More than a decade ago, ERCOT convened the Future Ancillary Services Team (FAST) to prepare for the kind of incident that hit Spain this week (I’ve been doing this long enough that I participated in some of those meetings). That effort led to a new fast-responding backup reserve program that helps ERCOT deal with rapid frequency shifts.

The article discusses Texas's preparedness for rapid frequency deviations in its power grid, particularly in light of a recent incident in Spain. It highlights the proactive measures taken by ERCOT, including the establishment of the Future Ancillary Services Team (FAST) and the implementation of a Fast Frequency Regulation (FFR) program, which allows for rapid response to frequency fluctuations. Texas boasts a significant advantage over Spain with its extensive battery energy storage systems, enabling quicker responses to grid disturbances.

Furthermore, the article emphasizes the importance of a comprehensive approach to grid management, termed 'Defense-in-Depth,' which encompasses various ancillary services to address multiple risks. It stresses the need for continuous improvement and adaptation in response to new energy sources and potential challenges. The author advocates for the expansion of fast-acting resources, particularly batteries, to enhance grid reliability and support Texas's leadership in renewable energy while ensuring affordability and stability.
