2. Context 2.1 Victoria’s renewable energy The development of REZs across the state is a key transformation initiative in Victoria’s energy transformation. REZs are areas of abundant renewable energy resources Victoria’s coal-fired power stations are increasingly such as solar and wind, the full development of which aged and unreliable. The future reliability of Victoria’s can ensure the timely and cost-effective delivery of energy supply, and the economic and social benefits secure and clean energy for Victoria. Figure 1 shows that this provides, is contingent on the development a map of the six REZs that have been identified in of a diverse, secure and affordable state-wide Victoria through the AEMO Integrated System Plan generation portfolio, delivered in a timely fashion. (ISP): South West Victoria, Western Victoria, Murray River, Central North, Ovens Murray and Gippsland. Victoria is delivering on an ambitious agenda to increase the share of electricity produced from The benefits of developing Victoria’s REZs extend renewable sources. The Victorian Government has beyond direct increases to renewable energy legislated renewable energy targets (VRET) of 25 per generation, to include supporting investment cent of electricity generation by 2020, 40 per cent by in local economies, creating local jobs, and 2025, and 50 per cent by 2030. The 2020 target has strengthening local supply chains. Victoria currently been achieved and we are on track to achieve the leads other states in renewable energy jobs, 2025 and 2030 targets. accounting for 7,800 jobs in 2020, or 30 per cent of total jobs in the renewables sector in Australia. Significant investments have been made to The development of the Renewable Energy Zones support the achievement of the VRET, including will generate thousands of construction jobs right the Victorian Renewable Energy Auction Scheme across regional Victoria, as workers build our next which has contracted for 928MW installed generation of solar and wind farms, energy storage generation capacity.

Developing the renewable energy opportunities The Government has also partnered with industry presented in all regions will necessitate to implement large scale battery projects in key transformation from a power system that has areas of the state, including the 300MW Victorian traditionally supplied electricity from a small Big Battery near Geelong. number of very large electricity generators to a new system that connects the many new The benefits of this energy transformation are generation projects geographically dispersed clear.

The steady increase in renewable energy projects in Victoria is contributing to lower prices and greater reliability for consumers. The REZ Development Plan will be designed to ensure this trend can continue. Victorian Renewable Energy Zones - Development Plan Directions Paper 3

Together these investments could enable an REZ Implementation Plan in July 2021.

From a network perspective the Ovens Murray REZ is not The potential solutions identified reflect both experiencing immediate system strength issues and anticipatory medium-term transmission has adequate network capacity to accommodate developments to enable future REZ development, as expected generation development. VicGrid will well as technical solutions that could be progressed play an active role in planning and facilitating in the near term to support the efficient connection significant renewable energy development in all six of Victoria’s existing pipeline of renewable energy REZs including the need for continued monitoring of projects. This initial RDP exclusively focuses on emerging required network investments. transmission network development within Victorian REZs and is divided into two stages: • Stage 1 projects are investments that the Victorian Government could immediately progress to deliver shorter-term grid remediation solutions in areas where network limitations are impeding renewable energy projects. • Stage 2 projects are potential medium-term investments in REZ infrastructure that will involve further assessment and community and stakeholder consultation. 7
3.1 Stage 1: Immediate priority projects By supporting these investments sooner than the long timeframes of regulatory investments, to support REZs such as the RIT-T, means more lower cost The Victorian Government and AEMO have worked renewable generation can enter the market for together to develop a list of potential immediate the benefit of consumers, as well as providing priority transmission network upgrade projects non-market benefits such as local economic to support existing and future renewable energy activity and jobs. Such scale efficient investments generation development in Victoria’s REZs.

REZ Governance and Funding As part of the 2020-21 Budget, the Victorian VicGrid will build on the Victorian Government’s Government announced two major new initiatives existing leadership to address barriers to the timely 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 to leverage and complement initiatives such as • 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. 4.1 Establishing VicGrid The Victorian Government will establish VicGrid Questions: in mid 2021, tasked with the overarching planning and development of Victorian REZs.

4.2 Funding pathways for RDP The Government’s $540m REZ Fund can be used in a variety of different ways to facilitate RDP projects and REZ Fund solutions including: The Government intends to release details of the • funding investment gaps to bring forward Stage 1 RDP projects for immediate financing from network projects under RIT-T processes where the REZ Fund in May 2021, including procurement appropriate; and cost recovery models for each investment, including local content requirements. Projects • direct grant funding or co-funding of projects; outlined in Stage 2 of the RDP could be financed and through several pathways, including the use of • financing of investments with cost recovery from regulatory powers (e.g. use of Victorian NEVA beneficiaries. powers to modify or disapply the RIT-T process), public funding (including the REZ fund), private Importantly, any project that is considered for investment or a combination of these pathways. government support must demonstrate a net benefit. When assessing the use of the REZ Fund, Future development and financing of network the Government will consider the benefits of public projects in the RDP will be guided by an assessment funding in REZ infrastructure including network of net beneficial investment for Victoria, aligned and consumer benefits, support for achieving with supporting efficient and sustainable renewable government VRET targets, economic and industry energy development in the REZs, and achieving development objectives, the priorities of local value for money for taxpayers and electricity communities, local content opportunities, and consumers. Funding pathways for projects identified the ability to provide value for taxpayer funding, in the RDP will be case-specific in order to achieve including cost recovery of investment. 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.
