Introduction
Renewable energy has become a major focus in the development of a sustainable global energy system. Among various green energy sources, hydropower remains the backbone of reliable power generation. With high efficiency and low carbon emission levels, hydropower continues to be a strategic choice in many countries, including Indonesia.
In the context of higher education, Telkom University’s Energy Systems Engineering undergraduate program is present as a pioneer in the development of energy research and technology, including the use of hydropower. This article will discuss why hydropower is still a reliable source of energy from a technical, environmental and economic perspective.
Advantages of Hydropower in Renewable Energy Systems
1. High Energy Efficiency
Hydropower is one of the most efficient energy sources, reaching 90% in some modern water turbine systems. Compare this to solar energy which only has an efficiency of around 20-25%, and wind which is around 30-45%.
2. Energy Supply Reliability
- Not dependent on weather like solar panels and wind turbines.
- Can be used as base load (main generator) or peak load (load balancer).
- Has a fast response in the grid system (within seconds) when load fluctuations occur.
3. Long Operating Life
Hydropower plants generally have an operational life of more than 50 years with regular maintenance, making them a stable long-term investment.
Hydropower’s Contribution to National Energy and Environment
1. Hydropower Potential in Indonesia
Indonesia has 75,000 MW of water energy potential, but only about 8% of it has been utilized. Some potential areas:
- Sumatra: 22,000 MW
- Kalimantan: 21,000 MW
- Papua: 23,000 MW
2. Environmentally Friendly
- Very low CO₂ emissions compared to coal-fired power plants.
- No direct air pollution.
- Provides additional benefits such as flood control and irrigation.
3. Regional Energy Independence
Some remote areas such as Papua and Kalimantan have begun to implement micro-hydro systems that help overcome the limitations of PLN electricity.
