Vantage and Heron Power Electronics announced on October 21, 2026, that Vantage has reserved more than 1 gigawatt of manufacturing capacity for Heron Link solid-state transformers. The equipment is intended for future hyperscale AI campuses. This is a production-capacity reservation, not evidence that 1 GW of units has been delivered or energized.

Key Takeaways

• The deal secures more than 1 GW of future manufacturing capacity for Heron Link.
• The planned architecture converts medium-voltage AC power directly to 800 VDC and integrates energy storage.
• Deployment sites, delivery schedules and contract value were not disclosed.

Power conversion from grid to rack

Heron Link targets greater than 98.5% conversion efficiency from medium voltage to an 800-volt DC distribution system, according to the companies. Its integrated storage is intended to buffer the rapid load fluctuations associated with AI computing. Those are product design targets and claims, rather than independently verified efficiency measurements from Vantage campuses.

The shift matters as AI systems approach much higher rack power densities. Conventional designs may require multiple conversion and distribution stages. A consolidated architecture could reduce electrical equipment, cable runs, space and installation work. BitcoinVersus.Tech previously examined 54 V versus 800 V power for AI racks and another solid-state transformer technology effort.

Inside the solid-state transformer

Unlike a conventional line-frequency transformer, solid-state conversion uses power semiconductors and high-frequency switching to regulate electricity. The approach could allow more active control of voltage and power quality, but protection coordination, thermal performance, serviceability and actual operating uptime will determine its commercial value.

Heron is developing a California manufacturing base. Its Morgan Hill factory plan targets mass production in late 2027, with an eventual annual nameplate output exceeding 40 GW. Planned factory capacity should not be confused with shipped products or demonstrated field performance.

What comes next

Vantage has not identified the campuses that will receive these systems, nor has it published equipment delivery dates or pricing. The agreement is a significant procurement signal for 800 VDC, but its technical promise will have to be tested against actual installations, maintenance costs and grid interconnection requirements. Related coverage includes Hitachi’s transformer manufacturing expansion and a separate 1 MW transformer grid test.
