* The LLT resource requirements are equally divided among long-duration storage and firm, zero-emitting generation resources.
SDG&E has a preference for projects at or around the NQC of the above targets, but will accept and consider offers for larger projects pursuant to the evaluation process described below.
Table 3, below, shows the Commission approved incremental effective load carrying capacity (“ELCC”) values that will be applied to resources’ nameplate capacities to calculate the NQC for offers intended to count towards SDG&E’s MTR requirements shown in Table 1 above. September NQC was determined by utilizing the Incremental ELCC Study for Mid-term Reliability Procurement by E3 and Astrape and updated in January 2023, at https://www.cpuc.ca.gov/-/media/cpuc-website/divisions/energy-division/documents/integrated-resource-plan-and-long-term-procurement-plan-irp-ltpp/20230210_irp_e3_astrape_updated_incremental_elcc_study.pdf.
