This battery is one of the largest battery energy storage systems in the world.

In Moss Landing, California, PG&E has been working with Tesla to install its Megapack utility-scale

Once complete, it will help store energy for redistribution during off-hours when solar output

California needs generation for our, September, August is our key areas of when we need

storage to be able to capture it during the day and then release it in the afternoon, evenings.

Even as nations around the world set goals to transition to renewables, demand for these

large-scale storage systems is on the rise.

The market size of grid-scale battery storage is expected to become a $15 billion market by

Now we're seeing in many parts of the world, in California, in Germany, now in China, mandates to

have a certain amount of storage available per unit of renewable energy.

If you look at resource forecasts or resource plans, the expectation is there will be tens of

thousands of megawatts of new energy storage in just California.

Welcome everyone to, basically the announcement of Tesla Energy.

Tesla got into the energy business in 2015 and it's betting it will become increasingly important

for the company. In 2020, it surpassed three-gigawatt hours of energy storage deployments

in a single year, largely due to the popularity of Megapack, like the one being built in Moss

I think long term Tesla Energy will be roughly the same size as Tesla Automotive.

I mean, the energy business collectively is bigger than the automotive business.

They have really deep tactical knowledge of batteries, not just the cells themselves, but how

to operate them, how to build a battery management system, how to package them well, make

sure they're in the right kind of thermal window.

The systems have smart technology built into them.

The technology and the way the batteries are actually configured is one thing.

But equally significant at the moment is how you control them.

Tesla has a system called Autobidder that actually chooses what the battery does and when it

The amount of data we get from each mega pack is phenomenal.

The Tesla product has got a lot of technology built into it.

It's really an answer to one of the big challenges we've got.

We all know that we're transitioning our electricity systems to renewable.

Energy storage has been around for a hugely long time, but for a very long time, the only real

viable technology was actually the lead acid batteries in our cars.

The one, of course, that was ramping up during those same decades were lithium ion batteries.

The first lithium ion batteries were used in consumer electronics in the late 1990s.

We can thank Sony's Handycam for pioneering this innovation for us.

Lithium ion batteries are now everywhere, from electric vehicles to our phones.

Though there are many other types of batteries in the works, lithium ion is still the most cost

In the past, prohibitively high costs have meant that lithium ion batteries couldn't be used at

In the past decade alone, according to estimates from BloombergNEF , costs fell about 90

With the world transitioning to electric vehicles, demand for electricity could be greater than ever

People are moving towards electric vehicles.

Roughly you need twice as much electricity if all transport goes Electric.

And you need three times as much electricity if all heating goes electric.

This is a prosperous future, both for Tesla and for the utilities.

And with the recent failure of the power grid in Texas and brownouts in places like California,

energy storage is becoming necessary to keep power up and running.

There is a new impetus behind building out a stronger, more resilient grid.

We've seen again and again our grid can't handle climate change, can't handle these climate

disasters that are becoming increasingly frequent.

Tesla built one of its storage systems on the Hawaiian island of Kauai in 2017.

In addition to supporting the SolarCity solar farm, it's added more reliability for the utility.

We had our best reliability ever as a co-op last year.

Part of running an electric utility grid is you have to always match every second of the day

Batteries are amazing at that because batteries are instantaneous.

If you look at some of the events for the batteries responded to, it's gone effectively from

zero to full output in a bit over 100 milliseconds.

And it's just, there's no other technology that can do that.

In the U.S. and around the world, more aggressive energy storage policies are being put in place.

China has mandated energy storage as part of its effort to reach 16.5 percent solar and wind in its

In Biden's recently unveiled more than two trillion infrastructure package.

There's more than $600 billion earmarked for climate related policies, and that includes $100

President Biden has set 2035 as the 100 percent clean electricity date.

Just meeting that one's going to be not only a big challenge, but also a market opportunity for

Tesla is one of several companies working on energy storage.

Tesla gets, and they deserve to get, a lot of attention for their effort to build the

There's a whole range of startup companies in the storage space.

The majority of grid scale, energy storage, lithium ion battery, energy storage is being built

out by utility companies such as NextEra Energy down in Florida, Duke

Energy. These are a few of the names that are integrating battery storage into their models.

AES Corporation has been working on a number of projects, most notably with Kauai Island Utility

Cooperative. In 2019, it completed a 28 megawatt solar farm with a battery capable of storing 100

megawatt hours. And it just brought a microgrid online at the island's Pacific Missile Range

facility. With the success of these projects, the utility cooperative is working with AES on a new

project to combine solar and hydro for even greater storage capacity.

It's going to have two hours of battery that can handle the solar output.

Well, what's really wild about this one is it's going to also have pump storage hydro power

brought in. Pump storage has been around for decades.

So it's a proven technology, but linking it into an intermittent resource such as solar is a new

Next to the PG&E and Tesla storage project in Moss Landing, Vistra is also building one of the

largest battery systems at its natural gas power plant.

Phase one of the project was completed in December of 2020, bringing 300 megawatts of
