- On the 26th May 2016, Queensland Premier Annastacia Palaszczuk, announced in parliament that ERGON Energy has offered to purchase the ful output of the Mount Emerald wind farm under a power purchase agreement.

The agreement was signed by executives of ERGON Energy and Mount Emerald on the 27th May 2016.

This agreement includes the purchase of all of the electricity and green energy certificates produced by the wind farm through to the end of 2030. This is a major milestone for the project as the power purchase agreement provides the revenue stream which underpins the financial case for the project.

This site will be updated as the approval process continues.
