The project will recieive access to a concessional loan from the Rewiring the Nation plan, through the Clean Energy Finance Corporation, for approximately 80 per cent of the costs. The additional 20 per cent is to be an equity investment between the Commonwealth, Victoria and Tasmania. Originally, the equity investment was to be shared equally between the three governments (agreed in October 2022). However, in September 2023, the Federal and Tasmanian Governments announced a new agreement had been reached which would see the Federal Government's equity contribution increase to 49 per cent and the Tasmanaian Government's contribution decrease to 17.7 per cent. The Victorian contribtuion is to remain at 33.3 per cent. |
