John Belizaire, CEO of Soluna Holdings, commented, “Adding Ancillary Services to Project Dorothy is a key milestone in our revenue diversification plan and adds another turn to our business flywheel.”

“Our model is to monetize our data centers in multiple ways to maximize our return on invested capital and deliver superior returns for our (project-level) investors. Ancillary Services expands our model to three drivers,” Belizaire continued.

It’s a win in three important ways: Grid Resilience, Revenue Diversification, and Wind Farm Energy Utilization.”
