Bitdeer Adds 7 MW in Texas, Lifting Soluna's Kati 1 to 35 MW and 2.42 EH/s

Why is Bitdeer adding machines to a Texas wind farm before the first phase is even fully plugged in?

That's the question worth asking after Soluna's September 28 announcement. Bitdeer is tacking on roughly 7 MW of mining gear at Project Kati 1 in Willacy County, Texas. The amendment lifts Bitdeer's total planned deployment at the site from 28 MW to 35 MW, and the company expects to reach about 2.42 EH/s once everything's humming.

Here's the part that stands out. The original 28 MW agreement was announced in August. One month later, they're already adding capacity. That's not a pilot anymore. That's a commitment.

The Raw Numbers

Let's stack the figures. Project Kati 1 is an 83 MW facility tied to wind generation in South Texas. Bitdeer's slice climbs to 35 MW. The hardware is Bitdeer's own Sealminer A2 Pro Air rigs, which the company supplies and owns outright. Soluna brings the site, the power, and the operating infrastructure. Then the two split the mining proceeds.

Deployment of the extra 7 MW is slated for November. The amendment also fully subscribes the K1BC phase of the project, which means that section of the site is now spoken for. No remaining room in that block.

So we're looking at 28 MW signed in August, 35 MW by November, and 2.42 EH/s of hash rate at a wind-powered site in one of the cheapest power markets in North America. Those are the facts. Now the interesting part.

Why Curtailed Power Is the Real Story

Most mining deals are hosting arrangements. A host gets paid for rack space and megawatts, full stop. The miner eats the Bitcoin price risk while the host collects a fee. Clean, boring, predictable.

Soluna's structure isn't that. It's co-mining. The company takes a cut of the actual Bitcoin produced, which means it's exposed to the same price and difficulty swings as Bitdeer. That's a very different bet, and it only makes sense if you believe two things. First, that mining stays profitable enough to beat a fixed hosting fee. Second, that Soluna's core edge, siting compute next to renewable generation that would otherwise be curtailed, actually holds up.

That second point is the whole thesis. Texas wind routinely produces more electricity than the grid can absorb, especially overnight. Curtailed power is wasted power. Put a load right next to it and you're buying energy at prices most miners can't touch. The regulatory map just shifted on energy in this state, too, and the patchwork of curtailment rules sits right underneath deals like this one.

But here's a take. Co-mining sounds clever until it doesn't. When Bitcoin's price drops 30% and network difficulty keeps grinding higher, Soluna's revenue falls right alongside Bitdeer's. A traditional host would've kept collecting its fee through the whole drawdown. So sure, the structure aligns incentives. It also doubles the downside. That's not a knock on the deal, it's just the trade.

So who's really carrying the risk here? Not the equipment owner. Not the grid. Mostly the two parties who agreed to share the outcome instead of locking in a spread.

What the Operators Are Betting On

For Bitdeer, the logic is simpler. It gets 35 MW of capacity without building a site from scratch, which in Texas means without fighting interconnection queues, land deals, and permitting timelines that can stretch 18 to 24 months. In these arrangements, that speed is the entire point. Capital follows clarity, and the clearest path to more hash rate right now runs through someone else's already-energized footprint.

Traders are watching hash rate announcements closely because they're a decent leading indicator of where network difficulty goes next. Bitdeer jumping from 28 MW to 35 MW in a month is a small data point on its own. Repeat it across a dozen operators and it starts to bend the difficulty curve in a direction smaller miners won't enjoy.

Is that bullish? Depends on your framing. More efficient hash rate coming online is healthy for network security. It's less healthy for anyone running older machines on thin margins. Someone's getting squeezed. It isn't the operator with A2 Pro Air rigs sitting on curtailed wind prices.

What to Watch

First, November. If the 7 MW lands on schedule, that's a clean execution signal and it strengthens the case for another expansion at Kati 1 or a sister site. Slippage into December or the first quarter would say something less flattering about the supply chain for those A2 Pro Air units.

Second, the curtailment economics across ERCOT. Watch the spread between day-ahead power prices and what Soluna's actually paying at the fence. If that spread widens, co-mining gets more attractive and expect copycats. If it narrows, the pitch gets harder to sell.

Third, the math on the rest of the building. Bitdeer's 35 MW is only about 42% of Kati 1's 83 MW, which leaves 48 MW unallocated. Soluna has been hinting at positioning these sites for high-performance computing beyond Bitcoin. HPC pays better per megawatt than hashing does, when you can land the contract, and that's the real upside sitting in the empty half of the facility.

Bitdeer didn't have to add this 7 MW. It chose to, one month after signing, at a site where phase one hasn't finished ramping. That's the story. Not the megawatts. The speed.
