NPRR1043  Clarification of NPRR986 Language Related to Wholesale Storage Load

This Nodal Protocol Revision Request (NPRR) provides necessary clarification regarding Settlement of Energy Storage Resources (ESRs) as developed in NPRR986, BESTF-2 Energy Storage Resource Energy Offer Curves, Pricing, Dispatch, and Mitigation, which received ERCOT Board approval on February 11, 2020, and is currently in the early phase of development. Specifically, this NPRR clarifies that the charging Load (excluding auxiliary Load) withdrawn by an ESR shall be settled based on the nodal price, similar to its injections, even if the ESR does not seek or cannot qualify for Wholesale Storage Load (WSL) treatment. It does so by replacing the term “ESR Load that is not WSL,” which appears in several places in the original NPRR986 language, replacing that term with a defined term, “Non-WSL ESR Charging Load.” The Non-WSL ESR Charging Load will be priced at nodal but, unlike ESRs receiving WSL treatment, will be subject to applicable Load Ratio Share (LRS)-based charges.
