Project

  • Federal Government Solar Flagships Program
  • 3.275MW Solar Research Array
    • Flat panel with single and dual axis tracking
  • Battery Storage on both AC and DC side
  • But what storage options?
levelised cost of energy
Levelised Cost of Energy

LCOEJ = Levelised Cost of Energy for Technology

TOCJ = Total Operating Cost

O&MJ= Operations and Maintenance Costs (All Fixed in this study)

RE(t)J= Renewable Energy Certificates (~$40/MWh Sent out)

WACC= Weighted Average Cost of Capital (Post-tax Real ~7.23%)

CAPEXJ = Capital Cost

SO(t)J= Energy Sent out to the Grid

CPI(t)r = CPI applied to revenue stream 1.875% (ie. 75% of prevailing CPI 2.5%)

slide11

Future

Cost of storage is decreasing and through learnings (and greater deployment) will continue to decrease in next decade.

Large-scale deployment of renewable technologies can not happen without storage.

Technology choice will be dependent on use – different technologies do have different purposes.
