Wind Energy Holding (WEH), a leading wind farm developer, has appointed Emma Collins as sole chief executive after the resignation of fugitive billionaire Nopporn Suppipat.
The appointment takes effect immediately, the company said in a release.
Ms Collins, who was the company's co-chief executive, will sit on WEH's board of directors.
Before joining WEH earlier this year, Ms Collins was managing partner at Platina Energy Partners LLP and had held senior posts at Vestas A/S, NED Micron Rotors and Taylor Woodrow.
WEH is Thailand's biggest wind energy firm. Its two wind farms in Nakhon Ratchasima, with a combined capacity of 107 megawatts, feed energy to the power grid.
The company is also developing seven wind farm projects with a total generating capacity of 650 MW, which would make WEH the biggest wind power firm in the region in terms of contracts.
WEH said Mr Nopporn had resigned from the board of directors.
"The allegations against Mr Nopporn are his own personal matter and are in no way linked to WEH," the company said.
Mr Nopporn, the youngest billionaire to make the Forbes list of the country's richest people this year, has been on the run after police issued an arrest warrant for allegedly hiring former Central Investigation Bureau chief Pongpat Chayapan's network to force his creditor, Bandit Chotwitthayakul, to slash his debt from 120 million baht to 20 million.
