Bitcoin mining is quietly turning wasted energy into profits in Wyoming — and it could reshape miner economics post-halving. Compass Mining has switched on an off-grid site powered by stranded natural gas, built with 360 Energy. Beyond the headline, the real story is about reviving older ASICs like the S19-series, cutting costs with off-grid power, and building toward institutional-scale deployments that decouple mining from stressed grid markets.

What’s happening

Compass Mining launched its first off-grid natural gas facility in Wyoming with 360 Energy, already running and set to be fully energized by the end of September 2025. The site brings 3.3 MW of capacity and is designed to redeploy earlier-generation Antminer S19 hardware — extending its useful life and turning idle machines into revenue assets. The move advances Compass’s vertical integration and diversifies energy sources amid record global flaring volumes (~150 bcm in 2024).

Why it matters to traders

- Off-grid strategies lower OPEX and volatility, supporting miner margins in a tight, post-halving environment. - Redeploying S19s signals that ultra-low-cost power is being secured; this can stabilize hash supply and cap extreme miner capitulation risk. - Institutional-grade off-grid products can attract new capital and create differentiated miner equities.

Hashrate and profitability signals

At 3.3 MW, an S19-based fleet (≈30 W/TH, depending on firmware/undervolt) implies roughly ~100–130 PH/s incremental hashrate. While small vs. network size, it’s a proof-of-model: monetizing pipeline-constrained gas can price power near a few cents/kWh, keeping older rigs profitable. Watch for similar deployments to scale — each megawatt of low-cost off-grid capacity extends the floor under miner economics and may dampen extreme hashprice drawdowns.

Who could benefit — and how to position

• Bitcoin miners: Operators with stranded-gas or off-grid footprints may show higher uptime and lower OPEX vs. pure on-grid peers.
• Used-ASIC markets: Sustained demand for S19-class machines can support secondary prices; track premiums/discounts to hashprice.
• Infrastructure/energy partners: Firms offering gas offtake (like 360 Energy) can become leverage points for miner growth.
• BTC price participants: More resilient hash supply reduces forced-sell risk in stress periods, subtly improving BTC market structure.

Key risks to the thesis

• Regulatory scrutiny: Rules on flaring, emissions accounting, or off-grid permits could tighten.
• Operational variability: Gas supply interruptions, site uptime, or logistics can erode expected margins.
• ASIC efficiency gap: Next-gen rigs may outcompete older hardware if power isn’t ultra-cheap.
• Commodity swings: Local gas dynamics or offtake terms can shift the power-cost advantage.

Data to track

• Hashprice (USD/PH/day) trends and miner revenue sensitivity post-halving.
• ASIC efficiency spreads: S19 vs. S21/T21 profitability under off-grid rates.
• Compass expansion cadence: MW added off-grid and institutional client uptake.
• Flaring data: Growth in captured volumes indicates runway for scale.

One actionable takeaway

If you trade miner equities or allocate to mining, prioritize operators with secured low-cost, off-grid energy. Validate with real metrics: contracted MW, uptime, all-in power cost, and fleet efficiency. Hedge revenue risk using BTC options/futures or hashrate derivatives where available to stabilize cash flows through difficulty and fee volatility.

The bottom line

Off-grid gas offtake is evolving from niche to strategy. By converting wasted energy into compute, Compass and 360 Energy showcase a path to sturdier miner margins, extended hardware life, and more resilient network security — a structural tailwind traders shouldn’t ignore.
