Heron Power has secured $140 million in funding to establish a 40-gigawatt, automated U.S. manufacturing facility for its solid-state transformer solution, Heron Link. This technology is designed for critical energy and artificial intelligence data center projects.
Founded in 2024 by former Tesla executive Drew Baglino, Heron Power is developing power electronics-based systems to replace conventional transformers. The goal is to address grid interconnection challenges for renewable energy, battery storage, and large data center deployments. Heron's modular, software-integrated hardware can be manufactured at scale and deployed closer to energy sources and demand centers.
Heron Link uses high-frequency power electronics for voltage conversion and regulation, enabling bidirectional power flow and supporting distributed energy resources. The accompanying software platform manages interconnection, voltage transformation, and power conditioning, integrating with grid control systems.
"Too much of today’s electrical infrastructure is passive, clunky equipment designed decades ago," stated CEO Drew Baglino. "At Heron we are manifesting an alternative future, where modern power electronics enable projects to come online faster, the grid to operate more reliably, and scale affordably."
The company targets utility-scale solar, battery storage, and hyperscale data centers facing long interconnection timelines due to transformer shortages. By using a modular footprint, the technology fits into existing substations, supporting grid expansion and electrification.
The Series B funding round was co-led by Andreessen Horowitz’s American Dynamism Fund and Breakthrough Energy Ventures, with participation from Capricorn Investment Group, Energy Impact Partners, Valor Atreides AI Fund, and Gigascale Capital.
"Heron Power isn’t just making a product that’s essential to bring new electricity generation online and support today’s data center buildout," said Erin Price-Wright of Andreessen Horowitz. "They are building the technology that will catapult our aging electric grid into the software-defined, AI-native twenty-first century. And they are manufacturing it at scale here in America."
This latest funding brings Heron's total raised to approximately $178 million.
