International case studies on microgrids and utility scale energy storage: Common threads to optimise systems and monetise value

14.00 – 15.15 | Friday 14 June 2019

Claude Morris is GHD’s microgrid technology leader in Western Australia. He is a recognised industry specialist in this area, having worked on microgrids for the past 10 years. After successfully completing the integration of several microgrids and large-scale battery installations throughout regional Western Australia, Claude moved to the UK to work on projects in the Middle East, UK, North America, Asia-Pacific and Africa. Now back in Australia he brings a wealth of international microgrid and battery energy storage experience and knowledge which can be applied to GHD’s Australian client’s projects.

Load shifting

The following key areas will be focused on:

  1. Universal and discrete drivers for microgrids and utility scale storage optimisation
  2. International case studies focusing on market trends and lessons learned including:
  • Balancing and ancillary services market reform or creation
  • Sizing, operating modes and stacked value proposition
  • How technology agnostic are technology agnostic projects
  1. Defining “optimisation”  in the context of microgrids and the importance of clear target criteria and precedence:
  • Levelised cost of energy, installed capacity or renewable penetration…what is best?
  • Energy storage sizing: stability or load shifting…or both?
  • How to best cater for sensitivities in highly volatile models
  • Hidden costs material to optimisation
  • Technical limitations vs commercial optimisation: different sides of the same coin
  1. Interplay between key parties with respect to risk apportionment of performance guarantees, technical and commercial barriers including:
  • Duty cycle risk
  • Capacity maintenance
  • Take or pay and curtailment risk
  • Intellectual property disputes
