In the year 2019 Tesla announced the Megapack battery, which is similar to the shipping container, specifically designed to shut down gas and coal-fired "peaker" power plants.
Peaker plants remain inactive for the majority of the time However, they come on to generate additional energy when the demand for electricity is high as the grid is unable to keep up.
Tesla offered Megapack battery packs as a environmentally friendly alternative to peaker plants.
Because they are able to store renewable energy even when the demand for electricity is low and then pump energy back into the grid when demand increases.
In the past one year Tesla increased the rate of development of major battery initiatives. The Megapack is beginning to live up to its promise of killing plants at peak.
Tesla constructed its largest battery ever in April. It will aid in helping California energy utilities Pacific Gas and Electric replace natural gas power plants.
Tesla will construct its third and second largest battery projects to close the last coal-fired plant in Hawaii.
Help to in the replacement of one of the most carbon-intensive coal plants located in New Mexico.
Tesla is speeding up the construction of battery systems for utility scale.
Megapacks are batteries that can be used for utility which means that power companies could use them to backup store power for thousands or hundreds of customers.
Every Megapack battery has the capacity to hold three megawatt-hours (MWh) of energy enough to power around 100 US homes for a full day.
Tesla's largest battery installation comprises 256 Megapack batteries with an aggregate storage capacity of 730 MWh.
This is enough to power around 255,000 US homes for a full day or close to 600,000 homes in an hour.
