Tesla Megapack battery could power San Francisco for 6 hours

Tesla Energy Goes Mega

Tesla's Megapack is a battery built for the electrical grid

According to Tesla, Megapack reduces the complexity of large-scale battery storage and provides an easy installation and connection process as each Megapack comes from the factory pre-assembled and pre-tested in one enclosure from Tesla's Gigafactory-including battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls.

Tesla, the forerunner in creating innovative devices, has come up with a new product called Megapack, a utility-scale energy storage product. In 2015, Tesla released a product called Powerpack, which is essentially an industrial version of Powerwall meant to be "infinitely scalable".

As the name implies, the Megapack is a mega-evolution of its Powerpack, the largest lithium-ion batteries in the world that it launched nearly two years ago. Just as important, Tesla says that it can deploy an emissions-free 250 MW, 1 GWh power plant in less than three months.

Tesla has taken on increasingly massive energy storage projects over the last few years. That 100-MW/129-MWh system was hooked to Neoen's Hornsdale wind farm. Since then, the facility saved almost $40 million in its first year alone and helped to stabilize and balance the region's unreliable grid.

Each Megapack connects to Powerhub renewable energy monitoring software, and can also be integrated with Tesla's machine-learning platform, Autobidder, which allows for automated trading in electricity markets.

The first deployment of the Tesla Megapack will be in California, where the Pacific Gas and Electric Company (PG&E) is working on the Moss Landing project. Megapack is meant for bigger installations, with Tesla claiming each system has a 60 percent increase in energy density.

"Megapack is designed for utilities and large-scale commercial customers", Tesla said. It says the battery will be a sustainable alternative to expensive, polluting gas peaker plants. They cost millions of dollars per day to operate and are some of the least efficient and dirtiest plants on the grid.

The Megapack array will store excess wind and solar energy to support the national grid at times of peak demand.
