Our power and capacity revenue decreased $9.5 million, or 59%, to $6.7 million in 2023. We estimate that lower power and capacity sales volume due to our increased behind-the-meter consumption and lower average power and capacity prices caused revenue decreases of approximately 7% and 52%, respectively.
Our power and capacity revenue increased $4.0 million, or 59%, to $10.6 million in 2024. We estimate that higher power and capacity sales volume due to increased demand and higher average power and capacity prices caused revenue increases of approximately 23% and 36%, respectively.
The main drivers of the decrease in selling, general and administrative expenses were: • Decrease of approximately $4.4 million due to reductions in professional fees and consulting expenses caused by reductions in discretionary costs and higher regulatory costs in the prior year associated with permit renewals and environmental matters at the New York plant; and • Total payroll and benefits and other employee costs decreased approximately $2.7 million in 2023 compared to the prior year, as a result of declines in employee expenses including incentive compensation; and 62 • Decrease of approximately $1.9 million due to a combination of reductions in marketing, facilities, travel, and various other selling, general and administrative expenses; and • Total business development and other related costs decreased approximately $0.6 million in 2023 as compared to the prior year, mainly as a result of declines in spending in regards to public relations; and • Total insurance expense decreased approximately $0.5 million in 2023 compared to the prior year, as a result of declines in coverage costs related to umbrella, property, and liability policies; and • Total property taxes decreased approximately $0.4 million in 2023 compared to the prior year, as a result of a reduced property tax liability relating to a PILOT agreement with a local government as well as a reduction in property taxes relating to the sale of the South Carolina facility; and • Total stock compensation decreased approximately $0.3 million in 2023 compared to the prior year, as a result of a decline in amortized expense relating to RSUs with a higher grant date fair value, which was offset partially by an increase in amortized expense relating to options granted in prior periods.
The main drivers of the decrease in selling, general and administrative expenses were: • Total restructuring costs decreased approximately $4.1 million in 2024 compared to the prior year, mainly as a result of non-recurring restructuring costs incurred in the prior year; • Total payroll and benefits and other employee costs decreased approximately $1.2 million in 2024 compared to the prior year, as a result of declines in employee expenses including incentive compensation as result of the restructuring activities in the prior year to reduce our cost structure; • Total insurance expense decreased approximately $2.2 million in 2024 compared to the prior year, as a result of declines in coverage related to umbrella, property, and liability policies; • Total legal costs decreased approximately $1.2 million in 2024 compared to the prior year, as a result of declines in attorney and legal counsel fees, primarily as a result of fewer significant transactions in 2024, as compared to 2023; • Total stock compensation decreased approximately $0.5 million in 2024 compared to the prior year, as a result of a decline in amortized expense relating to RSUs with a higher grant date fair value, which was offset partially by an increase in amortized expense relating to options granted in prior periods.

We have classified the Support.com business as held for sale and discontinued operations in the consolidated financial statements as a result of a strategic shift to strictly focus on our cryptocurrency datacenter and power generation operations. In January 2023, Greenidge completed the sale of a portion of the assets of Support.com for net proceeds of approximately $2.6 million.
As a result, we have classified the Support.com business as held for sale and discontinued operations in these condensed consolidated financial statements as a result of management and the board of directors making a decision to pursue alternatives for the Support.com business and to strictly focus on its cryptocurrency mining, datacenter hosting and power generation operations.
We own cryptocurrency datacenter operations in the Town of Torrey, New York (the "New York Facility"). The New York Facility is a vertically integrated cryptocurrency datacenter and power generation facility with an approximately 106 -megawatt ("MW") nameplate capacity, natural gas power generation facility.
The New York Facility is a vertically integrated cryptocurrency datacenter and power generation facility with an approximately 106 MW nameplate capacity, natural gas power 50 generation facility. We generate revenue from four primary sources: (1) datacenter hosting, which we commenced on January 30, 2023, (2) cryptocurrency mining, and (3) power and capacity.
Gain on sale of assets We recognized a gain on the sale of assets of $9.9 million for the sale of certain credits and coupons during the year ended December 31, 2023, which includes the $1.2 million of coupons transferred to NYDIG as part of the debt restructuring and the $8.2 million related to the sale of the South Carolina Facility.
This is compared to a gain on sale of assets of $9.9 million recognized during the year ended December 31, 2023, which was primarily a result of the sale of the South Carolina Facility.
To date, we have primarily relied on debt and equity financing to fund our operations, including meeting ongoing working capital needs. Our management took certain actions during 2023 and during the first quarter of 2024 to improve the Company's liquidity.
