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-based power provider NRG Energy Inc. has formed a joint venture with two other companies to meet escalating demand for electricity to fuel the rise of data centers and the evolution of generative AI.

NRG’s partners in the joint venture are GE Vernova, a provider of renewable energy equipment and services, and TIC – The Industrial Co., a subsidiary of construction and engineering company Kiewit.

“The growing demand for electricity in part due to GenAI and the buildup of data centers means we need to form new, innovative partnerships to quickly increase America’s dispatchable generation,” Robert Gaudette, head of NRG Business and Wholesale Operations, said in a news release. “Working together, these three industry leaders are committed to executing with speed and excellence to meet our customers’ generation needs.”

Initially, the joint venture will work on four projects supplying 5 gigawatts of power from combined-cycle power plants, which uses a combination of natural gas and steam turbines that produce additional electricity from natural gas waste. Electricity from these projects will be produced for power grids operated by the Electric Reliability Council of Texas (ERCOT) and PJM Interconnection. The projects are scheduled to come online from 2029 through 2032.

The joint venture says the model it’s developing for these four projects is “replicable and scalable,” with the potential for expansion across the U.S.

The company is also developing a new 721-megawatt natural gas combined-cycle unit at its Cedar Bayou plant in Baytown, Texas. Read more here.
