Ausgrid, a state owned electricity infrastructure company, owns, maintains and operates the electrical distribution networks to 1.6 million customers in Sydney, Central Coast, Hunter Region and Newcastle areas of New South Wales. It was formed in 2011 from the previously state owned energy retailer/distributor, EnergyAustralia, when the retail division of the company, along with the EnergyAustralia brand, was sold by the NSW State Government.
The company is owned by the Government of New South Wales; and it has two shares, one each held by the Minister for Finance and Services (New South Wales) and the NSW Treasurer respectively.
Ausgrid inherited the naming rights sponsorship of Hunter Stadium from EnergyAustralia in March 2011. The stadium was known as Ausgrid Stadium until the contract expired at the end of 2011.
