, although that is not its main purpose. Instead, in the case of outages brought on by lightning strikes or forest fires, it will ensure grid stability by immediately discharging its enormous capacity. According to Carter, having it in place enables the transmission lines to transfer more electricity throughout the day since the battery will fill in the gap if a particular line trips off.
In light of the increasing expansion of renewable energy sources and the fall in synchronous thermal generating, he continued, “this project is a perfect illustration of how existing transmission infrastructure can be used more effectively.” Existing and new renewable generators will be able to provide New South Wales’ residents and companies with energy that is more dependable and stable by releasing the unused network capacity.
A HOME RUN IS HIT BY A NEW KID ON THE BLOCK. It’s unusual for a business to obtain a contract to construct a sizable battery project without having actually built a battery project, but Akaysha has done just that. Despite being new, it is led by seasoned professionals. Managing director Nick Carter previously worked with Macquarie Group’s energy technology group, which was an early backer of grid storage assets. Prior to that, he worked on the Hornsdale Power Reserve project in South Australia and sold utility scale storage for Tesla.
Akaysha team members have experience in autonomous bidding software, market modeling, and optimization, all of which are essential for success in Australia’s competitive power market. In addition to project finance and development.
Akaysha was purchased outright by BlackRock in August on the basis of its team and pipeline of ongoing projects. BlackRock then promised to invest $700 million through Akaysha as its development platform in the Australian grid battery market. Consolidated Power Projects Australia, a seasoned engineering, procurement, and construction company that constructed the Hornsdale battery, will install the Waratah project.
THE TRANSMISSION INFRASTRUCTURE OF BATTERIES The transition from coal to renewable energy frequently entails the usage of natural gas-fired generating units in various parts of the world. However, some regions, like New South Wales, are skipping decades of investment in gas-fired generators and moving straight from coal to a mix of renewables and batteries. Instead of being structured like a traditional power plant contract, the one for the Waratha Super Battery was described as a “virtual transmission solution that will expand the transmission capacity of the existing network.” This will open the door for the new renewable energy that New South Wales plans to use.
According to Canary Media, treating batteries as transmission infrastructure is a relatively new idea. Despite its inadequate transmission and storage infrastructure, New South Wales will be able to handle its spikes in renewable energy by building one of the largest batteries in the world.
