As yet another heat wave shattered temperature records in the Pacific Northwest in mid-2021, threats of rolling blackouts rippled throughout the region.
These recurring extreme weather threats offer a sobering reminder that aging energy grids weren’t designed to handle the stress of climate change. Nor were they designed to withstand the energy impact from extreme events like heat waves, droughts, or wildfires, which are predicted to become more frequent and intense, according to Pacific Northwest National Laboratory’s (PNNL’s)Nathalie Voisin, a PNNL Earth scientist who is part of a team working on grid resilience in relation to climate change.
“Even under modest climate change projections, threats of power shortfalls will become more common,” said Voisin.
To relieve some of that pressure, research teams at PNNL are focused on prevention. They are working to predict future drought scenarios and create hydropower and grid contingency plans, implement smart electricity load controls, manage forests to reduce the impact of wildfire, and place new grid infrastructure, like energy storage or microgrids, where they are needed most.
“When we’re talking about power shortfalls, even small steps add up. Shifting large appliance use, like a high amount of dishwashers or washing machines, from afternoon and evening peak hours to the morning or the night, or increasing thermostats a couple degrees in the summer and using ceiling or floor fans can make a difference,” said PNNL’s Dhruv Bhatnagar, an energy systems engineer.
What high temperatures mean for hydropower
The early summer heat wave of 2021 led to a spike in energy demand that left hydroelectric dam operators with a difficult choice: (1) use water to keep up with the surge, leaving less water for late summer, or (2) buy energy on the open market, often at higher prices and from natural gas.
PNNL modelers like Voisin are working to predict these types of events and the impacts to generation and load, including short-term issues like heat waves or longer-term issues like droughts via efforts like the Department of Energy’s HydroWIRES initiative.

PNNL researchers are using advanced modeling to predict droughts and provide grid operators with information for decisions on how to allocate power during extreme events. For instance, to simulate the impact of climate change on the future power grid, researchers used a computer model called GENESYS. Recent results showed that power systems will be affected by multiple stressors simultaneously, and these impacts compound and aren’t just additive.
PNNL is developing drought scenarios to help operators and regulatory agencies with future planning. This includes predicting future drought conditions and the impacts on hydropower and thermoelectric plants, which can then be used to understand the potential impact on grid operations and guide adaptation.
“This information is used to help operators make risk-informed decisions and determine where vulnerabilities may lie. Ultimately, it will help answer the question—given different stressors, will there be enough power to meet the demand and other power grid needs?” said Voisin.

Recently, Voisin and her team evaluated how hydropower operations vary seasonally and annually depending on water availability for the Chelan Public Utility District. For example, they demonstrated that even during a dry summer, when hydropower’s overall generation is limited by low water availability, hydropower maintains its flexibility to support the peak load under extreme events. This highlights the need to better consider the range of services that hydropower can provide to address the resilience of the grid under extreme events.
Wildfire and hydropower
During an above-normal fire season, like what is currently occurring in California, there will likely be impacts on the grid, either through intentional shutoffs to reduce fire risk or loss of infrastructure due to the fire itself.
“The idea is not to stop all wildfires but to work in advance to reduce their risk, and predict areas that are more prone to them,” said PNNL’s Mark Wigmosta, a PNNL environmental engineer. Wigmosta’s work focuses on forest thinning and restoration with the goal of less fuel for fires.

Reducing fuel load in highly dense forests may leave more water in streams and can lead to higher, longer-lasting snowpack. This may produce more water throughout the summer dry season.
“This may provide a way to get more water into the system, depending on location,” said Wigmosta. Another grid benefit is that weaker fires are likely to burn less energy infrastructure. For example, between 2000 and 2016, wildfires caused at least $700 million in damages to 40 transmission lines in California. Nationwide costs from wildfires are significantly higher.
After fires burn, there is typically an increase in runoff and sedimentation. Sediment flows downstream, builds up in reservoirs, and “isn’t great for infrastructure, including turbines,” said Wigmosta. Prescribed burns or tree thinning can actually increase flow volumes and improve hydropower operations. And, weaker fires will have less of a negative impact on infrastructure and the grid.
Backup or autonomous power sources also offer promise, particularly during emergency situations. Microgrids are self-contained grids that can power key areas, such as hospitals or police stations, during power shortfalls that could occur during extreme events like a wildfire or hurricane. PNNL’s Microgrid Component Optimization for Resilience tool helps streamline the design process for microgrids with the goal of simulating power under a variety of outage conditions.
PNNL is also taking a leadership role in developing new technologies for grid-scale energy storage, which includes a new generation of battery materials and systems and other forms of energy storage. For example, current grid-scale energy storage systems such as pumped storage hydropower use pumps to move water uphill to store renewable energy when demand is low and generate power when demands are high as water flows downhill. PNNL has been working on incremental steps with pumped storage, such as evaluating environmental impacts of newer systems, to enhance future grid resilience or working with international stakeholders to identify strategies to finance and develop new projects. Even concepts like pairing batteries with hydropower are being explored to enhance hydropower’s capabilities and assure reliability during power shortages while reducing environmental impacts.
“Ultimately, we want to prepare for extreme events. Whether it’s through technological innovation, enhancing grid resilience, or supporting long-term planning. We take a holistic approach to tackling these big, long-term challenges to support risk-informed decision-making,” said Voisin.

From the ashes of Elon Musk’s decision to fire the whole Supercharger team last year, a new company has risen: Hubber, which will take its founders’ expertise at setting up Tesla Superchargers and apply that to addressing the lack of high-speed urban charging for taxis and other commercial vehicles.
In the immediate aftermath of this decision, a lot of questions were asked around the industry – and a lot of companies started snatching up talent from the best EV charging team in the world.
Or, alternately, some of that talent went to form their own companies. That’s the case for Harry Fox, Connor Selwood and Hugh Leckie, who met at Tesla and together oversaw the rollout of 100 Supercharger sites with 1,200 total chargers across the UK & Ireland. And after the shakeup of the Supercharger team, they set off to charge a new path of their own.

The three formed Hubber, which pitches itself as a new type of EV charging company, focused on solving “the urban charging gap.”
Hubber describes itself as “the UK’s leading specialist in urban high-powered EV charging, addressing one of the most urgent constraints in the energy transition: the shortage of fast, reliable charging in major cities.” It “acquires and develops prime urban sites into large-scale charging hubs, combining deep grid-connection know-how with a proven ability to deliver complex infrastructure at speed”.
A large amount of the traffic in UK cities is taken up by taxis and last-mile, and these vehicles tend to see higher utilization than commuter cars, so they need to charge more often. Hubber says that taxis charge five times as often as a private vehicle, which means they’ll need more access to fast EV charging.
This is further exacerbated in urban environments, where EVs might not park in a place they can charge. Lots of urban homes don’t have garages, and while there are street EV chargers available in London, they’re not everywhere yet. So convenient fast charging is essential.
And the needs for commercial drivers are different than those of other commuters. While nicely-appointed charging plazas (like Rove’s “full service” EV charger in Santa Ana, CA) are great for the average consumer, commercial EV drivers put more of a premium on speed and affordability, and don’t mind if a site is a little further off of a main thoroughfare, or not as close to food or shopping as other drivers might want.
So Hubber is looking at sites that other developers might pass over – like old warehouses or gas stations – and figuring out how to turn them into an ideal site for high-throughput charging.
With its cofounders’ experience at Tesla, Hubber will buy sites, transform them into a charger-ready location, and essentially provide the dream location that they would have liked to see during the site selection processes they went through in their previous jobs.
The charging hubs could still have some amenities, like restrooms and vending machines, of the type that would be useful for taxi or ride-hailing drivers to grab during a quick stop. But the main focus would be on getting people in and out and back on the road.
Here’s a rendering of what a potential site might look like. In this sample location, there would be room for light-duty vehicles up front, with an area for larger last-mile delivery vehicles with larger charging bays. A small covered area could provide restrooms and vending, and another portion of the site could be dedicated to transformers, batteries and the like.
Hubber is also thinking ahead to a possible autonomous future, where driverless ride-hailing vehicles like those from Waymo could have a place to charge. Although given that there aren’t currently great solutions for autonomous charging, an attendant might have to be involved for the foreseeable future.
The company would also like to expand beyond the UK and Ireland, but they’re sticking to home base for the time being. After all, things are just getting off the ground – but the £60 million (~$81m) investment that Hubber just secured is certainly a big boost towards getting the project moving.
Speaking of projects, Hubber’s first facility is opening this coming week, on August 20th. The site is at Forest Hill in South London, near Forest Hill Station. It will have 12 EV charging bays, with 3 150kW and 3 300kW dual-head chargers. The site will be operated by RAW charging, which will offer free fast charging for its first week of operation.
The silver lining, at least for the rest of the industry, is that it allowed this talent to be distributed around to other companies. This isn’t beneficial for Tesla and did cause chaos which has likely affected the rollout of NACS, slowed EV charging site development in the US, and so on, but it has been beneficial for other companies who managed to snatch up talent.
Or, for companies like Hubber, which were formed by that talent.
It’s an interesting idea, and I like the angle of focusing on taxis in order to increase utilization of the site. EV charging is potentially an interesting business long term, but currently a lot of chargers see low usage because it’s so easy for most of the people who own EVs to charge at home.
But we’re going to have to move beyond the market of people who can easily charge in a garage attached to a single family home, especially in cities. Getting an easy way for the cars that get used the most in a city to charge is a really important move, and we’re looking forward to seeing how Hubber can help with this. And having a leadership team consisting of people who formerly worked at the best charging team in the industry isn’t a bad start.

Indian ag and automaker Mahindra has launched a limited-run Batman Edition of its BE 6 Electric Origin SUV, calling it, “a production car that brings to life a rare fusion of cinematic heritage and modern luxury, inspired by Christopher Nolan’s critically acclaimed The Dark Knight Trilogy from Warner Bros. Pictures.”
And, you guys – the new Mahindra BE 6 is. So. Serious.
Someone at Mahindra is very taken with American culture it seems. After launching the Willys MB Jeep-inspired Mahindra Roxor a few years ago, the company followed it up by building a credible line of EVs co-developed with VW. Now, they’re building a limited edition of one of those EVs inspired by another American cultural icon.
“Batman is more than a pop-culture icon — he represents innovation, resilience, and an unyielding drive to push boundaries,” says Vikram Sharma, Senior Vice President, Warner Bros. Discovery Global Consumer Products, APAC. “This collaboration brings that spirit to the road in a bold, electric way. With this limited-edition range, fans in India can now experience the thrill of Batman every time they drive. It’s a collector’s statement on wheels.”

Despite all the Batman branding, the end result is almost tasteful. I could do without the custom Batman decal on the front quarter panels, but the rest of the mods are far less offensive. I even like the little “Bat Signal” puddle lights on the wing mirrors.
Mahindra Batman BE 6
As a car, the special edition Batman Mahindra is based on the top-shelf version of the BE 6, fitted with a 79 kWh battery good for 550 km (about 340 miles) of range according to its WLTP rating. That battery sends power to a rear-mounted 282 hp (210 kW / 286 PS) electric motor generating and 380 Nm (about 280 lb-ft) of torque that sends power to the rear wheels.
The BE6 also features a modern Level 2 ADAS tech and screens everywhere, including in the steering wheel hub – which seems like it might get particularly nasty in an airbag deployment (but no one asked me).
Pricing starts at ₹27.79 lakh (a little under $27,500, as I type this), and production will be limited to just 300 units. Order books are set to open 23AUG.

Electric bike and scooter safety is now part of the curriculum in some schools – and surprisingly, it’s happening in Florida.
Yes, Florida. The state that’s better known for keeping education out of schools, banning everything from books to the word “gay.” But now, a Central Florida nonprofit is stepping in to make sure students are at least learning how to ride responsibly.
The group Best Foot Forward for Pedestrian Safety has partnered with local police departments and Orange County Public Schools to bring e-bike and e-scooter safety programs directly into middle schools and high schools. The initiative is focused on addressing the growing number of crashes and injuries involving students riding electric two-wheelers.
The safety course covers basics like wearing helmets, obeying traffic laws, and making yourself visible to drivers — skills that are important for the many young riders who are increasingly taking to electric bikes as a form of independent transportation around their cities and neighborhoods. One of the main topics of the program is said to be speed management. The program addresses the importance of keeping speeds reasonable and the impacts of faster riding.

Like much of the US, Florida has seen a surge in e-bike and e-scooter popularity among kids and teens, especially in suburban and coastal areas. While many embrace them as a fun and fast way to get around, the sudden rise has also come with a worrying spike in injuries and deaths, prompting calls for improvements in both infrastructure and education.
With e-bike usage exploding across the US, more schools and communities are exploring steps to increase rider education. It’s a sign that America’s transportation habits are changing – and our education systems are beginning to catch up.
Electrek’s Take
I think programs like this are great because they teach kids things that they’d otherwise have to learn through trial and error. We don’t just hand cars to sixteen-year-olds and say, “figure it out.” So it follows that some form of organized rider education would be important as more youths take to e-bikes than ever before.
In cycling-intensive cities in Europe, all schools teach kids to ride bikes, often giving the kids some form of cute little cycling diploma to demonstrate that they’ve passed the course and can safely ride a bike.
But at the same time, this makes me wonder if we’re still missing the point. Responding to an increase in e-bike rider deaths with lessons about bicycle speed management is a bit like responding to mass shootings by lecturing innocent passersby about why they shouldn’t run into bullets.
Educating riders is always great and I’ll always support it. But in parallel, perhaps we should also be addressing the root cause of all of these tragics deaths. At the end of the day, most electric bike-related deaths aren’t a result of an e-bike rider doing too much fast riding; they’re a result of a car driver doing too much running over a cyclist.
