The rise of grid power electronics with Drew Baglino

Power electronics serve as the critical foundation of the modern electrical grid, enabling dynamic control over voltage and current. While traditional grid infrastructure relies on slow, bulky mechanical switches and passive oil-filled transformers—many dating back to the 1970s—advancements in wide-bandgap semiconductors like silicon carbide now allow for high-frequency, solid-state alternatives. Drew Baglino, founder and CEO of Heron Power, explains that these solid-state transformers (SSTs) offer a step-function improvement in reliability and power density compared to legacy equipment. By replacing passive components with intelligent, software-controlled power electronics, utilities and data center operators can significantly reduce their physical footprint, simplify maintenance, and increase overall grid utilization. This transition to solid-state technology addresses the current transformer supply chain crisis while providing the necessary control to manage the increasing complexity of a decarbonized, electrified energy system.
