Heron Power
Heron Power is a Scotts Valley, California company building solid-state transformers - power electronics purpose-built for the modern electrical grid. Founded in 2025 by former Tesla powertrain and energy chief Drew Baglino, its flagship Heron Link converts medium-voltage electricity to usable low-voltage power in a modular, software-integrated package, replacing the century-old iron-core transformer. The company targets utility-scale solar, grid-scale batteries, and hyperscale AI data centers, and is building a 40-gigawatt US factory to meet a backlog of orders.
VEIR
VEIR is a Woburn, Massachusetts company commercializing high-temperature superconducting power lines that move 5 to 10 times more electricity than conventional cables at the same voltage and footprint. Its key breakthrough is a passive, evaporative liquid-nitrogen cooling system that keeps superconductors cold without heavy machinery. Founded in 2019 out of Breakthrough Energy Ventures research, VEIR targets utilities, renewable developers, and increasingly the power-hungry AI data center market. It closed a $75M Series B in January 2025 led by Munich Re Ventures, with backing from Microsoft's Climate Innovation Fund.
