Tesla announced called a new huge battery today Megapack which can replace so-called "peaker" power stations, which supply energy when a local electricity grid becomes overloaded. Tesla says Pacific Gas and Electric (PG&E) will deploy a Megapack in Moss Landing on Monterrey Bay in California, that is one of the four locations where the California utility plans to install more cost-effective energy storage solutions.
Each Megapack can store up to 3 megawatt hours (MWh) of energy at the same time and it is possible to string enough Megapacks together to make a battery with more than 1 GWh of energy storage, says Tesla. The company says this would be enough energy to "power every home in San Francisco for six hours." and controls. Tesla says that the Megapack takes up 40 percent less space, requires a tenth of the parts to build and can be assembled 10 times as fast as alternative energy storage solutions.
Tesla has taken on increasingly large-scale energy storage projects in recent years. The company has been selling its Powerwall batteries for home use for around four years, capturing and storing energy from solar panels. In 2015, Tesla released a product called Powerpack, which is essentially an industrial version of Powerwall, intended to be "infinitely scalable". Tesla recently built the largest lithium-ion battery in the world in Australia with Powerpacks. It has a capacity of 129 MWh and can deliver 100 MW of power.
These more industry-oriented products have helped keep the energy side of Tesla & # 39; s company afloat at a time when solar panel activities are struggling. The company installed less traditional solar panels in the second quarter of 2019 than in any other quarter since it purchased SolarCity in 2016. (It would also be the lowest installation rate for SolarCity since 2013.) Tesla closed ten solar installation centers in early 2018 and also supported a deal to sell solar panels to Home Depot, and has handed the industry leader that SolarCity once had.
The company has worked for years on finishing the & # 39; sunroof & # 39 ;, a version of the next generation of solar panels in the form of roof tiles. CEO Elon Musk unveiled the sunroof in 2016 when Tesla was taking over SolarCity, but the complexity of the product led to delays in the rollout. (Tesla has installed sunroofs on a few houses and said Monday in a financial request that it plans to "expand" installations to "eight states in the United States in the second quarter of 2019," although Musk said it company is still finishing the third version of the design.)
Tesla deployed 415 MWh of Powerwalls and Powerpacks in the second quarter of 2019, a record for the company. During 2018 and early 2019, the company had to reduce the number of Powerwall and Powerpack products because it needed the batteries to support the dramatic increase in Model 3 production.
