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.

Heron Power has announced a collaboration with LG Energy Solution Vertech to integrate Heron's solid-state transformer technology with LG's US-manufactured battery energy storage systems. The partnership combines American-made lithium-ion batteries with medium-voltage power electronics for utility-scale storage and high-demand applications like data centres. The integrated system reduces project footprint by 30%, achieving 385 MWh per acre energy density. It delivers 2.4% higher round-trip efficiency and improved project economics of up to 6% net present value through streamlined deployment and lower engineering costs. The companies plan a pilot deployment later this year, with commercial availability to follow. The collaboration addresses growing US electricity demand driven by AI infrastructure, industrial expansion and electrification, whilst strengthening domestic energy storage supply chains.

Three startups modernising electrical transformers have recently raised significant funding rounds. DG Matrix secured $60 million in Series A, Heron Power raised $140 million in Series B, and Amperesand obtained $80 million in November. These companies are developing solid-state transformers that replace traditional copper-and-iron devices with power electronics using silicon-based semiconductors. Unlike conventional transformers, the new technology offers real-time monitoring, bidirectional power flow, and software updates whilst handling multiple tasks in a single device. Data centres represent the initial target market, where solid-state transformers can replace several pieces of equipment whilst occupying 70% less space. The technology arrives as existing transformers age — over 50% of US distribution transformers exceed 35 years old — and demand surges from data centres and EV chargers.
