Hallador Energy Closes $600M Loan to Build Turtle Creek Plant

Hallador Energy Company (NASDAQ:HNRG) closed a $600 million senior secured term-loan facility on September 15, the company announced on September 17. Roughly $550 million funded at closing, with a conditional $50 million delayed draw available over the following 12 months.

The money backs the proposed 460-megawatt Turtle Creek natural gas power plant, a project with an estimated total cost below $800 million. About $120 million of the loan will refinance existing facilities. That arithmetic defines the investment case: the truly incremental capital is far smaller than the headline number, and the debt carries a steep price.

What the $600 million actually buys

Subtract the $120 million refinancing from the initial $550 million draw and Hallador has roughly $430 million in fresh capital before fees and other uses. Drawing the remaining $50 million would lift that figure to $480 million. A potential additional $75 million revolver, cited by the company, still needs to be established.

Measuring the remaining funding gap also requires accounting for construction costs still to be paid, spending already incurred, and available corporate cash — figures the announcement did not fully specify.

The loan proceeds cover equipment payments, transportation, refurbishment, and construction preparations for Turtle Creek. That reduces uncertainty around the next development stages of the project, which targets commercial operation in the second half of 2028.

The capital-efficiency argument

Management's case for building the plant cheaply rests on existing infrastructure and generation equipment already under contract. Reusing those resources could shorten the development timeline and cut costs, expanding Hallador's power-generation business while diversifying its fuel mix beyond coal.

Existing operations provide a second funding lever. As of June 30, contracted future revenue totaled $1.8 billion from external customers, or $2.4 billion including intercompany coal sales. Those commitments stretch through 2040 — well beyond Turtle Creek's planned startup.

Construction funding therefore depends on cash generated before the plant enters service, after operating costs, working capital needs, and other spending. Management aims to complete the financing with little to no equity dilution, preserving existing shareholders' participation in future earnings.

The cost of the money

Borrowing costs are substantial. Before commercial operation, annual interest consists of two components: 3.5% payable in cash, and the Secured Overnight Financing Rate (SOFR) plus 4.5% payable through capitalization — adding that entire component to the loan balance. A 3.5% SOFR floor produces a minimum combined interest rate of 11.5%, excluding fees.

That structure means the debt compounds while the plant generates no revenue. Every quarter of delay in the second half of 2028 startup window adds capitalized interest to a balance that already exceeds half a billion dollars.

The balance sheet test

The bull and bear cases turn on the same numbers. Hallador has funded capital in place, a $1.8 billion contracted revenue base through 2040, and management committed to avoiding dilution. Against that sits approximately $430–480 million of genuinely new money, an unestablished $75 million revolver, an unspecified residual funding gap, and a minimum 11.5% interest rate running from day one.

The next visible checkpoints are the revolver's establishment, progress payments on the plant's construction schedule, and cash generation from the coal business as Turtle Creek approaches its 2028 target.
