Business case for large battery addition to 40MW solar farm

Solar Farm

Modelling financial viability of large scale storage for arbitrage and FCAS.

Key Achievements:

Impact

  • Feasibility study and financial model for adding a large scale battery to a 40MW solar farm in Victoria.
  • Financial modelling of revenue streams including FCAS income for the battery, plus the economics of network charges.
  • The model considered spot price revenue from the solar farm before the addition of a BESS, and the impact on revenues and IRR with a BESS.

Project Challenges

  • FCAS forecasting uncertainty  - we used Global Roam data for historic FCAS values, plus AEMO data on FCAS revenues.
  • Changing regulations regarding TUOS charges for batteries.
  • Complex financial model co-optimising multiple targets.
  • Simulation of battery behaviour to optimise revenues.
