Alderbuck Energy

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.

Core offering

Alderbuck Energy manufactures and sells the Nexus Power Unit (NPU), a medium-voltage solid-state transformer platform built on wide-bandgap semiconductors (silicon carbide and gallium nitride) that converts AC grid power to 800VDC for AI data centers, EV charging hubs, and renewable generation sites. The NPU consolidates the functionality of transformers, capacitors, power filters, sensors, inverters, and computing into a single modular system. Paired with the hardware is PowerVectorAI, a software platform providing real-time energy monitoring, predictive maintenance, fault prevention, and AI-driven bidirectional flow coordination, licensed on a recurring basis.

Product overview

Alderbuck Energy offers a platform-plus-modules product architecture centered on two core offerings: the Nexus Power Unit (NPU) solid-state transformer platform and the PowerVectorAI energy management software. The Nexus Power Unit is a modular, solid-state power conversion system that serves multiple market verticals (data centers, renewable generation, EV charging) by replacing multiple pieces of traditional grid equipment (transformers, inverters, capacitors, power filters, sensors) in a single compact system. PowerVectorAI is paired with the NPU to provide real-time AI-powered monitoring, control, predictive maintenance, and optimization of energy flows. Additional offerings include the Mega-Charging Ecosystem Architecture for EV charging applications, which builds on the NPU platform with dynamic energy flow management up to 3.6MW output.
