The electric power industry in developing countries, as in the rest of the world, faces least-cost planning problems characterized by a range of supply-side and demand-side options, multiple conflicting objectives, and pervasive uncertainty. Two recent least-cost planning studies were sponsored by the World Bank and carried out by utilities in Hungary and Costa Rica. Although the circumstances in the two countries are very different, and the studies were carried out by different teams, they reached similar conclusions. First, both studies concluded that availability of capital was a key ingredient in developing least-cost plans. This conclusion is particularly important for developing countries since their capital requirements for power supply expansion are huge, thus indicating the need for seekin new ways of mobilizing financial resources and the adoption of policies to encourage more efficient production and end use of power. Second, both utilities were able to do thorough multi-objective and risk analyses. Third, both studies found that the multi-objective and risk analyses led to some conclusions which differed from those reached by traditional optimization, and included some surprises. In particular, the Hungarian analysis pointed to more gas turbine capacity than was previously envisaged, and found that electricity imports were an attractive option. Implementation of load management was also a winner, at least as a hedge. The Costa Rican analysis concluded that varying the power supply mix was not desireable: the utility should continue its reliance on hydro, with minor additions of thermal capacity, but eschewing baseload coal or heavy geothermal development, and with diesels preferred to gas turbines.
