A practical example of the benefits, profits and costs of an installation.

We are placing at the disposition of our readers the draft of a study for the installation of a generating unit here in Brazil which includes a cost / income table where certain values can be substituted to adjust projections to specific conditions. The fact that a CARE unit can generate in excess of 90% of the installed generating capacity, has practically no costs related to environmental questions and can be operated by satellite makes the technology exceptionally profitable.


Taking care of turbines

E-mail Print PDF

A new technology developed by Brazilian company CARE Electric utilises river !ows and allows for installation in practically any location, regardless of river width, depth and current

AUSTRIAN inventor Johann Hoffman has combined forces with Brazilian company CARE Electric to design a turbine system to capture energy from the natural !ow of rivers; eliminating the need for dams, reservoirs and !ooding of land. In acknowledgement of their work, CARE was one of 26 companies to be named as 2010 Tech Pioneers by the World Economic Forum.

The modular designed concept involves suspending turbines across the river and it is possible to place units successively downstream. The only real restriction or guideline is that each unit must be placed at a suf"cient distance from the proceeding unit, allowing the river which was highly oxygenated by the turbine blades, to return to its natural state. Models can be designed to be adapted according to the size and !ow of a river. The generating capacity is directly dependent on the volume of water !ow and river conditions. The volume of energy to be installed is currently a multiple of 167kWh which is the installed capacity of the slow speed rotation generator available. Larger capacity generators are being developed.


Irrigation For Profits

E-mail Print PDF

The research and planning for improved profitability and more efficient production based on efficient and low cost irrigation is one of the prime objectives of modern agricultural producers. The CARE technology for generating electricity is an option that should be considered. It can be installed by farmers' associations, cooperatives, individual producers and farming communities.
The purpose of this communication is to bring to the attention of interested parties the CARE technology recognized as a Technology Pioneer by WEF Davos 2010. It is an efficient  low cost and ecologically friendly energy generating technology.
The source of power and the cost of generation influences the marketing and cost of agricultural products throughout the world because it includes environment and conservation considerations, and consequently the formation of product value. An example is the international meat market where many countries are beginning to raise economic barriers to agricultural products produced with disregard for the environment.
The cost of energy is one of the most significant expenditures in any agricultural activity, either for irrigation or raising livestock. The cost for each producer is the parameter that should help determine whether irrigation is economically applicable. The CARE technology meets the requirements of modern agriculture.

An integral pat of the structure are concrete flanges installed at the river banks at the extremities of a unite. In some cases, depending on the width of the river, intermediate flanges are placed in accordance with the width of the turbines to be installed. Hydraulic lifts are installed on the upper part of each flange that supporting the weight of one to three turbines in their operating position or when necessary raise them totally or partially out of the river liberating its flow or current.

Considering that the units will be manufactured in sections this facilitates  the transportation of a unit to the point where it will be assembled. This not only  reduces drastically the time necessary from the moment of approval of a generating site to  the start up hereby favorably  influencing the capital return factor as it also Makes smaller units economically feasible.


Installed Potential

The CARE-ELECTRIC Turbines are projected in sections permitting various combinations for installations which in turn  provides for different generating potentials. The capacity to generate using the CARE  technology is directly related to the flow per second  in cubic meters  as well as the width and depth of the location selected.


Introduction to a Technical evaluation of the CARE technology

E-mail Print PDF

The following is an introduction to a Technical evaluation of the CARE technology by the Federal Center of Technological Education of Minas Gerais Brazil

Professor José Raimundo da Luz wrote as an introduction  to the Universities evaluation report:

“The CARE turbine is the most important discovery for the generation of electric energy with no pollution for the immediate future. We believe that the CARE generation technology provides the opportunity for profound social and economic changes.”

“In developed countries it can generate energy to produce hydrogen fuel while in developing countries it can bring energy to remote and poor areas. In both cases it is a potential generator of millions of jobs direct and indirect which can change the world economy.”

The difference is the reality between installed capacity and energy generated

Before presenting the cost estimates of a CARE generator with a 1Mw capacity it is important that the reader has a clear understanding of the meaning of Installed Capacity and Effective Generation or energy generated at the installation

A hydraulic electric energy generating unit has what is called installed capacity which is registered on the specification plate of each installed generator. The sum of the values determines the total installed capacity of a unit in megawatts. For example if a unit houses three 1Mw generators the installed capacity is therefore 3Mwh. This is the number applied with reference to the capacity of the unit. This creates a distortion in projection, costs and profit. The value that should be employed when measuring the capacity and cost of a hydraulic energy generating unit is the volume of energy effectively produced or generated.

An Example:

In Brazil in order to calculate the value of the installed capacity for a 3000 kWh unit or 3 MWH the cost per MW is estimated at R$5.500.000,00 ( US$ 2.972.973,00) per MW installed or a total of R$16.500.000,00 (US$8.918.919,00) therefore each kWh costs R$5.500,00 or US$ 2,703,00.

However considering that the effective generating capacity is 60% of installed capacity which is average for such installations , it is necessary to multiply the 3000 kWh of installed capacity by 0.60 to determine real generation capacity 1800 kWh but the investment was for 3000 kWh.

When the total value of the installation of US$ 8.9MM is divided by the power actually generated, 1800 kWh, cost is US$4.955,00 per kWh

The CARE technology considers that the generated energy is practically equivalent to the installed capacity. However conservatively, 90% is used for comparison.

The turbines were designed so the rotor output is always equal to or superior to the maximum rotation of the generator and also its length allows the greater volume of the river flow to pressure the blades attached to its perimeter there by providing torque superior to that necessary for maximum power generation. Therefore the excess of hydraulic power keeps the generators at full power output or the installed rate even if there is a reduction of the water flow. The conclusion is that the potential power installed is what the generators will produce .

Another important factor is the mechanical power lost is minimum because the generator is connected directly to the turbine axel. For these and other reasons the potential and real power generation of a CARE unit are practically equal and therefore influences the cost of the kW installed resulting in a much more favorable cost / return relation.

Other important factors that should be considered in determining the economic feasibility of the system are:

  1. Installations can be totally controlled by satellite eliminating on site staff.
  2. The time necessary between preparing the project, manufacture of the parts , assembling at the site and

start up depending on the potential desired is approximately 12 months. This time frame will be

substantially reduced when the manufacturing process is placed on assembly line technology.

  1. No land is flooded therefore there are no compensation costs or cost of relocation local wild life.
  2. The river flow and the river bed remain unaltered.
  3. Fences are not installed therefore the material contained in a rivers bed continues to flow leaving down river conditions constant and unchanged and ecologically sound.
  4. Units can be located successively down stream in the same river which naturally increases the generating potential in a specific area or down stream from an existing dam .
  5. Units can be placed close to areas of consumption farms, factories , resorts , mining operations etc.

For a budget to reflect its objective which is a close approximation of the real costs. In the case of CARE where the environment is not destroyed or changed the natural conditions at the potential site at the point of generation is a factor that will influence the selection of the installation.

In order to properly and accurately develop a project it is essential that information with respect to flow conditions at high and low water are available, the height of the river banks depth of the river and other pertinent information are available to develop a secure budget or cost projection and to properly project the profit potential.

In spit of the fact that the units are manufactured in sections it is important to always keep in mind that each site requires

at the site selected.

a specific project. This because the size of the turbines will vary according the flow in m3/sec. and the width of the river

t is important to bear in mind that each project is distinct having specific characteristics’ in spit of the fact that the system is modular This confirms that the size of the turbines has a direct influence on the energy generated as well as the return on the investment.

The fact that it is possible to install units successively down river contributes to lowering cost of manufacturing as well as allotting installation cost to various units. Also with respect to distribution costs if such is a factor to be considered the ability to place units close to consumption is also a favorable factor.

As part of the cost projections that follow a 10% leeway has been adopted because the costs that are shown under Civil Construction and Annual Costs are estimated. All other items were all budgeted the Brazilian or international market.

In order to properly evaluate the economic reality of the technology the reader should take two very important points into consideration

The first is the time factor: Depending on the local conditions at the site of installation of a generator and the desired potential it is estimated that a 1000kWh unit from the moment the site is approved will take approximately six to eight months especially with the first units. Naturally this reflects very favorably on the capital return considerations especially when compared with hydro installation that take at least three years

The second point is that various units can be installed in the

same river area. Units must respect a distance that allows the water to return to its natural flow after being oxygenated as it passed thorough the turbine blades.

All local conditions must be confirmed and a visit to the potential site by CARE personnel is necessary. However accurate information with respect to high and low annual level in dry and wet seasons are the factors of prime importance


The cost projection that may be solicited demonstrates that the cost of a 1 MWH operating 350 days per year for 30 years .

The ideal river conditions for the installation of the example presented in the cost projection is an average flow of 50m3/sec. with a width of approximately 44 meters and river banks of up to 3 meters.

The cost projection confirms that value of the kWh installed varies in accordance with the total power installed. If the installed potential is greater in scale the cost of a kWh is less and if the if installed generation is lower the cost for kWh will be higher.

The cost projection sheet provides or permits the user to alter at has selection the percent of financing which automatically reflects in the final results.

The interest value found in section 13 of 0% corresponds to the capital necessary to place a unit in operation . This percentage can be altered . The total value of financing paid monthly , if any, is shown in cell 147

The resulting Profit X Cost relation at 0% financing is expressed on in cell 171 . This number can be interpreted to

mean that it reflects the gross income from generation less operating costs and working capital at total cost

Once the annalist has determined the values to be inserted into the white spaces the cost of kWh installed appears in (D72) and the MWH in (D73)

The values to be applied for working capital , contingencies, labor and contracted third parties should be determined by the investor . These values will vary from region to region and country to country.

Included in the costs for the first unit are the cost of the forms used to produce concrete parts however such parts can be charged to other installations .Such values are automatically if the number of installation is modified.

The presentation does not take into consideration such items as taxes, specific charges to energy generation because such cost depend on the geographic location of the unit as well as the business structure or organization to be employed
