Global Power Synergy Plc (GPSC), a power generation arm of national oil and gas conglomerate PTT Group, continues to expand its renewable energy business by spending US$500 million (16.3 billion baht) to acquire a 25% share in the Changfang and Xidao (CFXD) offshore wind farm projects in Taiwan. The move marks GPSC's first investment in an offshore wind project, which will allow the company to expand its expertise in advanced construction technology as well as innovative wind turbine technology. The share purchase agreement was signed online yesterday between GPSC-owned subsidiary, Global Renewable Synergy Co, and offshore wind farm developer Copenhagen Infrastructure Partners, which represents the Copenhagen Infrastructure II K/S (CI-II) and Copenhagen Infrastructure III K/S (CI-III) funds.
