Our current projects
The projects we undertake strengthen our electricity network to ensure we can meet your needs now and into the future.
We review the electricity network every year to identify constraints and emerging issues. This strategic review is published as our Annual Planning Report, which highlights where development or changes in the network may be required to maintain system security, quality and reliability.
Regulatory investment test for distribution (RIT-D) projects

| Extending distribution network operational capability | To ensure power system security and to continue to meet customer expectations around the quality and reliability of electricity supply, we’ve identified the need to enhance our distribution control system capability. We propose to do so via the implementation of a distribution management system. | Download (PDF) |

| Project Marinus - Second interconnector assessment |
With support from the Australian Renewable Energy Agency, we are assessing the viability of further interconnection between Tasmania and the rest of the National Energy Market. We released our Project Specification Consultation Report (PDF) and summary (PDF) for public consultation in July 2018 and submissions closed in October 2018. These submissions are available on the Project Marinus website. We also published an additional report, outside of the RIT-T process, in February 2019: the Initial Feasibility Report. This report, and submissions we received in response, are available on the Project Marinus website. In December 2019 we published the Project Assessment Draft Report (PDF) and summary (PDF). We also published a Business Case Assessment Report (PDF) and summary (PDF) which covers items beyond the scope of the RIT-T. Submissions to the Project Assessment Draft Report closed in April 2020. |

Substation disconnector and earth switch replacement |
Spare parts are no longer available for 33,245 kV disconnector/earth switches at Burnie, Chapel Street, Liapootah, Wayatinah and Palmerston substations and the electrical and mechanical condition of these assets has deteriorated to a point where they require replacement to maintain acceptable levels of supply reliability. |

Lindisfarne Substation transformer T2 and T3 replacement |
Lindisfarne substation supplies customer loads at Geilston Bay, Cambridge, and Bellerive zone substations via a 33 kV sub-transmission network. Lindisfarne substation transformers T2 and T3 are 110/33 kV 30/45 MVA units that were made in 1964. The condition of both transformers has been identified as poor and requiring replacement. |

George Town- Comalco transmission line renewal |
The George Town-Comalco 220 kV transmission line was constructed in 1967 to supply the aluminium smelter at Bell Bay and consists of four galvanised steel lattice support structures strung with aluminium conductor steel-reinforced cable. Recent inspections have highlighted numerous corrosion issues and replacing the transmission line is required to maintain acceptable levels of supply reliability. |
