Energy security

By international standards, Tasmanians enjoy extremely reliable access to energy such as electricity, natural gas and petroleum products.

If disruptions to energy supply occur, it’s usually due to severe weather impacting the electricity network. Less commonly, issues with fuel transportation or shortages interrupt natural gas or petroleum supply.

The Government is responsible for the security and safety of electricity, natural gas and liquid fuels, and procedures for managing energy supply disruptions in Tasmania align with national standards. The Government also has emergency powers to use in situations that cannot be managed by industry alone.

While intervention is seldom required, the Government heightens its monitoring and coordination activities when energy security risks increase.

Water storage management

Prudent management of water storages for generating hydro-electricity is essential for Tasmania’s energy security.

The Government ensures water storages are managed in line with the Energy Security Risk Response Framework (Chapter 10).

To support the Framework recommendations, amendments were made in 2019 to the Energy Co-ordination and Planning Act 1995.

Under the Energy Security Risk Response Framework the Monitor and Assessor oversees water storage management, with reference to a Prudent Storage Level (PSL) and a High Reliability Level (HRL). If storage levels fall below the PSL or HRL, an escalating series of actions are taken (first by the Monitor and Assessor, or if levels fall below HRL, by the Energy Security Coordinator) to ensure appropriate planning and action is taken to restore adequate water storage levels.

Monthly and annual Monitor and Assessor reports can be found on the Office of the Tasmanian Economic Regulator website.
