Comments of the ESA re: ERCOT Future Ancillary Services Team (FAST) Draft Nodel Protocol Revision Request

Posted: October 15, 2014 - 17:00 / ERCOT / ESA Filings

The Energy Storage Association (ESA) appreciates the opportunity to comment on the draft Nodal Protocol Revision Request proposed by ERCOT staff. ESA has actively participated in each FAST meeting and provides the following comments which we request be included in the formal Nodal Protocol Revision Request when it is proposed.

As background, the ESA is an industry trade association that was established over 20 years ago to foster the development and commercialization of energy storage technologies. Since then, its mission has been the promotion, development and commercialization of competitive and reliable energy storage delivery systems for use by electricity suppliers and their customers. ESA members represent a diverse group of entities, including electric utilities, energy service companies, independent power producers, technology developers involved with advanced batteries, flywheels, thermal and compressed air energy storage, pumped hydro, supercapacitors and component suppliers, such as power conversion systems. ESA’s members also include researchers who are committed to advancing the state-of-the-art in energy storage solutions.

ESA offers comments on the policy issue surrounding the pricing and procurement of Fast Frequency Response Service and Primary Frequency Response Service. This issue has been the subject of three TAC/FAST workshops and remains a significant issue for the new suite of Ancillary Services. The resolution of this issue will greatly impact the success of the overall FAST process and the ability of new resources like energy storage to enter the ERCOT market.

ESA also offers comments on the specific provisions in the draft NPRR. Some comments focus on oversights and some focus on more substantive deviations from the concepts discussed in the FAST process. Overall, ESA believes the newly structured Ancillary Services have the potential to bring additional efficiency and flexibility to the ERCOT grid, depending on the pricing and procurement methodologies that are ultimately adopted. We look forward to continuing to work with ERCOT and the other stakeholders to create a fair and efficient Ancillary Service market.
