Greenidge announces closure of Lockwood Hills landfill in Dresden

Greenidge Generation Holdings Inc. announced last week that it will be investing profits from its bitcoin mining operation in Dresden, New York to expedite the closure of an existing, forty-year-old coal ash landfill. They will also create a significant new solar farm at the site. The Lockwood Hills landfill was acquired by Lockwood Hills LLC, a subsidiary of Greenidge Generation Holdings Inc., in 2014 and has been maintained by the company over the past seven years.

During that  period, the company ended the use of coal-fired power at its adjacent power generation  facility.

The company intends to work with the New York State Department of Environmental  Conservation to close the landfill and relinquish its existing permit to operate the site. Greenidge will launch a Request for Proposals to identify the best option for creating a solar project across the 143-acre site that will produce up to 5MW of power.  

In May of this year, Greenidge announced that it was purchasing voluntary carbon offsets from a portfolio of U.S. greenhouse gas reduction projects to create the first fully  carbon-neutral bitcoin mining operation of its kind in the United States. At the same time,  The company said it was actively exploring investing a portion of its mining profits in renewable  energy projects in New York. 

“Bitcoin mining at Greenidge is already a model for the industry in that we are  advancing this emerging financial platform for people across the world in a manner that fully  protects our environment and drives economic growth across Upstate New York. Today, we’re announcing the next step; making more renewable energy a reality by leveraging bitcoin mining  profits to fund the creation of a new solar farm at a landfill site we’re going to close well ahead  of schedule,” said Jeff Kirt, CEO of Greenidge Generation Holdings Inc.  


“For those of us who grew up and still live right here in the Finger Lakes, the Lockwood  Hills landfill has been a constant presence, overlooking Seneca Lake and the Village of Dresden,  and something we always hoped would eventually not be needed. I am thrilled that the success of our clean bitcoin mining operation is not only creating great high-tech jobs for residents here,  and supporting local businesses, but will now also facilitate the development of renewable  energy at this old landfill site,” said Dale Irwin, President of Greenidge Generation Holdings Inc.   

The Lockwood Landfill was initially constructed and permitted in 1979 to dispose of coal  combustion residuals (CCR) and other wastes generated by the power generation facility prior to Greenidge assuming ownership in 2014.

Today, while Greenidge has ended the use of coal as  a fuel source for its clean natural gas fired operation, the Lockwood Landfill remains open and  operational. It operates in strict compliance with two comprehensive New York State DEC  permits; a Part 360 Solid Waste Management Permit and a State Pollutant Discharge Elimination System Permit. In 2017 and 2018, upgrades to the stormwater and leachate  management systems were completed by Lockwood Hills at a cost of over one million dollars. In  addition to ensuring that the site will no longer accept waste of any kind, the closure process  will entail several steps including site grading and the installation of a permanent engineered  membrane to prevent erosion and water infiltration.
