Swedish-Swiss multinational corporation ABB has secured a retrofit deal from the Philippines-based Energy Development Corporation (EDC), one of the world’s largest vertically integrated geothermal firms, to upgrade six geothermal units of two power plants totalling 200 MW, in the Philippines. The geothermal plants Palinpinon 1 and 2 are located in Valencia. Under the deal, ABB will deliver a new control system integration solution for the plants and an area control centre facility. It will also provide performance calculation and cybersecurity solutions. The scope of work includes the conversion of a mechanical electrohydraulic governor into a digital version, and the replacement of the existing low pressure turbine hydraulic equipment with a new high pressure solution.
