Introduction

In the midst of increased demand for electrical energy, there are major challenges related to the limited energy supply. The issue of global warming is increasingly encouraging the development of water resources as an effective solution to meet the needs of electrical energy in a sustainable manner. Indonesia, with extraordinary geological wealth and abundance of natural resources, has great potential to develop renewable energy. This article examines the use of pumped storage electricity as a support for the Lake Toba geopark infrastructure in Samosir Regency. The main focus of this study is to determine the right head and discharge to be applied at the study location and alternative design analysis in accordance with the potential of the area.

Renewable Energy Potential from Pumped Storage

Pumped Storage Hydropower (PSH) is a technology that has long been known in the management of renewable energy. This system operates by pumping water to a higher reservoir when demand for energy is low, and release it to produce electricity when demand increases. In the context of Lake Toba, the use of this system can provide an environmentally friendly solution to deal with the surge in electricity demand. The benefits of PSH technology are numerous, including its ability to provide a stable and reliable source of energy, as well as its potential to reduce greenhouse gas emissions and mitigate the impacts of climate change.

The results of the study analysis showed that the Pumped Storage Hydroelectric Power Plant (PLTA) at this location has the potential to be developed in the 200 meter head with a design discharge of 117.48 m³/s. This development is believed to be able to generate power of 2 x 150 MW, which produces annual energy production reaching 858,480,000 KWH. This figure is very significant and can be a stable energy source, as well as supporting activities around the Lake Toba Geopark. The development of PSH technology in Lake Toba can also create new economic opportunities and improve the livelihoods of local communities.

Benefits for Lake Toba Geopark Infrastructure

Lake Toba Geopark infrastructure that continues to develop requires reliable energy support to support various tourism activities and local economic development. With the development of Pumped Storage hydropower, not only energy needs are met, but can also reduce dependence on fossil energy sources that have a negative impact on the environment. The use of PSH technology can also help to reduce the environmental impacts of energy production, such as greenhouse gas emissions and water pollution.

In addition, the energy generated from this system can be used for various purposes in the surrounding area, such as lighting, waste management, and other public facilities. Thus, the use of Pumped Storage hydropower plant also has the potential to create new jobs and improve the economy of local communities. The development of PSH technology in Lake Toba can also contribute to the conservation of natural resources and the preservation of cultural heritage.

Environmental Analysis and Sustainability

The use of renewable energy such as pumped storage is also in line with global efforts to reduce greenhouse gas emissions and contribute to global warming. By utilizing the potential for optimal water resources, we can maintain environmental sustainability, preserve ecosystems, and reduce the impact of climate change. The development of PSH technology in Lake Toba can also help to mitigate the impacts of climate change, such as sea level rise and extreme weather events.

The successful development of the Pumped Storage hydropower plant also depends on a comprehensive feasibility study, including environmental impact analysis, which must be done to ensure that infrastructure development does not damage the Lake Toba ecosystem which is very important both ecologically and culturally. The environmental impact analysis should consider the potential impacts of the project on the local ecosystem, including the effects on water quality, wildlife habitats, and cultural heritage.

Conclusion

The construction of Pumped Storage Hydroelectric Power Plant in the Lake Toba Geopark area of Samosir Regency promises energy solutions that not only meet local needs but also make a positive contribution to the environment and the economy of the community. With the existing potential, this development can be a clear example of sustainable utilization of natural resources, supporting environmentally friendly infrastructure, and encouraging renewable energy-based economic growth. Through the right steps, we can create a greener and sustainable future for future generations. The development of PSH technology in Lake Toba can also serve as a model for other regions in Indonesia and around the world, demonstrating the potential of renewable energy to support sustainable development and mitigate the impacts of climate change.
