Fire breaks out at Greenidge mining facility co-hosting NYDIG rigs

Greenidge Generation Holdings, a Bitcoin (BTC) mining company, disclosed that a fire broke out at its mining facility in Dresden, New York, where it co-hosts operations with mining company NYDIG.

The fire broke out on Sunday due to an “electrical switchgear failure,” forcing the company to de-energize the entire facility, according to a Securities and Exchange Commission (SEC) filing.

The fire did not damage the mining rigs, and the company said it would resume normal operations within a “few weeks,” without providing specific dates.

Greenidge’s Dresden site generates 106 megawatts of natural gas energy to power its mining operations and machines co-hosted with NYDIG, according to TheMinerMag.

The downtime caused by the fire showcased the challenges of commercial mining operations, which operate on thin margins and must weather supply chain issues, high energy costs, equipment failures, dwindling block rewards, and regulatory hurdles to remain profitable.

The latest headwinds to hit the mining industry are straining miners even more

Hashprice, a critical metric for miner profitability that measures expected profits per unit of computing power, dropped to about $35 petahashes per second (PH/s) in November as BTC plunged to lows of about $80,000.

For context, mining operations typically become unprofitable around the $40 PH/s level. The hash price is back to about $39 PH/s at the time of this writing, according to Hashrate Index.

Stablecoin issuer Tether confirmed it shut down its mining operations in Uruguay on Tuesday, citing surging energy costs as the main reason for the exit.

The company was also in a dispute with a local state-owned energy provider over $4.8 million in unpaid energy bills and fees.

Bitmain, one of the leading mining hardware manufacturers, is now under investigation by US officials over national security concerns.

The officials are probing whether Bitmain’s application-specific integrated circuits (ASICs), the hardware used to mine proof-of-work (PoW) cryptocurrenccould be remotely accessed and used for espionageonage.

Bitmain is a Chinese company that has about an 80% market share of mining hardware, and any potential ban could make things even more challenging for the mining industry.
