The New Zealand Superannuation Fund has pumped another US$50 million into an American clean energy company which helps provide power for Google, Walmart and Coca-Cola.
The $25 billion fund, which was set up in 2003 to help pre-fund the retirement costs of the baby boomer generation, initially invested US$50 million
into Bloom Energy in May 2013.
Matt Whineray, general manager investments for the fund, said its second investment would support the growth of the business.
He said the fund had invested in the company to help it take advantage of increasing demand for energy globally.
"Alongside our traditional energy investments we're actively diversifying into alternative and non-conventional energy."
