Battery of the Nation boost


There's another boost for Tasmania's bid for a second power cable over Bass Strait.

The body which oversees Australia's wholesale electricity market is apparently on board with Tasmania's Battery of the Nation plans, if a new issues paper being released today is anything to go by.

The Australian Energy Market Operator study says another interconnector would play a part in shoring up the country's energy resilience if coal plants are retired sooner than expected.

With memories still fresh of the huge South Australian blackout in 2016, which the AEMO blamed in part on the increasing use of renewables, Hydro Tasmania is welcoming the latest thumbs-up for battery of the nation.

It's in the feasibility stage with three potential pumped hydro dams to generate 1.7 gigawatts for the national grid if it goes ahead. 

“Tasmania has significant storage capacity just waiting to be developed and our long duration pumped hydro is one of the most cost-competitive storage options available," said Hydro Tas CEO Steve Davy. 

“One of the major advantages of our pumped hydro is that it can be developed in stages, which will ensure ongoing reliability and energy security as the market develops."
