Australian Household Photovoltaic + Energy Storage Mode Become A Hot Spot

Jul 08, 2019

Australia has vigorously built power grid-level energy storage power stations, which has improved the safety and adaptability of the power grid. For example, when the LoyYang coal-fired power plant in South Australia failed off-grid, the Hornsdale Energy Savings Center responded quickly and started within 140 milliseconds, adding 100 MW to the nation's power backbone. As a grid-level battery energy storage center, Hornsdale reduced its grid-assisted service costs by 50 million Australian dollars (about 240 million yuan) in 2018. In addition to the Hornsdale Energy Savings Center, Australia has built energy storage power stations in Dalrymple, South Australia, Ballarat and Gannawarra, Victoria, and Alice Springs in the Northern Territory, with a total scale of 190 MW.

The Australian government has also vigorously promoted the installation of energy storage batteries in residential photovoltaic systems. The South Australian government was the first to introduce the HomeBatteryScheme in 2018. The plan will cost A$180 million (about 850 million yuan) to help residential users purchase batteries for their home PV systems or match battery capacity in the form of low-interest loans or rebates through Clean Energy Finance Corporation. Photovoltaic components. In addition, in November 2018, the Federal Labor Party declared that if the party wins the election, the Federal Labor Party will propose the "Household Battery Program" to support the installation of 100,000 household energy storage batteries. All of these government support programs will enable 70,000 residential homes in Australia to use battery storage in 2019. This also means that in 2019, the Australian household energy storage battery market will account for 30% of the global market.

The continuous implementation of energy storage projects has improved the reliability of the power grid. Despite the individual load shedding during extreme summer weather, the number of minutes of power outages per unit customer in 2018 was 134 minutes, only half of 2017 (274 minutes) and the lowest since 2012 (138 minutes). In 2018, the reliability of Australia's national energy system reached a historically high level.
