What Heron Power does

Heron Power is a U.S.-based power electronics company founded in 2024 by Drew Baglino (former Tesla SVP of Powertrain and Energy, 18-year Tesla veteran) to develop modular medium-voltage solid-state transformers (SSTs) for AI data centers, utility-scale solar and storage, and grid applications. The company targets structural shortfalls in conventional iron-core transformer supply — 24-month lead times and 60-80% price increases since 2020 — and the inability of passive equipment to handle dynamic AI training load fluctuations.

The core product is the Heron Link platform, built on silicon carbide (SiC) MOSFETs and gallium nitride (GaN) semiconductors switching at hundreds of kHz. The platform is delivered in two variants: Heron Link for Data Centers (4.2 MW, converting 34.5 kV AC medium voltage to 800 V DC at 98.5% efficiency, with integrated SuperBBU battery buffer for AI training ripple mitigation and 30-second ride-through) and Heron Link for Solar & Storage (5 MW integrated SST-inverter at 98.6% DC-to-MV efficiency, 99.5% availability, 20-year warranty). Each Link comprises thirty 140 kW power cells with fail-operational redundancy and a solid-state circuit breaker clearing faults in under 5 microseconds. The architecture consolidates voltage conversion, fault isolation, power factor correction, frequency regulation, harmonics control, and phase balancing into a single firmware-upgradable package. Additional products include the HeronCare service program (10- to 20-year coverage with predictive analytics) and OpenVSM, an open-source inverter-controls initiative.

Heron Power operates a direct enterprise sales model with no resellers, targeting hyperscale data center operators (publicly Crusoe, via LOI for the Stargate AI infrastructure project), utility-scale solar/storage developers (Intersect Power), and grid operators. The business model is hardware sales supplemented by long-duration service contracts. As of early 2026 the company is pre-revenue (SEC Form D explicitly declines to disclose revenue), with pilot production targeted for early 2027 and full-scale production in 2H 2027 from a planned 40 GW annual-capacity California manufacturing facility. Total funding of $178M ($38M Series A May 2025, $140M Series B February 2026) plus a $26.375M California Competes Tax Credit supports the capacity buildout. Customer interest reportedly exceeds 40-50 GW prior to scaled production, and the company is partnered with NVIDIA (800 VDC ecosystem) and LG Energy Solution Vertech (co-engineered storage integration).

Revenue model

1. Hardware Sales (Heron Link Solid-State Transformers): Pre-revenue as of early 2026. Revenue will primarily come from selling Heron Link solid-state transformer units (4.2 MW for data centers, 5 MW for solar/storage) and integrated SuperBBU battery skids to enterprise customers in utility-scale solar, energy storage, data center, and grid applications. Customer backlog already exceeds 40-50 GW of orders prior to scaled production. Pilot production begins early 2027 with full-scale production in 2H 2027 from a planned 40 GW annual capacity U.S. manufacturing facility.
2. Service & Warranty (HeronCare): Long-term service contracts covering parts, labor, and predictive analytics. HeronCare covers 10-year parts & service for Data Center product and 20-year parts/labor for Solar & Storage product with predictive analytics to maximize uptime and reduce total cost of ownership.

Core offering

Heron Power develops and manufactures modular medium-voltage solid-state transformers (Heron Link) and integrated power electronics hardware for AI hyperscale data centers, utility-scale solar, and grid-scale battery storage. The Heron Link platform converts 34.5 kV AC medium voltage to 800 V DC (Data Centers) or to MV AC (Solar & Storage) at 98.5%+ efficiency using silicon carbide semiconductors and software-defined controls, replacing conventional iron-core transformers, switchboards, UPSs, and PDUs with a single integrated unit.

Product overview

Heron Power's offering centers on a single platform — Heron Link — a modular medium-voltage solid-state transformer (SST) that is delivered as two application-specific configurations: Heron Link for Data Centers (4.2 MW, 34.5 kV AC to 800V DC with integrated SuperBBU battery buffer for AI/hyperscale power) and Heron Link for Solar & Storage (5 MW integrated SST and inverter for utility-scale PV and storage). Together these two Heron Link variants form the core product portfolio, sharing the same power-electronics hardware platform and HeronCare predictive-analytics service program (10-year coverage for data centers, 20-year for solar and storage). Layered on top, OpenVSM (Open Virtual Synchronous Machine) extends the platform into an open-source inverter-controls software layer for universal grid stability, and SuperBBU is an integrated add-on module inside the data-center Heron Link variant that mitigates AI training load ripple and provides ride-through backup.

Broad incumbents

• Hitachi Energy: Global incumbent in transformers and grid hardware with established utility relationships, full product portfolio including conventional transformers and emerging solid-state/semiconductor-based offerings. Directly comparable because it sells to the same hyperscale data center, utility, and renewable developer customers Heron targets, but at multi-decade scale and with broader portfolio breadth.
• Siemens Energy: Major transformer manufacturer with grid technologies and an active SST/power-electronics program. Comparable to Heron in addressing the same grid-modernization bottleneck for data centers and renewable developers, but with global scale, utility certifications, and a much broader product line.
• GE Vernova: Spun out of GE as a focused power and grid equipment OEM including transformers and grid solutions. Competes with Heron for hyperscale data center power infrastructure contracts and utility-scale projects, with significantly larger manufacturing scale and an established service backlog.
• ABB: Global electrification and grid automation leader with substantial transformer and power-electronics offerings including solid-state circuit breakers and grid-forming inverter products. Overlaps with Heron in medium-voltage conversion, grid-forming controls, and AI data center power chains, but at full-portfolio scale.
• Schneider Electric: Global energy management and data center infrastructure provider with transformers, UPS systems, PDUs, and switchgear that Heron's Heron Link consolidates into a single device. Direct competitive overlap on data center power distribution, especially for AI/hyperscale customers, but Schneider bundles across the full electrical stack.
• Eaton: Power management company with strong data center electrical infrastructure portfolio (UPS, switchgear, power distribution) that Heron Link directly displaces. Comparable customer base (hyperscalers, colos, utilities) with established service network, though Eaton's portfolio remains discrete rather than consolidated silicon-based.

Direct peers

• Smart Wires: Startup focused on grid-enhancing technologies including modular power flow control and solid-state solutions for utilities. Directly comparable to Heron as a power-electronics startup attacking the same transformer/grid-flexibility bottleneck, though Smart Wires is more focused on transmission utilities than data centers.
• Resonac (formerly Showa Denko): Japanese materials and power-electronics company developing SiC-based solid-state transformer solutions for grid applications. Directly comparable to Heron's SiC MOSFET-based medium-voltage SST platform and serves similar utility and renewable integrator customers.

Others

• Tesla (Energy business / Megapack): Founder/CEO Drew Baglino's prior employer and the spiritual parent of Heron's grid-electronics approach. Tesla Megapack and energy products are adjacent (utility-scale battery storage) but represent a partnership/channel opportunity rather than direct competition; Tesla's inverter and transformer supply constraints effectively hand demand to specialists like Heron.
• Fluence Energy: Major utility-scale battery energy storage system integrator and a complementary rather than competing channel for Heron's Solar & Storage Heron Link variant. Comparable in being a fast-growing grid-modernization company serving the same solar/storage developer customers, though Fluence focuses on the storage system integration layer rather than MV power conversion hardware.
