Energy Equation Partners, a London-based investment firm focused on clean energy companies, and New York-based Stonepeak have completed the acquisition of a 65 percent interest in JET Tankstellen Deutschland GmbH, a subsidiary of Houston oil and gas giant Phillips 66.

JET is one of the largest and most popular fuel retailers in Germany and Austria with a rapidly growing EV charging network, according to a news release. It also operates approximately 970 service stations, convenience stores and car washes.

“We are delighted to complete this acquisition and to partner with Stonepeak and Phillips 66 to take JET to the next level,” Javed Ahmed, managing partner of Energy Equation Partners, said in a news release. “This investment reflects EEP’s commitment to investing in established players in the energy sector who have the potential to make a meaningful impact on the energy transition, and we are excited to work alongside the entire JET team, including its dedicated service station operators, to realize this vision.”

The deal values JET at approximately $2.8 billion. Phillips 66 will retain a 35 percent non-operated interest in JET and received about $1.6 billion in pre-tax proceeds.

“Under Phillips 66’s ownership, JET has grown into one of the largest fuel retailers in Germany and Austria," Anthony Borreca, senior managing director and co-head of energy at Stonepeak, added in a news release. "We are excited to join forces with them, as well as Javed and the EEP team, who have long-standing experience investing in and operating retail fuel distribution and logistics globally, to support the next phase of JET’s growth.”

Houston-based NRG announces new CEO and succession plan

new leader

Houston-based NRG Energy Inc. announced Jan. 7 that it has appointed Robert J. Gaudette as president and CEO. Gaudette took over as president effective Jan. 7 and will assume the role of CEO April 30, coinciding with the company's next stockholder meeting.

Gaudette, who previously served as executive vice president and president of NRG Business and Wholesale Operations, will succeed Lawrence Coben in the leadership roles. Coben will remain an advisor to NRG through the end of the year and will also continue to serve as board chair until April 30. Antonio Carrillo, lead independent director at NRG, will take over as board chair.

"Rob has played a central role in strengthening NRG’s position as a leader in our industry through strategic growth, operational excellence, and customer-focused innovation," Coben said in the news release. "He is a strong, decisive leader with extensive knowledge of our business, markets, and customers. The Board and I are confident that Rob is the right person to lead NRG forward and take the NRG rocket ship to new heights. I can’t wait to see what comes next.”

Gaudette has been with NRG since 2001. He has served as EVP of NRG Business and Market Operations since 2022 and president of NRG Business and Market Operations since 2024. In these roles, he led NRG’s power generation and oversaw its portfolio of commercial and industrial products and services as well as its market operations, according to the company.

He has held various executive leadership roles at NRG. He earned his bachelor's degree in chemistry from The College of William and Mary and an MBA at Rice University, where he was a Jones Scholar. He also served four years as an Army officer.

“It is an honor to be appointed NRG’s next CEO at this transformative time for the energy sector and our company,” Gaudette said in the release. “With NRG’s electricity, natural gas and smart home portfolio, we are ideally positioned to meet America’s evolving energy needs. I am grateful to Larry and all my NRG colleagues, both past and present, who built our great company and positioned us for the future. I look forward to leading our incredible team to deliver affordable, resilient power for the customers and communities we serve, while creating substantial value for our shareholders.”

In addition to its traditional power generation and electricity businesses, NRG has been working to develop a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035 in an effort to meet Texas’ surging energy demands.

The company announced partnerships last year with two California-based companies to bolster home battery use and grow its network. NRG has said the VPP could provide energy to 200,000 homes during peak demand.

Japanese company launches solar module manufacturing at Houston-area plant

solar plant

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.
