Hydro Tasmania has announced it is accelerating detailed investigation of three key opportunities for pumped hydro development in the Australian state as part of the Battery of the Nation initiative.

Work has begun on a full feasibility assessment of pumped hydro development opportunities at Lake Cethana and Lake Rowallan in the North-West and near Tribute Power Station on the West Coast. This will involve grassroots community engagement, geotechnical investigations and environmental, heritage and social assessments.

The Board of Hydro Tasmania has approved funding for this work to begin, as part of the first tranche of investment by Hydro Tasmania of up to $30 million for deeper studies of the three options.

The studies will identify a single pumped hydro project that can be ready to operate when 1200MW of additional Bass Strait interconnection comes online.
