that will deliver faster and better coordinated         delivery of transmission network hosting capacity
development of REZs. These two measures are:            and REZ development in Victoria. VicGrid will seek

• The creation of a REZ development body                the Energy Security Board’s REZ framework and
  responsible for actively delivering Victorian REZs    the proposed ‘efficient management of system
  (VicGrid); and                                        strength’ rule change currently being assessed by
• The $540 million REZ Fund, to invest in REZ           the Australian Energy Market Commission to enable
  network infrastructure solutions.                     timely and efficient development of Victoria’s REZs.

the above objectives.

The Government is developing a framework to guide
investment in RDP projects and to determine the
most appropriate funding pathways and government
funding options for RDP projects once approved.
This framework will be released as part of the REZ
Implementation Plan in July 2021. Initial development
suggests several factors will be considered when
determining the most appropriate funding pathway,
including whether:

1. the investment can be undertaken under the
   existing regulatory framework;
2. the investment is scale efficient and enables
   multiple new generators to connect to the
   network, now or in the future;
3. beneficiaries can be readily identified to
   contribute to the cost of the investment;
4. the investment delivers on key public policy
   objectives.

Project description (overview and purpose)                                        Risk of delivery
Installation of a new synchronous condenser in the Haunted Gully
area.
                                                                                      Medium
This project will increase system strength and ensure sufficient
available fault level for new renewable generators to comply
with their system strength connection compliance obligations.
                                                                                   Environment
This project would avoid the need for individual synchronous
condensers to be constructed and represents a scale efficient                     Project location within cleared
solution to system strength remediation, reducing capital                         agriculture land may minimises
