Enel X VPP FCAS market leadership

Keeping the electricity grid stable at all times with Frequency Control Ancillary Services

What is FCAS?

Frequency Control Ancillary Services (FCAS) play an important role in protecting the power grid against sudden failures within large power stations or power transmission networks. FCAS is increasingly important as we add more renewables to the power grid, especially that provided from new technologies

Four years ago, nearly all of FCAS came from traditional fossil fuel power stations.  Following a 2017 rule change that opened the market to virtual power plants (VPPs), Enel X was the first new market entrant to register a VPP in the FCAS market.


Enel X's Virtual Power Plant

Our VPP is built from a network of electrical equipment - distributed across 150+ C&I sites around Australia - that can respond in real-time when needed by the power grid.  Businesses that participate earn a significant new revenue stream that improves their bottom line.


The Enel X VPP has grown rapidly, and it is now the third largest supplier in the FCAS contingency raise markets. Our VPP represents 90% of the C&I aggregated load in the markets today. With our track record, we are positioned to supply more than 30% of the total market need 1 and expect to become the largest supplier of FCAS reserves 2.

Our FCAS success

Our success is built on a few fundamental competitive advantages:

  1. First, VPPs are built from existing industrial equipment (pumps, compressors, fans, etc.).  This means they can be built quickly, and with a low capital investment per MW of capacity.  
  2. In addition, VPPs can respond faster than traditional power stations, which means that the capacity they offer is more valuable in the FCAS market.


This success comes at a critical time for the power grid in Australia, with the Australian Energy Market Operator (AEMO) and others stating that there is an urgent need for new forms of capacity on the power grid.


"Energy markets must be redesigned to allow for the greatest amount of participation by both demand and supply resources as soon as possible, and begin to pay more accurately for the firming capability and other services we need to keep the system intact."


In this environment, there is understandably a lot of discussion and excitement around the potential for energy storage, and there is no doubt that storage will have to play a critical role in ensuring that we can absorb and utilise growing amounts of renewable power.  We will need GWs of such ‘load shifting’ capacity, and storage (in one form or another) is a key part of the solution.

However, we believe that many are underestimating the impact that VPPs will have on the market.  With their proven and growing success in FCAS, commercial and industrial VPPs have shown that they can deliver critical services to the power grid, quickly and at a large scale.


Enel X manages the largest VPP in Australia today3.  As Australia accelerates its transition to renewable power, we are committed to growing the contribution of VPPs to the power grid because we believe that large-scale VPPs are critical to achieving a cost-effective renewable future.
