Tesla's Megapacks to Deliver Power for a $600 Million Battery Energy Storage System in California
In Poway, California, the Nighthawk Energy Storage Project is taking shape, set to be completed in January 2026. This utility-scale battery energy storage system (BESS) is a collaborative effort between Arevon Energy and Tesla, with a capacity of 300 MW and 1,200 MWh.
Arevon Energy, a company already behind a 200 MW Tesla Megapack-powered BESS in Barrio Logan, near San Diego, is the owner, operator, and developer of the Nighthawk Project. The $600 million investment promises to deliver a state-of-the-art facility that will significantly stabilise California’s energy grid and reduce the risk of brownouts and blackouts.
The Nighthawk facility is designed to power up to 385,000 homes for up to four hours daily during peak demand, thus preventing potential blackouts or brownouts. The project emphasises advanced safety measures and will use the safest and most advanced battery technology available from Tesla.
The safety of the Nighthawk facility is a top priority, with Kevin Smith, CEO of Arevon Energy, stating that the project's design includes added safety measures and will comprise the safest and most advanced batteries on the market today. The company has also partnered with local fire departments to ensure community safety around the battery facility.
Economically, the Nighthawk Project is expected to create over 130 local jobs during construction and generate more than $30 million in payments to the local government over its lifetime. The City of Poway is set to receive approximately $12 million from the project to support infrastructure, schools, and public services.
Tesla's Megapacks, pre-assembled, containerised battery units designed for utility-scale applications, have proven their safety and reliability through numerous deployments globally. Last year, Tesla built 10,000 units of the Megapack in Lathrop, California, and recently celebrated its 1,000th Megapack produced at its Shanghai Megafactory.
To support growing demand, Tesla recently signed a $4.3 billion deal with LG Energy Solution for U.S.-made LFP batteries, reportedly for use in Megapack and other energy storage products.
The Nighthawk Energy Storage Project is one of Arevon's many successful renewable energy and battery storage projects in California and throughout the United States. With its completion in January 2026, it will undoubtedly contribute to California’s renewable energy integration and decarbonization efforts, providing clean energy storage and dispatchability.
