Table 3.3. SSPS Development Programs* transfer of the SSPS. Unlike the other technology developments, these are likely to be required -- in part or entirety -- by other space programs. If the only "customer" for these systems were the SSPS, then the latter should bear the full burden of repaying their development; however, this is not expected to be the case. Figure 3.1 provides an economic comparison between a five thousand megawatt SSPS and terrestrial electric power generation systems providing equal capability. The x-axis (abscissa) contains average values for the cost of electric generation over the 30 year period (1995-2025) in mills/kwh. A range of future electric generation costs, estimated by U.C. Berkley for the
