With the development of productioncalled "green energy" (solar and wind), the market begins to need new solutions to store this energy in large volumes. About two years ago, we wrote about how Tesla actually built the world's largest lithium-ion battery with a capacity of 100 megawatts in Australia based on the Tesla Powerpack energy storage in a 100-day dispute. But the company decided not to stop there. Today, Tesla is a new system for "large-scale" energy storage. The project is called Megapack.
Your own way in the development of storage systemsEnergy Tesla began with the creation and production of household Powerwall batteries, which allow the storage of electricity from solar cells installed on rooftops. For business-oriented solutions, the Powerpack system was later introduced. Judging by the latest announcement, the company decided to seriously focus on the industrial scale of energy storage systems.
What is Megapack?
Tesla reports that Megapack issystem of modular batteries, the size of which does not exceed the size of the shipping container. Batteries can be connected directly to solar panels. The power of each Megapack battery is 3 MWh. This is about 14 times more than the Powerpack storage capacity, which is capable of storing around 210 KW / h of energy.

The company indicates that the battery MegapackThese are completely ready-made solutions, equipped with all the additional equipment necessary not only for storage, but also for the redistribution of electrical energy.
Why do we need such systems?
According to the company, the main advantageMegapack batteries is that they can be combined into large energy storages based on environmentally friendly sources with a capacity of 250 MWh or 1 GWh. At the same time, Tesla notes that the installation and connection of such a system takes less than three months, which is four times faster than building and launching a power station of similar power on fossil fuels (for example, coal). In addition, Tesla notes that the Megapack battery-based station will take up 40 percent less space than similar capacity offers.
All elements within the Megapack common storage system interact with Powerhub's central management system, which helps monitor and control all objects.
According to the company, the reserve energy of 1 GWh will be enough to provide all the houses in San Francisco with electricity for six hours.
Megapack is not a complete replacement for the usualpower plants, but the system can be used as a temporary backup source of energy during peak loads and power outages. Usually in such cases special stations are used. They are very expensive to build, and every day the work of such a station can cost millions of dollars, the Tesla website indicates.
