As the brutal heat wave in Texas continues, Electrek spoke with Julia Souder, CEO of the global nonprofit Long Duration Energy Storage Council, about how big battery storage is helping to keep the Texas grid online.
Electrek: How is big battery storage helping to keep the Texas grid up and running in the extreme heat?
Texas is experiencing another historic heat wave. Solar, wind, and batteries are critical for keeping the lights on by providing the power, flexibility, and stability to keep the grid running effectively.
In recent weeks, the ERCOT energy grid has seen a peak in demand, from the drawing down of 81,000 MW of power, surpassing the previous record in winter 2021. However, unlike those winter storms that left millions without power, the grid in Texas has not yet had a blackout because of the recent scaling of renewable energy and energy storage that provides clean power as gas and coal plants were taken offline.
When long-duration energy storage (LDES) is paired with renewable energy, critical applications can stay online during times of extreme strain on the grid. LDES provides the flexibility, resiliency, and reliability needed to ensure the power stays on for hours, days, and even longer.
Electrek: To what extent is big battery storage being used in Texas, and why is it successful (or not)?
While there are LDES pilots in the works in Texas, at the moment, there is not much LDES deployed at scale – and this is the problem. As more renewable energy comes online to help decarbonize and electrify communities, LDES is needed to provide flexibility during peak demand periods over multiple hours, days, and seasons to ensure a reliable source of power where energy shifting is necessary.
LDES is already supporting energy systems abroad, and the LDES Council anticipates a scale of up to 600 GW by 2040 in the US, aligning with the recommendations in the US Department of Energy’s Liftoff report on long-duration energy storage.
Electrek: How are policy and regulation key for LDES expansion, and what happens if a state’s legislature passes laws in favor of fossil fuels over clean energy and LDES?
Over the next five years, Texas is expected to account for nearly a quarter of US grid-scale batteries. Policy to support and expand this growth is critical. Key decision-makers must consider setting an LDES target to spur market growth and provide certainty. Texas can use LDES tax incentives as well as create a road map for developers and investors to bring a multitude of LDES benefits, including cost savings, to communities.
Acknowledging the benefits of LDES is also critical, including capacity value, grid support, and ancillary services. Some LDES technologies can be added to the grid without complicated permitting, while other LDES projects will benefit from streamlining and simplifying permitting processes. Doing so will see much-needed acceleration.
Texas leadership must push forward strong policies supporting the diverse LDES technologies that service many aspects of the Texas economy.
Electrek: What is the LDES market going to look like in the future?
The LDES market has huge opportunities for growth. However, it’s more than a power generation asset; it’s also a transmission asset. Where transmission and distribution lines are too congested, LDES will provide relief, as well as defer costs.
Texas is currently leading the way for utility-scale solar installation that will need LDES in order to ensure there is 24/7 clean power and cost reductions. It’s essential to the clean energy transition, and now is the time to support its deployment and ensure the removal of barriers that could prevent LDES from being used to its full potential.
Julia Souder is the CEO of the Long Duration Energy Storage Council. She has over 22 years of experience in the energy and environmental sectors. She has been a longtime advocate of clean energy technology, working extensively to support environmentally friendly technologies and equitable policies. Previously she held senior positions at the LDES Association of California, National Resources Defense Council (NRDC), Clean Line Energy Partners, the North American Electric Reliability Corporation, the US Department of Energy (DOE), and as an entrepreneur at JAS Energies LLC.

Mercedes-Benz is saying goodbye to its capable, seven-passenger EQB electric vehicle – but that doesn’t mean it’s over. If you’ve been eyeing a new, quasi-affordable SUV with nationwide dealer support and a luxury logo, the time is now.
German-language Mercedes fansite JESMB is reporting that Mercedes-Benz has removed the EQB from its dealer configurator page, and the company’s Hungarian plant in Kecskemét will only produce new EQBs that have already been ordered until production of the new-look Mercedes GLB “with EQ technology” begins in 2026.
A quick search reveals that dealers are pushing hard to unload their existing stock of Mercedes EQBs. Mercedes-Benz of North Olmsted in Ohio (home of Benzs and Bowties’ Doug Horner), for example, recently advertised a new EQB with an MSRP of $59,300 with a $9,000 manufacturer incentive plus a $4,744 dealer discount. That’s more than 23% off the EV’s original sticker price and, at $45,556, is well below the $48,841 average transaction price for new vehicles in July.
MBZNO sold that car, and they’re not alone. CarsDirect has reported up to $14,500 in total Mercedes-Benz lease incentives for some EQB lease programs in select markets while TrueCar reports an average 15.6% average savings (!) off MSRP.

For that money, Mercedes’ EQB customers get a capable, mid-sized SUV with room for five adults and two kids in (what my family has come to call) “the wayback” seats, 251 miles of EPA-rated range and a 30 minute 10-80% charge time on a 100 kW DCFC. 0-60 mph performance and highway acceleration is adequate, ranging from a 6.0-second sprint in the EQB 350 models and 7-8 seconds from the 250+ and 300 models.
It’s still a tough sell

Even with the discounts, there’s no escaping the fact that EVs from brands like Chevy, Ford, Hyundai, and Kia have objectively eclipsed the EQB in terms of range, performance, and charging speeds.
That said, the three-pointed star still means something to a lot of buyers. If they can look beyond the specs and take the EQB for a test drive, they might find that the signature Mercedes-Benz feel indeed lives in this well-rounded electric SUV, and that will probably be able to handle everything they throw at it. Plus, with the $7,500 Federal EV Tax Credit set to expire on September 30th, the current deals on this electric SUV might be as good as it gets!

A condominium complex in Northern California recently installed EV chargers into every single one of its 143 parking spots, future-proofing the whole complex for a fully-electrified future, and it managed to do it with zero cost out of pocket. Here’s how.
Now, right off the bat, we have to come clean: the operative phrase, there, is “out of pocket.” While this installation is still very low-cost, it was only made zero-cost for the complex thanks to a utility incentive from Peninsula Clean Energy (PCE), a local clean energy utility in San Mateo County.
However, that incentive covered $2,000 per spot, and that’s still a really low cost for installing chargers into every single parking spot in a complex nonetheless.
The condo complex is Bayview Condominiums in Millibrae, CA, just South of San Francisco. The region is a hotspot for electric vehicle adoption, so there’s no surprise that we’re seeing some big moves in electrification in the area.

The installation uses GoPowerEV chargers, a $1,395 low-power “Level 1” charger that can charge two parking spots at just under 2kW each. That’s rather slow compared to the dedicated chargers you’re probably used to, but it’s enough for the vast majority of driver’s needs – with an overnight charge, you can get around 50 miles worth of range on most of today’s EVs.
But if you do need more than that, there’s an option. Each of GoPowerEV’s chargers has 3 plugs: two 120V, 20A NEMA 5-20 outlets, and one 240V, 20A NEMA 6-20 outlet in the center. The chargers are meant to sit between two parking spots, with drivers using the outer low-powered outlets most of the time.
But if one driver needs a quicker charge on any given night, they can take the middle outlet and request more power for a few extra cents per kWh via GoPowerEV’s app (though, still, only 3.3-3.9kW, and only if your neighbor doesn’t need much of a charge).
This isn’t the only provider or the only solution for an apartment complex. Some complexes install a smaller number of higher-powered, shared chargers at a higher cost, and some have chosen to install a more basic, low-powered outlet for every single spot, meaning nobody has to fight for chargers – and that’s the solution Bayview Condominiums went with.
Low powered charging is a good solution for most
The plus side of this lower power charging is that it can be done for low cost. As mentioned above, this project actually cost the condo complex nothing to install. PCE told us that this was an exceptional case, an easy project with no need to dig trenches or run conduit. It also helps with site design for free, and offers the aforementioned $2k per charger incentive (it also offers incentives for higher-powered charging, but requires cost charing on those projects). Which makes it a bit of a no-brainer for any apartment complex in a similar situation.
Low power charging has become a more popular solution lately for large projects like these lately, as the economics of how cheaply it can be done has really come into focus (and as building codes have changed to accommodate the idea, as happened recently in CA). Each parking spot costs tens of thousands of dollars to build anyway (and even moreso if they’re underground, as is the case at Bayview condos), so a ~$2,000 cost to add EV charging to the spot feels like a drop in the bucket, especially in an EV-heavy area.

Low powered charging is also the favored solution of Forth’s Charge at Home program, because of the low cost and the fact that it covers needs for the vast majority of drivers. Exceptions exist, but it’s always possible for people to backfill a little extra charging with a public charger, work charger, or fast DC charging if a level 1 outlet at home isn’t enough.
Compare, for instance, the cost and magnitude of installing a single 350kW DC fast charger. Yes, this can charge a car in as fast as ~16 minutes or so, but 350kW is a lot of power, creates big spikes in demand, and will usually have a cost in the high five figures to low six figures per charging stall.
Meanwhile, Bayview Condominiums’ entire system has a total power of somewhere on the order of 300kW, and cost about a buck a watt to install (<$2k x 143 units). So, for a similar price as about two fast DC chargers, and with similar overall power delivery levels, the complex was able to electrify every single parking spot. That means nobody has to worry about shuffling around and fighting over the one central charger, everyone can just park in their assigned spots and be full in the morning, the ideal no-stress EV ownership experience.
More apartment charging is better for everyone
But a project like this is not just for areas that already have a lot of EVs, because it can help to enable more EVs. Apartment-dwellers don’t have the easiest time charging, and the trouble of having to search for an apartment that has a charger, or having to go charge publicly at higher cost at often-busy fast chargers takes a lot of the fun out of EV ownership.

So having a charger already set up in the parking lot means your residents will have a much easier time choosing an EV the next time they look into buying a car. And that’s great for everyone – fewer fumes in your parking structure, better air quality in your local community, and another strike in the fight against climate change.
And EV charging is becoming one of the more in-demand features for apartment buildings, with few buildings serving this need. A building can make itself more attractive by adding something like this, for relatively little cost overall.
Electrek’s Take
These options are more for building managers than renters, but this is just another step towards helping to make charging easier for apartment-dwellers. If you’re looking for more resources for apartment EV charging, either as a owner or a renter, find more on that here.
I’ve long said that the only real problem with EVs is charging for people who don’t have access to their own garage. Whether this be apartment-dwellers, street-parkers or the like, the electric car charging experience is often less-than-ideal outside of single family homes, at least in North America.
There are workarounds available, like charging at work, or using Superchargers in “third places” where you often spend time, but these still aren’t optimal. The best bet is just to charge your car wherever it spends most of its time, which is your home. When you do that, EVs outshine everything in convenience.
Hopefully the more competition we see in this space, and the more big projects like these get off the ground successfully and at low cost, the more we can finally move towards solving the problem of apartment charging once and for all.
And, frankly, we also need legislation/building codes to hop in and require this sort of thing, so it becomes the rule rather than the exception and apartment dwellers can feel secure that they’ll be able to find a place to charge. And the lower install costs get, the more realistic a legislative requirement would be.

The Austrian Torrent and Avalanche Control Centre has deployed a Liebherr-developed battery energy storage system to power the cranes, offices, and equipment used in the construction of this year’s consolidation barrier – a critical piece of infrastructure designed to keep Austrians safe from avalanches and landslides this winter.
Here’s how it’s going.
“We could have used a diesel generator to power the construction site as we always have before,” explains Nikolaus Wieser, graduate-level engineer and site manager at the Austrian Torrent and Avalanche Control Centre. “However, we also strive to reduce emissions, so we are delighted to be using this innovative Liebherr solution.”
The battery packs in the mobile, battery-based LPO 100 battery energy storage system (BESS) deployed by Avalanche Contol Centre covers the energy needs of both the Liebherr 34 K fast-erecting crane working on the site, among other tools.
With a capacity of 94 kWh, the energy storage system buffers the fixed power connection on site. In addition to powering the crane, it supplies other equipment, such as container units, battery-powered devices, circular saws and a water pump. During the day, the storage system is used to cover the crane’s energy peaks of up to 100 kVA. Only the energy needed is consumed.
Interestingly, the site does have access to grid energy – but it’s insufficient for the peak energy needs of the crane while it’s in operation. So, when the crane isn’t in use, the batteries in the LPO 100 “trickle charge” with grid and solar, then dump the energy quickly, as needed, eliminating the need for a conventional diesel or has genset.
“The installation went well, and the storage system has been up and running ever since,” added Wieser. “That’s how it should be.”
Electrek’s Take
It’s an odd truth in the construction space, but just because you’re working for the utility doesn’t mean you’ll have adequate power (or any power, for that matter) on the job site. That’s why solutions like this one from Liebherr are critical in the long run game of decarbonizing off-highway vehicles and construction projects.
The engineers Austrian Torrent and Avalanche Control Centre has turned this BESS into something like the Orange Juicer, and by cleverly understanding their own power needs and the fact that energy is the ability to do work, they’re able to get that critical work done in quiet, serene, emission-free comfort and go home without having their brains and ears rattled by the constant thrum of diesel engines.
