HONG KONG — China’s State Power Investment Corporation agreed on Wednesday to buy Pacific Hydro, a renewable energy company, from the Australian pension fund IFM Investors for an undisclosed price.

Pacific Hydro has electric and wind facilities in Australia, Brazil and Chile, and it will be added to the Chinese company’s roster of assets in 35 countries. State Power, or SPIC, was formed from a merger of China Power Investment Corporation and State Nuclear Power Technology Corporation and has interests in logistics and coal power.

“The acquisition of Pacific Hydro will add a high quality global renewable development platform to SPIC,” Wang Binghua, the chairman of State Power, said in a news release.

Kyle Mangini, the global head of infrastructure at IFM Investors, said the fund had “invested heavily in growing the business over the last 10 years.”
