| Projected Costs of Fusion Energy |

| Power production
technologies based on fusion belong to the class with low "external"
costs, comparable with solar and wind based technologies. In
the last decade, several models have been developed to estimate
the cost of power produced by fusion-based technology. The direct
costs of energy production, the breakup of which is shown in
Figure 1, can be estimated fairly accurately and is expected
to be in the range of 45-90 milliUS$/kWh (1995 values), with
a most probable value of 63milliUS$/kWh (about Rs.3.00/kWh)
which is very comparable to today's prices. Moreover, the collective
construction and operation experience is expected to lead to
considerable cost reduction due to accumulated learning processes.
Thus as more and more reactors are built, the resulting energy
cost is expected to reduce. The projected cost reduction with
time after commercial exploitation starts is shown in Figure
