GE, Swiss private equity firm Partners Group Holding AG (PGHN.S), Canadian pension fund OPTrust and UK-based Renewable Energy Systems Ltd said they will fund the 240-megawatt Ararat windfarm, three days after the government passed a law securing future subsidies for renewable energy. Windfarms are Australia’s No. 2 renewable energy source, behind hydropower but ahead of solar, providing a quarter of the country’s clean energy and 4 percent of its total energy demand. Under Australian law, the RET must be agreed by both the coalition government and the Labor opposition.
