Houston-based Rhythm Energy Inc. has acquired Inspire Clean Energy for an undisclosed amount. The deal allows Rhythm to immediately scale outside of Texas and into the Northeast, Midwest and mid-Atlantic regions, according to a release from the company.

Inspire offers subscription-based renewable electricity plans to customers in Pennsylvania, New York, New Jersey, Massachusetts, Ohio, Delaware, Illinois, Maryland, and Washington, D.C. By combining forces, Rhythm will now be one of the largest independent green-energy retailers in the country.

“Adding Inspire to the Rhythm family gives us the geographic reach to serve millions of new customers with the highly rated customer experience Texans already enjoy,” PJ Popovic, CEO of Rhythm, said in the release. “Together we become one of the largest independent green-energy retailers in the country and can roll out innovations like our PowerShift Time-of-Use plan and device-enabled demand-response programs that put customers fully in control of their energy costs.”

Rhythm was founded by Popovic in 2020 and offers 100 percent renewable energy plans using solar power, wind power and other renewable power sources.

In addition to scaling geographically, the acquisition will "(marry) Rhythm's data-driven technology with Inspire's successful subscription model." Rhythm also plans to upgrade its digital tools and provide more advanced services to help lower clean energy costs, according to the release.

Popovic spoke with EnergyCapital in 2023 about where he thinks renewables fit into Texas’s energy consumption. Read more here.

Houston-based Calpine Corp. to be acquired in clean energy megadeal

big deal

Baltimore-based nuclear power company Constellation Energy Corp. and Houston-based Calpine Corp. have entered into an agreement where Constellation will acquire Calpine in a cash and stock transaction with an overall net purchase price of $26.6 billion.

The companies say the agreement has the potential to create America’s “largest clean energy provider,” with what is reported to be the largest fleet of U.S. power stations servicing about 2.5 million customers.

“This is an incredible opportunity to bring together top tier generation fleets, leading retail customer businesses and the best people in our industry to help drive a stronger American economy for a cleaner, healthier and more sustainable future,” Andrew Novotny, president and CEO of Calpine, said in a news release.

Calpine is the largest U.S. producer of energy from low-emission natural gas generation and oversees the largest geothermal generation operation in the U.S. Last year it announced plans to build the Baytown Carbon Capture and Storage Project (Baytown CCS Project), a first-of-its-kind carbon capture demonstration facility, as part of a cost-sharing agreement with the U.S. Department of Energy.

Constellation is considered the top clean energy producer in the U.S., which provides 10 percent of the country’s emissions-free energy. The deal will add to Constellation’s already diverse portfolio of zero- and low-emission sources, including nuclear, natural gas, geothermal, hydro, wind, solar, cogeneration and battery storage.

“Both companies have been at the forefront of America’s transition to cleaner, more reliable and secure energy, and those shared values will guide us as we pursue investments in new and existing clean technologies to meet rising demand,” Joe Dominguez, president and CEO of Constellation, said the release. “What makes this combination even more special is it brings together two world-class teams, with the most talented women and men in the industry, who share a noble passion for safety, sustainability, operational excellence and helping America’s families, businesses and communities thrive and grow. We look forward to welcoming the Calpine team upon closing of this transaction.”

Constellation also announced that it will invest in adding more zero-emission energy to the grid to create “the most reliable generation portfolio in the U.S.” It plans to explore new advanced nuclear projects, invest in renewables and increase the output of existing nuclear plants.

“Together, we will be better positioned to bring accelerated investment in everything from zero-emission nuclear energy to battery storage that will power our economy in a way that puts people and our environment first,” Novotny said in a news release. “It’s a win for every American family and business in our newly combined footprint that wants clean and reliable energy. ECP’s commitment to these goals over the last seven years was critical to the progress we have made as a company and to laying a foundation for future 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.
