  1. Energy Storage Technology Options for Distribution Networks – More than just the economic cost USAEE – Anchorage Craig Froome, Liam Wagner and John Foster July 2013 @gcitweet /gciuq

  2. 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?

  3. What are we doing at UQ?

  4. Global Cumulative Installed Capacity Source: IRENA 2012

  5. Data Modeling

  6. Capexwith respect to Power and Energy Provision

  7. 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%)

  8. Battery Technical Specifications

  9. Levelised Cost of Storage

  10. 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.
