The AUD 2.3 billion ($1.56 billion) EnergyJoin mission, an interconnector between New South Wales and South Australia with a spur hyperlink in Victoria, has reached two main building milestones, together with the connection of the primary part of the Buronga substation within the southwest of New South Wales.
Grid operator Transgrid, which is delivering the New South Wales part of the mission, stated the primary 220 kV part of the brand new substation is now related to the present Buronga substation, permitting energy to move throughout the bag. spine of EnergyJoin.
Transgrid CEO Brett Redman stated the substation connection was an essential a part of the protected testing and commissioning course of forward of the inter-networking check, which will likely be carried out by the Australian Energy Market Operator (AEMO).
“We proceed to work on delivering this nation-critical mission that may give thousands and thousands of customers entry to extra dependable, clear, and reasonably priced power,” stated Redman. “EnergyJoin permits us to maneuver renewable power between New South Wales, South Australia, and Victoria the place and when it is wanted, serving to to make our power system safer.”
Transgrid stated that the Buronga substation is without doubt one of the largest and most refined substations within the southern hemisphere. It will embody 5 phase-shifting transformers, two synchronous condensers, and 4 shunt reactors.
In one other main milestone for the mission, building companion Elecnor stated it has constructed the primary of 334 “Danubio” towers designed to hold heavy quad 500 kV conductor bundles from Wagga Wagga to Dinawan substation.
Elecnor Australia Project Director Filipe Delgado stated the connection course of required technical experience and collaboration involving key civil, electrical, building, commissioning, and overhead transmission line specialists.
Construction of the South Australian part of EnergyJoin was accomplished in December 2023 by South Australia’s grid proprietor ElectraNet, which is liable for a 206 km part of the cable within the state.
As the primary main new transmission line inbuilt Australia in about 15 years, the mission is anticipated to permit greater than 2 GW of photo voltaic, wind, and battery tasks to connect with the grid.
