Marathon’s 280 kW Utah Landfill Gas Pilot Runs at 92% Uptime, $0.03/kWh

Marathon Digital has switched on a small Bitcoin mining pilot in Utah that runs entirely on electricity generated from landfill methane, reporting 92% uptime and a power cost of roughly $0.03 per kWh. The facility, built with energy partner Nodal Power, has a capacity of 280 kW — about 0.28 MW — a fraction of the hashrate a major miner typically deploys, but the economics behind it are the real story for an industry under constant pressure to cut its power bill.

The numbers behind the pilot

Marathon’s disclosed figures are modest but specific: a 280 kW off-grid site, 92% operational uptime, and power costs around $0.03 per kWh. For context, that price point sits well below typical grid electricity rates paid by miners in most US markets, where costs commonly run several times higher depending on region and time of day.

The setup captures methane gas escaping from a landfill — a byproduct that would otherwise vent or flare as waste — and converts it on-site into electricity to power mining hardware, without drawing from the public grid. Nodal Power supplied the generation infrastructure that makes the conversion possible.

Why 280 kW matters more than it sounds

At 0.28 MW, this pilot is nowhere near the scale of Marathon’s flagship mining sites, some of which run into hundreds of megawatts. But the point of the project isn’t hashrate — it’s proving a cost model. If methane that a landfill operator must otherwise manage as an environmental liability can instead be converted into sub-$0.03/kWh power at 92% uptime, that’s a data point miners can use to evaluate similar off-grid deployments elsewhere.

Landfill methane is a potent greenhouse gas when released untreated, so capturing it for power generation carries an environmental argument alongside the cost one. For a mining sector that faces recurring scrutiny over energy sourcing, a documented uptime and cost figure from a live pilot — rather than a projection — gives Marathon a concrete reference point to point to.

What it means for miners watching power costs

Power cost per kWh is the single biggest variable in Bitcoin mining profitability, and a verified $0.03/kWh figure at 92% uptime is a useful benchmark for the industry, even at small scale. If the pilot’s numbers hold as Marathon or other operators look to replicate the approach at larger landfill sites, waste methane could become one more entry in the growing list of unconventional, low-cost power sources — alongside flared natural gas and stranded renewables — that large-scale miners are testing to squeeze out margin as network difficulty keeps rising.

For now, the Utah site remains a pilot rather than a blueprint. But the disclosed uptime and cost figures give the market its first hard data points on whether landfill gas can be a viable, scalable power source for Bitcoin mining rather than just a talking point.
