A Northern California-born energy storage startup has established its headquarters in The Woodlands.

Plus Power, which develops battery systems designed to store backup power for electric grids, recently signed a lease for nearly 7,000 square feet at Three Hughes Landing in The Woodlands. The company previously was based in coworking space at the Rayford Office Park in Spring.

The company, founded in 2018, shifted its headquarters from San Francisco to the Houston area last year.

“We chose The Woodlands for its beauty, and walkable access to great nearby hotels, restaurants, and healthy groceries,” says Brandon Keefe, CEO of Plus Power. “A Houston base reflects our deep focus on the Texas market, as we are investing nearly $1 billion in several projects here that will be online by the first quarter of 2024, with more in [the works] behind that.”

About 40 employees work from Plus Power’s new office in The Woodlands. Across North America, the company employs about 130 people, including several in Austin. As of July 10, the startup listed nine job openings.

Plus Power develops, owns, and operates utility-scale systems that store energy in huge lithium-ion batteries during low-demand periods. In times of peak demand, power providers can tap into this stored energy.

“Standalone energy storage is rapidly transforming the U.S. energy markets, because it is cheaper than new natural gas plants, faster to build than fossil peakers or transmission, and able to perform diverse energy services,” the company explains in its job postings.

Peakers are backup power plants that run on fossil fuels.

One of Plus Power’s storage facilities is the 100-megawatt Gambit project, which opened two years ago in Angleton. The nearly eight-acre facility supports power supplies for the Electric Reliability Council of Texas (ERCOT), which runs the power grid for 90 percent of Texas.

The company says the Angleton facility has fed backup energy to ERCOT during this year’s and last year’s heatwaves, as well as last December’s winter freeze.

The Gambit facility might ring a bell with some folks in the Houston area. In January 2022, Austin-based automaker Tesla unveiled a backup power storage facility in Angleton. Plus Power bought the project from Tesla in June 2022.

Plus Power’s development pipeline contains 10 gigawatts’ worth of energy storage projects in 28 states and Canada. That includes massive projects on tap for Hawaii and Arizona.

Last November, Plus Power announced it had secured $219 million in debt financing for construction of the 185-megawatt Kapolei project on a roughly eight-acre site in Oahu, Hawaii. The facility will be tied to Hawaiian Electric’s power grid. Mizuho Securities USA and KeyBank led the financing.

This April, Plus Power held a groundbreaking ceremony for the Sierra Estrella project in Tolleson, a Phoenix suburb. The 250-megawatt system will serve Salt River Project (SRP), a utility provider in the Phoenix area. The roughly 11-acre Tolleson facility is set to open next year, as is another Plus Power project for SRP — the 90-megawatt Superstition facility in Gilbert, another Phoenix suburb.

As its development pipeline demonstrates, Plus Power is firmly plugged into the fast-growing energy storage market.

According to the Houston-based energy research and consulting firm Wood Mackenzie and the American Clean Power Association, the U.S. energy storage market installed a record-breaking 4.8 gigawatts of capacity in 2022. This year, that number is projected to approach 75 gigawatts.

In a March 2023 news release, John Hensley, the clean power group’s vice president of research and analytics, says the U.S. market “is on a rapid growth curve and is already a key component of building a resilient grid that supports abundant clean energy.”

Houston has the lowest inflation problem in the U.S., new study finds

Money Talk

Despite the national inflation rate sitting at 3 percent as of September 2025, the impact of inflation on Houston and the surrounding area isn't as severe as the rest of the U.S., a new study has revealed.

Houston-The Woodlands-Sugar Land ranked as the metro with the smallest inflation problem in the U.S. in WalletHub's October 2025 "Changes in Inflation by City" report.

The study tracked inflation changes for 23 major metropolitan statistical areas (MSAs) using Consumer Price Index data from the latest month available and compared to data from two months prior. The analysis also factored in inflation data from last year to analyze both short- and long-term inflation changes.

Compared to two months ago, the inflation rate in Houston fell by 0.1 percent, and local inflation is only 1.10 percent higher than it was a year ago, WalletHub said.

Houston residents may be feeling the sting a lot less than they did in January 2024, when WalletHub said the city had the 7th highest inflation rate in the country. And yet, Houstonians are increasingly concerned with the economy and its effects on inflation, a recent University of Houston survey found.

A separate WalletHub study named Texas the No. 1 most "financially distressed" state in the U.S. for 2025, adding to the severity of Texans' economical woes.

U.S. cities with the worst inflation problems

Denver-Aurora-Lakewood, Colorado topped the list as the city with the No. 1 worst inflation problem as of September. The Denver metro saw a 1 percent uptick in inflation when compared to two months prior, and it's 3.10 percent higher than it was a year ago.

Elsewhere in Texas, WalletHub ranked Dallas-Fort Worth-Arlington as the metro with the 8th lowest inflation problem nationwide. That's a fair shift from a previous report from June 2025 that ranked DFW the No. 1 U.S. metro with the lowest inflation issues.

The top 10 metros where inflation has risen the most as of September 2025 are:

  • No. 1 – Denver-Aurora-Lakewood, Colorado
  • No. 2 – Los Angeles-Long Beach-Anaheim, California
  • No. 3 – Chicago-Naperville-Elgin, Illinois-Indiana-Wisconsin
  • No. 4 – Boston-Cambridge-Newton, Massachusetts-New Hampshire
  • No. 5 –Minneapolis-St. Paul-Bloomington, Minnesota-Wisconsin
  • No. 6 – (tied) Philadelphia-Camden-Wilmington, Pennsylvania-New Jersey-Delaware-Maryland and Washington-Arlington-Alexandria, D.C.-Virginia-Maryland-West Virginia
  • No. 8 – Anchorage, Alaska
  • No. 9 – New York-Newark-Jersey City, New York-New Jersey-Pennsylvania
  • No. 10 – San Diego-Carlsbad, California

Axiom Space taps solar array developer for first space station module

space contract

Houston-based Axiom Space is making progress on developing its commercial space station.

The company awarded Florida-based Redwire Corporation a contract to develop and deliver roll-out solar array (ROSA) wings to power the Axiom Payload Power Thermal Module (AxPPTM), which will be the first module for the new space station.

AxPPTM will initially attach to the International Space Station. AxPPTM will later separate from the ISS and rendezvous with Axiom’s Habitat 1 (AxH1) on orbit. Eventually, an airlock, Habitat 2 (AxH2) and finally the Research and Manufacturing Facility (AxRMF) will be added to the first two Axiom modules.

AxPPTM is anticipated to launch toward the end of 2027. The two-module station (AxPPTM and AxH1) is expected to be operational as a free-flying station by 2028, and the full four-module station around 2030.

The modules will be integrated and assembled at Axiom Space’s Assembly and Integration facility, making them the first human-rated spacecraft built in Houston.

Redwire’s ROSA technology was originally developed for the ISS, according to Space News. It has yielded a 100 percent success rate on on-orbit performance. The technology has also been used on NASA’s Double Asteroid Redirection Test mission, the Maxar-built Power and Propulsion Element for the Artemis Lunar Gateway and Thales Alenia Space’s Space Inspire satellites.

“As a market leader for space power solutions, Redwire is proud to be selected as a strategic supplier to deliver ROSAs for Axiom Space’s first space station module,” Mike Gold, Redwire president of civil and international space, said in a news release. “As NASA and industry take the next steps to build out commercial space stations to maintain U.S. leadership in low-Earth orbit, Redwire continues to be the partner of choice, enabling critical capabilities to ensure on-orbit success.”

Greentown Houston to add new AI lab for energy startups

AI partnership

Greentown Labs has partnered with Shoreless to launch an AI lab within its Houston climatetech incubator.
