“…Previously it was given the criteria of several authors in which they establish the levelized cost of energy for ACC between 40 to 80 USD/MW. The results obtained in this work are located in this range [20][21][22][23].…”

A new project of investment developed in Cuba has 25 Biomass Power Plants (BPP) with potencies of 20 and 50 MW. The confirmed lack of water to be used in the condensers is an impediment for the project. The use of dry condensers may be a possible solution, however, the cost of the initial project and the reduction in useful power associated with its use is a limitation to consider. In order to define the feasibility of the use of ACC in these projects, a case study is carried out in which several selection criteria for investment alternatives are considered, with three other types of condensation technologies being evaluated with the objective of comparing costs of investment and operation, as well as the profits generated. The analyses were carried out for a horizon of 20 years, obtaining for the ACC uses, a pay off period of 7.6 and 8.4 years, for the facilities of 20 and 50 MW respectively. With the uses of the selection criteria for investment alternatives, was obtained that for facilities of 20 and 50 MW respectively, the Return Interest Rate (IRR) is 18.2 and 23,8 percent, the Net Present Value (NPV) (with 15% update rate) is equal to 1126.9 and 3024.0 MUSD, the cost of the life cycle is 10682.4 and 24406.1 MUSD, while, the levelized cost of electricity production is 0.062 and 0.071 USD/kWh, with a costbenefit ratio of 0.1 and 0.13. The results obtained confirm the feasibility of using ACC systems.

“…The Cuban capital (Havana) is considered in the present study as a fourth region, taking into account the conditions of very high population density that it presents. Figure 1 provides in detail the location of each of the provinces that make up the island of Cuba, in Table 1 the provinces that make up each region are detailed, while, in the Table 2 is given a summary of the demographics' distribution in Cuba for each region of study [4].…”

“…This generation volume constitutes approximately 24% of the country's energy needs. This project includes a total of 25 BPP linked to sugar processing plants (SPP), which will be in charge of supplying the bagasse used as fuel in the BPP, while BPP will supply the steam required by SPP's industrial process [4].…”

In the present times, the use of air cooled condenser (ACC) has become generalized where the installation of power plants is required and access to condensation water is difficult. At present it is known that performing the thermal evaluation of an ACC is a complex task, since the existing methods do not consider all the elements that directly influence the performance of the ACC. A very widespread method is that attributed to Kröger, however its use does not provide adequate results for high values of environmental temperature, which is a limitation to be applied in tropical countries like Cuba. This document provides an analysis method that includes the effect of environmental variables and that allows reasonable results to be obtained for high values of ambient temperature. The new proposal follows the logical sequence of the Kröger method, but considering a new procedure for the determination of the mean heat transfer coefficients and pressure drops, required for the thermal evaluation of ACC.
