A profit warning from Contact Energy will crimp earnings growth at its Australian majority owner, Origin Energy.
Origin says its underlying full year profit is now unlikely to be more than 20% higher than last year.
An earlier forecast predicted the profit would be between 20% - 25% higher.
Contact said on Tuesday that it expects to see its underlying earnings fall by as much as a third because of lower wholesale electricity prices.
Origin owns 51% of Contact.
