List of battery storage power plants

from Wikipedia, the free encyclopedia

The list of battery storage power plants contains individual examples of battery storage power plants from Germany or worldwide. Battery storage power plants are storage power plants that use accumulators and thus electrochemical systems to store energy . The main task of the storage facility is the inexpensive provision of system services . I.e. To cushion peak loads in energy demand, regulate voltage and reactive power, stabilize the frequency of the power grid and avoid additional grid expansion.

More than 700 such systems are in operation worldwide in the context of electrical energy technology , i.e. for power grids . Therefore, only a small selection from the multitude of power plants can be presented here, including particularly powerful plants or plants that are important for German-speaking countries. A list of all systems will be made available online as the United States Department of Energy database .

Australia

As of July 2018, a total of 147 megawatts of electricity from battery storage systems for the power grid are installed and ready for operation.

Hornsdale wind farm

At the end of 2017, after less than 100 days of construction, the world's largest lithium-ion-based battery storage power plant went into operation. The system supplied by Tesla has an output of 100 MW and a capacity of 129 MWh. The system was installed in the Hornsdale wind farm and is operated by Neoen . Just a few weeks after commissioning, it stepped in twice when problems with sudden drops in output arose at the Loy Yang power plant , a lignite power plant in Victoria. The response time of the battery storage power plant was 0.14 or less than 4 seconds, which is significantly lower than that of conventional power plants. In the first six months after commissioning, the costs for system services in South Australia fell by approx. 90%, as the battery storage power plant can intervene much faster and more precisely than conventional fossil fuel power plants. For this period alone, the costs for system services avoided by the storage facility were estimated at more than 30 million dollars. At the same time, the storage facility generated 14% of its investment costs in the first six months.

Other Projects

A follow-up project by the same partners with a battery storage capacity of 20 MWh is to be built in the state of Victoria. The storage facility is to be installed in combination with a wind farm, which should have a nominal output of 204 MW, and, among other things, also supply a 40 hectare greenhouse.

In 2018 a project was started to build 50,000 photovoltaic systems including battery storage for residential and commercial buildings. The partner is the company Tesla, Inc. , as of July 2018, 100 households were equipped with the corresponding technology. In the final expansion, which is expected for 2022, the storage facilities should provide a capacity of 250 megawatts with a storage capacity of 650 MWh. The overall system should work as a virtual power plant and stabilize the South Australian power grid.
