An Economic Assessment of Space Solar Power as a Source of Electricity for Space-Based Activities

Oct 1, 2001 | Molly K. Macauley, James F. Davis


We develop a conceptual model of the economic value of space solar power (SSP) as a source of power to in-space activities, such as spacecraft and space stations. We offer several estimates of the value based on interviews and published data, discuss technological innovations that may compete with or be complementary to SSP, and consider alternative institutional arrangements for government and the private sector to provide SSP.
