California-based energy company Pacific Gas and Electric Company (PG&E) has announced the start of construction on a new record-breaking project to store electricity in Tesla megapacks. In the first stage of expansion, the battery system should reach a capacity of 730 megawatt hours, which is already enormous. There’s also an option for Tesla to deliver even more batteries for a total of 1.1 gigawatt hours of capacity – which should make the facility on the California coast the largest in the world for at least a while.
Not only Tesla projects getting bigger
PG&E itself describes the battery park from 256 Tesla megapacks in an announcement this Wednesday as “one of the largest energy storage systems made of lithium-ion batteries owned by a utility company”. Perhaps the wording is so cautious, because new huge battery projects with technology from Tesla or other providers are currently being announced and started.
With a capacity of 193.5 megawatt hours and an output of 150 megawatts after an expansion of 50 percent this spring, the Hornsdale Reserve plant in Australia, which was still implemented with the smaller power packs from Tesla, was previously considered the largest lithium-ion storage in the world. This June, however, the Fluence joint venture with the German company Siemens presented a project to relieve the electricity grid in Australia, the two giant batteries of which deliver 500 megawatts of power and have a capacity of 250 megawatt hours.
Tesla again with world record – for now
With the Moss Landing in California, which is now being built, Tesla should at least be able to use the world’s largest battery storage for the time being. It is expected to be activated at the beginning of 2021 and fully operational in the second half of the year. As usual with storage systems with Tesla batteries, the Autobidder software should also be used here. According to CEO Elon Musk, it was programmed so that small and large Tesla storage units can participate in the electricity market as efficiently and automatically as possible.
