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?
Global Cumulative Installed Capacity Source: IRENA 2012
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%)
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.
