Criterios de Evaluacih y<br />

Seleccih de Proyectos<br />

Es necesario evaluar y seleccionar 10s proyectos a<br />

fin dc permitir el uso adecuado de 10s escasos recur-<br />

SOS econ6micos y financieros y de la capadidad de<br />

construcci6n, de suministro y de fabricaci6n local de<br />

equipos y materiales.<br />

La evaluaci6n y selecckin de proyectos permite<br />

obtener una lista priorizada de 10s mismos, que a su<br />

vez per-mite la programaci6n anual de proyectos, de<br />

presupuekos, y la obtencirjn de fondos, de aporte<br />

naciond y de pr&tamos externos y/o internos.<br />

Los criterios de evaluaci6n y selecci6n son de tres<br />

tipos:<br />

- Criterios tknicos<br />

- Criterios econ6micos<br />

- Criterios sociales.<br />

En &reas ruralrs, donde se espera desarrollar el<br />

<strong>Program</strong>a de Pequefias Centrales Hidroekkicas es<br />

muy difkil det.erminar parametros econ6micos y<br />

sociales, principalmente debido a la falta de<br />

estadisticas.<br />

A continuaci6n se dan algunos de 10s criterios a<br />

emplearse en una evaluaci6n preliminar:<br />

such a method due to the ex!ensive calculations<br />

involved if done manually.<br />

It is not advisable to take more than 20 years<br />

for the projections in view of the uncertainty of<br />

rural market development.<br />

Evaluation Criteria and Selection of Projects<br />

It is necessary to evaluate and select projects<br />

to allow for the most advantageous use of the<br />

scant economic and financial resources and<br />

local construction capability, availability of<br />

materials and equipment. TtI:Q evaluation and<br />

selection of projects will develop a prioritized list<br />

which, in turn, will permit the annual program-<br />

ming of projects, budgeting, allocation of funds,<br />

na?ional support and external and/or internal<br />

loans.<br />

The evaluation and selection crireria are of<br />

three kinds:<br />

- Technical<br />

- Economical<br />

- Social<br />

In the rural areas, where we hope to develop a<br />

small hydropower plant program, it is very dif-<br />

ficult ‘to determine economic and social<br />

parameters, mainly because of the lack of<br />

statistical data.<br />

The following are some of the criteria to be<br />

employed in a preliminary evaluation:<br />

1. Hydro resources and geological<br />

characteristics<br />

\Neight X1<br />

Scores vary in a scale from 1 to 10,<br />

depending on the hydraulic resources and<br />

the geology estimated by use of the na-<br />

tional and geological maps. The classifica-<br />

tion would be bad, fair, good and very good.<br />

If possible, it is preferable to consider data<br />

relative to the annual average flow of the<br />

rivers in the mini-region under study.<br />

2. Topography of the Hydraulic Resource<br />

Vveight X2<br />

Scores vary from 1 to 10 depending on<br />

the estimated slope and general<br />

topography of the potential site for the<br />

mini-hydropower p!ant. TG a steeper slope<br />
