The D.C.-based company announced the successful financial close of its first institutional project financing totaling $233 million, backed by ING Group and KeyBank. The financing will support three battery energy storage system (BESS) projects in Texas.

Lydian is an independent power producer that specializes in the development, construction and operation of utility-scale solar and battery energy storage projects. The company reports that it plans to add 550 megawatts of energy—which can power approximately 412,500 homes—to the Texas grid administered by ERCOT.

“This financing marks an important step forward as we continue executing on our vision to scale transformative battery storage projects that meet the evolving energy needs of the communities we serve,” Emre Ersenkal, CEO at Lydian Energy, said in a news release.

The projects include:

Pintail

  • Located in San Patricio county
  • 200 megawatts
  • Backed by ING

Crane

  • Located in Crane county
  • 200 megawatts
  • Backed by ING

Headcamp

  • Located in Pecos county
  • 150 megawatts
  • Backed by KeyBank

ING served as the lender for Pintail and Crane projects valued at a combined total of approximately $139 million.

KeyBank provided a $94 million financing package for the Headcamp project. KeyBanc Capital Markets also structured the financing package for Headcamp.

The three projects are being developed under Excelsior Energy Capital’s Fund II. Lydian’s current portfolio comprises 20 solar and storage projects, totaling 4.7 gigawatts of capacity.

“Our support of Lydian’s portfolio reflects ING’s focus on identifying strategic funding opportunities that align with the accelerating demand for sustainable power,” Sven Wellock, managing director and head of energy–renewables and power at ING, said in the release. “Battery storage plays a central role in supporting grid resilience, and we’re pleased to back a platform with strong fundamentals and a clear execution path.”

The facilities are expected to be placed in service by Q4 2025. Lydian is also pursuing additional financing for further projects, which are expected to commence construction by the end of 2025.

“These financings represent more than capital – they reflect the strong demand for reliable energy infrastructure in high-growth U.S. markets,” Anne Marie Denman, co-founding partner at Excelsior Energy Capital and chair of the board at Lydian Energy, added in the news release. “We’re proud to stand behind Lydian’s talented team as they deliver on the promise of battery storage with bankable projects, proven partners, and disciplined execution. In the midst of a lot of noise, these financings are a reminder that capital flows where infrastructure is satisfying fundamental needs of our society – in this case, the need for reliable, sustainable, domestic, and affordable energy.”

Chevron CEO touts biofuels as part of its renewable energy efforts

Betting on biofuels

As Chevron Chairman and CEO Mike Wirth surveys the renewable energy landscape, he sees the most potential in biofuels.

At a recent WSJ CEO Council event, Wirth put a particular emphasis on biofuels—the most established form of renewable energy—among the mix of low-carbon energy sources. According to Biofuels International, Chevron operates nine biorefineries around the world.

Biofuels are made from fats and oils, such as canola oil, soybean oil and used cooking oil.

At Chevron’s renewable diesel plant in Geismar, Louisiana, a recent expansion boosted annual production by 278 percent — from 90 million gallons to 340 million gallons. To drive innovation in the low-carbon-fuels sector, Chevron opened a technology center this summer at its renewable energy campus in Ames, Iowa.

Across the board, Chevron has earmarked $8 billion to advance its low-carbon business by 2028.

In addition to biofuels, Chevron’s low-carbon strategy includes hydrogen, although Wirth said hydrogen “is proving to be very difficult” because “you’re fighting the laws of thermodynamics.”

Nonetheless, Chevron is heavily invested in the hydrogen market:

As for geothermal energy, Wirth said it shows “some real promise.” Chevron’s plans for this segment of the renewable energy industry include a 20-megawatt geothermal pilot project in Northern California, according to the California Community Choice Association. The project is part of an initiative that aims to eventually produce 600 megawatts of geothermal energy.

What about solar and wind power?

“We start with things where we have some reason to believe we can create shareholder value, where we’ve got skills and competency, so we didn’t go into wind or solar because we’re not a turbine manufacturer installing wind and solar,” he said in remarks reported by The Wall Street Journal.

In a September interview with The New York Times, Wirth touched on Chevron’s green energy capabilities.

“We are investing in new technologies, like hydrogen, carbon capture and storage, lithium and renewable fuels,” Wirth said. “They are growing fast but off a very small base. We need to do things that meet demand as it exists and then evolve as demand evolves.”

Houston robotics company partners with Marathon Petroleum to scale fleet

robot alliance

Houston- and Boston-based Square Robot Inc. has announced a partnership with downstream and midstream energy giant Marathon Petroleum Corp. (NYSE: MPC).

The partnership comes with an undisclosed amount of funding from Marathon, which Square Robot says will help "shape the design and development" of its submersible robotics platform and scale its fleet for nationwide tank inspections.

“Marathon’s partnership marks a major milestone in our mission to transform industrial tank inspection,” David Lamont, CEO of Square Robot, said in a news release. “They recognize the proven value of our robotic inspections—eliminating confined space entry, reducing the environmental impact, and delivering major cost efficiencies all while keeping tanks on-line and working. We’re excited to work together with such a great company to expand inspection capabilities and accelerate innovation across the industry.”

The company closed a $13 million series B last year. At the time of closing, Square Robot said it would put the funding toward international expansion in Europe and the Middle East.

Square Robot develops autonomous, submersible robots that are used for storage tank inspections and eliminate the need for humans to enter dangerous and toxic environments. Its newest tank inspection robot, known as the SR-3HT, became commercially available and certified to operate at a broader temperature range than previous models in the company's portfolio this fall.

The company was first founded in the Boston area in 2016 and launched its Houston office in 2019.
