澳大利亚新南威尔士州政府宣布投入2.25亿澳元，用于升级南部可再生能源区(South West REZ)的电网基础设施[1]。这一升级计划在耗资36亿澳元的Project EnergyConnect输电线项目完成仅数月后启动[1]，旨在提升电网容量以支持计划中的风能和太阳能项目[1]。
升级工程将由能源运营商Transgrid承担，主要内容包括将Dinawan变电站和Wagga Wagga输电线的容量从330千伏提升至500千伏[1]。根据计划，工程预计于2027年启动，耗时两年完成[1]。Transgrid已与澳大利亚能源监管机构(AER)签订项目发展契约[1]。
值得注意的是，Project EnergyConnect的最终成本达36亿澳元，较初期预算的23亿澳元超支56%[1]。
The New South Wales government has committed $225 million to upgrade energy infrastructure in the South West Renewable Energy Zone, mere months after completing the Project EnergyConnect transmission line [1]. The upgrades are designed to increase grid capacity to support planned wind and solar projects in the region [1].
Transgrid will undertake the upgrade work, which includes boosting capacity at the Dinawan substation and the Wagga Wagga transmission line from 330 to 500 kilovolts [1]. The project is expected to begin in 2027 and will take two years to complete [1]. Transgrid has already entered into a project development agreement with the Australian Energy Regulator [1].
The new investment follows the completion of Project EnergyConnect, which reached a final cost of $3.6 billion, representing a 56 percent increase over its initial $2.3 billion budget [1].
