Infigen in Australia
Infigen managing director Miles George said: "Infigen has been assessing various options to improve the capital structure of our business and unlock security holder value for quite some time. The outlook for our remaining Australian business is positive following the recent passage of the amended renewable energy target legislation in Australia that provides policy certainty."
Last month, the Australian parliament approved legislation to cut the Renewable Energy Target support scheme from 41TWh to 33TWh.
Infigen currently has a six project portfolio in Australia with an installed capacity of 556.6MW and approximately 1GW in the pipeline.
