Here’s what the the US needs to do right now to upgrade the grid
Electrek spoke with former FERC commissioner and PG&E chair Nora Mead Brownell about how the US can quickly and efficiently upgrade its grid in order to get rapidly incoming wind and solar projects online faster. Here’s what she said.
Electrek: The grid is having its moment in the spotlight, but not for the right reasons. Why can’t power utilities handle the renewable energy transition?
Nora Mead Brownell: They can. But it will take some innovation. Most of the world’s transmission infrastructure was built between 40 and as much as 80 years ago, and much of it is operating well past age and design limits. Utilities currently don’t monitor their power lines for conditions that affect carrying capacity; like how much a line is sagging or swaying or ambient temperatures. In fact, 99% of power lines aren’t monitored at all, and that’s a problem.
Without that monitoring capability, utilities are making a “best-guess” as to how much power a transmission line can handle. By using assumptions that are typically “worst-case,” such as assuming extreme temperatures in July without respect to the cooling effect that wind has on a power line, utilities are only using a fraction of the true capacity of a given power line. That’s, in part, causing curtailment of renewable energy projects – and a long, often never-ending wait for renewable energy projects trying to interconnect to the grid.
Electrek: How does that delay get fixed? You mentioned innovation.
Nora Mead Brownell: In 2021, the Federal Energy Regulatory Commission (FERC) ruled unanimously to pass Order 881, which requires transmission providers to use a more accurate transmission line rating methodology called Ambient Adjusted Ratings (AAR). When fully implemented, AAR should help increase the capacity of those aging power lines and minimize the curtailment of wind and solar generation. But while Order 881 is a welcome start to modernizing the grid and increasing its carrying capacity, it’s really an incremental step, and one that’s almost three years away. It’s not enough.
Electrek: So what needs to happen?
Nora Mead Brownell: Well, we need to build more power lines. According to the US Department of Energy, we need to build about 47,000 miles of lines to meet the demand of the energy transition. But we’re dreaming if we think that’s going to happen in time to meet climate goals. Transmission lines are expensive, face considerable local opposition, and are next to impossible to permit.
If we’re to have any chance of decarbonizing the power grid before 2030, FERC needs to act again and require utilities to implement Dynamic Line Ratings. DLRs empower utilities with real-time data from advanced sensors that provide real-time field conditions that affect transmission capacity. Armed with this information, grid operators can safely go beyond – sometimes well beyond – the limits of traditional “guesstimates” to maximize grid capacity and get those wind and solar projects back online, and, hopefully, unlock some of what is now a 2-terawatt interconnection queue.
Electrek: Are utilities using DLRs now?
Nora Mead Brownell: Yes. In fact, National Grid just installed the largest DLR project in the US in upstate New York. And some of the largest utilities in the world are using it, like Xcel Energy, Dominion Energy, Avangrid, the Tennessee Valley Authority, and countless others. But given just how much wind and solar capacity the Inflation Reduction Act is poised to build, integration of the technology needs to happen much, much faster.
Electrek: So why isn’t it happening faster? What can people do to move the needle?
Nora Mead Brownell: The current economic model favors building new power lines – which, again, we need to do. But we need to better incentivize utilities to innovate with grid-enhancing technologies like DLR.
There’s currently a proposed FERC rule that would dramatically accelerate the use of the technology, and a variety of government agencies, like NYSERDA in New York, are incentivizing utilities to use DLR. In fact, New York State is arguably the leader in the expansion of its grid for renewables and the integration of the technology. National Grid, New York Power Authority, New York State Electric and Gas, and Rochester Gas & Electric are all installing DLRs provided by Boston-based LineVision’s non-contact LiDAR sensors.
People need to contact their local elected officials and demand action on this important issue.

Volkswagen has officially cancelled the long-delayed ID.7 electric sedan in America, instead focusing on selling it in Europe and China.
The ID.7 is VW’s electric mid-size sedan offering, currently available (and selling well) in Europe and also in China.
Previously the ID.7 had been intended to launch in 2024 in North America, after launching in Europe in 2023. But when launch time came close, VW delayed the North American debut of the model indefinitely last May.
As recently as October, VW America’s boss Pablo Di Si (who has since moved on) said that the ID.7 could still come in 2025.
But now we know that that indefinite delay is now fully definite: the model has been canceled in the US and Canada.
The news was broken yesterday by The Car Guide, speaking with a VW Canada representative. We’ve since reached out to VW, who confirmed the news to us.
Automotive News quoted a VW spokesperson saying the decision was made due to “the ongoing challenging EV climate.” Last year in North America, EV sales grew by 9%, faster than the overall auto market which grew at 2.5%, suggesting that the market is in fact more challenging for non-EVs than EVs at the moment. Further, gas car sales have been in long term decline since 2017, whereas EV sales have risen drastically in that time period.
That growth was achieved with very few available sedan models as well, with almost every EV available in America being an SUV-type. Adding additional model availability could open up the market to more buyers who want a right-sized vehicle instead of a land yacht.
But VW has been having a challenging time itself in the US. Until recently, it only offered a single SUV model, the ID.4, in the US. While the ID.4 has brought a lot of upgrades recently, it’s also one of the few vehicles whose sales were down in a growing market (which was true even before the stop sale which has now been lifted after fixing a door handle problem). Perhaps VW could have benefitted from offering a vehicle in a different format.
VW had previously blamed its delay of the ID.7 on “market conditions.” It didn’t specify which market conditions it was referring to, but we have some suspicions.
Manufacturers have a belief that Americans only want SUVs (or so they say – really, this is at least partially driven by emissions rules), and the ID.7 is not one. Although VW at one point did try to portray it as one – when we first saw the ID.7 it was in the guise of the “Space Vizzion” concept, and VW said it “combines the aerodynamic qualities of a Gran Turismo with the generous interior space of an SUV,” trying to leverage Americans’ supposed desire only for land yachts by portraying a somewhat more sensible wagon as something it’s not.
That said, the car likely would have been higher-priced than the ID.4, as it is in Europe. The best-selling electric sedan in the US is the Tesla Model 3, with few other options outside of the luxury market. The ID.7 could have offered an alternative for buyers who are looking for something that isn’t associated with Tesla CEO Elon Musk, but its likely high starting price might have limited that appeal.
But while this is a disappointment for those of us waiting for more right-sized electric vehicles, it doesn’t mean the end for new VW EVs in the US. Automotive News quoted a VW spokesman as saying that “electric vehicles continue to be a core part of Volkswagen’s long-term product strategy, and new electric models will continue to be introduced for this market.” So, stay tuned for more.
Well, if you still want an electric VW, there’s always the ID.4. To contact a local dealer and see if they have any VW ID.4s ready to sell, feel free to use our link. You can also reach out about the ID.Buzz, if a quirky electric minivan is more your speed.
