Years ago I developed the software Decidix to do feasibility studies for companies in the electrical sector. The objective was to have a tool easy to use by people not skilled in financial mathematics techniques and to people without experience in technical questions which influence in the feasibility of the business, for example the fuel efficiency of a power plant. The focus is on projects of power generation with renewables (wind, small hydro, solar, biomass, and biodiesel), nonrenewable fuels (natural gas, coal, oil, nuclear) and transmission lines and distribution substations. People enjoyed it and I applied regular courses for hundreds of experts from power utilities, oil and gas companies and investors mainly in the renewable energy business field. The tool enable to do from “easy” things like calculating the cost of the energy produced in a power plant up to complex analysis involving trends scenarios and the prioritization of groups of investment projects of different natures.

I decided to make Decidix  available as free software . The code is complete and there are no functions blocked or hidden parts. Some instructions for the use are showed in the first screen of the software. As I never had time to do the Instructions Manual I made available in the site the file with part of the course I apply about the theme. For people with some knowledge in the concepts of technical economical assessment it will be possible to use the tool

Program of the course

ASSESSMENT OF THE FEASIBILITY OF ENERGY PROJECTS (generation, cogeneration and transmission and distribution)

Motivation: To assess the feasibility of power and energy projects is a task relatively easy when we have available all the technical and economic data. The problem is that sometimes technical people is not well familiarized with the financial mathematics technics and the economists are not well familiarized with certain technical aspects which can have big influence in the analysis

This applies to both the generation and cogeneration plants with conventional or renewable fuels for small to large hydroelectric plants and transmission and distribution. Each case is one case and the analysis shall consider things so diverse as:

(a) the relationship between the generation cost and prices for buying and selling the energy
(b) the demands and electrical and thermal energy consumption for cogeneration..
(c) legislation, trends in energy and fuel prices,
(d) non availability and environmental costs
( e ) the economic data , interests and many y other
(d) the power plant availability, tax of failures, efficiency of the plant,;

If you have a basic knowledge on the technical and economical concepts and join to this some good sense it is possible to do a quite good analysis of easy and even more complex problems.

In this course, the objective is to present such basic rules in a easy to understand way and to teach how to use the DECIDIX free software to assess the feasibility of different projects.  We show the concepts and many quite different test cases found in the real life. The course is focused in professionals from electrical power utilities, energy companies, equipment manufacturers, research centers, investors and others. The main topics covered are:

1) General view of business and projects in the electric and energy sector (purchase and sales of energy, auctions for grants in generation, transmission and distribution, legislation, programs of incentives, risks of the business and others)

2) Technical fundaments related to technologies for power plants, transmission and distribution installations and lines. This include renewable and nonrenewable energy (small to big hydro power plants, thermal generation, cogeneration, wind , solar, distributed generation, fuel cells);

3) Methodology for the technical - economic analysis of the feasibility of energy projects ( using the software DECIDIX)

4) Case studies

5) Advanced topics


During the installation a password will be requested.

The password is decidix2012 (type with lowercase letters)

Along the installation only one directory will be created. It is named c://sergiofeitoza. Inside it there will be the files
- Decidix.exe
- some xml files (the data base is herey): t_trend.xml , t_cds_Fluxo.xml ,
cds_sens.xml , t_cds_R1.xml , t_cdsEcon.xml , t_projetos.xml
- perfildec.mlp
- some other few files
- unis000.exe (the uninstall file)
This setup is around 2,6 MB. If you have problems with the installation please write me explaining the messages received and I will try to help you. In this case please inform the opeartional system of your computer.
For the use of the software itself unfortunately I cannot provide technical support. To uninstall Decidix you may use the uninstall file or even simply to delete the directory.
Note that all the directory will be deleted including the data base.
Please remember the following:
a) When you open the application you can set the language of the screens to English (default) or Spanish or Portuguese or French.
b) I never had time to prepare a Instructions Manual but at the downloadable file (in English only) there are some instructions which may help you to use Decidix. If you stop the mouse over the boxes in the screens there are also some hints / instructions but some of them are not yet translated.
c) As written in this version is complete and there is no function locked. Some functions and features request training to use.
I hope Decidix will be useful to you
