Energy storage owner-operator Nightpeak Energy has reached financial close and commercial operation on its 150MW/300MWh Bocanova 2 battery storage project in Brazoria County, Southeast Texas.
Announced 13 October, this brings the total capacity of its Bocanova battery energy storage system (BESS) project to 300MW. The project reached commercial operation on 17 September. Nightpeak stated it will add further flexibility to the Electric Reliability Council of Texas (ERCOT) grid at a time when data centres and other large loads are driving rapid growth in electricity demand across the state.
Bocanova 2 is the second phase of Nightpeak’s BESS development near the Houston metropolitan area, following Bocanova 1, a 150MW project that reached commercial operation in August 2025. Like its predecessor, Bocanova 2 uses Tesla’s Megapack 2 XL BESS solution.
The project is operating under a long-term offtake agreement with an unnamed investment-grade counterparty. Financing was arranged through a tax equity bridge loan and construction-to-term loan with MUFG Bank, while US Bank provided traditional tax equity.

Bocanova 1 had previously taken around two years to move from interconnection request to commercial operation, with Paris Hays, Co-founder and CEO/CDO at Nightpeak noting at the time that the company owned and operated 240MW of BESS and natural gas generation. The addition of Bocanova 2 extends that build-out considerably.
Nightpeak was founded in 2022 by four former colleagues from Recurrent Energy, the US-based solar PV development subsidiary of Canadian Solar.
The company has previously received backing of up to US$200 million in equity funding from Texas-based investment firm Energy Spectrum Capital, drawn from its near-US$1 billion Energy Spectrum Partners Fund VIII, alongside a letter of credit facility from a major US lender.
