Interconnection Customer and Idaho Power each may be referred to as a “Party” or collectively as the “Parties.” WITNESSETH: WHEREAS, on February 12, 2020, Idaho Power and Franklin Solar LLC, entered into an LGIA (“Franklin Solar #549”); WHEREAS, on April 12, 2022, Idaho Power and Franklin Solar LLC entered into a First Amendment to the LGIA (“First Amendment”) to incorporate the changes identified in a re- study process precipitated by configuration changes made by a senior-queued project that impacted the configuration of Franklin Solar #549. This amendment also included adding a 20 MW battery energy storage system to the 100 MW solar project with the total output at the POI continuing to be limited to 100 MW; WHEREAS, on October 6, 2022, Franklin Solar LLC submitted a material modification evaluation request to Idaho Power, which consisted of a proposal to update the existing 20 MW BESS to 60 MW BESS. The total output at the POI would continue to be limited to 100 MW; WHEREAS, Idaho Power performed an assessment of the BESS increase from 20 MW to 60 MW and determined that the modification is not considered a material modification. The proposed changes do not result in any new reliability concerns nor do they require additional facilities beyond what was previously identified in the First Amendment; WHEREAS, on October 20, 2022, Franklin Solar LLC formally requested a GIA amendment to incorporate the BESS increase from 20 MW to 60 MW; WHEREAS, on November 8, 2022, Idaho Power received notification that Franklin Solar LLC assigned the LGIA, as amended by the First Amendment, to an Affiliate, Franklin Interconnection, LLC, and that such Affiliate meets the requirements with respect to such assignment set forth in Section 19.1 of the February 12, 2020 LGIA; WHEREAS, the assignment resulted in a change to the Interconnection Customer information provided in Appendix F of the LGIA, as amended by the First Amendment; Response to Staff Request No. 70 - Attachment 3 DocuSign Envelope ID: C846F6A2-5FD6-40BD-AA5A-71598030E0AB November 22, 2022 Delaware Second Amendment to LGIA Idaho Power Company GI Queue #549 Franklin Solar Page 2 WHEREAS, Idaho Power acknowledges and accepts the reassignment of the LGIA, as amended by the First Amendment, from Franklin Solar LLC to Franklin Interconnection, LLC; and WHEREAS, the Parties now desire to amend the LGIA by executing this Second Amendment to the LGIA to acknowledge the Interconnection Customer reassignment and incorporate the BESS increase from 20 MW to 60 MW. NOW, THEREFORE, the Parties, intending to be legally bound, agree as follows: 1.Recitals. The Parties acknowledge and agree as to the accuracy of the Recitals set forth above, and such Recitals are incorporated herein by reference. 2.Amendment to Agreement. The Parties hereby agree to amend the February 12, 2020, LGIA and First Amendment to incorporate Exhibits A, B, and C, attached hereto and fully incorporated herein by this reference. Exhibit A—Updated General Facility Description in Appendix A to LGIA Exhibit B—Updated Interconnection Customer Generating Facilities in Appendix C to LGIA Exhibit C—Updated Appendix F to LGIA 3. Effect of Amendment. Except as expressly amended by this Second Amendment, the LGIA and First Amendment shall remain in full force and effect. 4. Capitalized Terms. All capitalized terms used in this Second Amendment and not defined herein shall have the same meaning as used in Idaho Power’s Open Access Transmission Tariff. 5. Scope of Amendment. This Second Amendment shall be binding upon and inure to the benefit of the Parties hereto, and their respective heirs, executors, administrators, successors, and assigns, who are obligated to take any action which may be necessary or proper to carry out the purpose and intent thereof. 6.

Load Serving Operations 11/22/2022 11/22/2022 Second Amendment to LGIA Idaho Power Company GI Queue #549 Franklin Solar Page 4 Exhibit A Updated General Facility Description in Appendix A to LGIA General Facility Description The Franklin Solar #549 project will consist of 100 MW photovoltaic and 60 MW battery energy storage system (BESS) installation in Twin Falls County, Idaho and connect to the 345kV system at Idaho Power Company’s (IPC) Rogerson Switching Station on the Midpoint– Humboldt transmission line. The total project output as studied is 100 MW. The Interconnection Customer’s Interconnection Facilities are located approximately ¾ mile to the northwest from IPC’s Interconnection Facilities. The Interconnection Customer will install disconnect switches, distribution collector system(s), transformers (including a main step-up transformer), controllers, appropriate grounding measures, and associated auxiliary equipment. The main step-up transformer is a 67/89.3/111.7 MVA, 3-phase, 345/34.5kV wye-grounded/ wye-grounded with a delta tertiary and should provide adequate ground source for transmission line protection. Interconnection Customer will build 345kV transmission facilities to the Point of Change of Ownership.

The photovoltaic inverter system will comprise of 35 SunGrow SG3150U inverters, with each inverter having an apparent power rating of 3,150 kVA. 2. 35 photovoltaic inverter stations will each comprise of one utility inverter and a 3,150 KVA isolating transformer with a 630V grounded-wye to 34.5kV delta rating. 3. The BESS inverter system will comprise of 19 SunGrow SG3600UD inverters, with each inverter having an apparent power rating of 3,600 kVA. 4. 19 BESS inverter stations will each comprise of one utility inverter and a 3,600 KVA isolating transformer with a 630V grounded-wye to 34.5kV delta rating. 5. A plant controller will be used to control the inverter system and to implement smart inverter functionality for operating the project within a voltage range and power factor specified by IPC at the POI. The above referenced inverters, or equivalent inverters that have the same specifications and functionality as stated above must be utilized. If an inverter is utilized that has different specifications and functionality than that which was studied, then additional study and/or equipment may be necessary. The Project is a combined solar and BESS generation project. It has been assumed the BESS will be charged via the solar output. The Interconnection Customer will need to demonstrate the control measures which prevents the BESS from being charged via IPC’s transmission system.
