INTERCONNECTION AGREEMENT
BETWEEN
EL PASO ELECTRIC COMPANY
AND
SOUTHWESTERN PUBLIC SERVICE COMPANY


THIS AGREEMENT, made and entered into this 8th day of December, 1981, by and between EL PASO ELECTRIC COMPANY, a Texas corporation, hereinafter referred to as EPE, and SOUTHWESTERN PUBLIC SERVICE COMPANY, A New Mexico corporation, hereinafter referred to as SPS.
W I T N E S S E T H:
WHEREAS, EPE owns and operates an electric utility system, including generation, transmission and distribution facilities, in the States of New Mexico, Texas and Arizona, and SPS owns and operates an electric utility system, including generation, trans­mission and distribution facilities, in the States of Texas, New Mexico, Oklahoma and Kansas, and
WHEREAS, the systems of the parties in New Mexico are so located and constituted that they can be interconnected by means of transmission lines and other facilities, and
WHEREAS, under this agreement certain facilities for the interconnection of the systems of the parties will be installed and placed in operation by the parties, and
WHEREAS, it is indicated that the parties can realize substantial benefits for their customers by the maintenance of such an interconnection and the interchange of power through such inter-




-1-











connection, among such benefits being the following:
		
	a.
	Reduction in the aggregate generating capacity and transmission equipment of the systems of the parties by reason of the parties being able to alternate or defer the installation of generating and transmission facilities with consequent savings in investment capital charges and operating expenses, and


		
	b.
	Better continuity and reliability of service with consequent savings in operating expenses by reason of the parties being able to cooperate with each other in reducing and partially eliminating local and system service interruptions, and


WHEREAS, it is expected that it will he of mutual advantage to the parties from time to time to purchase, sell or exchange electric power and energy from one system to the other under the terms of this Agreement;
NOW, THEREFORE, in consideration of the premises and the covenants and agreements hereinafter set forth, the parties agree as follows:
		
	l.
	SCOPE: The parties shall operate their systems in such a manner that reliability of the total system will be improved, shall maintain reasonable and equit­able reserves and interconnections with other utility systems, and shall cooperate in furnishing through the various points of interconnection of their systems such quantities of electric power and energy as either






-2-









party may request from time to time, in accordance with the terms and conditions set forth herein and the service schedules attached hereto.
		
	2.
	ELECTRIC POWER SYSTEM OF EPE:  Any reference to the electric power system or facilities of EPE shall mean the electric generating and transmission facilities owned and operated by EPE or available to it for the production and transmission of electricity and the interchange of electricity with other electric power systems.


		
	3.
	ELECTRIC POWER SYSTEM OF SPS:  Any reference to the electric power system or facilities of SPS shall mean the electric generating and transmission facilities owned and operated by SPS or available to it for the production and transmission of electricity and the interchange of electricity with other electric power systems.


		
	4.
	POINTS OF INTERCONNECTION AND DELIVERY:  The points of delivery for electric power and energy under this Agreement are described in Exhibit I attached hereto. Additional points of .interconnection and delivery may be established by the parties as additions to Exhibit I.


		
	5.
	FACILITIES TO BE PROVIDED BY EACH PARTY: The facilities to be provided by each party are shown and described in Exhibit II attached hereto.


		
	6.
	USE OF FACILITIES:  Each party shall make available






-3-









its part of the interconnection for interconnected operations.  With the exception of the DC Terminal, each party shall operate and maintain its part of the interconnection at its own expense as required for satisfactory coordinated operation. Each party shall have the right to tap its portion of the interconnection provided that the Operating Committee determines that the tap will not jeopardize the usefulness of the interconnection to any other utility having an interest in the interconnection. The investment in the interconnection shall be the consideration for use of the interconnection by the parties subject to the provisions of this Agreement.
		
	7.
	SERVICE TO BE RENDERED:  Inasmuch as the various specific services to be rendered by each party to the other in furtherance of the purposes of the parties in establishing and maintaining interconnections will vary from time to time during the term hereof, and the terms, arrangements and rates applicable to such services must necessarily depend upon the conditions from time to time existing, it is intended that such services and terms, arrangements and rates applicable thereto will be set forth in Service Schedules which may be formulated between the parties hereto, which Service Schedules when executed by the parties hereto shall become parts






-4-









of this Agreement during the periods fixed by their respective terms.
EPE and SPS recognize that from time to time there may be mutual advantages from the sale or inter­change of power and energy on a basis not provided for in any Service Schedule then in effect, and circumstances may be such that arrangements must be made promptly in order to realize such advantage. In such cases, or in cases of emergency, temporary arrangements for transactions may be made by the Operating Committee, provided, however, that the arrangements shall not extend for more than thirty (30) days unless ratified in writing by an officer representing each of the parties.
		
	8.
	DELIVERY:  All electric energy delivered under this Agreement shall be of the character commonly known as three-phase, sixty hertz energy and shall be delivered at the nominal voltages and the points of delivery as set out in Exhibit I.


		
	9.
	OPERATING COMMITTEE:  The interconnected operations of the parties' systems, as provided for in this Agreement, shall be administered by an Operating Committee consisting of a representative of each of the parties.  Within thirty (30) days after the date this. Agreement is executed, each party shall designate by written notice to the other party the representative






-5-









who will be authorized to act in its behalf on the Operating Committee. A party may change its representative upon written notice to the other party. The principal duties of the Operating Committee shall be as follows:
		
	a.
	To establish operating (normal and emergency), scheduling and control procedures;


		
	b.
	To coordinate maintenance schedules;


		
	c.
	To establish budgeting, accounting and billing procedures; and


		
	d.
	To perform those duties which this Agreement requires to be done by the Operating Committee, and such other duties as may be required for the proper functioning of this Agreement.


If any other electric utility acquires an interest in the interconnection facilities, it shall also have a representative on the Operating Committee. If the Operating Committee is unable to agree on any matter coming under its jurisdiction, it shall within fifteen (15) days thereafter refer the matter in writing to the chief executive officers of the parties. If the chief executive officers are unable to agree on the matter within forty-five (45) days after the referral, either party may submit the matter to arbitration.
		
	10.
	SERVICE CONDITIONS: The systems of the parties shall normally be operated electrically interconnected, ex-






-6-









cept as otherwise from time to time arranged between the parties. Nothing contained herein shall restrict or limit either party in effecting other interconnection agreements or interconnections with other systems.
The parties recognize that difficult operating and technical problems may arise in the con­trol of frequency and in the control of the flow of power over the transmission systems of both parties, and over other interconnections of both of them, and that successful interconnection operation can only be accomplished through the cooperation of their respective operating departments. Such operating departments shall cooperate with each other in attempting to control the frequency and the flow of power from one system to the other interconnected systems so that as nearly as practicable the delivery and receipt of power and energy shall be accomplished, as provided for in this Agreement, consistent with the least interference with any interchange or interconnection agreements which either party may have with other parties.
The parties shall provide on their respective systems, at their own expense, the necessary communication, telemetering and control facilities and shall operate their respective power sources so that uninten-




-7-









tional interchange between the systems of the parties resulting from operation of the systems electrically interconnected shall, insofar as practicable, be kept in balance continuously, and any imbalance at the end of any hourly period shall be carried forward for balancing during a subsequent hourly period; provided, that such balancing shall be accomplished during an hourly period or periods of system conditions similar to the period or periods during which the unintentional interchange occurred, and as prescribed by Operating Guides of the National Electric Reliability Council or other interconnected operating pool groups of which the parties are members.
		
	ll.
	INTERCONNECTION THROUGH OTHER SYSTEMS:  As the parties' systems may be indirectly interconnected, at times, through other systems, it is recognized that because of the physical characteristics of the facilities involved, there may be energy flows through such other systems and part of the energy being transferred from one party to the other party may flow through such other systems rather than through the intended point or points of interconnection.


Power and energy may also flow through the facilities of the parties as a result of the characteristics of their system and of other systems which may be interconnected and be included in the demand and energy




-8-













meter readings. Therefore, the Operating Committee shall determine the methods for ascertaining the amount of through power, and energy, and the actual deliveries of power and energy made both directly and indirectly and the best means to insure deliveries by one party to the other. The parties shall at all times cooperate in the development of any arrangements with other interconnected systems as may be necessary to provide a basis for determining the energy flows between the parties  through the system involved.
		
	12.
	ENERGY LOSSES:  Each party shall supply the energy losses on its own facilities or other facilities if included in its control area.


		
	13.
	METERING: Electric metering for measurement of power and energy delivered and received through any point of interconnection under this contract shall be selected, installed and maintained in accordance with the latest issue of American Standard Code for Electricity Metering.  Metering location and voltage shall be as set forth in Exhibit I.


All electric metering equipment, at the point of interconnection, shall be maintained by the respective owner and shall be tested at least annually by such owner. The owner of the metering equipment shall notify the other party when meters are to be maintained and shall provide a two weeks' notice to the other party




-9-









when meters are to be tested or when changes in metering are to be made, so that the other party may provide a witness to the test or to changes in metering.  After proper notification to the other party, the owner may proceed with the scheduled tests or work regardless of whether a witness is present.
Overall metering accuracy, which includes errors in current and potential transformers and errors in meters, shall be maintained such that error in registration shall not exceed l 1/2 percent. Should an error in registration exceeding l 1/2 percent be found, notice shall be given to the other party and adjustments shall be made in the interchange accounts. Such ad­justments shall apply to the actual period during which such inaccuracy may be determined to have existed, but if the period cannot be determined, the adjustment shall apply to one-half the period since the date of the last test. Should metering equipment fail to register, the power and energy delivered and received shall be determined by agreement of the parties.
		
	14.
	RIGHT OF INSTALLATION:  Each party will make available suitable space for installation of the necessary equip­ment, apparatus and devices required for the performance of this Agreement.


		
	15.
	RIGHT OF REMOVAL: Any and all equipment, apparatus and devices caused to be placed or installed by one






-10-









party on, or in, the premises of the other party shall be and remain the property of the party owning such equipment, apparatus and devices regardless of the mode or manner of annexation or attachment to the premises. Upon the termination of this Agreement each party shall within six (6) months remove all its equipment, apparatus and devices from the pre­mises of the other party, leaving the premises in a good state of repair. All foundations for all equipment shall be removed completely from the premises, or to a lesser degree if agreement for the lesser degree is reached between the parties at the time.
		
	16.
	RATES: EPE shall pay SPS for all power and energy delivered pursuant to this Agreement at the rates and in accordance with the terms set forth in Service Schedules A, B and C attached hereto and incor­porated herein.


		
	17.
	BILLS AND PAYMENTS: All billing shall be based on scheduled transactions and shall be made on or before the seventh day of each calendar month. Payment for all electric power and energy sold hereunder shall be made in accordance with the rate schedules then in effect. If the payment due date falls on a Saturday, Sunday or holiday, the payment shall be due on the business day next following such day.

SERVICE SCHEDULE B ECONOMY ENERGY SERVICE


Section l - Definition - Economy Energy
Economy Energy as used herein shall mean electric energy which one Company (Seller) can produce at an incremental cost which is lower than the incremental cost the other Company (Buyer) would incur by producing and/or procuring equivalent energy from other available sources, and which energy Seller is willing and able to sell and deliver to Buyer.
It is understood and agreed that a Company is entitled to pur­chase Economy Energy only to the extent that such company has alter­nate dependable capacity that could otherwise be used.  Any firm power capacity or unit capacity being purchased by Buyer shall be included in the alternate dependable capacity.
Section 2 - Purchase and Sale of Economy Energy
At any time that one of the Companies (Buyer) desires to pur­chase Economy Energy and another Company (Seller) is willing and able to supply such Economy Energy, the two Companies may effect such purchase and sale under the provisions of this Service Schedule B. Such purchase and sale shall be entirely voluntary on the part of each Company.  The price to be paid by Buyer to Seller for such Economy Energy so agreed upon shall be the price calculated at the time of such agreement in accordance with Section 3 hereof.
If the Companies mutually agree to purchase and sell the specified Economy Energy, then Seller shall furnish the agreed amount of Economy Energy from any source available to it; provided that, if any emergency shall occur on Seller's system so as to




B-1









force Seller to provide energy at a rate higher than the agreed upon selling price for such Economy Energy in order to fulfill the specified Economy Energy commitment to Buyer, Buyer agrees that it will relieve Seller of its obligation to supply such Economy Energy to the extent requested by Seller.
The Buyer, having scheduled the receipt of Economy Energy, shall become disqualified to receive in part, or in entirety, such Economy Energy previously scheduled to the extent that any of the capacity included in the alternate dependable capacity at the time of such scheduling should become unavailable to Buyer; provided, however, that during an emergency on Buyer's system Buyer shall be entitled to use its reserve capacity, if required in order to carry its own load, and Buyer shall not thereby become disqualified for Economy Energy due to such use of its reserve capacity.  To the extent that Buyer becomes unable to qualify for energy previously scheduled as Economy Energy, the energy scheduled in excess of the amount of energy which can be classified as Economy Energy, as set out hereinabove, shall be paid for by Buyer in accordance with the terms and conditions of Schedule A.
Buyer shall, when so requested by Seller, make available such records as are necessary to establish that it had concurrently available, at the time of any Economy Energy transaction, alter­nate dependable capacity that could otherwise have been used to produce or furnish the energy received as Economy Energy.  Either Buyer or Seller shall, in response to request from the other, supply whatever information is necessary to a determination of the situation regarding the possibility of the exchange of Economy Energy.




B-2









Section 3 - Rates and Compensation
In case of agreement between the Companies to the Interconnection Agreement for the purchase and sale of Economy Energy, as pro­vided for herein, payment for such energy so scheduled shall be on a "dividing the savings" basis as calculated at the time of the agreement for any specific amount of Economy Energy in accordance with the following rate:
	
				
	Rate in Mills per kwh = 
	A+B
	 
	when

	 
	2
	 
	 








		
	A
	=    calculated incremental cost of supplying energy involved from sources of Buyer, in Mills per kwh




		
	B
	=    calculated incremental cost of supplying energy involved from sources of Seller, in Mills per kwh




The methods of calculating costs for A and B above shall be determined by the company making the sale.  It is intended that only incremental cost components for the particular transaction shall be taken into account.
TERMS OF PAYMENT: A bill becomes past due 10 days from the date it is transmitted by telex or other wire communication to Buyer. If not paid within 15 days from such date, a 3/4 of l% late payment charge will be added. An additional 3/4 of l% late payment charge will be added to any prior bills not paid by current bill transmittal date.
Section 4 - Term
This Service Schedule shall become effective concurrently with the Interconnection Agreement dated December 8, 1981, of which this Service Schedule is a part, and shall continue in effect for so long as said Interconnection Agreement, or any extension thereof, remains in force and effect, subject to the following pro- vision.

The minimum billing demand may be reduced by 25 mw increments upon written notice at least three (3) years advance of each increment reduction.  The minimum billing demand shall not be reduced by more than one (l) 25 mw increment in any twelve (12) month period.
BILLING ENERGY:  The EPE dispatcher will schedule the hourly demand, under an arrangement to be adopted by the Operating Committee. The kilowatt hours used for energy billing shall be the monthly sum of the scheduled hourly demands.















FUEL COST ADJUSTMENT: The energy charge will be increased or decreased per kwh of sales by an amount equal to the difference between the fuel cost per kwh of sales in the base period and the estimated cost per kwh of sales in the current month adjusted for the preceding month's estimate error. Fuel cost per kwh of net generation during the base period was 3.05 cents. The loss adjustment to the point of sale is 4.4%. The energy charge adjustment will be calculated in compliance with the formula and conditions set forth in Section 35.14 of the Regulations under the Federal Power Act (Title 18, Part I, Subchapter B of the Code of Federal Regulations).
TAX ADJUSTMENT:  Billings under this schedule may be increased by an amount equal to the sum of the taxes payable under federal, state and local sales tax acts, and of all additional taxes, fee or charges (exclusive of ad valorem, state and federal income taxes) payable by the utility and levied or assessed by any governmental authority on the public utility services rendered, or on the right of privilege of rendering the service, or on any object or event incidental to the rendition of service as the result of any new or amended laws after the effective date of this schedule.
MINIMUM BILL:  The charge for the billing demand for the month.
TERMS OF PAYMENT:  A bill becomes past due 10 days from date of mailing. If not paid within 15 days from mailing date, a 3/4 of 1% late payment charge will be added. An additional 3/4 of 1%; late payment charge will be added to any prior bills not paid by current bill mailing date.
SECTION 3 – EFFECTIVE DATE; PENALTY:
This Service Schedule shall become effective on the date of commercial operation of the Interconnection or January l, 1984, whichever is later.
In the event the commercial operation of the Interconnection is delayed beyond January l, 1984, because the transmission facilities are not available to transmit power (except for regulatory delay as provided herein),















EPE shall pay to SPS the following amounts as a penalty for EPE's failure to have said transmission facilities in commercial operation as of January l, 1984:
	
						
	COMMERCIAL OPERATION DATE
	 
	AMOUNT
	 

	January 1, 1984 to January 31, 1984

	50,000
	

	 

	June 1, 1984 and AFTER
	 
	150,000
	

	per month






EPE and SPS contemplate that EPE will have obtained all necessary regulatory approvals to commence construction of the Interconnection on or before August l, 1982. In the event that all necessary regulatory approvals have not been obtained by August 1, 1982, and, if the commercial operation of the Interconnection is delayed beyond January l, 1984, the penalty provided above shall be abated for the same number of days the necessary regulatory approvals are delayed beyond August 1, 1982; provided, however, that said abatement shall not extend beyond 6 months in total.
SECTION 4 - TERM:
This Service Schedule shall continue in effect for so long as the Interconnection Agreement, dated December 8, 1981, of which this Service Schedule is a part, or any extension thereof, remains in full force and effect, subject to the following provision.

















Nothing contained herein shall be construed as affecting in any way the right of the party furnishing service under this rate schedule to unilaterally make application to the Federal Energy Regulatory Commission for a change in rates under Section 205 of the Federal Power Act and pursuant to the Commission's Rules and Regulations promulgated thereunder.

Section 4.1.  SPS shall deliver electric power and energy to its 230 KV bus at the Eddy County DC terminal near Artesia, New Mexico. Additional delivery points may established by agreement between the Parties.
Section 4.2.  If SPS is unable to furnish Firm Power quantities as agreed at its delivery point near the Eddy County DC Terminal and is unable to deliver Firm Power quantities as agreed at an alternative point of delivery, the billing amount shall be adjusted downward. The Billing Demand for the month shall be adjusted downward by an amount equal to the ratio of the number of full hours that SPS is unable to deliver the Firm Power as agreed, divided by the total hours in the month. No Billing Demand adjustments shall be made for consecutive periods of interruption totaling less than 24 hours.


SECTION 5
Rates for Firm Power
Section 5.1.  During the term of this Service Schedule F or any extensions or renewals thereof, and subject to change as hereinafter provided, EPE shall pay SPS for Firm Power at the following monthly rates:
Customer Charge:    $320.00 per month per delivery point

	Energy Charge:
	.07 cents per KWh for all energy delivered, plus the fuel cost adjustment as provided under Section 5 .2.






F-2







Section 5.2. The above energy charges will be increased per KWh of sales equal to the estimated fuel cost per KWh of sales in the current month, adjusted for the preceding month's estimate error. The energy charge adjustment shall be calculated in compliance with the formula and conditions set forth in the Wholesale Fuel Cost Adjustment Clause contained in Attachment 1 to this Service Schedule F. Since there is no fuel cost included in base rates, the base period fuel cost per KWh of net generation is equal to zero cents.
Section 5.3.  Billings under this Service Schedule F may be increased by an amount equal to the sum of the taxes payable under federal, state and local sales tax acts, and all of the additional taxes,  fees, or charges (exclusive of ad valorem,  state and federal income taxes) payable by SPS and levied or assessed by any governmental authority on SPS services rendered,  or on the right or privilege  of rendering the service, or on any object or event incidental to the rendering of the service, as the result of any new laws after January 1, 1992.

1 – 3.754%    


		
	5.
	The current month adjustment for prior wholesale over or under collections shall be calculated as:




		
	(i)
	the first prior month's (p) actual fuel costs (aF) divided by actual sales (aS),




		
	(ii)
	minus that month's (p) estimated fuel costs (eF) divided by estimated sales (eS),




		
	(iii)
	times the wholesale loss adjustment (L),




		
	(iv)
	times actual wholesale sales (W) in that month (p) for each customer.
