Greenidge Generation Holdings Inc.

Greenidge Generation Holdings Inc.

Greenidge Generation Holdings was formed in 2019 as a single-family-office-backed vehicle to acquire and operate the Greenidge natural gas power plant in Dresden, New York. The facility was originally a coal-fired plant shut down in 2011; the ownership group converted it to natural gas and later added an on-site Bitcoin mining data center, effectively linking power generation to digital asset production. The firm operates across two interconnected sectors: energy production and cryptocurrency mining. At the plant, natural gas turbines generate up to 106 MW, of which around 50 MW powers a proprietary Bitcoin mining operation using over 20,000 mining rigs (per company investor presentations, 2022). Greenidge also sells excess power to the NYISO grid. The strategy captures multiple revenue streams — selling electricity to the grid, earning Bitcoin from mining, and potentially hedging with power price arbitrage. The firm’s asset base is concentrated in North America, primarily New York, with additional data center development efforts in South Carolina (per SEC filings, 2023). Greenidge went public in September 2021 via a merger with a SPAC, raising approximately $150 million. As of mid-2023, the firm employs around 50 people across its Fort Lauderdale headquarters and Dresden site. It also maintains a registered investment adviser subsidiary, NYDIG, though the exact relationship is complex. In 2022, the New York Department of Environmental Conservation denied renewal of the plant's Title V air permit, forcing the firm to cease mining operations at the Dresden site for a period — though mining subsequently resumed under a limited operating permit (per the NY DEC, 2022). Greenidge’s structural differentiator is its vertical integration of power generation and digital asset mining — a model that drives variable cost advantages for Bitcoin production. The plant's own capacity to generate energy reduces external electricity costs, a primary expense for miners. The ownership group is structured as a single-family office, with the underlying wealth derived from industrial and infrastructure holdings. Governance is concentrated among the founding family office principals, with no external institutional investors disclosed.
