Heron Power Secures $60M Credit Facility for Factory One

A factory starts consuming capital before it earns the right to call itself capacity. Heron Power has now put a $60M credit facility from J.P. Morgan and TriplePoint Capital between its engineering work and a planned late-2027 manufacturing ramp. The September 10 financing also brings former Tesla CFO Zach Kirkhorn onto Heron’s board.

The transaction matters because Heron’s risk is changing. Venture investors financed the power-electronics thesis and the factory plan; lenders are now entering while the company converts a 286,000-square-foot Morgan Hill warehouse into Heron Factory One. That is a different phase of company building, where product qualification, equipment, hiring, customer schedules, and the cost of capital all have to share one calendar.

Heron develops software-controlled medium-voltage power-conversion systems for AI data centers, utility-scale solar, and battery storage. The company says Heron Link can consolidate several pieces of conventional electrical equipment into a modular solid-state system. Heron has reported more than 40 GW of customer interest, but that figure describes interest, not signed orders, revenue, or deployed capacity.

What Heron Power secured

The $60M credit facility is being provided by J.P. Morgan and TriplePoint Capital. Heron did not disclose the interest rate, maturity, collateral, covenants, draw schedule, lender allocation, or how much was drawn when the deal was announced.

Those omissions set the boundary for interpreting the news. A credit facility gives a company the ability to borrow under agreed conditions; it is not automatically cash drawn in full, and it is not new equity. Heron previously raised a $38M Series A in May 2025 and a $140M Series B in February 2026. The new facility adds borrowing capacity and repayment obligations to a capital stack that had largely been explained through venture financing.

The company described the facility as support for its move from engineering toward manufacturing scale, but it did not publish an itemized use-of-proceeds plan. The safest reading is that Heron has expanded its balance-sheet flexibility ahead of a costly industrial ramp without revealing the economics or restrictions attached to that flexibility.

Why Heron Factory One changes the financing problem

Heron selected Morgan Hill, California, for Heron Factory One in August 2026. The company plans to convert a former 286,000-square-foot distribution warehouse into an advanced manufacturing site, invest more than $100M, and create more than 600 jobs. Site preparation has begun, while mass production is targeted for late 2027.

At full design capacity, Heron says the factory could produce up to 10,000 Heron Links and more than 40 GW of power-conversion equipment each year. California’s official incentive materials list a planned $140.9M company investment, 601 new jobs, and a $26.375M California Competes tax credit tied to the expansion.

This is the stretch where hardware companies discover that a factory is both an asset and a sequence of obligations. The building must be converted, equipment must be purchased and qualified, suppliers must arrive on schedule, workers must be hired and trained, and customers must accept the finished product. Financing has to carry those activities before the line produces repeatable revenue.

What Heron Link is designed to do

Heron Link is a modular solid-state power-conversion platform that connects medium-voltage electrical infrastructure with the lower-voltage systems used by data centers, solar projects, and battery storage. Heron’s data-center configuration converts 34.5 kV AC to 800 VDC and combines power conversion, protection, distribution, and short-duration ride-through functions that are commonly spread across several equipment categories.

Heron publishes different ratings for different configurations. Its solar and storage system is listed at 5 MW, while the current data-center page describes 4.2 MW of 800 VDC output. The company also reports efficiency, availability, footprint, and deployment advantages. These are vendor specifications and design claims, not independent evidence of commercial performance at Factory One’s planned scale.

The market case is still easy to understand. AI data centers, renewable generation, battery systems, electric vehicles, and new manufacturing loads all need electrical equipment that can move and convert more power. Traditional transformer supply has become a schedule constraint, while developers want equipment that is smaller, controllable, serviceable, and available from domestic production.

Heron’s opportunity is to make one architecture useful across several fast-growing customer groups. Its execution burden is to prove that modular power electronics can meet the reliability, certification, service, and cost expectations of infrastructure designed to operate for years, not demo cycles.

Why Zach Kirkhorn’s board appointment matters

Drew Baglino founded Heron in 2024 after nearly two decades at Tesla, where he led powertrain and energy work. Zach Kirkhorn spent 13 years at Tesla and served as CFO through its first full year of profitability and a major manufacturing expansion. Heron says Kirkhorn invested in its Series A and had already advised the company on financial and operating topics.

Moving Kirkhorn onto the board as institutional credit enters the picture joins two forms of operating memory. Baglino brings power-electronics engineering and manufacturing experience. Kirkhorn brings the financial perspective of scaling factories while capital requirements, margins, and production milestones remain in motion.

That does not assign Kirkhorn an operating role or disclose how the board will govern the credit facility. It does show that Heron is treating financial architecture and manufacturing execution as connected problems rather than separate departments that can reconcile later.

What the $60M facility signals

Heron says it has identified more than 40 GW of customer interest in Heron Link. That figure helps explain the factory ambition, but interest must still become contracts, qualified deployments, delivery schedules, and collections. The credit facility gives Heron more room to manage the crossing; it also introduces a financing clock alongside the production clock.

The company now has venture backing, a state tax-credit award, a factory site, two institutional lenders, and a board member who has worked through industrial scale. The next record will be built in physical milestones: equipment installed, products qualified, customers converted, units delivered, and Factory One moving from a 286,000-square-foot commitment into dependable output. Heron has financed more of that journey. The factory still has to make the calendar real.
