Nightpeak Doubles Bocanova Storage to 300 MW in ERCOT Market
Houston – – October 13, 2026 -- Nightpeak Energy has closed financing on and brought online its 150 MW, two-hour Bocanova 2 battery storage project in Southeast Texas, doubling the Bocanova site to 300 MW as data centers and other large loads drive electricity demand growth on the ERCOT grid.
Bocanova 2 reached commercial operation on September 17
The project is the second phase of Nightpeak's battery development in Brazoria County, near the Houston metropolitan area. The first 150 MW phase, Bocanova 1, began commercial operation in August 2025. The site is located in what the company describes as one of the country's fastest-growing electricity load centers.
Tesla Megapack 2 XL systems anchor the 150 MW build
Bocanova 2 uses Tesla's Megapack 2 XL battery storage systems. It operates under a long-term offtake agreement with an investment-grade counterparty, which the source does not name.
