Four different stellarator configurations (a Compact Torsatron, a new modular torsatron, Helias, and a new Modular Helias-like Heliac) were analyzed as fusion power plants and compared with the second-stability ARIES-IV tokamak. The device and plasma parameters were determined by minimizing the projected cost of electricity subject to various constraints. The stellarators were competitive with ARIES-IV for a range of assumptions on confinement models, alpha-particle losses, and beta. 1-D power balance equations were solved for both Lackner-Gottardi confinement scaling with an assumed n{sub e}(r) and for helical-ripple-induced transport with both assumed and calculated forms for n{sub e}(r) and E{sub r}(r).
