In February, Tesla and the South Australian government announced a plan to create the world’s largest virtual power plant – 50,000 5-kilowatt rooftop solar home systems, each paired with a 13.5-kilowatt-hour battery, for one total system output of 250 megawatts and 625 megawatt hours of storage. So far, the installation has been carried out in 100 homes and the results are successful.
In a statement, the government praised the first virtual power plant (VPP) systems for “providing cheaper electricity to South Australians who need it most“, And to increase the reliability of the state power grid. Preliminary test results show that Tesla Powerwalls systems installed in homes can offer excellent performance when it comes to providing a fast and efficient response to changes in the corporate network.
A report prepared by Tesla says: “This response demonstrates SA VPP’s ability to autonomously and instantly provide services that help maintain network stability.Tesla’s conclusion was supported by the government, which says Phase 1 trials demonstrate distributed Powerwall batteries can increase power supply during peak periods, increasing reliability and lowering electricity prices. in South Australia “when combined with solar and wind power“.
Michelle Lensink, Minister of South Australia, said Renew the economy that the Tesla VPP project was “incredibly beneficial“In the sense that it offers an essential reduction in the electricity bill for the tenants of Housing SA. “This project offers Southern Australians invaluable help in paying large electricity bills while tackling the daily cost of living.The systems are installed without a down payment and will be paid over time as part of the monthly charges for these utilities. Even with these payments, I was told. the average monthly bills of the first 100 participants are around 30% lower than they previously paid for electricity.
In addition to completing the rest of the Tesla Virtual Power Plant system, the Liberal government that came to power in March is expected to announce $ 100 million in grants to install battery-powered storage systems in an additional 40,000 homes in South Australia. . Other companies, notably Sonnen, will be involved in the battery storage aspects of these new facilities.
A number of VPP and micro-grid trials are underway across Australia, but the planned 250 MW facility is by far the largest virtual power plant proposal in the country or anywhere else in the world. Most organizations involved in Australia’s electricity industry, including CSIRO, grid owners and the Australian energy market operator, agree that half of the demand will be met by distributed generation. – including solar energy. on rooftops coupled with residential storage batteries – for decades to come.
