Overview

On October 21, 2026, Vantage, a leading global provider of digital infrastructure, and Heron Power Electronics, a manufacturer of next-generation power electronics and a participant in NVIDIA's 800-volt direct current (800 VDC) MGX ecosystem, announced a strategic, gigawatt-scale manufacturing capacity agreement. Under the agreement, Vantage has secured over 1 GW of manufacturing capacity of Heron Link, Heron's solid-state transformer (SST), to deploy in its hyperscale data center campuses. The collaboration is designed to give artificial intelligence (AI) and cloud customers a faster, more efficient and scalable way to deploy the high-density infrastructure required for next-generation computing. This deal marks one of the largest commercial commitments yet to 800 VDC distribution for AI factories.

Technical Architecture of Heron Link

Heron Link is a solid-state transformer (SST) that converts medium-voltage grid power directly to 800 VDC with integrated energy storage. By reducing conversion stages, it simplifies the path from grid to rack. The system targets more than 98.5% efficiency from medium voltage to 800 VDC. Traditional systems rely on multiple stages of conversion, energy storage, and distribution between grid and rack. As rack densities increase, these systems require more equipment, conductors, floor space, installation labor, and commissioning time. Heron Link integrates power conversion and energy storage to address these challenges.

Contrast with Conventional Data Center Power

Conventional data centers typically use a 480-volt alternating current (480 VAC) architecture. This involves multiple conversion stages: medium-voltage AC is stepped down to low-voltage AC, then converted to DC for IT equipment, with separate energy storage. Each stage introduces losses and requires additional equipment, floor space, and labor. As AI rack densities approach megawatt-class power requirements, the limitations of this approach become more pronounced. The 800 VDC architecture reduces conversion stages and simplifies electrical design, potentially lowering infrastructure requirements and improving efficiency.

Strategic Benefits for AI Infrastructure

The agreement highlights five key benefits of the 800 VDC architecture:

  • Faster time to capacity: Fewer equipment dependencies and installation steps shorten the electrical critical path.
  • Greater energy efficiency: Fewer power-conversion stages reduce losses. Heron Link targets more than 98.5% efficiency from medium voltage to 800 VDC.
  • Support for higher-density computing: 800 VDC supports rapidly increasing AI power requirements, including megawatt-class racks.
  • Lower infrastructure requirements: Simplified design reduces equipment, floor space, materials, and labor compared with 480 VAC.
  • Enhanced energy flexibility: Integrated storage buffers dynamic AI loads, enabling data centers to be more flexible grid partners.

Curtis Aubry, vice president, global product strategy at Vantage, said, "Our customers need a faster and more efficient way to deploy increasingly power-dense and flexible AI infrastructure. By simplifying the electrical architecture and integrating power conversion, energy storage and compute more effectively, we can help reduce deployment complexity, improve efficiency and accelerate our customers' speed to capacity."

Market Context: The Shift to 800 VDC

The announcement comes as AI rack densities approach megawatt-class power requirements and the grid needs additional flexible and interactive loads. Customers face growing constraints related to power availability, electrical equipment, deployment timelines, and cost. The 800 VDC architecture is positioned as a solution. Heron Power's participation in NVIDIA's 800 VDC MGX ecosystem signals industry momentum. Drew Baglino, founder and CEO of Heron Power, said, "By partnering with Vantage to deploy more than a gigawatt of Heron Links in data centers, we will move 800 VDC from a reference architecture concept to a repeatable, deployed platform, delivering power from grid to rack in an integrated system." This agreement is a significant commercial validation.

Implications for Vantage's Hyperscale Campuses

Vantage operates across North America, EMEA, and Asia Pacific, serving AI and cloud innovators. Securing over 1 GW of Heron Link capacity allows Vantage to deploy the SST across its hyperscale campuses. The collaboration aims to give customers a faster, more efficient, and scalable way to deploy high-density infrastructure. By integrating power conversion, energy storage, and compute, Vantage intends to reduce deployment complexity, improve efficiency, and accelerate speed to capacity. The agreement helps Vantage deliver capacity at speed and scale, aligning with its commitment to operational excellence.

Future Outlook

The gigawatt-scale agreement signals a potential shift toward 800 VDC distribution. As AI demands grow, efficient, scalable power architectures become critical. Heron Link's direct medium-voltage to 800 VDC conversion with integrated storage could set a new standard. Challenges like standardization, workforce training, and supply chain scaling remain, but the >1 GW commitment provides a foundation. The partnership moves 800 VDC from concept to deployed platform, potentially accelerating AI infrastructure delivery and enabling data centers to operate as flexible grid partners. The industry will watch as Vantage deploys Heron Link, providing real-world performance data.
