World’s Longest-Operating Solar Thermal Facility is Retiring Most of its Capacity

The Solar Energy Generating Systems (SEGS) facility in California’s Mojave Desert retired five of its solar plants (SEGS 3 through 7) in July 2021 and plans to retire a sixth (SEGS 8) in September 2021, based on information submitted to EIA and published in our Preliminary Electric Generator Inventory. After SEGS 8 is retired, only one solar thermal unit at SEGS will remain operating (SEGS 9). SEGS, which began operating in 1984, is the world’s longest-operating solar thermal power facility.

Solar thermal power plants use mirrors to focus sunlight onto a receiver, which absorbs and converts the sunlight into thermal energy (heat). The heat is used to drive a turbine, which produces electricity. The SEGS units are parabolic trough concentrating solar thermal power (CSP) systems, meaning that parabolic (u-shaped) mirrors capture and concentrate sunlight to heat synthetic oil in a central tube, which then boils water to create steam. The steam drives the turbine, generating electricity.

The 356-megawatt (MW) SEGS facility was originally made up of nine solar thermal plants. SEGS 1 and 2 were retired in 2015 and replaced with two solar photovoltaic (PV) farms, Sunray 2 and Sunray 3. SEGS 3 through 7 (each with 36 MW of capacity) came online from 1986 to 1988. SEGS 8 and 9 (each with 88 MW of capacity) came online in 1989 and 1990, respectively.

Solar thermal plants account for a relatively small share of utility-scale U.S. solar electric generating capacity. As of June 2021, the United States had about 52,600 MW of utility-scale solar capacity. Of that total, 3.3% was solar thermal; the remaining 96.7% was utility-scale solar PV.

Although solar capacity in the United States is increasing rapidly, most of the capacity additions in recent years have been solar PV. About 42,000 MW of utility-scale PV capacity was added to the U.S. power grid between 2015 and June 2021; no additional solar thermal capacity has been added since the Crescent Dunes plant came online in 2015.

Based on data that developers and power plant owners have reported to EIA, one utility-scale solar thermal plant is planned to come online in the next five years in the United States: Arizona’s 200-MW La Paz Solar Tower. According to trade press and announced projects, several CSP projects are planned or are in development in other countries.

This 'supercharger on wheels' brings fast charging to you [update]

Mobile car care company Yoshi Mobility launched a DC fast charging EV mobile unit that it likens to “a supercharger on wheels.”

November 4, 2024 update: Yoshi Mobility will only be charging EVs on the side of the road now – it announced today that it’s selling its fleet fueling operation to EZFill Holdings (Nasdaq: EZFL).

It was originally founded as a direct-to-consumer, mobile fueling business in 2016, but now it’s going to focus on mobile EV charging, virtual vehicle inspections for partners like Uber and Turo, and onsite preventative maintenance.

Bryan Frist, Yoshi Mobility’s CEO & cofounder, said, “By spinning off our fuel business and focusing all of our energy on solving hair-on-fire problems that fleet owners face, we are meeting the changing needs of enterprise customers while making the future of transportation safer, cleaner, and more sustainable.”

May 22, 2024: Yoshi Mobility saw that its existing customers needed mobile EV charging in places where infrastructure has yet to be installed, so the Nashville-based company decided to bring the mountain to Moses.

“We recognized a demand among our customers for convenient daily charging, reliable private charging networks, and proper charging infrastructure to support their fleet vehicles as they transition to electric,” said Dan Hunter, Yoshi Mobility’s chief EV officer and cofounder.

The company says its 240 kW mobile DC fast charger, which can turn “any EV” into a mobile charging unit, is the first fully electric mobile charger available. It can provide multiple charges in a single trip but doesn’t detail how they charge the DC fast charger or who manufactured it. (I asked for more details, and they replied that they won’t disclose client names or the manufacturer of its DC fast charger yet.)

Yoshi is launching its mobile charger on two GM BrightDrop Zevo 600s and will introduce additional vehicles throughout 2024. It aims for full commercialization by Q1 2025. (I wonder if the Zevo 600 ever charges itself? Yes, I asked that too.)

Yoshi Mobility says it’s already deployed its EV charging solutions to service “major OEMs, autonomous vehicle companies, and rideshare operators” across the US. Its initial customers are made up of large EV operators managing “hundreds” of light-duty vehicles requiring up to 1 megawatt of energy per day that don’t yet have grid-connected EV chargers. I’ve asked Yoshi for details of who it’s working with, and will update if they share that info.

The company says pricing is based on location and enterprise charging needs. Once under contract for service, the service will be deployed to US-based customers within 10 days.

To date, Yoshi Mobility has raised more than $60 million, with investments from GM Ventures, Bridgestone, ExxonMobil, and Y-Combinator in Silicon Valley.

Marqeta shares plunge more than 30% on big forecast miss

Marqeta shares plunge more than 30% on big forecast miss

Marqeta celebrates its initial public offering at the Nasdaq on June 9, 2021.

Marqeta shares tumbled more than 30% in extended trading on Monday after the company issued weaker-than-expected guidance for the fourth quarter.

Here’s how the company did compared with Wall Street estimates, based on a survey of analysts by LSEG:

Loss per share: 6 cents adjusted vs. a loss of 5 cents expected
Revenue: $128 million vs. $128.1 million expected

While third-quarter results showed a slight disappointment on the top and bottom lines, Marqeta’s forecast for the current period was more concerning.

The payment processing firm said revenue in the fourth quarter will increase 10% to 12% from a year earlier. Analysts were looking for growth of more than 17%, according to LSEG.

Marqeta, which primarily functions as a card-issuing platform, attributed the guidance miss to “heightened scrutiny of the banking environment and specific customer program changes.” The company has been struggling for a while, and its stock is now down more than 80% from its peak in 2021, the year it went public. The stock was down 15% for the year prior to the report.

Total processing volume of $74 billion was up more than 30% from a year earlier. Net revenue and gross profit were up 18% and 24%, respectively.

Marqeta’s digital commerce business sells payment technology designed to detect potential fraud and ensure that money is properly routed. It also issues customized physical cards that look like a credit or debit card that can be used for point-of-sale purchases.

The company has been trying to break into the buy now, pay later business with a recently launched product called Marqeta Flex. The service brings BNPL from lenders such as Affirm or Klarna to any credit card wherever Mastercard and Visa are accepted.

“It’s an orchestration layer, but it’s tied to issuing and processing and disputes and chargebacks,” CEO Simon Khalaf told CNBC at Money2020 in Las Vegas last week. “So it is not actually a Wild West in BNPL. It is actually very well established. And there is a reason why a lot of people are jumping to it.”
