NPRR1038  BESTF-8 Limited Exemption from Reactive Power Requirements for Certain Energy Storage Resources

This Nodal Protocol Revision Request (NPRR) establishes a limited exemption from Reactive Power requirements for certain Energy Storage Resources (ESRs). The exemption is available only to an ESR that achieved Initial Synchronization prior to December 16, 2019 (the date NPRR989, BESTF-1 Energy Storage Resource Technical Requirements, was submitted) and applies only to the extent the ESR is unable to comply with the Reactive Power requirements when it is charging. In order to qualify for the exemption, the Resource Entity for the ESR must submit a notarized attestation to ERCOT stating that the ESR would be unable to comply with the Reactive Power requirements without making physical or software changes. The NPRR does not exempt any ESR from the responsibility to provide Reactive Power when discharging.
