  • Strong fault level support from dual 330 kV in-feeds (Sydney South / Sydney West)
  • Lower risk of voltage flicker and harmonics vs weaker regional nodes
  • 紧邻 Liverpool BSP——短馈电线(降低资本开支及损耗)
  • 可在 330 kV 并网,容量达 200+ MW
  • 双 330 kV 进线提供强故障水平支撑(Sydney South / Sydney West)
  • 电压闪变和谐波风险低于弱区域节点

MLF (Marginal Loss Factor): MLF affects how much revenue is realised at settlement after transmission losses. MLF > 1 is beneficial; it can improve delivered revenue and bankability compared with remote nodes. Prestons is in the Sydney load zone near Liverpool BSP; proximity to load supports stronger MLF outcomes. MLF 影响结算时扣除输电损耗后的实际收入。 MLF > 1 有利,可提升实际收入及可融资性。 Prestons 位于 Sydney 负荷区近 Liverpool BSP,贴近负荷支撑更优 MLF 表现。

Exit Pathway at FIDFID 退出路径

Exit Timing退出时机

At Final Investment Decision (FID), ESR facilitates entry of long-term, lower-cost infrastructure capital (super funds, infra funds).

Devex investors realise value uplift at FID exit.

在 FID 时,ESR 促成长期低成本基础设施资本进入(养老基金、基建基金等)。

Devex 投资者在 FID 退出时实现价值提升。

Capital Transaction资本交易

Devex investors can:

  • Exit fully at FID and realise returns, or
  • Reinvest alongside ESR and new capital in the build-own-operate phase

ESR 负责交易执行及向新投资人移交。

Devex 投资者可:

  • 完全退出并在 FID 实现回报,或
  • 再投资与 ESR 及新资本共同进入建设-运营阶段

ESR’s RoleESR 的角色
