Small Decentralized Hydropower Program National ... - Cd3wd.com

Segundo es m&s adecuado para el desarrollo de las
redes y subestaciones de 10s sistemas y el tercero por
el hecho de ser una aportacidn directa de1 mismo con-
sumidor, tiene psicologicamente un derecho a ser
retribuido con la misma instalacidn de servicio que
constituye algo tangible y personal.
De alli que coma conclusion sobre la posibilidad de
otra Fuente de Recursos Financieros, podemos
advertir que para un programa de mini-centrales y
de pequefio tamaiio, la contraparte local a ser
obtenida por metodos indirectos coma 10s arriba in-
dicados no parece ser suficiente, por lo que deberia
buscarse para este programa la maxima financiacion
externa tanto para el equipo, coma para las obras
civiles.
Para tener una idea de la magnitud de1 costo actual
de centrales de mediano tamtio vamos a detallar a
continuation las caracteristicas principales y costos
de1 equip0 y obras civiles de cinco cent&es que IN-
ECEL tiene en estudio preliminar, con grupos de
capacidades entre 2.500 y 400 kW.
Estos costos dan un valor por kW instalado de
US$1.192; 1.466; 1.920; 2.200 y 2.700 respectiva-
mente, lo que indica un fuerte encarecimiento de las
obras conforme disminuye la capacidad de la central,

Of the three funds mentioned above, it appears
that the first may be the only one applicable as
counterpart in mini and small powerplant con-
struction programs, since the second is more ap-
propriate for the development of grid systems
and substations, and the third, since it
represents a direct contribution from the con-
sumer, appears at least psychologically earmark-
ed for reinvestment in the installation of services
which constitute a tangible and personal benefit
for the consumer.
In conclusion, as regards the possibility of us-
ing another source of financial resources for a
mini and small powerplant construction program,
the local coun;erpart obtainable through indirect
methods such as those mentioned above does
not appear sufficient. For this reason, maximum
external financing should be sought for this pro-
gram both for equipment and for civil works.
To give an idea of the magnitude of current
costs of medium-sized powerplants, we detail
below (Figure 1) the main characteristics and
costs of equipment and civil works for five
powerplants that INECEI.. has under preliminary
consideration, with groups ranging in capacity
from 400 to 2,500 kW.
