  • On the 26th May 2016, Queensland Premier Annastacia Palaszczuk, announced in parliament that ERGON Energy has offered to purchase the full 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.
