Annex 8. Investment Estimate
The investment necessary for the construction of a power plant,
together with itsproduction, are a determining factor in the
evaluation of the profitability of ahydroelectric power plant.
This annex seeks to justify the base prices used, as well as the
quantification thatwas carried out for the different elements that
make up the development.
The objective of this study is not to serve as a technical
document for construction,
nor is the need to generate detailed measurements or an
exhaustive budgetconsidered at this time. Additionally, it is most
probable that the designs included inthis document will be modified
during the preparation of the construction project,with the
objective of adapting it to the geological studies that are carried
out, to thedetailed topography and to other conditions that may
arise.
Therefore, a valuation of the construction is sought without
entering into excessivedetail, leaving out the subdivision and
unitary parts of the project. That is to say,this report seeks to
obtain a representative valuation of the principal parts of
theproject for its posterior analysis and interpretation.
1. Price Justification
A small database of basic prices has been generated, which
were obtained througha consultation carried out between different
suppliers and developers in theRepublic of rpska between !ebruary
and "ay #$$%.
To determine the basic prices for the &ivil 'orks, such as
excavation in any ty"e o# terrain$ cleanin% and clearin% o#
terrain$#orwork$ rein#orced concrete$ industrial
&uildin%$ creation o# access roads$ the prices were
taken from local companies,adopting an average price of the
available range.
!or another group of items, sufficient information was not
obtained for a local offer,thus current prices in pain were used to
calculate the budget. These items arerock#ill f or t'e

2. Measurement and Valuation
To allow for the application of the justified prices, the
measurement of different unitsthat will be incorporated into the
construction has been carried out. To thesemeasurements, the
previously justified unitary prices have been applied, obtaining
avaluation for each of the chapters.
4n this document, the descriptions by chapter for the principal
units of constructionare presented( intake, piping, surge tank,
machine house, access roads, equipmentand electric
installation.
Thus, for each chapter the general construction units are
described( earthmovement, concrete, brickwork, roads, etc. These
parts are listed by described listprice and the measurements of the
current project.
This information is presented in the final report.
3. Generation equiment and electrical installation
The economic valuation of the electro5mechanic elements, of
generation and therest of the electrical installation are obtained
using specific consultations withuropean manufacturers with varied
experience. The installation costs for this typeof equipment can be
considered similar in all of urope.
The costs appear in the final table.
!. En"ineerin"# $inancial and %errain &osts
Apart from the strict construction costs, other costs
exist that form a part of the totalinvestment. These correspond to
the concept grouped generically bellow the title67thers8, which
includes the previous geological and geotechnical
campaigns,detailed topographic information and other specific
studies that can be necessary. As well, the engineering work
for the preparation of the construction is included,which is based
on the data obtained in previous studies, the technical
managementof the administrative processing, the payment of taxes if
they were any, thepurchase of terrains, the bidding and contracting
of the works and equipment, the
direction and coordination of the works and finally the start up
of the installation.

7ther costs that could be found within the concept of financial,
includes the costsdependent on the type of financing, which include
the inserted interested and thecommissions from the opening of
credits. These financial costs are presented in theeconomic study,
but are not considered as a part of the investment, given that
afinancial scenario with its own funds will imply the inexistence
of these factors.
Thus, we assume that the costs called 6others8, will make up 2'(
