SPARC is a high-magnetic-field tokamak which will utilize high-temperature superconductor (HTS) magnets. Its stated goal is to become the first tokamak to achieve energy gain. SPARC is not designed to generate electricity, rather it will be used as a stepping stone to the first ARC which is intended as an electricity producing fusion power plant.

SPARC is anticipated to begin operation in 2027.
