Preliminary site survey is a short visit to verify the findings from the Desk Study. Head measurement and spot flow measurement should be taken as a basis of further hydrology analisys. Preliminary data must be collected as much as possible, and other tecnical and non technical issues must be recognised during the survey.

While in Pre-feasibility phase we are to compare several scheme or layout options such as: ease of construction, costs, operational aspects, environmental impact, other aspects;

In Feasibility study phase, the most attractive option has been chosen, and we are focusing the study of the scheme, in result that it would allows final decision for developer wheter to go on with construction or not

To achieve a 5% precission in the Cost Estimation of a Feasibility Study, a Detailed Engineering Design together with Bill of Quatity is a necessary process to be done. Detailed Engineering Design will include detailed layout, as detail as 1m resolution, structure drawings (Weir, Canal, Forebay, Powerhouse, etc), Mechanical & Electrical layout in the Powerhouse, as well as Transmission Line scheme. A proper Detailed Engineering Design and accurate Bill of Quantity will minimize mis-calculation and avoid such as over-budget during the development of the project

Financial Analysis

The most basic but comprehensive training about mini and microhydro power technology. The training shows the benefit and as well the requirements of hydro power technology implementation

The training is addressed for consultants and practisioners, the goal is to be able to identify and explore potential hydro power sites. The training gives an overview of site identification tools and basic setup of all elements like; field measurement (head & flow) technics, catchment area calculation, environment impact analysis, load analysis, simple financial analysis

Operating a micro hydropower plant requires certain knowledge and skills for operator, even more critical when dealing with mini scale hydropower plant. This training provides the knowledge to operate, maintain, and manage such a plant, both in theory and practical skills

program such as building micro hydropower curriculum for vocational school require extensive effort to identify the available resources, building capacity such as Training for Trainier, preparation teaching modules, providing equipment for simulation, these steps require carefull program design and management

pt entec Indonesia has carried out implementation od programs for village electrification such as technical support unit for PNPM Mandiri program and Micro Hydro Power Project during 2000-2006. We understand the complexity of such program and how to overcome the problems

sustainable hydropower plants in the village can not be achieved by solely installation of equipment The operator and management team has the burdon to keep the plants in operation. By conducting regular monitoring and evaluation of the hydropower plants, we could extend the life expectance of such plants

Crossflow probably the most suitable turbine type for elctrification program in Indonesia. Designed for mid head sites and very adaptable for various flow conditions, crossflow has been fully manufactured by the local wokshops. The quality and reliablility is proven even for export

Pelton turbine harnesses the high head potential. The pure impuls turbine system is very simple yet highly efficient. Pelton turbine is also known for its ability to accommodate the wide range flow fluctuation, even as low as 10%

As a part of hydropower plant component, a good and reliable trash rack system is very important to keep the plant operational and reduce the plant down time due to trash

Control system is the brain in a power plant. Different level of technology is developed for different focus targets. ELC for example is excellent in a remote, isolated, village electrification sites, while a more complicated minihydro plant requires micro controller based flow control system

Test bed educational systems are available in various combination and purposes, suitable for product showcase, teaching aids, research and development, and other specific purpose.

The system consists of water pump, hydro turbine (crossflow, propller, or pelton), DC generator, Panel display, metering equipment (analog or digital), and load models. Design output power is 40 Watt DC.

Main Valve, Expansion Joints, Automatic Closing Device, Drainage system, are example of other hydro related equipment

This license gives the Turbine Manufacturer the right to produce the entec T15-300 crossflow turbine. A proven standard turbine for up to 150 kW, suitable for micro hydropower electrification program

Currently the largest of the entec T15 crossflow design family. The T15-500 crossflow design can be used for micro and mini hydropower project for up to 300kW

We offer a turn key project for rehabilitation of existing power plants. The process will start with assessment of the current condition of the plant, and preparing Feasibility Study for the Owner of the plant. refer to the Salido Kecil MHP for our example project

We also offer turn key project for new power plants. Our involvement includes Preliminary Site Survey, Pre and Feasibility Study, Detailed Engineering Design, and Supervision during Construction. When requested we con also offer Operation and Management Training
