The electricity sold by Tesla comes mainly from the grid or batteries made by Tesla. At the same time, Tesla can also allow Texas residents who have solar panels in their homes to share electricity, and users can make money by selling excess electricity to the grid.
It is reported that Tesla's subsidiary is building an energy storage battery project of more than 100 megawatts in Texas, which can power about 20,000 homes in the hot summer. In February of this year, Texas encountered extreme cold weather, which caused a large-scale power supply interruption in the state. The Texas Public Utilities Commission stated that since then, some electricity suppliers have withdrawn from the local market, and many new suppliers have submitted applications to sell electricity in Texas.
