The costs of completing unfinished US nuclear power plants

There has been considerable debate in the USA over the relative costs of completing those nuclear generating units currently under construction. What are the regional costs associated with completing nuclear units and are there cheaper alternatives? A cost-benefit analysis is performed to assess the costs of completing unfinished nuclear capacity. We find that in most regions of the USA finishing the units is not the least-cost supply alternative. In fact in many regions, there will be no demand for the power before the year 2000. State regulators should take these estimates into account when determining the fate of individual units.
