Heron Power modernizes the electrical grid with solid-state transformer technology. Its flagship Heron Link is a modular, megawatt-scale power converter that connects directly to medium voltage, replacing traditional transformers and using wide-bandgap semiconductors for high density and fast voltage/frequency regulation. The system integrates software controls to manage power flows across renewables, storage, and data centers, improving grid stability and reducing equipment footprint. Its goal is to accelerate the all-electric future by delivering scalable, robust grid infrastructure with domestic US manufacturing and pilots starting in 2026.

The company will convert a former 286,000-square-foot distribution warehouse into a manufacturing facility. Heron expects to invest more than $100 million in the site, create more than 600 jobs, and begin mass production in late 2027. The factory is designed to produce up to 10,000 Heron Links per year, representing more than 40 GW of annual capacity. The 5 MW systems are intended for large-scale energy and data center projects. Site preparation is set to begin immediately. The project is supported in part by a $26.4 million California Competes tax credit. Heron Power CEO and founder Drew Baglino said the facility will allow the company to manufacture its power electronics technology at scale in the United States. The company said Morgan Hill was selected following an evaluation of manufacturing locations in several states. The site is close to Heron's engineering headquarters and the Bay Area's engineering and manufacturing workforce.

Heron Power will invest over $100 million to convert a 286,000-square-foot warehouse in Morgan Hill, California, into an advanced manufacturing facility. The factory will produce up to 10,000 Heron Links annually — 5-megawatt power conversion systems for large-scale energy and datacentre projects. The facility is expected to create over 600 jobs in manufacturing, engineering, and operations. Mass production is slated to begin in late 2027. California is supporting the project with a $26.4 million CalCompetes tax credit. Heron Link consolidates multiple pieces of grid equipment into a compact, software-controlled unit designed for higher efficiency and faster deployment. The company aims to address growing demand from AI datacentres and electric vehicles whilst reducing reliance on imported grid components.
Heron Power, LG Energy team up on grid storage. Heron Power and LG Energy Solution Vertech integrate solid-state transformer tech with U.S.-made battery storage for utility-scale projects. June 3, 2026 Heron Power and LG Energy Solution Vertech have announced a design and engineering collaboration to integrate Heron's solid-state transformer-based Heron Link platform with LG Energy Solution Vertech's U.S.-manufactured battery energy storage systems into a validated DC-to-AC platform targeting utility-scale storage and high-load-growth applications including data centers and manufacturing facilities. Heron Link replaces conventional inverter-plus-transformer power conversion skids with a modular solid-state transformer architecture. The integrated system reduces DC block project footprint by 30%, improves energy density to 385 MWh per acre, and delivers 2.4% higher round-trip efficiency. Combined with lower EPC costs from streamlined deployment, project economics improve by up to 6% NPV. "By engineering a holistic solution together, we are unlocking higher power density, greater efficiency, and faster deployment for developers building the grid of the future," said Drew Baglino, CEO of Heron Power. "Our clients can choose to elevate the efficiency of their projects while leveraging advanced, American-made solutions," said Jaehong Park, CEO and president of LG Energy Solution Vertech. The companies are targeting a pilot deployment later this year, with broader commercial availability to follow.

Heron Power partners with LG. Companies combine US-made battery storage and solid-state transformer technology for utility-scale energy projects by Transformer Magazine June 3, 2026 USA, California, Scotts Valley: Heron Power and LG Energy Solution Vertech have entered a design and engineering collaboration to create an integrated energy storage solution for the growing US electricity market. The partnership brings together Heron Power's solid-state transformer-based Heron Link system and LG Energy Solution Vertech's US-manufactured battery energy storage technology. The combined platform is designed for utility-scale storage projects and energy-intensive sectors such as data centres and manufacturing. With electricity demand rising across the United States due to AI infrastructure, industrial expansion and increasing electrification, the companies aim to provide a domestically produced solution that can be deployed quickly and efficiently. Heron Link is designed as an alternative to conventional inverter-and-transformer systems. The modular solid-state transformer architecture offers higher power density, improved efficiency and greater project availability while reducing the space required for installation. According to the companies, the integrated system can reduce the footprint of DC block projects by 30 %, increasing energy density to 385 MWh per acre. The solution is also expected to lower EPC costs, improve availability and deliver 2.4 % higher round-trip efficiency. Together, these advantages could improve project economics by up to 6 % in net present value. The companies said the collaboration reflects a shared commitment to strengthening US energy manufacturing and supporting the next generation of grid infrastructure. A pilot project is planned for later this year to test the integrated system in real-world conditions, with broader commercial availability expected afterwards.
