Marinus Link has obtained the first Transmission and Infrastructure License granted under Australia’s new marine electricity infrastructure regime, the approval allows the project to move into the construction phase after completing one of the final regulatory processes required by the Australian Federal Government. This authorization represents a significant step forward in the development of a submarine electrical interconnector designed to connect northwest Tasmania with the Latrobe Valley region in Victoria, the infrastructure will include submarine power cables and associated fiber optic systems intended to transport electricity across Australian Commonwealth waters.
The license was granted to Marinus Link Pty Ltd within the framework of Offshore Electricity Infrastructure Act 2021, a regulatory framework created to facilitate the development of marine energy facilities and electric transmission systems in federal waters.
Marinus Link is moving forward with its marine transmission license
Obtaining the Transmission and Infrastructure License this represents one of the last regulatory permits required before construction can begin. The authorization allows for the installation, operation, maintenance, repair, and decommissioning of the submarine power line cables, as well as the fiber optic infrastructure linked to the system. This permit complements the environmental approval previously obtained under the Law on Environmental Protection and Biodiversity Conservation of 1999 of the Commonwealth with both authorizations completed, Marinus Link it has the necessary regulatory support to move forward to the next stages of implementation.
The license will be valid until 2090 and establishes a long-term operational framework for the submarine electrical infrastructure. It also incorporates protective measures for the cable route and safety zones designed to reduce potential interference with maritime activities. The CEO of Marinus Link Pty Ltd, Stephanie McGregor he noted that the approval will allow electricity to be transported through Commonwealth waters and protect the planned location for the submarine cable system.
An electrical interconnector between Tasmania and Victoria
The project is an electricity transmission project designed to connect Tasmania to the Australian mainland power grid via a submarine link across the Bass Strait the infrastructure includes a first phase with a transmission capacity of 750 MW and an approximate route of 345 kilometers between northwest Tasmania and Victoria. The system will combine underwater sections with land segments until it reaches the Latrobe Valley area.
The project’s main objective is to improve connectivity between regions with different electricity generation profiles. Tasmania has significant hydroelectric capacity, while Victoria has a growing share of renewable sources such as solar and wind power. The interconnection will increase electricity exchange capacity between the two territories and provide greater flexibility to the Australian energy system. Submarine cables will allow electricity to be transported more efficiently between generation areas and consumption centers.
In addition, the project incorporates a fiber optic network associated with the electrical cables, providing additional communication, supervision and monitoring capabilities for the operation of the link.
Australia promotes marine electrical infrastructure
The approval of this project comes within the new Australian regime for marine electrical infrastructure, established by the Marine Electrical Infrastructure Act of 2021 this legal framework defines the necessary conditions for developing electrical projects in the waters of the Commonwealth and establishes the regulatory procedures for the authorization, construction and operation of submarine installations.
One of the central aspects of the regime is the creation of protection mechanisms for critical infrastructure installed in marine environments. In the case of the project, the license establishes safety zones around the submarine power cables to reduce risks associated with activities such as vessel anchoring. The development of this regulation aims to provide greater regulatory clarity for projects that need to operate in federal maritime areas. The first license granted under this system makes this project a benchmark within the new Australian framework for marine electricity transmission.
Next steps before construction
After receiving the license, Marinus Link Pty Ltd the process will continue with the submission of the design notification and the development of a project management plan. This document will define the methodology for carrying out the activities related to the construction, operation, maintenance, repair, and future decommissioning of the subsea electrical infrastructure.
The plan will also incorporate measures to manage activities within the marine environment safely and responsibly. Its development will involve a consultation process with various stakeholders, including Indigenous Peoples, users of the maritime space, government agencies, and coastal communities. The participation of these sectors will allow for the integration of diverse perspectives on the use of the marine area where the cables will be installed and on the future operation of the transmission system.
Preparatory work for Marinus Link began this year and construction is scheduled to proceed in the coming months, once the corresponding administrative and technical stages are completed.
A project to strengthen Australia’s electricity grid
Marinus Link is part of a series of projects aimed at expanding Australia’s electricity transmission infrastructure and improving the integration of renewable energy sources into the national energy system. The connection between Tasmania and Victoria will strengthen electricity transfer capacity between regions and facilitate greater coordination among different generation sources.
The combination of submarine cables, terrestrial infrastructure, and communication systems makes Marinus Link a highly complex technical project, requiring coordination among authorities, communities, and specialists throughout its lifecycle. With the first Transmission and Infrastructure Licensegranted under theMarine Electrical Infrastructure Act of 2021 Marinus Link enters a new phase focused on the execution of an infrastructure designed to operate for several decades.
The progress of the project will be followed by the energy, industrial and technological sectors due to its relationship with the expansion of modern electricity networks and the incorporation of new transmission capacities for the Australian energy transition.
