Sterling Digital (AQSE:ASIC), which is developing low-cost digital asset mining operations in the United States, said both of its 2 MW Caterpillar natural gas generators are now running and producing electricity at its West Texas site.
The commissioning programme has moved past initial start-up of the individual generators and into integrated testing of the full power plant, which also includes gas supply and regulation systems, cooling and lubrication systems, switchgear, control systems and power-distribution infrastructure.
Each subsystem is being brought online in sequence and validated against the rest of the plant before commercial operations begin.
Sterling's five-year Gas Purchase Agreement secures up to 6,500 MMBtu of pipeline gas per day, enough to support up to 25 MW of computing capacity and a path for expansion beyond the current build.
The next milestone is energisation of Sterling's fleet of 420 ASIC mining servers, representing approximately 193,500 terahashes per second of capacity, ahead of the start of Bitcoin production.
By generating power on-site from contracted low-cost gas, Sterling controls the principal variable cost in Bitcoin mining rather than relying on grid electricity.
"We are not simply delivering two generators, connecting them and switching them on, the ambition was greater than that. We have built a complete power plant from the ground up," said Stefan Michaelides, CEO of Sterling Digital.
Michaelides said the company expects to provide further updates in the coming weeks as the project moves toward full production readiness.
News Intelligence what this means for the company
Sterling Digital has moved its West Texas mining site past initial generator start-up into integrated plant-wide testing, with both 2 MW Caterpillar units now running and producing electricity. This is a concrete step toward the next milestone—energising 420 ASIC servers representing 193,500 terahashes per second—ahead of Bitcoin production expected 12 August 2026. The company is validating all subsystems (gas supply, cooling, switchgear, control) in sequence before commercial operations, de-risking the path to revenue generation from on-site, low-cost gas-powered mining.
Commissioning progress reduces execution risk on the company's core thesis: controlling Bitcoin mining's principal variable cost (electricity) through vertical integration of on-site gas-to-power generation. The move from isolated component testing to full plant validation is a material step, though revenue generation remains contingent on successful server energisation and stable Bitcoin production in the coming weeks.
