    • 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

  • • 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

  • 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

  • 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.
