the following discussions. The effect of the error in cost estimation will be discussed in the next section. In contrast to the traditional availability A(/j)-A(/f), the finite time availability tells how much work a system can supply in the transition from state i to state f during the interval r = t} - t, (2). where St is the total entropy production rate. The decrease in the availability repre7 sents the work to be extracted. The system in the present case corresponds to the investment and industry dedicated to SPS construction. The recent finding concerning availability (3) indicates the dissipated availability, - AA, is bounded by the square of L, the length of the shortest path from i to f, multiplied by e/z, i. e. where e is the mean relaxation time of the system and U is the internal energy in equilibrium as a function of multidimensional variable X. The relaxation time, e in our case, is the time required for SPS development. If we include the basic development, the time is a function of readiness of technology including the environmental impact assessment. As the time goes, e decreases to a limiting value as shown in Fig. 2. The expression in Eq. (2) is valid in the quasi-equilibrium case. Whereas in a
