Oakland, California-based Nightpeak Energy announced earlier this month that its 150-megawatt battery storage project in Brazoria County, known as Bocanova Power, is now operating to address Houston’s peak capacity needs.

“This battery storage project will enhance grid reliability in the Alvin area while continuing to support integrating renewable energy,” Cary Perrin, president and CEO of the Northern Brazoria County Chamber of Commerce, said in a news release. “I believe we need energy storage now more than ever for its pivotal role in reducing strain on the grid while meeting fast-growing power demand in Texas and Brazoria County."

The project reached commercial operation in August, according to the release. The project utilizes Tesla's Megapack 2 XL battery storage system, and the facility operates under a long-term power purchase agreement with an undisclosed “investment-grade power purchaser.”

“Bocanova Power demonstrates the speed at which Nightpeak Energy is overcoming complex challenges to energize projects that support America's growing need for affordable, reliable, and secure energy,” Paris Hays, co-founder and CEO/CDO of Nightpeak Energy, added in the news release. “Unprecedented AI data center and manufacturing growth has only accelerated the need for these resources.”

Hays added in the release that the company has plans for more energy infrastructure projects in Texas and in the Western U.S.

Nightpeak Energy develops, owns and operates power plants that support the growing capacity needs of a decarbonized grid. It also owns and operates 240 MW of battery storage and natural gas generation facilities.

The company was founded in 2022 and backed by equity funding of up to $200 million from Dallas-based investment firm Energy Spectrum Capital.
