What Alderbuck Energy does
Alderbuck Energy is a San Diego-based cleantech startup founded in 2024 that develops solid-state transformer (SST) platforms for power conversion and distribution. Its flagship product, the Nexus Power Unit (NPU), uses wide-bandgap semiconductors (silicon carbide and gallium nitride) to convert medium-voltage AC grid power into 800VDC for high-density AI data centers, while also addressing EV charging and renewable generation/storage applications. The system consolidates transformers, capacitors, power filters, sensors, inverters, and computing into a single modular platform, delivering claimed benefits of 20-30% lower project CAPEX, 3-5% higher energy efficiency, 50-70% smaller electrical footprint, and 20-week lead times versus 40+ weeks for conventional transformers.
The company's revenue model combines hardware sales of the NPU platform with recurring software licensing for its AI-powered PowerVectorAI energy management system, plus professional services for applications engineering and deployment. Alderbuck pursues a direct enterprise sales motion targeting hyperscale data center developers, utilities, and EV charging operators, supplemented by participation in industry events (PG&E Innovation Pitch Fest, OCP community) and standards bodies to build technical credibility. Customers and partners include UC San Diego / San Diego Supercomputer Center (CEC-funded pilot), San Diego Gas & Electric, and Pacific Gas and Electric.
Manufacturing takes place at a 31,000-square-foot UL DAP-certified facility in Dearborn, Michigan (expanded January 2026), with corporate headquarters in San Diego. The company has raised approximately $6 million in seed funding from founders and Starshot Capital, with a separate $2 million Reg D private placement underway. The company remains pre-commercial at scale, with product validation occurring primarily through grant-funded pilots rather than recurring commercial revenue.
