According to TheMinerMag, Bitcoin mining company Stronghold Digital has been fined over $1.40 million by the Federal Energy Regulatory Commission (FERC) for violating energy market rules and prioritizing electricity supply for Bitcoin mining. Of this amount, $678.60 thousand must be refunded to PJM, and $741.40 thousand will be paid as a civil penalty to the U.S. Department of the Treasury. FERC's investigation found that Stronghold's Scrubgrass power plant failed to fulfill its contractual obligation to provide available power to the PJM grid from June 2021 to May 2022, diverting electricity for Bitcoin mining during 57% of day-ahead market trading hours and 59% of real-time market trading hours. Additionally, Stronghold was accused of purchasing electricity at wholesale prices and incorrectly classifying some of its electricity usage as "station power." Stronghold exited the PJM capacity market in June 2022, but it may still be required to participate in future auctions unless it formally applies for an exemption or shifts to providing only energy resources.
