DBS Group Holdings, Southeast Asia’s biggest bank, set up a project finance team to tap demand from companies and governments seeking to invest in infrastructure in Asia including power plants, roads and ports.

Lim Wee Seng will lead the team and report to Amos Tan, managing director of energy, chemicals and infrastructure at the institutional banking group, Singapore-based DBS said a statement today.

Infrastructure investment in Asia may be an estimated US$750 billion ($1 trillion) a year from 2010 to 2020, said DBS, citing figures from the Asian Development Bank. India and Indonesia are expected to invest heavily in power generation, DBS said.

Among recent project finance transactions, DBS underwrote $2.25 billion of debt that YTL Power International Bhd. used to fund its acquisition of power generator PowerSeraya from Temasek Holdings in 2009.
