*The LLT resource requirements are equally divided among long-duration storage and firm, zero-emitting generation resources.
**The zero-emitting resources required to replace Diablo Canyon must be procured by 2025, but may occur in any of the years 2023-2025; therefore, the columns do not add to the total.
To meet the requirements, SDG&E seeks to execute agreements for projects that qualify as LLT resources that have the following characteristics:
- Generation capacity that has no on-site emissions or is eligible under the requirements of the renewables portfolio standard program and has at least an 80 percent capacity factor. The resource must not be use limited or weather dependent. No storage projects shall qualify under this provision.
SDG&E will consider offers to meet the June 1, 2028, firm, zero emitting resource requirements, in the capacity targets discussed in Table 1, above. For this requirement, SDG&E will accept and consider offers for projects that have, at a minimum, expected online dates of as discussed above no later than June 1, 2031, but will give priority to offers for projects with expected online dates by June 1, 2028.
Firm, zero-emitting resources must be generation capacity that has no on-site emissions or is eligible under the requirements of the Renewables Portfolio Standard program and has at least an 80 percent capacity factor. The resource must not be use limited or weather dependent. No storage projects shall qualify under this provision. Additional resource requirements are set forth later in this Protocol.
