As a result, Cornwall Insight Australia has announced an increase in its Frequency Control Ancillary Services (FCAS) price forecast from 15 to 20 years to align with the increase in the lifetime of battery storage assets.
“The energy market is accelerating towards a net zero transition” said Ben Cerini, Principal Consultant at Cornwall Insight Australia. “As a result, Storage and system services are playing increasingly important roles in the NEM to keep the system safe and secure, provide firm dispatch and deliver services essential to the continued penetration of renewables. In our latest FCAS price forecast, we acknowledged that the lifetime of battery storage assets are increasing from what was a 10-15 year life only a few years ago to up to 15-20 years today (depending on warranties and cycling requirements). In light of this, we have extended our FCAS forecast from 15 to 20 years to better align with our client’s needs.
FCAS currently makes up a significant proportion of most storage business cases. Understanding each service’s price drivers and expected price changes will affect future project connection size and duration and the optimal time for refurbishment and extension planning. The extended duration of the curves allows new project developers to better understand the potential future FCAS cost liabilities for their assets, for a more significant portion of their operational life, to better reflect actual future costs.
Extending our FCAS curves to 20 years provides our client with a more robust future projection of revenues and cost for projects. Furthermore, as more storage projects come to a financial close, robust and accurate FCAS curves are essential for favourable financing and project completion.”
