Report: Texas shines as top state for new solar, battery capacity

On a state-by-state basis, Texas will account for the biggest share of new utility-scale solar capacity and new battery storage capacity in 2024, a new federal report predicts.

The report, published by the U.S. Energy Information Administration (EIA), says Texas will make up 35 percent of new utility-scale solar capacity in the U.S. this year, followed by California (10 percent) and Florida (six percent).

In 2024, EIA expects a record-setting addition of 36.4 gigawatts of utility-scale solar capacity across the U.S., nearly double last year’s record-setting addition of 18.4 gigawatts. One gigawatt of electric-generating capacity can power an average of 750,000 homes.

“As the effects of supply chain challenges and trade restrictions ease, solar continues to outpace capacity additions from other generating resources,” the report states.

Meanwhile, a new report from the Environment Texas Research & Policy Center and the Frontier Group found that Texas ranks third in the U.S. for residential solar power generation. Residential solar power generation in Texas grew 646 percent from 2017 through 2022, according to the report.

A February 2023 poll conducted by the University of Houston indicated that nearly two-thirds (64 percent) of Texas homeowners are somewhat or very interested in buying a solar energy system.

“Texas is already soaking up the benefits of rooftop solar,” says Luke Metzger, executive director of the Environment Texas center. “With federal tax credits in place to boost solar adoption in Texas, now is the time to lean in. Every sunny roof without solar panels is a missed opportunity.”

In addition to a spike in utility-scale solar, the EIA report forecasts Texas will lead the way this year in the addition of battery storage capacity, with the expected addition of 6.4 gigawatts. In second place is California, with an expected 5.2 gigawatts of new battery storage capacity. The two states will make up 82 percent of new U.S. battery storage capacity in 2024, says the report.

The federal agency predicts 14.3 gigawatts of U.S. battery storage capacity will be tacked on this year to the existing 15.5 gigawatts.

Overall, EIA anticipates solar will make up 58 percent of all new utility-scale electric-generating capacity this year in the U.S., followed by battery storage at 23 percent.

Shortly after announcing a $133.65 Series A funding round, Conroe-based Hertha Metals broke ground Oct. 8 on a $100 million factory that will produce steel-grade and magnet-grade high-purity iron.

Hertha’s Chalyx plant, located in Conroe, will manufacture a total of about 10,000 metric tons per year of magnet-grade and steel-grade high-purity iron. The factory will use Hertha’s single-step process to generate high-purity iron for rare-earth-magnet and steel manufacturers in the U.S.

Hertha says Chalyx will be the first U.S. commercial plant for production of magnet-grade high-purity iron.

Chalyx is being built next to Hertha’s headquarters and its Pi100 pilot plant, which will remain in operation. Chalyx and Pi100 will form the first modern-day iron and steel “innovation complex” in the U.S., the company says.

“I founded Hertha Metals because I believed we could significantly improve how the world makes iron and steel from ore, and that an industry so fundamental to our future still had enormous room for invention,” Laureen Meroueh, founder and CEO of Hertha, said in a press release.

The 4-year-old startup says the Chalyx complex will lay the foundation for its first 500,000-ton-per-year steel mill.

Chalyx’s first priority is making high-purity iron for U.S. manufacturers of rare-earth magnets, Hertha says. These magnets are critical components for electric vehicles, data centers, wind turbines and defense systems.

China produces an estimated 94 percent of high-purity iron for rare-earth magnets, according to Hertha.

Aside from iron for rare-earth magnets, Chalyx will make iron and steel for pilot projects in the steel industry.

The plant is expected to come online in late 2027, with production of magnet-grade high-purity iron starting in early 2028.

Today, Hertha employs 32 people, the company says. Once it’s fully operating, the Chalyx plant will employ about 50 people.

Just ahead of the groundbreaking, Hertha announced the $133.65 million Series A round, co-led by Khosla Ventures and Doerr Capital. The round included a $65 million equity investment from the Pentagon.

“Iron and steel have shaped human progress for thousands of years. And I believe there is still an enormous amount left to invent,” Meroueh said at the groundbreaking ceremony.
