The facility now operated as Greenidge Generation in Upstate New York began in 1937 as a coal-fired power plant, commissioned by New York State Electric and Gas Corporation. AES Corporation purchased the plant in 1999 which continued to operate until 2011.

In 2014, a group of private investment funds sponsored and managed by Atlas Holdings LLC purchased the Greenidge plant.

Greenidge established itself as a leader in environmental stewardship by converting from a coal-fired operation to one powered by clean-burning natural gas. Greenidge spent several years securing the necessary state and federal permits and approvals and underwent a rigorous environmental assessment in advance of resuming operations at its New York facility.

Greenidge operates entirely within all relevant permits and local ordinances for its facility, including a State Pollution Discharge Elimination System water permit and a Title V Air Permit. Greenidge operates entirely on natural gas, resulting in reduced greenhouse gas emissions, and the company has invested heavily in reliable, verifiable carbon offset credits to ensure it maintains net-zero carbon emissions in its bitcoin transaction processing operations.

The Greenidge facility provides a clean, reliable source of power to New York state’s energy grid: powering up to 20,000 homes and businesses in the region. Following an assessment of demand levels from the state’s energy grid, Greenidge launched its first commercial bitcoin transaction processing operation in 2020.

Greenidge has worked closely with its local community to ensure its operation is both environmentally sound and supportive of the community’s energy and economic needs. Between 2014 and 2020, Greenidge’s capital investments, directly and indirectly, supported approximately 200 jobs in New York State in construction and related industries, with over $13 million in employee earnings. During the 2020 COVID-19 pandemic, Greenidge’s spending supported over 80 businesses in the Finger Lakes Region of New York.

Greenidge is committed to expanding its operations in North America with an emphasis on renewable power while remaining dedicated to being 100% carbon neutral. In June 2021, Greenidge announced that it would expand its transaction processing operations beyond New York to South Carolina in a facility that will source the majority of its power from zero-carbon sources.
