Leveraging Pumped Hydro to Stabilise the Grid: An EnergyAustralia Perspective

Leveraging Pumped Hydro to Stabilise the Grid: An EnergyAustralia Perspective

“Batteries, wind and solar power can put a lot of energy into the system but they can’t materially improve its strength or provide any traditional inertia at present, because they have no large controllable spinning mass of synchronous generation to stabilise the grid,” explains Julian Turecek, Head of Assets, EnergyAustralia.

“By putting between 100 and 250 megawatts of generation at our hydro project at the tip of the Spencer Gulf, we are effectively able to put back significant strength and inertia into a remote part of the grid which will make it far more resilient to cope with frequency and voltage disturbances,” he said.

Ahead of Power Grid Resilience 2017, Julian explores the economics of pumped hydro and a glimpse into the vision of EnergyAustralia’s Spencer Gulf pumped hydro project and how it has the potential to stabilise the grid.
