Energi Terbarukan Pembangkit Listrik Tenaga Mikro Hidro di Solok Selatan

Summary

This video discusses the development of a micro-hydro power system designed to replace diesel generators used for powering residential areas. The project features a 40 kW micro-hydro system, utilizing water flow from a 300-meter pipeline and a 480,000-liter reservoir. The system is designed to operate 24/7, providing a more cost-effective and sustainable energy solution compared to diesel generators, which previously consumed about 42 liters of fuel per day. With the increasing cost of fuel, the micro-hydro system offers substantial savings, with the investment expected to break even in 24-36 months. The project demonstrates the potential of renewable energy solutions for off-grid communities.

Takeaways

• 😀 The micro-hydro system aims to replace diesel generators used for residential lighting in off-grid areas.
• 😀 The system is designed with a water reservoir, a dam, and a turbine to generate renewable energy from water flow.
• 😀 The current infrastructure includes a dam with a water capacity of 480,000 liters, an 8-meter wide, 2.5-meter high water source, and a 24-meter long reservoir.
• 😀 The micro-hydro system has an estimated return on investment (ROI) of 24-36 months, depending on fuel prices and energy consumption.
• 😀 The savings in diesel fuel are significant, as the cost of diesel has risen above IDR 15,000 per liter, making the micro-hydro more cost-effective.
• 😀 The micro-hydro system operates 24 hours a day, unlike the diesel generator, which runs for 7 hours a day.
• 😀 The system helps save up to 42 liters of diesel fuel daily, with a monthly savings of approximately IDR 14 million.
• 😀 During peak flow or overflow, excess water is directed to the river, ensuring the system doesn't get damaged or overused.
• 😀 The micro-hydro system uses a 3-phase turbine and operates with two main power sources: water flow and air pressure.
• 😀 The system has been operational despite dry and rainy seasons, with overflow management in place for high water levels.
• 😀 The total cost of the system, including both the turbine and civil infrastructure, is around IDR 460 million, with a 3-year payback period.

Q & A

What is the primary goal of the micro-hydro power system discussed in the transcript?

The primary goal is to replace diesel generators used for residential lighting with a more sustainable and cost-effective micro-hydro power system.

What is the capacity of the micro-hydro power system?

The micro-hydro power system has a capacity of 40 kW.

How does the micro-hydro system generate power for lighting?

The system uses water flow to generate pressure which is then harnessed by turbines to produce electricity for residential lighting.

What are the physical dimensions of the micro-hydro system’s water source and dam?

The water source has a height of 2.5 meters, and the pool is 24 meters long, with a dam holding approximately 480,000 liters of water.

How long is the water channel that feeds the micro-hydro system?

The water channel is about 300 meters long.

What happens to excess water that exceeds the system's capacity?

Excess water is directed through an overflow system to prevent it from impacting the operation of the micro-hydro system.

How does the micro-hydro system compare to diesel generators in terms of fuel consumption?

The micro-hydro system operates 24 hours a day and significantly reduces fuel consumption compared to diesel generators, which consumed 42 liters of diesel per day for 7 hours of operation.

What is the expected payback period for the micro-hydro power system?

The expected payback period for the micro-hydro power system is around 24 months, given current fuel prices.

What is the total investment required for the micro-hydro project?

The total investment for the micro-hydro project, including both turbine and civil works, is estimated at 460 million IDR.

How does the micro-hydro system handle variations in water availability, such as during dry seasons or floods?

The system is designed with mechanisms such as overflow drainage to handle excess water during floods, and it operates effectively even during dry seasons due to the robust water flow management.
