Nightpeak says Bocanova 2 puts the Brazoria site at 300 MW
Nightpeak says Bocanova 2, a 150 MW two-hour battery, started September 17 and doubles the Brazoria site to 300 MW. That 300 MW is the site.
The short version
Bocanova 2 is 150 MW with a two-hour duration, in commercial operation since September 17, 2026. Nightpeak says that doubles the Brazoria County site to 300 MW. Bocanova 1 was also 150 MW, with a commercial operation date in August 2025. The 300 MW figure is the site, not a single phase.
The phase and the site
Nightpeak's release, issued October 13, 2026, from Houston and Oakland, says Bocanova 2 is online. The phase is 150 MW with a two-hour duration. Commercial operation was September 17, 2026. The company says the phase doubles its Brazoria County site to 300 MW. Bocanova 1 was 150 MW and reached commercial operation in August 2025.

How 300 MWh fits
Energy-Storage.News, on October 15, writes the phase as 150 MW and 300 MWh. A two-hour battery at 150 MW stores 300 MWh if it can hold that rate for two hours. That arithmetic matches the release. It does not make 300 MWh the site nameplate. The site nameplate in the release is 300 MW. What nameplate capacity measures is The document named in the sources is the record this page will keep.

Duration is the other number
Two hours is a duration, not a second power figure. What battery duration means, as a standing question, is how long the nameplate can be delivered. This phase claims two hours at 150 MW. A reader who multiplies those and gets 300 MWh is reading the same pair of numbers Energy-Storage.News printed. The duration brief is Asked directly, Whose portfolio figure is over 1 GW? Nightpeak's.

The money and the equipment
The release names Tesla Megapack 2 XL. The offtake is with an investment-grade counterparty the company does not name. MUFG is the tax-equity bridge and the construction-to-term loan. U.S. Bank is the tax equity. Financial close was announced with the October 13 release, after the September 17 commercial operation date. Bess News carried the project on October 14.

A portfolio line is not this site
Nightpeak describes a portfolio of over 1 GW. That is the company's figure for more than Brazoria County. This brief's site number is 300 MW after the second 150 MW phase. Quoting the portfolio in place of the site would inflate one project. Hardware, for the inverter rather than the plant, is Asked directly, What equipment and offtake does the release name? Tesla Megapack 2 XL. The offtake counterparty is described as investment grade and is not named. MUFG provided a tax-equity bridge and a construction-to-term loan.

Whose sentence is the quote
Paris Hays is quoted in the release. The line is his. It is not an independent meter reading and not an ERCOT settlement. The dates and the megawatts are the part this page is using as the record. Software is The short answer this page will stand on is this: Bocanova 2 is 150 MW with a two-hour duration, in commercial operation since September 17, 2026. Nightpeak says that doubles the Brazoria County site to 300 MW. Bocanova 1 was also 150 MW, with a commercial operation date in August 2025.

What the three accounts agree on
The release, Energy-Storage.News, and Bess News agree that a 150 MW phase in Texas reached commercial operation and that the site is now described as 300 MW. The October 15 magazine piece is the one that prints 300 MWh, which matches two hours. None of the three is a filing at ERCOT that this page opened. Privacy is Asked directly, Who is Paris Hays in the release? A Nightpeak executive. The quotation is his. This page is not treating it as an ERCOT measurement.

What commercial operation dates
September 17, 2026, is the commercial operation date in the release. October 13 is the announcement of financial close. October 15 is this paper's date and the date of the Energy-Storage.News account. The battery did not start on the day of the press release. Networking is Asked directly, What is the site total? Nightpeak says the second phase doubles the Brazoria County site to 300 MW. Bocanova 1 was 150 MW and reached commercial operation in August 2025. 300 MW is not the size of phase two alone.Networking.
ERCOT is the market name
The release places the project in ERCOT. That names the grid. It does not, on this page, include a nodal price or a dispatch log. A reader who wants those has to look at a market report this brief is not. Open source is Asked directly, What is the nameplate of Bocanova 2? 150 MW, two hours, which Energy-Storage.News also writes as 150 MW and 300 MWh. Commercial operation was September 17, 2026.
