ROCKDALE — Late final decade, the city of Rockdale appeared on the verge of financial break. The Alcoa aluminum plant there, which offered almost 1,000 jobs, closed in 2008. The Luminant coal-fueled energy plant shut down in 2017.
However now a brand new business has come to the city of about 5,300.
North America’s largest bitcoin mine — owned and operated by Whinstone U.S. — sits simply down the highway from the previous aluminum plant, about 60 miles northeast of Austin. The power, which has added about 145 jobs, hasn’t absolutely crammed the void created by Alcoa. However Whinstone U.S., which is owned by Riot Blockchain, is quick working to grow to be a staple of the neighborhood: It helped rebuild the native canine shelter. It put in lights at the highschool softball and soccer fields. It purchased the city’s 32-foot-tall Christmas tree. Rockdale Mayor John King famous the corporate funds livestreaming for the highschool sports activities occasions and donates fireworks for commencement.
Enlargement plans are within the works to greater than double the plant’s capability and make it the most important bitcoin mining facility on the planet, in line with Whinstone U.S. CEO Chad Everett Harris.

“I wish to see Texas grow to be the middle of the universe for bitcoin and crypto,” U.S. Sen. Ted Cruz, R-Texas, mentioned on the Texas Blockchain Summit, the place 700 attendees, in line with organizers, met in Austin on Oct. 8. There, Republican politicians made the case for the business alongside a lineup stuffed with entrepreneurs and researchers.
The budding business has its doubters. Skeptics fear concerning the large quantities of vitality required to mine bitcoin, which has spurred each environmental issues and fears concerning the pressure it might have an effect on Texas’ already fragile power grid.
And the expansion in Rockdale has are available matches and begins. In 2018, a Chinese language firm that designs specialised computer systems for cryptocurrency mining promised a whole bunch of jobs and a $500 million funding into the shuttered Alcoa smelter.
By the top of 2018, with the worth of bitcoin falling, these plans weren’t absolutely realized.
However Texas leaders are urgent ahead. Simply final week, Gov. Greg Abbott met with the Texas Blockchain Council. He tweeted afterward that the state quickly “might be #1 for blockchain & cryptocurrency.”
A “very pure synergy”
Cryptocurrencies are digital belongings that can be utilized to purchase sure services and products with out an middleman like a financial institution.

Most individuals purchase bitcoin on public exchanges. However new blocks of bitcoins are launched each 10 minutes, and miners compete to acquire them by a course of by which they resolve complicated math issues to validate transactions. These processes happen on blockchains, a public collection of decentralized, nameless blocks the place the small print get recorded. The extra computer systems a miner has competing within the course of, the extra bitcoins they will purchase, which makes mining an energy-intensive course of.
Whinstone U.S. hosts over 25,000 miners, or computer systems programmed to mine bitcoin. Energy runs by massive transformers related to these buildings, the place miners line racks upon racks. On the opposite aspect of these racks, an evaporative cooling wall pulls ambient air and coolant, dissipating the recent air emitted by the computer systems like a chimney.
To Texas Republicans and entrepreneurs, Texas and cryptocurrencies are an ideal pair. There’s a “very pure synergy,” Cruz mentioned, between blockchain and the state’s ethos, which he described as “give me a horse and a gun and an open flame, and I can conquer the world.”
Texas, he added, “lionizes” entrepreneurs. The state’s anti-regulatory legal guidelines attraction to the business, which values privateness. The cryptocurrency neighborhood, Cruz argued, is constructed on “particular person freedom, particular person accountability” and a scarcity of presidency dependence.
“We got here right here due to energy and the deregulated market,” Harris mentioned. “We knew energy was a aggressive element. And we knew at massive scale, we might get energy at a cheaper price.”
This 12 months, the Texas Legislature this 12 months took a number of steps towards rising the business right here.
HB 4474 acknowledged cryptocurrency within the state’s Uniform Industrial Code in an effort to set requirements that make clear the rights of people that management the forex and make it potential to resolve disputes over possession. The measure made Texas the third state to amend the legal guidelines regulating monetary transactions as such. HB 1576 established a 16-member working group that can advocate insurance policies regarding blockchain issues. Abbott signed each payments into legislation in June.
Vitality, setting and market volatility
China — the place about two-thirds of the country’s electricity comes from coal — has lengthy been the world chief in bitcoin mining. However the authorities there has not too long ago cracked down on these efforts, partly attributable to issues concerning the business’s affect on climate change.
Texas state leaders have shared few, if any, such issues.
The Whinstone U.S. mine has a capability of 300 megawatts — one megawatt is sufficient electricity to energy 400-900 houses in a 12 months — and hopes to succeed in a most capability of 750 megawatts upon growth. For politicians like Cruz, Texas’ abundance of vitality makes it fertile floor for an business the place bitcoin mining alone uses about as much energy annually as the Netherlands, in line with the Cambridge Bitcoin Electrical energy Consumption Index.
“For bitcoin, you want a number of vitality,” Cruz mentioned on the summit. “If there’s one factor Texas has in massive quantities, if there’s one factor Texas is aware of about, deeply, it’s vitality.”
However Texas noticed its energy grid overloaded throughout a lethal winter storm earlier this 12 months, elevating questions on whether or not the grid can deal with main progress in such an energy-intensive business.

Business advocates describe a symbiotic relationship between bitcoin miners and the Electrical Reliability Council of Texas, the state’s grid operator. They recommend the proliferation of blockchain know-how would assist stabilize a Texas energy grid that has more and more come underneath fireplace for failures throughout a storm that left an estimated 70% of Texans without power for an average of 42 hours.
The elevated demand introduced by mining might incentivize new sources of energy to come back on-line, they are saying. Bitcoin mining is just not steady, mentioned Lee Bratcher, president of the Texas Blockchain Council. The mines will be turned off at instances of excessive pressure on the grid — and ERCOT truly pays bitcoin mining corporations to stop actions in these moments. That unused energy from their base load demand is then pushed again into the grid, Bratcher added.
“Bitcoin mining is a load that can buy vitality 24/7. Nevertheless, it’s distinctive in that it has the flexibleness to show off in high-demand hours,” Riot Blockchain CEO Jason Les mentioned. “And by taking part within the grid with completely different companies for giant masses within the grid, we assist stabilize that grid as properly.”
Josh Rhodes, a research associate on the College of Texas at Austin who has consulted for a bitcoin mining firm, mentioned flexibility is essential. If cryptocurrency mines are prepared to cut back their vitality demand throughout instances of nice stress on the grid, then he mentioned they may have a helpful affect on the grid’s reliability.
Harris, the Whinstone U.S. CEO, mentioned his firm will be thought-about a “digital energy plant” that places vitality again into the grid throughout instances of excessive demand. The corporate has even turned its utilization off at instances when it might have been extra economical to proceed mining. Why? As a result of for a heavy person of electrical energy like Whinstone U.S., he mentioned, grid stability is extremely vital.
The business’s intensive vitality utilization additionally brings environmental issues. The advocacy group Atmosphere Texas has opposed politicians’ efforts to advertise the business, each for energy capability issues and due to the emissions created by producing energy to maintain the miners.
Govt Director Luke Metzger famous that some business advocates recommend they may put their corporations in areas with surplus renewable vitality. However, Metzger mentioned, such extra renewable vitality doesn’t exist in Texas.
“We’re very involved concerning the environmental impacts of simply including such an vitality intensive business that could possibly be taking over vitality that could possibly be used for extra vital functions,” Metzger mentioned.
Metzger additionally expressed issues round digital waste for an business that depends so closely on computing gear.
Even Tesla CEO Elon Musk — a bitcoin advocate who drew applause on the summit after Cruz toasted Tesla’s latest announcement that it’s going to transfer its headquarters to Austin — has had reservations. In Could, Musk announced Tesla had halted purchases of its automobiles with bitcoin, citing issues across the fossil fuels used to mine it.
Bratcher instructed Texas’ greener vitality choices make mining within the state extra sustainable than in China. Whereas he mentioned he’s cognizant of the environmental affect, he mentioned that bitcoin mining in Texas depends 30% on renewable vitality. Twenty p.c of the state’s vitality comes from wind power. Lower than 15% of bitcoin mining within the state makes use of coal, he added.
However these numbers aren’t ok, in line with Benjamin A. Jones, a College of New Mexico economics professor who has researched cryptocurrency mining’s environmental affect. He pointed to a September 2020 University of Cambridge study, which estimated 39% of mining is powered by renewable vitality. Jones mentioned that determine would put Texas under the worldwide common in the case of renewable mining. Coal and pure fuel account for 38% and 36% of energy sources, respectively.
His personal research, he mentioned, discovered “very excessive” environmental and local weather damages related to mining operations at 20% to 30% renewable vitality utilization.
Wanting forward
Business leaders are set on remodeling the political panorama for blockchain know-how.
On the Oct. 8 summit in Austin, David Zell, head of coverage and public affairs at Bitcoin Journal, introduced the launching of a brilliant PAC devoted to swaying public opinion on cryptocurrency.
“Bitcoin has a story drawback,” he mentioned.
Bratcher shared plans for a future modification to the Texas Structure that might permit Texans to pay property taxes in bitcoin. State Reps. Tan Parker and Gio Capriglione, each Republicans, endorsed the concept in a dialog with Bratcher on the summit.
On the summit, lawmakers and advocates even explored the concept of utilizing blockchain know-how past the world of finance. Along with getting used for property taxes, the know-how might assist safe well being care data and even defend elections, they mentioned.
“You guys are pioneers on the entrance traces of an awfully shiny new future,” Parker informed the viewers. “When you concentrate on the transformational affect of the web from 20-25 years in the past, I feel blockchain may have a better affect.”
In Rockdale, the affect has introduced “a number of curiosity in our neighborhood,” King, the mayor, mentioned. Along with the native labor the businesses use, King mentioned the worldwide publicity they’ve introduced now has different corporations contemplating finding there.
“They’ve all been good neighbors from that standpoint,” King mentioned. “They have not had [a] actual damaging affect in any respect. If something, it has been constructive.”
