In Texas, this seems dumb. We have .more than enough energy. So you discharge your truck for ztesla to make $$ then have to recharge it to drive and pay more $$$.

I’m curious what kind of rates they’d pay in emergency situations. I generally have far more electricity in my truck than I need, and I have one of my solar systems dropped directly into it, so it can hopefully power the grid and charge at the same time.

Can someone please explain this to me. I’m lost..our cars don’t generate enough electricity on their own like solar panels. So the Cybertruck is going to feed its own electricity to the grid and then what? We still have to replenish the battery. Am I missing something here?
So, there you are, you just charged up overnight and are sitting with an 80% battery.

Suddenly, there's a brownout due to a frozen manifold valve at the local natural gas auxilary power plant (tops off for that big nuclear joint down the street that can't be spun up and down all willy nilly). Oh, no!

Usually, the gas peaker plant fires up and it handles the increased load until the big plant can spin up. But, not today.

Today, your Cybertruck and others just like it, will shoulder the load as long as they can (before they reach a pre-determined "oh shit" level that you set) or until the big plant gets spun up to produce more power.

You just saved the day. Here's a dollar.

It allows cybertrucks to be used like a bunch of megapacks functioning as a peaker plant.

They'll pay more than you pay. If they didn't, nobody would help and they'd be faced with brownouts or equipment damage if the peaker plant doesn't respond to an outage or increase in demand fast enough.

It's cheaper to pay you to utilize your battery capacity than it is for them to either build and maintain another peaker plant or install a battery solution themselves.

So, you'll come out ahead in these cases. This is EXACTLY how the Megapack site works in Austrailia. Tesla buys the power, stores it, and then releases it in milliseconds when the grid needs it. They can supply power before the natural gas peaker plant can get spun up and those precious few milliseconds makes Tesla millions there.

If you have powerwall or other battery like the CT's battery, plus solar, you can store your excess panel production, Some utilities will now pay you a standby fee to act as grid backup for outages, where they could tap your battery. Yes, you will need to refill it, so this works under two conditions - where you are paid a fee for standby plus a premium kwh rate for use during a crisis, OR where you produce your own electricity.

I my case, we have the ability to sign a contract with either of our utilities that does this. However the bidirectional system from Ford/SunRun never worked so the FPL deal couldn't execute, and we await the Tesla CT software update to enable bidirectional charging with integrated storage in Maryland. This will likely get worked out, with battery-backup industrial grid leveling devices and increased use of renewables to meet growing power demand. For now it's a bit like finding nonexistent gas stations in the 1920's - eventually it will happen..

...people are being paid to participate. Usually it's quite profitable. Charge when power is plentiful on the grid, discharge during times of high need (extreme cold, heat, etc. usually). But even just charging a little extra over night, then discharging a big when you get home (everyone gets home and the grid utilization goes up usually) pays.

The Cybertruck has the equivalent of around 9 Powerwalls of energy available. (It can’t provide as much power (watts) at once as the Powerwalls do, but that’s a completely different thing.) The system would take power from the Cybertruck when there is a severe peak in energy demand on the grid—which usually lasts for only a few hours, then you can recharge later when things are back to normal, such as when nightfall arrives. (You can set things so as not to drain the battery more than you want it to, should you have any traveling to do before you have an opportunity to recharge.) You will get paid a lot more for the electricity that you sent out then for what you have to pay to recharge.)

This is the same basic functionality needed for Powerwall compatibility, but is easier/safer for Tesla to test with since the capacity of a functional grid is effectively infinite compared to the truck.

This may be a real world validation step on the road to compatibility with a single Powerwall sized system.
I agree with this. Step one on the road to Powerwall compatibility. Also, another effort to support the community and the grid which is arguably more important than extending the battery capacity of individual homes. Good news overall IMO.

Supposedly you fill up your battery at off peak rates/times , then sell back to the grid when the power is worth more. Sounds good if you’re not actually driving that day.
The only problem with that is that the UTILITIES get to control WHERE they get the power from! Right now we have 2 powerwall 3's (27 kWh's worth) and I would LOVE IT if SCE would buy the power from them, but they only do so during 'special' events, which boils down to 1 time per month from May through October via the Tesla Virtual Power Plant (VPP) we signed up for with our solar power system...
They (SCE, our utility) DOES buy our excess SOLAR power, but even though I have the PWs setup to SELL power until 9pm, it stops at around 6pm every day and PEAK time is 4-9pm, so we only get to sell them 2 hours worth of solar at 'peak' prices (55 cents per kWh)...

We could EASILY push power from he PWs out until 9pm (and then, once at 'off peak' pricing, switch back)...

In addition, we cannot charge up the PWs using 'the grid'... Must come from our Solar system... SCE doesn't allow charging them from the grid...

So, I think it's more about the UTILITIES controlling OUR power and batteries than anything else...

We had hoped we could use our solar AND battery system to 'sell at peak prices' and charge up at 'off peak' prices, but it's not 'allowed'... Otherwise, our meager 10.8 kWh system COULD make us about $100 a month or more instead of about $10 a month (plus we save about $500 vs our old power bills)... BUT at least we're at the point where our ANNUAL bill is basically 'free'... For now...

We are on NEM 2.0 (BTW) here in California... Where Power companies are Kings! NEM 2.0 basically means we get the same 'price' for power we generate as we do for using it... NEM 3.0 is WAY worse though, you only get about HALF as much... ie: you PAY 24 cents when you BUY power, but they only pay YOU 12 cents when THEY buy it from you... hardly worth it...

It doesn’t work for me with solar/generator either. So who DOES it work for?
Literally 1% of CT owners
To have a 100kw battery without being able to use it from an energy company is crazy.
Tesla really needs to step it up on V2G V2H with this MASSIVE battery

It’s so frustrating. It’s been almost 2 years I have owned the truck and over a year since I got PowerShare installed. It just sits there. I recently wrote a [snail mail] letter to Tesla asking for an update. No response.

It would make sense if it extends your home battery solar system. Where as, you prioritize charging the home batteries first thing when the sun comes up (with excess electricity) then begin charging the Truck. As night time comes, discharge the home batteries and once those are depleted, you start discharging the truck next (to your predefined limit). This process just repeats basically daily. This means you don't have to invest in 3 or 4 Powerwall's which are very pricey per Kwh of storage.

Hot summer days my 2x Powerwall's fully charged (by 11am) can only hold me off-grid until about midnight. Spring/Fall days they can provide power until the sun us up and producing power. During the 2 worst of the Winter months it wildly varies as sun is far less reliable and I can only generate about 1/2 of what I need but Net Metering assists with this.

There is value in this, at least more specifically with it being integrated into Powerwall. Perhaps the announcement while not directly stating it basically means they are finally to release that integration.

I had a deposit in for the Range Extender and they refunded it when they cancelled the product. I wanted both the Powershare and the Range Extender for different reasons. In many ways Tesla over delivered with the Cybertruck, but with Powershare and range they really underdelivered. And the wiper and the rearview mirror. I know that many here love the wiper and have no use for rearview mirrors. That is fine. These are just my opinions.
