AFFORDABILITYEMISSIONS
REDUCTION
• Australia’s energy system is undergoing a
period of immense change
• Solving the energy trilemma will remain a
key objective
• The transition to the energy system of the
future will need to be planned
• Transmission will play an essential role as a
platform for the connection and trading of
large scale and geographically dispersed
renewable generation

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"
• 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

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

Appendix "J"
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.
2. Increase NSW’s energy capacity by prioritising Energy Zones in the Central
West, South West and New England regions of NSW.
3. Work with other states and regulators to streamline regulation and improve
conditions for investment.
