The Second Bass Strait Interconnector (Marinus Link) is a proposed 1,200 MW interconnection between Tasmania and Victoria.

In November 2017, TasNetworks announced it would undertake a $20 million assessment of the feasibility and business case for a second Bass Straight interconnector, with assistance from the Federal Government's Australian Renewable Energy Agency (ARENA). The business case follows the Tamblyn Review, which was an initial report into the feasibility of a Tasmanian second interconnector, released in April 2017.

In July 2018, TasNetworks released the Project Specification Consultation Report for public consultation, which examines the case for further interconnection between Tasmania and Victoria. The document applies the regulatory test for transmission (RIT-T) process to determine whether the project is in the long-term interest of customers.

The business case study was released in February 2019 and examines the preferred route, optimum size, cost estimate, revenue investment test and financial model for a second interconnector between Tasmania and Victoria.

The Federal Government has committed $56 million towards the project, and committed to develop an underwriting mechanism through its Underwriting New Generation Investments program. The Tasmanian Government has also committed up to $30 million to support the feasibility assessment of three shortlisted pumped hydro energy storage sites in north-western Tasmania, and to advance the first of these sites to final investment decision by 2021.

The 2019-20 Federal Budget confirmed an allocation of $56 million of funding in FY2018-19 to accelerate the Marinus Link Interconnector.

The project is included under the broader National Electricity Market, which Infrastructure Australia identifies as a High Priority Initiative on its Infrastructure Priority List. The project was previously listed a Priority Initiative of long term (10-15 years) importance.
