AGL Energy Limited
(ASX:AGL) will mothball four generating units from its Torrens Island power station in Adelaide in 2017.
The energy provider has decided to take the units out of service based on the current market outlook.
AGL says the move is unlikely to impact South Australian power supply and will be reviewed if market conditions change materially.
The company has not outlined any job cuts but says it has informed employees about the decision and will now start talks about the consequences.
AGL Energy reported a net profit of $570 million in the 2014 financial year.
