Battery operators under ERCOT forfeited approximately 32% of their potential earnings in the year 2023

In the heart of Texas, the Electric Reliability Council of Texas (ERCOT) market is grappling with an issue that's causing ripples in the energy sector. The market, it seems, does not adequately incentivize the ancillary revenue stream for batteries.

This observation is not without basis. The framework for managing batteries within ERCOT is not being used effectively, leading to a situation where taking very little risk in managing a battery can result in making quite a lot of money. However, the risk in managing a battery is not well accounted for among the batteries in ERCOT, creating a risk-return trade-off that operators must navigate carefully.

The current market framework does not seem to be sufficiently incentivizing the ancillary revenue stream for batteries in ERCOT. A lower-revenue battery, for instance, could potentially double its monthly revenue by incorporating a diversified mix of ancillary services.

The strategy that's reaping rewards for some operators involves bidding large quantities of ERCOT Contingency Reserve Services, a new ancillary service product released last June. Those who have adopted this approach have achieved significantly higher monthly revenues. Operators that hit the top tiers of revenue with this strategy either forecasted state of charge demands or bid aggressively on the new service.

The concept of risk in managing a battery is not well accounted for in the ERCOT market. Companies offering optimization platforms for battery storage automation in Texas, such as Gridmatic, Fluence, and Stem, are working to address this issue. Tesla, based in Austin, is another key player, manufacturing and operating battery storage solutions like Powerwall, Powerpack, and Megapack, complete with integrated software for storage management.

Incorporating a diversified mix of ancillary services can potentially increase a battery's monthly revenue. As the market evolves, it's clear that a more balanced approach to incentivizing ancillary revenue streams for batteries will be crucial for the continued success of the ERCOT market and the energy sector as a whole.
