The Battery of the Nation initiative, being led by Hydro Tasmania, is investigating and developing options to expand renewable storage and generation in Tasmania.
Focusing on pumped hydro energy storage (PHES), BotN would also require upgrades to transmission and interconnection to the NEM through the complementary Marinus Link project.
An ARENA-funded concept study has reduced a list of over 2,000 potential pumped hydro options in Tasmania to 14, which Hydro Tasmania has narrowed down to three.
In February 2019, the Federal Government through Hydro Tasmania committed $30 million to take the first phase of Battery of the Nation to investment stage by 2021.
In March 2019, Hydro Tasmania revealed three sites selected for further investigation from the original list of 14 potential pumped hydro options:
- Lake Cethana in Tasmania's North West, with 12 hours of storage capacity
- Lake Rowallan, also in the North West, with 24 hours of storage capacity, and
- Tribute Power Station on Tasmania's West Coast, with 31 hours of storage by establishing a new connection between Lake Plimsoll and Lake Murchison.
In April 2020, Hydro Tasmania released a series of brief papers supporting the case for 'deep storage' as part of the future energy market. The papers were jointly funded by ARENA.
A feasibility study is being prepared to develop the case for the project and assess the suitability of each of the sites for development.
