Geraldine Slattery:

*“We are exploring ways to repurpose Mt Arthur Coal’s 7,000+ hectare site to sustain jobs and investment. Pumped hydro could play a key role in the region’s future.”*

How Pumped Hydro Works

  • Stores energy by moving water between two reservoirs at different elevations.
  • Generates power on demand by releasing water through turbines.
  • Mine sites are ideal due to:
    ✓ Existing elevation differences
    ✓ Large catchment areas for reservoirs
