Enerven has been appointed to connect two 120 MW BESS facilities, Summerfield BESS1 and BESS2 to ElectraNet’s network, including design, supply, and construction of a new greenfield 275kV Tepko substation adjacent to the established BESS facilities, augmentation of the Tungkillo substation, and adding 17km of new 275kV transmission line using the existing towers.
The customer
ElectraNet is South Australia’s leader in electricity transmission, operating over 5,600 circuit kilometres of transmission lines and more than 90 high-voltage substations across a vast area of over 200,000 square kilometres. This project facilitates the connection of new generation from the SE Renewable Energy Zone.
“This project reinforces Enerven’s commitment to delivering resilient grid infrastructure and connecting communities to cleaner, more reliable power.”
