Frequency Control and Ancillary Services (FCAS)

Enhar assist solar farm and battery developers through feasibility, business case, land acquisition, design, planning, grid connection and engineering.

Our most recent project work with local and international clients has involved concept detailed design in mid-ranges sized solar farms and the addition of large battery storage. This involved revenue modelling for both the solar farm and battery storage integrating revenue optimisation through Frequency Control and Ancillary Services (FCAS) modelling, ancillary services and other potential revenue streams. From a technical point, some risk is mitigated through smoothing of generation, load shifting opportunities and the impact of loss factors.

Why is FCAS important?

In some cases extreme weather, interconnector failures, risk of islanding, changing nature of load and coal-fired generator outages have all combined to contribute to increased FCAS requirements. The addition of large batteries in NEM regions creates opportunities for grid stabilisation which were previously not possible. Due to the extreme speed with which batteries can respond, a financial opportunity to capitalise in this area presents itself.

Indicative modelling for the projects undertaken was up to 40MWp solar PV and 80MWh BESS.

Enhar throughout the project have provided site identification including substations and 'non-network' opportunities, land acquisition planning permits, detailed engineering design and grid connection approvals.
