Mintz advised Quaise Energy, a leading developer of utility-scale superhot geothermal energy, in the initial close of its $134 million Series B financing. The proceeds will support construction of the world's first commercial superhot geothermal power plant in Central Oregon, as well as the continued development and commercialization of Quaise's proprietary millimeter wave drilling technology.

The round was led by Prelude Ventures and included participation from JERA Co., Inc., Idemitsu Kosan, and existing investors including Safar Partners. Founded as a spinout from the Massachusetts Institute of Technology (MIT), Quaise is working to commercialize superhot geothermal energy at utility scale. The Series B financing brings Quaise's total funding raised to date to $230 million.

Mintz is proud to serve as a trusted advisor to Quaise throughout its growth journey, from its previous $21 million Series A1 financing to its latest Series B round, supporting the company's commercialization efforts and continued leadership in the climate tech sector.

The Mintz deal team was led by Joshua Fox and included Alexander Civetta, Libby Decker, and Jacob Neumark.
