Turning FCAS Into a Revenue Stream: How IPPs Can Profit from Grid Instability

As Australia transitions into a renewable-dominated energy market, Independent Power Producers (IPP’s) are standing at a pivotal crossroads. The challenges of grid instability, frequency volatility, and increasing compliance demands are clear. Yet, so is the opportunity to turn these challenges into lucrative advantages.

Once dismissed as a regulatory necessity and cost, Frequency Control Ancillary Services (FCAS) have emerged as a viable and significant revenue stream. The numbers tell a powerful story: FCAS markets have expanded at an astonishing pace—from AU$5 million in 2014 to AU$65 million in just two years¹, with Queensland alone incurring AU$234 million in FCAS costs in 2021². These are not just abstract figures—they represent a monumental opportunity for IPPs equipped to respond to the grid’s needs.

This figure shows the quarterly average enablement amount for each FCAS service across the NEM for the past five years. These include average enablement amount for both raise and lower regulation services, and raise and lower contingency services (fast - 6 second, slow - 60 second, delayed - 5 minute).

The key lies in leveraging the right technology to address these challenges while optimising contingency FCAS participation. Enter the VECTO System, a state-of-the-art combination of VECTO 3 hardware and its accompanying FCAS module. This system redefines the way IPPs approach frequency management, turning technical hurdles into avenues of growth and profitability.

What is FCAS?

The power system must maintain balance between electricity generation and use at all times. When demand exceeds supply, system frequency drops. When supply exceeds demand, frequency rises. In Australia, if frequency moves outside 47-52Hz, the system will shut down to prevent equipment damage, leading to blackouts like the South Australia event in September 2016. AEMO‘s key role is to prevent these disruptions by keeping generation and demand in balance.

FCAS help maintain this critical balance. FCAS providers can quickly adjust their power output or consumption to help keep the system frequency at 50Hz/60Hz. These services work in two ways: regulation FCAS makes small, continuous adjustments, while contingency FCAS responds to sudden, major changes in the system. This creates a stable and reliable power network.

The Grid at a Tipping Point: Challenges and Opportunities for IPPs

Australia’s energy market is undergoing a seismic shift. As traditional, rotational-inertia-heavy power sources are replaced by Inverter Based Resource (IBR) based renewables, the grid’s ability to self-stabilise is weakening. The result? A rapid increase in the Rate of Change of Frequency (RoCoF) following disruptions, with frequency deviations becoming deeper (nadirs) and faster.

For IPPs, this presents two opposing realities:

The Challenge: Grid instability increases the likelihood of disconnections, curtailment, and revenue loss. Compliance requirements for FCAS participation are stringent, demanding precise measurement, reporting, and rapid response capabilities that strain many existing systems.
The Opportunity: These very instabilities have made contingency FCAS a critical tool for grid management, and providers of fast, reliable frequency support stand to gain significant revenue. In 2020 alone, grid-connected batteries (BESS) earned in the region of AU$50 million in FCAS revenue during separation events³—a testament to the financial potential of participating in ancillary services.

Why FCAS Is a Goldmine for IPPs

Historically, FCAS has accounted for only 1-2% of total energy costs. But as grid dynamics evolve, this figure has risen sharply. By Q1 2020, FCAS accounted for 8% of total energy costs, translating to AU$310 million in system costs. For IPPs, this is a clear signal: the demand for frequency control services is real (and profitable⁴).

Specific instances underscore this growing opportunity:

Queensland’s Solar Curtailment: In 2019/20, 178 GWh of generation capacity was curtailed, with 97 GWh of this economically driven. With precise frequency support and advanced monitoring, IPPs could have mitigated these losses and turned curtailment into revenue opportunities.
Very Fast FCAS (VF FCAS): The introduction of VF FCAS, which demands near-instantaneous response times, has opened up an entirely new market segment. This represents both a challenge and a lucrative frontier for IPPs capable of meeting these stringent requirements.

Addressing Barriers: Why Many IPPs Struggle to Access FCAS Markets

Despite its potential, many IPPs find themselves sidelined from FCAS markets. The reasons are clear:

Complex Compliance Requirements: Manual processes for collecting and verifying data, correlating timestamps, and generating reports are labor-intensive and prone to errors.
High Technical Standards: Contingency FCAS participation demands precision in monitoring, reporting, and response, with stringent requirements for accuracy and speed.
Operational Inefficiencies: Without streamlined systems, engineering teams are forced to devote significant hours to compliance rather than optimising performance.

These challenges create a barrier to entry that prevents many IPPs from fully capitalising on the contingency FCAS opportunity.
