Exergy participated on April 27th at the inauguration ceremony of EDC’s first geothermal brine recovery power plant held in Brgy. Ilomavis in Kidapawan City, Cotabato province.
The new ORC unit was synchronized to the Mindanao electricity grid on March 12 then passed compliance testing by system operator National Grid Corporation of the Philippines on March 25 and it is now delivering 3.6 MW of carbon-free electricity to the grid.
The Exergy ORC unit was designed and supplied in less than 12 months complying with strict deadlines.
The ORC cycle operates by recovering the heat from the geothermal brine available from EDC’s 103-MW Mindanao 1 & 2 existing steam power plants and converts it into electricity through the Radial Outflow Turbine. Heat from the brine is then re-injected back to the reservoir.
The new ORC installation will enhance the efficiency and productivity of the existing geothermal field without any additional environmental impact. Aside from providing clean and reliable power to the Mindanao grid, the project will also avoid around 25,000 tons of equivalent carbon dioxide yearly using geothermal energy.
