This story is part of CNBC’s “Transmission Troubles” series, an inside look at why the aging electrical grid in the U.S. is struggling to keep up, how it’s being improved, and why it’s so vital to fighting climate change.

Building large-scale transmission lines that carry electricity across the United States has the potential to be an extremely cost-effective way to reduce greenhouse gas emissions while also improving reliability of the country’s energy grid.

But the energy grid in the U.S. has developed over decades as a patchwork of thousands of individual utilities serving their own local regions. There is no incentive for energy companies to see the forest for the trees.

“The system we have for planning and paying for new transmission does not adequately value or promote the vital benefits of interregional transmission. Transmission planning does not sufficiently take into account the benefits of a holistic system over the long term,” Gregory Wetstone, CEO of the non-profit American Council on Renewable Energy, told CNBC.

The regulatory framework that has evolved surrounding those local utilities and their electricity transmission processes completely short-circuits when it comes to planning longer, bigger-scale transmission lines.

“Lines crossing multiple states have to receive permits from many local and state agencies, and a single county can block the construction of a new transmission line that would benefit the entire region,” Wetstone told CNBC. “Imagine trying to build the national highway system that we now have if any single county along the way could block the entire project. It simply wouldn’t have been possible.”

The Department of Energy is in the process of conducting a National Transmission Planning Study,to look into all of this. The government’s Pacific Northwest National Laboratory and its National Renewable Energy Laboratory are working on executing that work, but the results of that study will not be published for some time, a NREL researcher told CNBC.

Unless the U.S. can modernize its electric grid and update the regulatory processes surrounding construction of new lines, the country’s climate goals will be harder and more expensive to achieve.

Why a macro-grid is a cost-effective climate win

Currently, electricity generation results in 32 percent of carbon dioxide emissions in the United States .To mitigate the effects of global warming, electrical generation needs needs to move from burning fossil fuels, like oil and coal, to emissions-free sources of energy, like wind and solar.

One way of reducing emissions caused by electricity is to build as much clean energy generation as close as possible near to where the electricity is needed.

But building longer transmission lines, to carry wind and solar power from regions where those resources are abundant to the places where demand is highest, would actually be a cheaper way of reducing emissions.

“Multi-regional transmission designs enable the highest reduction in cost per unit of emissions reduction,” James McCalley, an electrical engineering professor at Iowa State University, told CNBC.

There are three reasons why:

Tapping into the most abundant resources. First, large-scale, multi-regional transmission lines — often called a “macro grid” — would connect the most powerful renewable energy sources with the highest demand centers, McCalley said.

“Many mid-U.S. states have excellent wind resources, and the southwest U.S. has excellent solar resources, but the population is insufficient to use them,” McCalley told CNBC. “Population density rises as you get closer to the coasts. Transmission lets you build rich resources and use them at the heaviest load centers.”

Heavy electrical transmission lines at the powerful Ivanpah Solar Electric Generating System, located in California’s Mojave Desert at the base of Clark Mountain and just south of this stateline community on Interstate 15, are viewed on July 15, 2022 near Primm, Nevada. The Ivanpah system consists of three solar thermal power plants and 173,500 heliostats (mirrors) on 3,500 acres and features a gross capacity of 392 megawatts (MW).

Balancing supply with demand over time zones and seasons. Second, transmission lines that span time zones would let the most effective power generating resources go to the region that needs the power when it needs it. “During the course of a 24 hour period, regions in different time zones peak at different times, and so the best resources in one non-peaking region and be used to supply demand at another peaking region,” McCalley told CNBC.

Similarly, large scale transmission would allow regions to share power generation to meet their annual capacity needs.

“Regions today require that they have total installed capacity equal to about 1.15 times their annual peak load. But the annual peak load occurs at different times of the year for different regions. So multi-regional transmission would enable sharing of capacity,” McCalley told CNBC.

For example, the Pacific Northwest peaks in energy demand in early spring and the Midwest peaks during summer months. They could, if connected, borrow from each other, “enabling each region to avoid constructing new capacity,” McCalley said.

Better reliability. Finally, improved energy sharing would also lead to a more reliable energy grid for consumers.

“After decades of underinvestment, our current grid is ill-equipped to handle the energy transition or increasingly frequent severe weather events,” Wetstone told CNBC. So in addition to making clean energy available cheaply, “a macro grid would also allow for the transfer of energy to prevent blackouts and price spikes during extreme weather events,” Wetstone said.

A 2021 NREL study, “Interconnections Seam Study,” found benefit-to-cost ratios that reach as high as 2.5, meaning for each dollar invested in transmission that connects the major components of the U.S. power grid — the Western Interconnection, the Eastern Interconnection, and the Electric Reliability Council of Texas — would return up to $2.50. 

Here is a visualization from the National Renewable Energy Lab’s “Interconnections Seam Study” showing how transmission lines that connect the major regions of the U.S. power system could allow the US to access more renewable energy and allow regions to balance energy demand.

Why the US does not have a macro, cross-regional grid

“Who pays for transmission I think is the biggest problem,” Rob Gramlich, the founder of the transmission policy company Grid Strategies, told CNBC. “It’s a freaking mess,” he said.

Currently, transmission lines that are constructed in the U.S. have to go through a years-long planning, approval and regulatory process where all of the utilities, regulators and landowners determine who benefits and how much each beneficiary should pay.

“Figuring out how to share costs among the many parties that would benefit from (and be impacted by) new transmission can be contentious, as can navigating permitting processes at the county, state, and federal levels along new routes,” explains Patrick Brown, a researcher working on transmission issues at the NREL.

In addition, local stakeholders often dig in their heels in when a new transmission line has the potential to undercut their existing business.

“The majority of new transmission is built for local needs and disconnected from any regional or interregional planning. Not surprisingly, the owners of these local projects seek to protect their transmission and generation earnings from being reduced by less expensive renewable resources that would be brought onto the grid as a result of interregional transmission,” Wetstone told CNBC. “So the broader societal benefits of a larger and more resilient grid are often ignored.”

It will be especially challenging to determine exactly who benefits exactly how much for a transmission line that spans the entire country.

“The system in and of itself is a benefit to the nation,” McCalley told CNBC. “The principle of ‘beneficiaries pay’ is harder to implement in that case.” So there’s no clear answer yet on how a macrogrid line would be paid for.

“My view has been the federal government, in concert with state government, in concert with developers — that it’s got to be a coordinated, complementary division of funds somehow, between those three, and whether it’s 95-5, or 30-30-40 percentage, I don’t know,” McCalley said.

For example, the larger utility companies in the US (like PG&E, American Electric Power Company, Duke Energy, or Dominion) could partner with the companies that make this kind of transmission technology, and with federal power authorities (like the Bonneville Power Administration, Western Area Power Administration, Southeastern Power Administration and Southwestern Power Administration) to coordinate a macro-grid construction project, McCalley said.

The cooling towers at the Stanton Energy Center, a coal-fired power plant in Orlando, are seen near electrical transmission towers. The facility is projected to convert from burning coal to using natural gas by 2027. U.N. climate talks ended on November 13, 2021 with a deal that for the first time targeted fossil fuels as the key driver of global warming, even as coal-reliant countries lobbed last-minute objections.

‘Get them in one room’

Despite the current morass of planning and building transmission lines in the U.S., “there are also many ways to overcome these barriers,” Brown at NREL told CNBC.

“Existing rights-of-way can be reused; new federal guidelines could encourage proactive interregional planning and coordination and help identify the highest-priority expansion options; and public engagement and community ownership can help get local stakeholders onboard.”

Regulators ought to be forced to work together, according to Konstantin Staschus, who has been working with transmission for his entire career, both in the U.S. and in Europe.

When the Midcontinent Independent System Operator, one of seven regional planning agencies in the United States, plans transmission line construction plans, it starts with a massive meeting. At the kickoff for its next round of transmission planning, MISO had a three hour planning meeting with 377 people in the meeting.

In the same way all of those stakeholders are pushed together to hash out their differences, so too should that happen for larger scale planning, according to Staschus, who was the Secretary-General of Europe’s transmission planning body, the European Network of Transmission System Operators for Electricity, for the first eight years of the regulatory body’s existence, from 2009 to early 2017.

“Get them in one room. Make them plan nationally. Make them redo it every year,” Staschus told CNBC.

“If they do that and if they’re experts — scratch their heads for months, figure out all the data and argue about the assumptions and the cost allocation, and they come with a proposal to their own management and convince them and then the management goes together to the various regulators and convinced them,” then the U.S. will be on a better path, Staschus told CNBC.

“But if you don’t treat it like a countrywide system, you won’t start this process.”

For Johnson of MISO, though, these kinds of idealistic discussions of building a national system come from people who don’t truly understand the challenge of getting a transmission line built even on a regional basis. For instance, the lines might run through entire states that don’t pull energy from that system.

“Those things are going to be far more complicated than what people are aware,” Johnson said. The challenge is not designing a transmission line, Johnson says, the challenge is determining who benefits how much and how much they have to pay.

What Johnson sees as more likely is stronger connections at the seams from one planning region to another. “I think of it kind of like a bucket brigade,” Johnson said, where one region can more seamlessly share power with its next door neighbor.

Jesse Jenkins, who is Princeton professor and a macro-scale energy systems engineer, says that while national-level grids are attractive, these interregional grids are essential.

“I don’t think we necessarily need a continent-scale macro grid, although there are plenty of studies showing the benefits of a such a ‘interstate highways’ system for transmission, so it would be nice to have,” Jenkins said. “What we absolutely need is a substantial increase in key inter-regional long-distance transmission routes. So it’s not all local lines (e.g. within single states). We need a lot of new or expanded/reconductored multi-state corridors as well.”

If the US can’t get national lines built, then interregional lines are better than nothing, agrees McCalley. But emissions reductions will remain more expensive than if we built a national grid.

“If we rely on what we have done in the past, it would be really hard because every state weighs in, and every state gets veto power, essentially. And so that won’t work,” McCalley said.

Rivian R1 Quad kick turns into the new EV Halo car brand

Rivian R1 Quad kick turns into the new EV Halo car brand

Rivian R1T Quad

Rivian flew us out to Lake Tahoe to show off the crazy capabilities of its new quad-motor powertrain on both its R1T pickup truck and R1S SUV. Rivian’s original R1S and R1T were quad-motor vehicles, but as of the second generation of the R1 platform, only dual and tri-motor variants existed. So why quad? Why now?

First of all, let’s get the specs out of the way. The new Rivian Quad is a beast, all the way from its $120,000 price tag to its over 1,000 horsepower and 1200 lb-ft torque.

  • Prices for R1T start at $115,990 USD / $190,990 CAD and the R1S starts at $121,990 USD / $201,990 CAD – Deliveries begin summer 2025
  • Launch Edition R1T starts at $119,990 USD / $196,990 CAD and Launch Edition R1S starts at $125,990 USD / $207,990 CAD. Rivian is reintroducing Launch Edition for the Gen 2 Quad, celebrating the configuration that first defined our commitment to all-electric performance and adventure.
  • Destination and freight charge is $1,895 USD / $2 ,695 CAD
  • Powertrain: Horsepower: 1,025 hp Torque: 1,198 lb.-ft.
  • Performance 0 – 60 MPH 2 .5 sec R1T, 2 .6 sec R1S, ¼ Mile Time 10.5 sec, VMax 130mph
  • Range: EPA-estimated up to 3 74 miles of range (Up to 400 miles in Conserve mode)
  • Charge Port: NACS (North American Charging Standard)

How does one characterize this massive spec monster in the larger vehicle landscape? Before we try to get our head around that, there is more.

The Rivian R1 Quad brings back tank turn as a new feature: Kick Turn – And it is actually useful.

Advertisement – scroll for more content

From our history books, we know that one of the features that the original R1 Quads touted was the ability to turn in a circle/spin on its axis by having its right side wheels spin one way and its left side wheels spin the other. While the ‘tank turn’ disappointingly never made it to the original production vehicles, Rivian hadn’t let go of the idea.

Kick Turn.

The New R1 Quads bring back the ability to turn/spin on a dime when offroading. However, this isn’t just a parlor trick. It is actually useful when negotiating tight switchbacks.

Here’s what it is like to invoke the “Kick Turn” from inside the vehicle. Unintuitively, you don’t want to turn the steering wheel. Instead, you simultaneously push both steering wheel buttons in the direction you want to turn.

The same maneuver from behind:

I was able to use and master the kick turn pretty quickly after trying it for the first time and it is sooooo fun….and useful. Rivian says that the kick turn should only be done on gravel and loose dirt. But I could see ejecting out of a parallel parking spot with this feature…or doing a U-Turn on a country road.

I imagine the wear on the tires that are already taking a beating from this super heavy vehicle doing 2.5 second 0-60s is massive. Rivian says that the standard tires are guaranteed for 30,000 miles but imagine that loses a few miles every time a kick turn is invoked.

Perhaps most devestating, the original Rivian Quads won’t get the Kick Turn functionality. As an owner who was excited about the tank turn functionality when making my buying decision, I’m not pleased. Rivian says that the controllers for the original Quad Motors aren’t tuned and accurate enough to master the move. I’m ready to sign a petition that Rivian try anyway.

Quad offers four different wheel and tire options:

  • 22” Super Sport
  • 22” Sport Burnished Bronze
  • 20” All-Terrain Dark
  • 20” Dune Satin Graphite All-Terrain

Also, there will be Launch Editions:

Rivian is reintroducing Launch Edition for the Gen 2 Quad, celebrating the configuration that first defined our commitment to all-electric performance and adventure. The new Launch Edition Quad will feature an exclusive “Launch Edition” IP badge and a suite of special features, including:
Two standard colorways:

  • Launch Edition exclusive: the return of Launch Green paint with Black Mountain + Brown
    Ash Wood interior
  • Storm Blue paint with Slate Sky + Walnut Wood interior
    Additional included features:
  • Lifetime Rivian Autonomy Platform+
  • Lifetime Connect+
  • Camp Speaker
  • Gen 2 Key fob

NACS native

One more nice thing about the Rivian R1 Quad is that it is the first Rivians, and one of the first non-Teslas overall, to have the NACS port standard. This allows the vehicle to charge at most Tesla chargers without adapter. The flip side however is that it will need the included CCS adapter to charge at most other network charging stations including Rivian’s own RAN charging network, at least until the networks and Rivian switch their chargers over to NACS. We had success on a V4 Supercharger near Lake Tahoe but obviously weren’t able to test the charging speed or charging curve since the vehicles we were given started at 80%.

One other nice trick is that the Quad has a control panel that allows the driver to make their own drive modes.

RAD Tuner (exclusively on Quad, coming in September): Developed by the Rivian Adventure Department, a team of engineers, software developers and designers who create and test features that push the boundaries of our vehicles.

Rivian drivers will have better control over their vehicle’s dynamic behavior. Through intuitive sliders, you can fine-tune ride handling while creating personalized and savable drive modes.

Start from scratch or build upon presets like “Rally” or “Sport.” There are even preset modes that were born from real-world triumphs:

Desert Rally mode was meticulously engineered during the 2023 Rebelle Rally, a grueling competition where the R1T made history as the first fully-electric vehicle to ever win

Hill Climb mode was honed at the legendary Pikes Peak International Hill Climb, where
in 2024, our R1T conquered the race as the fastest production truck to ever make the
ascent.

Oh and Rivian now lets you record Launch Mode with Launch Cam so those 2.5 second 0-60s where you beat the Ferrari off the line can now be downloaded and shared with friends on social media. The videos include real-time stats like speed and distance overlays. Unfortunately Rivian no longer includes an interior camera to capture passengers’ reactions.

Electrek’s take

At a starting price near $120K and realistically over that with some bells and whistles, the Rivian R1 Quad vehicles aren’t going to have mass appeal. In fact, I don’t think these will even be Rivian’s top sells since the $80,000 Rivian vehicles with dual motors are almost as good (and better on efficiency).

However, Rivian is really trying to build its brand ahead of the R2 launch and this vehicle is as adventurous as it gets, electric or otherwise. Think about it: This is a 7-seat, off roading monster that will beat almost any supercar off the line…and can now spin on a dime.

Kia reveals the sleek new EV5 for Europe with up to 329 miles range

Kia-EV5-Europe

Kia is entering Europe’s most competitive EV segment with the upgraded EV5. It’s slightly smaller than the Tesla Model Y, but Kia says the EV5 is “a cornerstone” to its growth strategy in Europe.

Kia EV5 lands in Europe

After launching the EV5 in China in November 2023, Kia’s electric SUV quickly became a hit. It’s already leading Kia’s comeback in the world’s largest EV market.

Although Kia has introduced the EV5 in other markets, including Australia and New Zealand, this is the first time it has revealed specs for the upgraded version specifically designed for Europe.

The upgraded EV5 is powered by an 81.4 kWh battery offering up to 329 miles of WLTP range. Unlike the Chinese version, which uses a BYD LFP Blade battery, the European version features a nickel-manganese-cobalt battery pack.

It will be available in baseline and GT-line models. All EV5 variants can recharge from 10% to 80% in as little as 30 minutes.

Both variants are offered in FWD with up to 215 hp (160 kW) and 218 lb-ft (295 Nm) of torque. Kia’s electric SUV also includes bi-directional charging, including vehicle-to-load (V2L) with up to 3.6 kW of power.

The exterior remains essentially unchanged from the version sold in China, featuring an upright stance similar to that of the larger EV9.

The European-spec EV5 measures 4,610 mm in length, 1,875 mm in width, and 1,675 mm in height, which is slightly smaller than the Tesla Model Y. It’s closer in size to the Hyundai IONIQ 5.

Inside, the EV5 “creates a lounge-like environment” with comfort-focused seats that include massage functions, heating, and ventilation.

The interior is centered around Kia’s new ccNC (connect car Navigation Cockpit) infotainment system. The setup includes dual 12.3″ driver clusters and infotainment screens in a panoramic display, plus a 5.3″ climate control display.

Kia will build the upgraded EV5 for Europe in Korea, unlike the Chinese version, which is produced by its joint venture Kia Yueda.

Although prices have yet to be confirmed, the EV5 will sit between the EV3 and EV6 in Kia’s lineup. Given the EV4 starts at £34,695 ($47,700) and the EV6 is priced from £39,235 ($53,200), the EV5 is expected to start at below £40,000 ($55,000) in the UK.

Sjoerd Knipping, Kia Europe’s COO, said that “The EV5 is a cornerstone of Kia’s European growth strategy.” He added that the electric SUV is “tailored to the way Europeans live, work, and drive.”

Kia has already confirmed the EV5 will be sold in other global markets, including Canada. However, it will not arrive in the US.

The company said it will launch the EV5 “exclusively for the Canadian market” in North America. It will be available with FWD and AWD powertrains, as well as two battery sizes: 60.3 kWh and 81.4 kWh, offering a range of up to 310 miles (500 km).

What do you think of Kia’s new electric SUV? Would you buy one over the Tesla Model Y or the Hyundai IONIQ 5? Let us know in the comments.
