It’s everyone’s dream to get paid to do nothing. Bitcoin miner Layer1 is turning that dream into reality — having figured out how to make money even when its machines are turned off.
Layer1 is a cryptocurrency startup backed by the likes of billionaire Peter Thiel. In recent months, out in the hardscrabble land of west Texas, the company has been busy erecting steel boxes (think shipping containers) stuffed chockablock with high-end processors submerged inside cooling baths of mineral oil. Why west Texas? Beause thanks to a glut of natural gas and a forest of wind turbines, power there is among the cheapest in the world — which is what you need for crypto.
“Mining Bitcoin is about converting electricity into money,” says Alex Liegl, CEO and co-founder. By this fall Layer1 will have dozens of these boxes churning around the clock to transform 100 megawatts into a stream of Bitcoin. Liegl says their average cost of production is about $1,000 per coin — equating to a 90% profit margin at current BTC price of $9,100.
So it’s odd how excited Liegl is about the prospect of having to shut down his Bitcoin miners this summer.
Already this year west Texas has seen a string of 100-degree days. But the real heat and humidity don’t hit until August, which is when the Texas power grid strains under the load of every air conditioning unit in the state going full blast. During an intense week in 2019, wholesale electricity prices in the grid region managed by the Electricity Reliability Council of Texas (ERCOT) soared from about $120 per megawatthour to peak out at $9,000 per mwh. It was only the third time in history that Texas power hit that level. And although the peak pricing only lasted an hour or so, that’s enough to generate big profits. Analyst Hugh Wynne at research outfit SSR figures that Texas power generators make about 15% of annual revenues during the peak 1% of hours (...
