Appendix "J" Connection enquiries in Southern NSW • Currently more than 15,000MW of generation enquiries across Southern NSW • Network capacity of approximately 1,000MW • Significant energy resources in the region which network require investment development • Regulated network expansion will remove constraints and unlock potential
Appendix "J" Integrated System Plan • One of the Finkel Review recommendations • Provides a co-ordinated approach to incorporating renewable generation, supported by storage, into the grid as coal- fired plant ages and is retired over the next 20 years • Three groups of investment are recommended comprising: • Group 1 - Immediate • Group 2 - Mid- 2020’s • Group 3 - Mid 2030’s and beyond • ISP Projects align with TransGrid’s Contingent Projects submitted to the AER Source: AEMO Integrated System Plan

Appendix "J" Why the ISP is important • A more connected NEM will facilitate increased competition, deliver lower prices and increase security as more intermittent generation enters the system • Each part of the energy supply chain will need to play their part to deliver reliability, affordability and emissions reduction Source: AEMO Integrated System Plan (ISP)
Appendix "J" NSW Transmission Infrastructure Strategy The NSW Government’s Transmission Infrastructure Strategy outlines three initiatives: 1. Boost interconnection with Victoria, South Australia and Queensland, and unlock more power from the Snowy Hydro Scheme. Increase NSW’s energy capacity by prioritising Energy Zones in the Central 2. West, South West and New England regions of NSW. 3. Work with other states and regulators to streamline regulation and improve conditions for investment.
