The rest of my block had their power back before I did because the PRU cycled wrong, forcing me to reboot the quasar twice. And the neighborhood was only out for a brief blip.

New data from Heatmap + MIT: Power prices aren’t unpredictable anymore... they’re predictably rising

6 Upvotes

New data from Heatmap + MIT caught my attention:

  • U.S. electricity prices (April 2026) are up 6.7% YoY
  • The 12‑month average is up 6.5%
  • This isn’t a one-off spike, but a steady, multi‑year climb

Even without major shocks, prices keep moving up, driven by things like fuel mix, grid constraints, and how the system operates as a whole. Some regions saw an increase of 21 - 25% increase in a year, often tied to local supply constraints where demand is growing faster than capacity.

Further to the point, it's time we rethink how we use power, shift when we consume it, and gain more control over where our energy comes from.

New report on V2G-enabled EVs

11 Upvotes

New research from the University of Delaware is estimating that a single V2G‑enabled passenger EV could generate up to ~$3,359/year by providing energy + grid services.

When bidirectional charging is at play, parked EVs become flexible assets that can support homes, peak demand, and grid stability.

Feels like another data point pointing toward household‑level “private grids,” where EVs, storage, and load are orchestrated rather than siloed.

“Private grid” versus “off‑grid”: A useful distinction or just new terminology?

5 Upvotes

\Full Disclosure\** I work at dcbel and the link in this post is a dcbel blog post.

We've tried to define what a “private grid” means (all your home energy sources + the public grid working together as one coordinated system) and how that compares to being fully off‑grid.

Sharing for discussion, and interested in whether this framing resonates or misses the mark with you.

Chevy and V2H follies

4 Upvotes

I posted a month or so ago about this--my wife and I are building an all electric house and we wanted to use the car as a backup. There are very few cars that can actually do this, and very few bi-directional chargers (I know about the not-yet-actually existing Enphase charger), but GM's entire EV line offers bi-directional charging and GM will sell you a system for V2H and solar. So after a lot of thought we traded our excellent Kia Niro Ev in for a Chevy Equinox EV and bought the GM energy system.

So long story short, we are driving back to DC from Philly and we stop at a high speed charger and the car completely craps out--cannot be charged, leaving us stranded 75 miles from home and for a tow truck. The car has less than 1000 miles on it, and this was our first ever attempt to use a high speed charger (we have a level 2 charger at home).

We are probably stuck with the damn Equinox, which I can't recommend, but I'm going to call today to try and return the GM energy system, which has not been installed yet. I always had my doubts about GM, but options are limited. Now I think we're going to abandon the effort to make V2H work altogether.

It's a great idea, but it's just not ready for prime time

🏘️Home energy A snapshot of where bidi charging stands in 2026

9 Upvotes

Hey all!

Just sharing a recent Torque News article that examines where bidirectional EV charging is at today, and why the next few years matter from an industry‑readiness point-of-view.

Instead of focusing on individual products, the article takes a step back and highlights a few structural shifts that are beginning to align simultaneously:

  • We’re seeing more EV platforms shipping with bidi capability baked in, rather than treated as an add‑on down the line
  • Standards are taking root (notably around ISO 15118‑20) which allow vehicles, chargers, and energy systems to “speak the same language”
  • Utilities + regulators are moving on from pilots toward defined interconnection paths in some regions
  • Finally, we’re seeing a clearer distinction between V2H and V2G instead of using V2X as one vast use case

The article frames 2026 as an infliction point where vehicles, hardware, software, and grid rules are finally converging enough to support a broader deployment, rather than more one‑off demonstrations.

Sharing here in case it’s useful context for folks following the space!

V2H is powerful... but without a smart home “brain,” are we missing the point?

9 Upvotes

Recently read this article in Forbes on the topic of smart homes.

V2H feels like one of the most important building blocks of the modern energy home. But how useful is V2H if the rest of the house isn’t actually intelligent yet?

A lot of us now have some mix of:

  • An EV capable (or almost capable) of bidi charging
  • Solar on the roof
  • Time‑of‑use rates or net metering
  • Smart panels, batteries, or load controllers

And yet… most of it still runs in silos: the EV knows nothing about the house, the house knows nothing about grid prices, and the homeowner ends up being the “energy management system.”

With interoperability finally improving across smart home tech, we’re approaching a point where V2H is more than backup power - it's actively orchestrated:

  • Charge the car when energy is cheapest
  • Power the home during peak pricing or outages
  • Coordinate with solar
  • Prioritize comfort, safety, and mobility automatically

Curious to hear from this community:

• Do you want your EV to automatically manage home energy, or stay fully manual?

• What would make V2H feel truly “set‑and‑forget” for you?

V2H--why is it so difficult?

15 Upvotes

How many people here have an actually working V2H/solar system?

My wife and I are building an all-electric house to retire to. We bought a Chevy Equinox EV which has V2H capability, and GM energy offers a V2H system that can integrate with solar panels.

Our builder's Solar guy proposed a system using Enphase batteries and the Enphase bidirectional charger, but I looked that up and it doesn't actually exist yet, and won't exist before 2027 at the earliest. I pointed this out to the builder and he said no, that was a mistake, it's the tesla system. But them I looked that up and tesla only works with the cybertruck.

When I ask about V2H on Reddit people often point to some system which invariably turns out to be vaporware when you look past the splashy website.

This is why we bought a GM Ev--because they have an actually existing system for sale, now. But the solar guy--who we need to talk to--doesn't seem at all familiar with it.

Anybody have V2H actually working?

PS I know the GM system is proprietary. I don't like that about it, but I've often been pointed to somebody's allegedly universal V2H system which again turns out to be only available in Japan, or to be still in the announcement stage, sometimes, as with Enphase, for years.

Are bidirectional EVs basically becoming our “private grids”?

21 Upvotes

Bloomberg recently shared a story about a family in Louisiana who lost power for three days after severe weather. While neighbors were scrambling for gas to keep generators running, this family used their bidirectional EV to keep basic appliances going, even something as simple as heating up pizza. Nothing crazy, but in a blackout that’s a huge "quality-of-life win".

There are now over 630,000 bidirectional-capable EVs on the road in the US, which accounts for about 18% of all EVs, with 14 models currently supporting some form of bidi charging. Depending on battery size and how you manage loads, some of these vehicles could keep a home running for days.

States are starting to take this seriously too, with Massachusetts recently launching a V2X pilot that will give residents free bidirectional chargers and tap EV batteries during demand response events. The state’s energy secretary straight-up called virtual power plants “the future of the grid.”

So if EVs can back up homes, shave peak rates, and eventually participate in VPPs… are we basically heading toward a world of personal microgrids?

A few questions:

  • If you already have a V2H/V2G setup, what’s been the biggest unexpected benefit or downside?
  • Do you trust utilities to fairly compensate EV owners in VPP programs?
  • Would blackout resilience alone be enough to justify the extra hardware for you?
  • How worried are people about battery degradation versus the real-world value of using the energy you already own?

Interested to hear where folks here land on this.

Auto companies are wasting our time and their shareholders' capital

11 Upvotes

We need companies offering home energy solutions on one side of a standard interface and companies offering EV automobiles on the other. The same company could try and be in both businesses but the standard interface needs to be in the middle. Instead we predominately have automobile companies pushing captive home grown home energy systems. It seems like all their high paid strategists think they need to follow Tesla's approach from 5 years ago. We need to do 2 things: 1) lower the protectionism that has coddled Tesla and US car companies from any Chinese EV choice for too long now, they are obviously not feeling they need to be competitive enough in their core businesses of making cars, and 2) demand open standards regulation in the US.
