The Honorable Kimberly D. Bose Secretary Federal Energy Regulatory Commission 888 First Street NE Washington, DC 20426

RE: Southwest Power Pool, Inc., Docket No. ER18-______Submission of Interconnection Agreement

Dear Secretary Bose:

Pursuant to section 205 of the , 16 U.S.C. § 824d, Southwest Power Pool, Inc. (“SPP”) encloses for filing an executed interconnection agreement between Western Area Power Administration (“WAPA”) and Great River Energy (“Great River”) with Midcontinent Independent System Operator, Inc. (“MISO”) and SPP as signatories (“Interconnection Agreement”).1 SPP requests that the Federal Energy Regulatory Commission (“Commission”) accept the proposed Interconnection Agreement with an effective date of April 27, 2018. In support, SPP states the following:

I. Background

SPP is a Commission-approved Regional Transmission Organization (“RTO”). SPP is an Arkansas non-profit corporation with its principal place of business in Little Rock, Arkansas. SPP currently has 98 members including 16 investor-owned utilities, 14 municipal systems, 20 generation and transmission cooperatives, 8 state agencies, 15 independent power producers, 12 power marketers, 11 independent transmission companies, 1 federal agency, and 1 large retail customer. As an RTO, SPP is a transmission provider administering transmission service over portions of Arkansas, Iowa, Kansas, Louisiana, , Missouri, Montana, Nebraska, New Mexico, North

1 WAPA and Great River may be referred to individually as “Party” or collectively as “the Parties.” The Interconnection Agreement is designated by SPP as Original Service Agreement No. 3458. The Interconnection Agreement is being filed separately by both SPP and MISO in their respective eTariff systems. The Interconnection Agreement is designated by MISO as Original Service Agreement No. 3133.

The Honorable Kimberly D. Bose August 1, 2018 Page 2

Dakota, Oklahoma, South Dakota, Texas and Wyoming. SPP is responsible for providing independent transmission services over the transmission facilities its members have placed under the SPP Open Access Transmission Tariff (“SPP Tariff”).2

WAPA is a Federal power marketing agency that markets Federal power and owns and operates transmission facilities throughout 15 western and central states, encompassing a geographic area of 1.3 million square miles. Western was established pursuant to section 302 of the Department of Energy Organization Act.3 WAPA is a transmission owning member of SPP and has transferred functional control of its transmission system to SPP. Great River is a cooperative corporation organized in the state of Minnesota.

The Parties entered into the Interconnection Agreement to facilitate the interconnection of their respective transmission systems. Consistent with the Commission’s policy that the RTO with the planning authority over transmission facilities under its Tariff (i.e., SPP) should be a signatory to interconnection agreements, SPP is a signatory to the Interconnection Agreement.4

1. APPLICABILITY: These General Interconnection Contract Provisions (Provisions) shall be a part of the contract to which they are attached. In the event these Provisions differ from requirements of the contract, specific terms set forth in the contract shall prevail.

2. CHARACTER OF SERVICE: Electric energy supplied or transmitted under the contract, if any, and interconnected systems will be three-phase, alternating current, at a nominal frequency of sixty (60) hertz (cycles per second).

3. CONTINUITY OF SERVICE: Interconnection service will be provided continuously, pursuant to the provisions of the contract, except for: (1) fluctuations, interruptions, or reductions due to uncontrollable forces, as defined in Provision 22 (Uncontrollable Forces) herein, (2) fluctuations, interruptions, or reductions due to operation of devices installed for ; and (3) temporary fluctuations, interruptions, or reductions, which, in the opinion of the party supplying the service, are necessary or desirable for the purposes of maintenance, repairs, replacements, installation of equipment, or investigation and inspection. The party supplying service, except in case of emergency, will give the party to whom service is being provided reasonable advance notice of such temporary interruptions or reductions and will remove the cause thereof with diligence.

4. METERING:

4.1 The total electric power and energy supplied or transmitted under the contract, if any, will be measured by metering equipment to be furnished and maintained by Western, a designated representative of Western, or where situations deem it appropriate as determined by Western, by the Contractor or its agent(s). In the event metering equipment is furnished and maintained by the Contractor or its agent(s) and the equipment is used for billing and other accounting purposes by Western, the Contractor shall ensure that the metering equipment complies with applicable metering policies established by Western.

4.2 Meters shall be secured by appropriate security measures and meters shall not be accessed except when the meters are to be inspected, tested, adjusted, or repaired. Representatives of affected parties shall be afforded reasonable opportunity to be present upon such occasions. Metering equipment shall be inspected and tested each year by the party responsible for meter maintenance, unless a different test interval is determined in accordance with good utility practices by an applicable regional metering policy, or as agreed upon by the parties. Meters shall also be tested at any reasonable time upon request by a party hereto, or by an affected supplemental power supplier, transmission agent, or control area operator. Any metering equipment found to be damaged, defective, or inaccurate shall be repaired and readjusted or replaced by the party responsible for meter maintenance as soon as practicable. Meters found with security breaches shall be tested for tampering and, if appropriate, meter readings shall be adjusted by Western pursuant to Provision 4.3 below.

1

4.3 Except as otherwise provided in Provision 4.4 hereof, should any meter that is used by Western for billing or other accounting purposes fail to register accurately, the electric power and energy supplied or transmitted during the period of failure to register accurately, shall, for billing purposes, be estimated by Western from the best available information.

4.4 If inspections and tests of a meter used by Western for billing or other accounting purposes disclose an error exceeding 2 percent, or a lesser range in error as agreed upon by the parties, then a correction based upon the inaccuracy found shall be made to the service records for the period of inaccuracy as determined by Western. If the period of inaccuracy cannot be determined, the inaccuracy shall be assumed to have existed during the entire monthly billing period immediately preceding the billing period in which the inspection or test was made and the resulting correction shall be made accordingly.

4.5 Any correction in billing or other accounting information that results from a correction in meter records shall be made in a subsequent monthly bill rendered by Western to Contractor. Payment of such bill shall constitute full adjustment of any claim between the parties arising out of inaccurate metering equipment.

5. CONSTRUCTION, OPERATION, AND MAINTENANCE OF POWER SYSTEMS:

5.1 Contractor’s Power System: The Contractor shall, and, if applicable, shall require each of its members or transmission agents to construct, operate, and maintain its power system in a manner which, as determined by Western, will not interfere with the operation of the system of Western or its transmission agents over which electric services are furnished to the Contractor under the contract, and in a manner which will coordinate with the protective relaying and other protective arrangements of the system(s) of Western or Western’s transmission agents. Western may reduce or discontinue furnishing services to the Contractor if, after notice by Western, the Contractor fails or refuses to make such changes as may be necessary to eliminate an unsatisfactory condition on the Contractor’s power system which is determined by Western to interfere significantly under current or probable conditions with any service supplied from the power system of Western or from the power system of a transmission agent of Western. Such a reduction or discontinuance of service will not relieve the Contractor of liability for any minimum charges provided for in the contract during the time said services are reduced or discontinued. Nothing in this Provision shall be construed to render Western liable in any manner for any claims, demands, costs, losses, causes of action, damages, or liability of any kind or nature arising out of or resulting from the construction, operation, or maintenance of the Contractor’s power system.

5.2 Western’s Power System: Western shall construct, operate, and maintain its power system in a manner which, as determined by the Contractor, will not interfere with the operation of the system of the Contractor over which services are furnished to Western

2

under the contract, and in a manner which will coordinate with the protective relaying and other protective arrangements of the system of the Contractor. The Contractor may reduce or discontinue furnishing services to Western if, after notice by the Contractor, Western fails or refuses to make such changes as may be necessary to eliminate an unsatisfactory condition on Western’s power system which is determined by the Contractor to interfere significantly under current or probable conditions with any service supplied from the power system of the Contractor or from the power system. Such a reduction or discontinuance of service will not relieve Western of liability for any minimum charges provided for in the contract during the time said services are reduced or discontinued. Nothing in this Provision shall be construed to render the Contractor liable in any manner for any claims, demands, costs, losses, causes of action, damages, or liability of any kind or nature arising out of or resulting from the construction, operation, or maintenance of Western’s power system.

6. BILLING AND PAYMENT:

6.1 Payments of bills issued by a party pursuant to this contract are due and payable by the payor by the date specified on the individual bills for collection, which shall be not sooner than twenty (20) calendar days from the date of issuance, or the next business day thereafter if said day is a Saturday, Sunday, or Federal holiday. Bills shall be considered paid when payment is received by issuing party. Bills will be paid electronically or via the Automated Clearing House method of payment unless a written request to make payments by mail is agreed upon by the parties. Should the parties agree to accept payments by mail, these payments will be accepted as timely and without assessment of the charge provided for in Provision 6.3 if a United States Post Office first class mail postmark indicates the payment was mailed at least three (3) calendar days before the due date.

6.2 The parties agree that net billing procedures will be used for payments due Western by the Contractor and for payments due the Contractor by Western for the sale or exchange of electric power and energy, use of transmission facilities, operation and maintenance of electric facilities, and other services. Payments due one party in any month shall be offset against payments due the other party in such month, and the resulting net balance shall be paid to the party in whose favor such balance exists. The parties shall exchange such reports and information that either party requires for billing purposes. Net billing shall not be used for any amounts due which are in dispute.

6.3 Bills not paid in full by the Contractor by the due date specified on the individual bills for collection shall bear a charge of five hundredths percent (0.05%) of the principal sum unpaid for each day payment is delinquent, to be added until the amount due is paid in full. Western will also assess a fee of twenty-five dollars ($25.00) for processing a late payment. Payments received will first be applied to the charges for late payment assessed on the principal and then to payment of the principal. Western will make payments, including any interest for late payments, in accordance with the Prompt Payment Act, 31 U.S.C. §§ 3901-3907, as amended or supplemented.

6.4 The billing party shall have the right, upon not less than fifteen (15) business days advance written notice, to suspend furnishing the services specified in the contract for nonpayment of bills in full when due, and to refuse to resume such services so long as any part of the amount due remains unpaid. Such a suspension of service will not relieve the delinquent party of liability for minimum charges during the time service is so suspended. The rights reserved herein shall be in addition to all other remedies available to the parties either by law or in equity, for the breach of any of the terms hereof.

7. DESIGN APPROVAL:
