The Tesla Powerpack is a rechargeable lithium-ion battery stationary energy storage item, intended for use by businesses or on smaller projects from power utilities.
The Powerpack stores electricity for time of use load shifting, backup power, demand response, microgrids, renewable energy integration, frequency regulation, and voltage control.
Starting in 2012, Tesla installed prototype battery packs (to later be called the Powerpack) at the locations of a few industrial customers.
[3] In November 2013, Tesla announced that it would build Giga Nevada, a factory to produce lithium-ion batteries, like those used in the Powerpack.
[4][5] The success of the early Powerpack installations led Tesla to announce in April 2015 that it would apply its technology to a home energy storage system, the Powerwall.
For example, a 25 MW / 52 MWh deployment of Powerpacks is in use at the Lake Bonney Wind Farm in South Australia.
[clarification needed] The Powerpack was projected to comprise the majority of stationary storage production at Gigafactory 1 while Powerwall would play a smaller part, giving Tesla a profit margin of 20 percent.
[27][28][29] Sonnen and AutoGrid collaborated on combining house batteries into a large-scale utility-level grid storage system.
