Malitbog Geothermal power plant- Philippines
Malitbog Geothermal Power Plant is a geothermal power plant located in Barangay Tongonan, Kananga, Leyte, Philippines.
It is operated by the Energy Development Corporation (EDC), the largest geothermal energy producer in the country. The power plant was commissioned in 1996 and has an installed capacity of 232.5 MW, making it one of the largest geothermal power plants in the Philippines.
The Malitbog Geothermal Power Plant uses steam produced by the natural heat of the earth to generate electricity. The plant has four units, each with a capacity of 58.125 MW. The steam is extracted from deep underground through production wells and is then used to drive turbines that generate electricity.
The power generated by the Malitbog Geothermal Power Plant is transmitted to the Luzon, Visayas, and Mindanao grids, providing a significant portion of the electricity needs of the Philippines. Geothermal energy is a clean and renewable source of energy that does not produce greenhouse gas emissions, making it an important contributor to the country's efforts to reduce carbon emissions and combat climate change.
History of Malitbog Geothermal power plant- Philippines, Overview
The history of the Malitbog Geothermal Power Plant dates back to the 1970s, when geothermal exploration began in the region. The Tongonan geothermal field, where the plant is located, was discovered in 1977 by the Philippine National Oil Company (PNOC).
In 1983, PNOC entered into a joint venture agreement with the Philippine Geothermal, Inc. (PGI) and the Japan National Oil Corporation (JNOC) to develop the Tongonan geothermal field. The joint venture company, called the Leyte Geothermal Production Field (LGPF), began construction of the Malitbog Geothermal Power Plant in 1992.
The power plant was commissioned in 1996, with the first two units going online in April and June of that year. The third unit was commissioned in September 1996, and the fourth and final unit was completed in December 1996.
In 2007, the LGPF was acquired by the Energy Development Corporation (EDC), which became the new operator of the Malitbog Geothermal Power Plant. Since then, the plant has undergone several upgrades and improvements to increase its efficiency and capacity.
Today, the Malitbog Geothermal Power Plant is one of the largest geothermal power plants in the Philippines, providing a significant portion of the country's electricity needs. The plant is an important contributor to the Philippines' efforts to promote clean and renewable energy and reduce its dependence on fossil fuels.
Malitbog Geothermal power plant- Philippines, Technology
The Malitbog Geothermal Power Plant uses the binary cycle technology to generate electricity from the natural heat of the earth. This technology is ideal for low-temperature geothermal resources like the Tongonan geothermal field, which has a temperature range of 250°C to 280°C.
The binary cycle technology works by using a heat exchanger to transfer heat from the geothermal fluid to a working fluid, typically an organic Rankine cycle (ORC) fluid. The working fluid has a lower boiling point than water, so it vaporizes at a lower temperature, which allows it to generate electricity at lower temperatures.
The steam from the geothermal fluid is separated from the hot water and is used to vaporize the working fluid in a heat exchanger. The vaporized working fluid then drives a turbine, which generates electricity. The vaporized working fluid is then cooled and condensed back into a liquid, which is pumped back to the heat exchanger to repeat the process.
The binary cycle technology has several advantages over other geothermal technologies. It is more efficient at low-temperature resources, which makes it suitable for use in areas with low to moderate geothermal potential. It also has a low environmental impact, as it does not release any emissions or pollutants.
The Malitbog Geothermal Power Plant has four units, each with a capacity of 58.125 MW, for a total installed capacity of 232.5 MW. The plant uses 29 production wells to extract steam from the geothermal reservoir, and the steam is transported to the power plant through a network of pipelines. The power generated by the plant is transmitted to the grid through a substation located near the power plant.
Malitbog Geothermal power plant- Philippines, environment impact
The Malitbog Geothermal Power Plant has a relatively low environmental impact compared to other conventional power generation technologies. Geothermal energy is a clean and renewable energy source that does not produce any greenhouse gas emissions or air pollutants during the electricity generation process. The use of geothermal energy for power generation can help to reduce the Philippines' dependence on fossil fuels and contribute to its efforts to reduce carbon emissions and combat climate change.
However, the development and operation of geothermal power plants can have some environmental impacts, particularly during the exploration and construction phases.
Some of the potential environmental impacts of geothermal power plants include:
Land use: Geothermal power plants require a significant amount of land for drilling wells, constructing power plants, and laying pipelines. This can result in land degradation, habitat loss, and fragmentation, which can affect local biodiversity.
Water use: Geothermal power plants require large amounts of water for cooling and generating steam. This can affect local water resources, particularly in areas where water is scarce.
Subsidence: The extraction of steam from the geothermal reservoir can cause subsidence, which can affect the stability of the ground and cause damage to infrastructure.
Noise and visual impacts: The construction and operation of geothermal power plants can generate noise and visual impacts that can affect local communities and wildlife.
Operator
The Energy Development Corporation (EDC), the operator of the Malitbog Geothermal Power Plant, has implemented several measures to minimize the environmental impact of its operations.
These measures include:
Replanting and reforestation: EDC has implemented a reforestation program in the Tongonan geothermal field to restore the natural vegetation and protect local biodiversity.
Water conservation: EDC has implemented water conservation measures, including the use of recycled water for cooling and the implementation of water recycling systems.
Community engagement: EDC engages with local communities to understand their concerns and implement measures to mitigate the impact of its operations on local communities.
While geothermal power plants have some environmental impacts, their low emissions and renewable nature make them a favorable option compared to conventional power generation technologies.
