History of Tiwi-MakBan Geothermal power plant- Philippines
The Tiwi-MakBan geothermal power plant in the Philippines has a long and interesting history. The first geothermal exploration in the area was carried out by the Philippine National Oil Company (PNOC) in the early 1970s. In 1976, the Tiwi geothermal power plant, the first geothermal power plant in the country, was commissioned with an initial capacity of 49.4 MW.
In 1979, the MakBan geothermal power plant was commissioned, and it became the largest geothermal power plant in the world at that time, with an initial capacity of 458 MW. The MakBan plant was later expanded to its current capacity of 1,100 MW, making it one of the largest geothermal power plants in the world.
The Tiwi-MakBan geothermal power plant was initially owned and operated by PNOC, which was later privatized in 2007. The Energy Development Corporation (EDC), a subsidiary of the Philippine conglomerate First Gen Corporation, acquired the Tiwi-MakBan facilities for $930 million.
Since EDC took over the operation of the Tiwi-MakBan geothermal power plant, the company has invested heavily in the facilities, including the installation of new equipment and the implementation of various upgrades and maintenance programs. These efforts have helped to ensure that the plant operates efficiently and reliably, providing clean and renewable energy to the Luzon grid, which serves the country's most populated island.
The Tiwi-MakBan geothermal power plant has played a significant role in the development of geothermal energy in the Philippines and has helped to position the country as a leader in the use of this renewable energy source.
Tiwi-MakBan Geothermal power plant- Philippines Technology
The Tiwi-MakBan geothermal power plant in the Philippines uses advanced geothermal technology to generate electricity from the natural steam produced by the geothermal reservoirs in the area.
Here are some of the technologies and processes used in the plant:
Geothermal wells: The plant has numerous geothermal wells that tap into the natural steam and hot water produced by the geothermal reservoirs located deep underground. These wells are drilled using advanced drilling technology and are lined with steel casing to prevent the wellbore from collapsing.
Steam turbines: The natural steam produced by the geothermal reservoirs is used to power steam turbines, which are connected to electric generators that produce electricity. The Tiwi-MakBan plant uses both single-stage and double-stage steam turbines.
Cooling systems: After the steam has been used to power the turbines, it is condensed back into water using a cooling system. The plant uses various cooling systems, including air-cooled condensers and water-cooled condensers, to ensure that the steam is efficiently condensed.
Reinjection systems: Once the steam has been condensed, the resulting hot water is pumped back into the geothermal reservoirs through reinjection systems. This process helps to maintain the pressure and temperature of the reservoirs, ensuring a sustainable source of geothermal energy.
Monitoring and control systems: The Tiwi-MakBan geothermal power plant is equipped with advanced monitoring and control systems that enable operators to monitor the performance of the plant and adjust the processes as needed to optimize efficiency and reliability.
The Tiwi-MakBan geothermal power plant uses a combination of advanced drilling, turbine, and cooling technologies to harness the natural energy produced by the geothermal reservoirs in the area and generate clean and renewable electricity for the Philippines.
