The 2020 Integrated System Plan (ISP) provides an actionable roadmap for eastern Australia’s power system. The ISP draws on extensive stakeholder engagement and internal and external industry and power system expertise to develop a blueprint that maximises consumer benefits through a transition period of great complexity and uncertainty.  

The ISP is a whole-of-system plan that efficiently achieves power system needs through that transformational period, in the long-term interests of the consumers of electricity. It serves the regulatory purpose of identifying actionable and future ISP projects, as well as the broader purposes of informing market participants, investors, policy decision makers and consumers.
