Deep Fission, Inc. (NASDAQ:FISN) today announced a Master Energy Purchase Agreement with the Great Plains Development Authority (GPDA), a quasi-municipal entity that owns the Great Plains Industrial Park in Parsons, Kansas. It converts the parties’ December 2025 letter of intent into a definitive contract for a commercial project at the site of Deep Fission’s Department of Energy (DOE) pilot. The agreement binds Deep Fission to pursue the project and to supply power once licensed and operating, subject to the agreement’s terms and conditions. Under the agreement GPDA will purchase electricity generated and made available by Deep Fission to satisfy the electricity requirements of industrial park tenants, up to the contracted capacity, with no minimum purchase obligation. The agreement also permits GPDA to assign its purchase obligations to qualifying tenants.

The initial phase is anticipated to be 150 MW with a target date of commercial operation on September 30, 2028, and grow through later phases to a total of 2,000 MW pending further demand growth.
