Background

Status: Approved
Date Posted: Jul 16, 2019
Sponsor: Boston Energy Trading and Marketing
Urgent: No
Sections: 2.1, 2.2, 3.8, 3.8.6 (new), 6.5.5.2, and 16.5
Description: This Nodal Protocol Revision Request (NPRR):establishes the terms “Energy Storage System” (ESS) and “Energy Storage Resource” (ESR), with ESS serving as an “umbrella term” for storage assets in general, and ESR corresponding to ESSs that are eligible to participate in Security-Constrained Economic Dispatch (SCED) and/or provide Ancillary Services; adds new Section 3.8.6 to clarify that the Resource Entity and Qualified Scheduling Entity (QSE) representing an ESR are responsible for following all requirements associated with Generation Resources and Controllable Load Resources. Under this process, an ESR must be registered with ERCOT as both a Generation Resource and a Controllable Load Resource; adds new paragraph (12) to Section 6.5.5.2 to specify telemetry requirements unique to ESRs; and adds new paragraph (6) to Section 16.5 to provide greater transparency of ERCOT’s current practice of requiring a Resource Entity to register an ESR as both a Generation Resource and a Controllable Load Resource. ERCOT expects that this dual-registration requirement may be superseded by future requirements and system changes that facilitate participation by an ESR as a single asset.
Reason: Addresses current operational issues. Market efficiencies or enhancements.
