Grid-forming inverters provide critical grid stability by independently maintaining voltage and frequency
Frequency is the heartbeat of the grid - when it's disrupted blackouts can occur. As more renewables come online, grid-forming inverters are crucial for maintaining frequency and preserving grid resilience
Megapacks are currently operating in grid-forming mode across the globe
'Renewables Don't Cause Blackouts: Grid Reliability Explained'
What's the real cause of poor grid reliability and higher power costs?
Poor regulation, planning, and design.
Solar, wind, and batteries actually increase grid reliability and lower power costs, especially when paired with grid-forming inverters.
So the best approach is an all-of-the-above energy strategy, streamlined permitting, flexible grid policies, and modernized utility operations.
There are engineering challenges with higher levels of renewables, but those will be solved as a matter of course and there are already solutions available off the shelf.
Ultimately, if we want truly limitless power we need to go to outer space, which is what I'll cover in the next video of this series 🤠

2 GWh of Megapacks are co-located with 500MWac of solar in Kern County, California at one of the largest solar-plus-storage projects in the US
The site will be capable of providing clean energy equivalent to the annual usage of roughly 467,000 homes, significantly reducing carbon emissions (over 1 million metric tons of CO₂ per year) and supporting grid stability
Sweet new Supercharger opened on I-5, powered by plenty of sunshine and Megapacks! Operating off-grid ⚡️
168 stalls, 11 MW of solar, 10 @Tesla_Megapack constructed in 8 months in Lost Hills, CA.
84 stalls now open, solely powered by the sun and operating off-grid. Remaining stalls & lounge coming later this year. Safe Fourth of July travels!

The full extent of inverter capabilities won't be leveraged until we can have broad adoption of grid-forming technology!

758 MW of solar supported by 1.2 GWh of Megapack at Arevon’s site in Kern County, California

Now operating - Eland 1, a hybrid solar + Megapack project, owned and operated by Arevon
This is the first project deployed with Tesla's new site-level controls that seamlessly regulate power output to buffer the intermittency of solar and provide a firm resource to the grid. The hybrid configuration allows more solar power to be installed at the site than the interconnection nameplate, while also avoiding costly solar curtailment
ISO Today app still doesn’t get old. Batteries serving 16% of the California grid at 7pm with 7GW+ and a neat looking reverse (generation) duck curve.

Powerwall & @Tesla_Megapack together achieved record storage deployments of 9.4 GWh in Q2

For years we've been hearing how great grid batteries can be, but it was hard to see in action.
Now California's got 10GW online and they're visibly reshaping grid activity. I broke down some of the major trends, as visualized by the folks @grid_status canarymedia.com/articles/bat…

On Wednesday, we hosted our first Megapack Installer Day.
Tesla experts shared insights on installation, commissioning, service, controls, safety and more.
Thanks to our partners who joined!

In 2024, natural gas generation on an average April day in California hit a 7-year low.
This is a significant trend reversal from what we saw from 2021 to 2023 in CAISO.

It looks like having battery storage as the top supply source for a few early evening hours will become common for shoulder months on @California_ISO grid going forward.
Happened again last night from 6:45pm - 8:25pm.

Last Tuesday night, battery storage became the largest source of supply to the California grid for the first time, discharging over 6GW

While most eclipse observers will be staring at the sky, grid operators will be making sure the power stays on in the darkness.
Check out our latest blog on what we'll be watching come Monday

It’s 4pm and not even summer yet, and 56% of California’s power is coming from renewables. Mostly solar, then wind.

Congrats to Plus Power and the Tesla Autobidder team on landing the #1 spot in the @ModoEnergy ERCOT rankings with Gambit in 2023! ⚡️
This Megapack project in Southeast Texas demonstrates how much value energy storage can deliver to the grid with optimized performance

I just came across this collection of 30 energy literacy videos by @StudentEnergy that are an excellent intro to each source of energy, energy units, etc. Bookmark and share with anyone looking for a basic intro to energy!

#Hawaii shut down its last coal plant in 2022. Now, the Kapolei Energy Storage system’s 185 megawatts of instantaneous discharge capacity match what the old coal plant could inject into the grid, though the batteries react far more quickly. bit.ly/41QZuZQ
