Application 1.1 Applicability These Small Generator Interconnection Procedures ( SGIP ) govern requests to interconnect generating facilities with no more than 20 MW generating capacity to the SRP System Capitalized terms used herein shall have the meanings specified in the body of these procedures, the Transmission Provider s Tariff or in the Large Generator Interconnection Procedures at Attachment O to Transmission Provider s Tariff. Where terms conflict the definitions in this SGIP shall prevail Neither these procedures nor the requirements included hereunder apply to Small Generating Facilities interconnected or approved for interconnection prior to 60 Business Days after the effective date of these procedures Prior to submitting its Interconnection Request (Attachment 2), the Interconnection Customer may ask the Transmission Provider's interconnection contact employee or office whether the proposed interconnection is subject to these procedures. The Transmission Provider shall respond within 15 Business Days Infrastructure security of electric system equipment and operations and control hardware and software is essential to ensure day-to-day reliability and operational security. Transmission Providers, market participants, and Interconnection Customers interconnected with electric systems are expected to comply with the recommendations offered by the President's Critical Infrastructure Protection Board, Good Utility Practices, and standards for electric system infrastructure and operational security, including physical, operational, and cyber-security practices, as such may be modified from time to time References in these procedures to interconnection agreement are to the Small Generator Interconnection Agreement ( SGIA ), a part of the Transmission Provider s Tariff Neither an Interconnection Request nor a completed SGIA confer any transmission or distribution service. Any such transmission or distribution service

5 Improvement and Power District First Revised Sheet No. P-5 must be applied for separately as provided for under the Transmission Provider s Tariff or applicable distribution service rules and regulations. 1.2 Pre-Application The Transmission Provider shall designate an employee or office from which information on the application process and on an Affected System can be obtained through informal requests from the Interconnection Customer presenting a proposed project for a specific site. The name, telephone number, and address of such contact employee or office shall be made available on the Transmission Provider's Internet web site. Electric system information provided to the Interconnection Customer should include relevant system studies, interconnection studies, and other materials useful to an understanding of an interconnection at a particular point on the Transmission Provider's Transmission System, to the extent such provision does not violate confidentiality provisions of prior agreements or critical infrastructure requirements. The Transmission Provider shall comply with reasonable requests for such information. 1.3 Interconnection Request The Interconnection Customer shall submit its Interconnection Request to the Transmission Provider, together with the deposit of $50,000, of which $5,000 is nonrefundable. The Interconnection Request shall be date- and time-stamped upon receipt. The original date- and time-stamp applied to the Interconnection Request at the time of its original submission shall be accepted as the qualifying date- and time-stamp for the purposes of any timetable in these procedures. The Interconnection Customer shall be notified of receipt by the Transmission Provider within five Business Days of receiving the Interconnection Request. The Transmission Provider shall notify the Interconnection Customer within ten Business Days of the receipt of the Interconnection Request as to whether the Interconnection Request is complete or incomplete. If the Interconnection Request is incomplete, the Transmission Provider shall provide along with the notice that the Interconnection Request is incomplete, a written list detailing all information that must be provided to complete the Interconnection Request. The Interconnection Customer will have ten Business Days after receipt of the notice to submit the listed information or to request an extension of time to provide such information. If the Interconnection Customer does not provide the listed information or a request for an extension of time within the deadline, the Interconnection Request will be deemed withdrawn. An Interconnection Request will be deemed complete upon submission of the listed information to the Transmission Provider. 1.4 Modification of the Interconnection Request Modifications are governed by the provisions in the, including, without limitation, those set forth in Sections 4.4 of the LGIP.

6 Improvement and Power District First Revised Sheet No. P Site Control Documentation of site control must be submitted with the Interconnection Request. Site control may be demonstrated through: Ownership of, a leasehold interest in, or a right to develop a site for the purpose of constructing the Small Generating Facility; An option to purchase or acquire a leasehold site for such purpose; An exclusivity or other business relationship between the Interconnection Customer and the entity having the right to sell, lease, or grant the Interconnection Customer the right to possess or occupy a site for such purpose Posting of additional non-refundable deposit of $5,000, which shall be applied to costs of processing the request under this SGIP or otherwise non-refundable if the request is terminated. 1.6 Queue Position The Transmission Provider shall assign a Queue Position based upon the date- and time-stamp of the Interconnection Request. The Queue Position of each Interconnection Request will be used to determine the cost responsibility for the Upgrades necessary to accommodate the interconnection. The Transmission Provider shall maintain a single queue. At the Transmission Provider's option, Interconnection Requests may be studied serially or in clusters for the purpose of the system impact study. 1.7 Interconnection Requests Submitted Prior to the Effective Date of the SGIP Nothing in this SGIP affects an Interconnection Customer's Queue Position assigned before the effective date of this SGIP. The Parties agree to complete work on any interconnection study agreement executed prior to the effective date of this SGIP in accordance with the terms and conditions of that interconnection study agreement. Any new studies or other additional work will be completed pursuant to this SGIP. Section 2. Fast Track Process 2.1 Applicability The Fast Track Process may be available to an Interconnection Customer proposing to interconnect its Small Generating Facility with the Transmission Provider's Transmission System if the Small Generating Facility is no larger than 5 MW. The SGIP Fast Track Process includes a fact-specific evaluation of an interconnection request that may allow Transmission Provider to grant waivers from relevant procedures, steps and/or studies under the SGIP, shortened time frames for relevant procedures, steps and/or studies under the SGIP and expedited tender of an SGIA. Evaluation of an interconnection request under the Fast Track Process is not a guarantee of any waived, abbreviated, or expedited procedures, steps and/or studies under the SGIP nor is it a guarantee of expedited tender by Transmission Provider of an SGIA inasmuch as all aspects of the Fast Track Process are fact-specific and subject to influence by other Interconnection Requests in the Transmission Provider s and all Affected Systems interconnection queues.

7 Improvement and Power District First Revised Sheet No. P Initial Review Using best efforts, within 15 Business Days after the Transmission Provider notifies the Interconnection Customer it has received a complete Interconnection Request, the Transmission Provider shall perform an initial review considering the applicable screens and configuration characteristics set forth below and additional information contained in the interconnection request, Transmission Provider s current interconnection queue and Affected Systems interconnection queues, to preliminarily determine eligibility of the requested interconnection for the Fast Track Process. Transmission Provider shall notify the Interconnection Customer of the results of the initial review, and include with the notification copies of the analysis and data underlying the Transmission Provider's determinations under the screens. If the Transmission Provider requires additional time to complete this work, it will notify the Interconnection Customer of the date by which initial review results and copies of the analysis and data used in the initial review screens will be provided Screens and Configuration Characteristics The proposed Small Generating Facility s Point of Interconnection must be on a portion of the Transmission Provider s electric system that is subject to the Tariff, i.e., electric facilities equal to or greater than 69 kv For interconnection of a proposed Small Generating Facility to a radial distribution circuit, the aggregated generation, including the proposed Small Generating Facility, on the circuit shall not exceed 15 % of the line section annual peak load as most recently measured at the substation and forecasted future planned and expected load. A line section is that portion of a Transmission Provider s electric system connected to a customer bounded by automatic sectionalizing devices or the end of the distribution line The proposed Small Generating Facility, in aggregation with other generation on the distribution circuit, shall not contribute more than 10 % to the distribution circuit's maximum fault current at the point on the high voltage (primary) level nearest the proposed Point of Interconnection.

8 Improvement and Power District First Revised Sheet No. P The proposed Small Generating Facility, in aggregate with other generation on the distribution circuit, shall not cause any distribution protective devices and equipment (including, but not limited to, substation breakers, fuse cutouts, and line reclosers), or Interconnection Customer equipment on the system to exceed 87.5 % of the short circuit interrupting capability; nor shall the interconnection be proposed for a circuit that already exceeds 87.5 % of the short circuit interrupting capability Type of interconnection to a primary distribution line (three-phase, three wire versus three-phase, four wire; three-phase or single phase, phase-to-phase or three-phase or single-phase line-toneutral). This screen includes a review of the type of electrical service provided to the Interconnection Customer, including line configuration and the transformer connection to limit the potential for creating over-voltages on the Transmission Provider's electric power system due to a loss of ground during the operating time of any anti-islanding function If the proposed Small Generating Facility is to be interconnected on single-phase shared secondary, the aggregate generation capacity on the shared secondary, including the proposed Small Generating Facility, shall not exceed 20 kw If the proposed Small Generating Facility is single-phase and is to be interconnected on a center tap neutral of a 240 volt service, its addition shall not create an imbalance between the two sides of the 240 volt service of more than 20 % of the nameplate rating of the service transformer The Small Generating Facility, in aggregate with other generation interconnected to the transmission side of a substation transformer feeding the circuit where the Small Generating Facility proposes to interconnect shall not exceed 10 MW in an area where there are known, or posted, transient stability limitations to generating units located in the general electrical vicinity (e.g., three or four transmission busses from the point of interconnection)

Load Flow and Dynamic Models (this data should be provided electronically as instructed by SRP). Provide load flow model for the generating plant and its interconnection facilities in GE PSLF *.epc format, including new buses, generators, transformers, interconnection facilities. An equivalent model is required for the plant with generation collector systems. This data should reflect the technical data provided in this Appendix B. For inverter based generating facilities, select the appropriate generator and control models from the General Electric PSLF Program Manual and provide the required input data. Please note, a completed *.dyd file that contains the information specified in this section will be needed prior to performing the Interconnection System Impact Study. However, a *.dyd file is not required at the time of the Interconnection Request. If you require assistance in developing the models, we suggest you contact General Electric. Accurate models are important to obtain accurate study results. Costs associated with any changes in facility requirements that are due to differences between model data provided by the generation developer and the actual generator test data, may be the responsibility of the generation developer.

The Transmission Provider reserves the right to request additional technical information from the Interconnection Customer as may reasonably become necessary consistent with Good Utility Practice during the course of the feasibility study and as designated in accordance with the Small Generator Interconnection Procedures. If the Interconnection Customer modifies its Interconnection Request, the time to complete the feasibility study may be extended by agreement of the Parties or as reasonably determined by the Transmission Provider. 5.0 In performing the study, the Transmission Provider shall rely, to the extent reasonably practicable, on existing studies of recent vintage. The Interconnection Customer shall not be charged for such existing studies; however, the Interconnection Customer shall be responsible for charges associated with any new study or modifications to existing studies that are reasonably necessary to perform the feasibility study. 6.0 The feasibility study report shall provide the following analyses for the purpose of identifying any potential adverse system impacts that would result from the interconnection of the Small Generating Facility as proposed: 6.1 Initial identification of any circuit breaker short circuit capability limits exceeded as a result of the interconnection; 6.2 Initial identification of any thermal overload or voltage limit violations resulting from the interconnection; 6.3 Initial review of grounding requirements and electric system protection; and 6.4 Description and non-binding estimated cost of facilities required to interconnect the proposed Small Generating Facility and to address the identified short circuit and power flow issues. 7.0 The feasibility study shall model the impact of the Small Generating Facility regardless of purpose in order to avoid the further expense and interruption of operation for reexamination of feasibility and impacts if the Interconnection Customer later changes the purpose for which the Small Generating Facility is being installed. 8.0 The feasibility study shall include the feasibility of one or more potential Points of Interconnection, as requested by the Interconnection Customer and at the Interconnection Customer's cost. 9.0 Transmission Provider will utilize the Interconnection Customer s deposit associated with the Interconnection Request. If the deposit is not sufficient to cover the estimated costs of the study, an additional deposit sufficient to cover the total good faith estimated feasibility study costs is required from the Interconnection Customer and must be provided to the Transmission Provider with the executed feasibility study agreement. During the study, Transmission Provider will notify Interconnection Customer if Transmission Provider expects the study costs to exceed the estimated costs. Transmission Provider will invoice Interconnection Customer for the estimated additional funds needed to perform and complete the study. Upon completion of the study work, Transmission Provider will provide a final accounting to Interconnection Customer, and will render a refund, if and as needed, for any difference between the total payments advanced by Interconnection Customer and the total amount of actual study costs incurred by Transmission Provider.
