Private equity firm Terra Firma is considering selling its 68.6% stake in Infinis Energy, a renewable energy firm founded by British financier Guy Hands.
Terra Firma invested in the company more than a decade ago and floated it in November.
The company was quoted by the Financial Times (FT) as saying: "Given that Terra Firma owns a significant majority stake, it believes there is merit to exploring potential interest in the stake as a whole alongside other options, including the potential for market sell downs."
Terra Firma invested £51m in Infinis in 2003 and has a stake worth approximately £450m, the FT reported.
Earlier this month, Guys Hands criticised the UK’s energy policy, claiming it was against ‘onshore wind power’.
Hands posted on Terra Firma’s website: "The cost of electricity generated by onshore wind has been falling fast and is now close to parity with gas.
"The government itself has confirmed that onshore wind generation will be the cheapest form of new-build electricity within a few years.
"But rather than support this success, the onshore wind industry finds itself under attack from government.
"We desperately need an energy policy based on facts, not populism and wishful thinking. A good start would be for government to treat onshore wind fairly, through a policy that doesn’t bow down to nimbyism but which stands up to it."
