--------------------------------------------

Corrected point of interconnection

6.1

Delivery Point

The point of delivery for power and energy made available under this Contract shall be the point of interconnection between the Distributor’s 13.09 kV load side primary bushings of each of Distributor’s primary metering current transformers and the Company’s 13.09 kV primary overhead conductors.

6.2

Delivery Voltage and Frequency

The power made available at the Delivery Point specified in this Contract shall be in the form of three-phase alternating current, 13.09kV nominal, and at a frequency of approximately 60 hertz. To avoid unusual fluctuations or disturbances on Distributor’s system, Company shall meet the minimum requirements specified by Distributor for voltage flicker, harmonics (such as harmonic current distortion), and other electrical characteristics consistent with generally accepted electric utility industry practices (such as ANSI C84.1 – 2020, American National Standard for Electric Power Systems and Equipment – Voltage Ratings (60 Hertz) and IEEE 519-2022 Standard for Harmonic Control in Electric Power Systems). Company shall provide, at its expense, suitable apparatus that will reasonably meet such Distributor requirements.

Maintenance by Distributor at the Delivery Point of the above-stated frequency and voltage within the above-stated limits shall constitute availability of power for purposes of this Contract.

6.3

Phase Balancing

Company shall endeavor to take and use power and energy in such manner that the current will be reasonably balanced on all three phases. In the event that any check indicates that the current on the most heavily loaded phase exceeds the current on either of the other phases by more than twenty percent (20%), Company shall make at its expense, upon request by the Distributor, the changes necessary to correct the unbalanced condition. If an unbalanced condition is not corrected within 60 days, or such other period as may be agreed upon, Distributor may elect to meter the load on individual phases and compute the total demand as being equal to three (3) times the maximum kW load on any phase. For all purposes under this Contract, the load on any phase shall be the load measured by a wattmeter connected with its current coil in that phase wire and its potential coil connected between that phase wire and the neutral voltage point.

6.4

Protective Equipment

Distributor shall not be obligated to provide equipment for the protection of Company’s lines, facilities, or equipment, but Distributor may provide such protective equipment as it deems necessary for the protection of its own property and operations. The electrical equipment installed by Company shall, in Distributor's sole judgment, be capable of satisfactory coordination with any protective equipment installed by Distributor. Company shall exercise all reasonable precautions and install all equipment necessary to limit its total demand to the amount to which it is entitled under this Contract.

6.5

Facilities

Company grants to Distributor for its use and without cost, such rights in, on, over, and across Company’s property as may be necessary or desirable to permit the maintenance, operation, repair, and replacement of Distributor’s electrical facilities required to serve Company. Such rights shall be subject to Company’s safety and security rules and regulations, which are provided to Distributor. Notwithstanding anything in this Contract which might be construed to the contrary, any of the electric substation facilities used in supplying power to Company under this Contract may be used in serving other loads in any manner which Distributor may deem necessary or desirable; provided, however, that in exercising such right of ingress and egress the Distributor will use regularly

established roads or passageways and provide the Company the names of individuals entering the Company's property.

6.6

Metering

6.6.1

Determination of Power and Energy. Distributor shall be responsible for the installation and maintenance of the meters and associated equipment which in Distributor's judgment are needed to determine the amounts of power and energy used by Company.

6.6.2

Metering Outputs. Should Company desire access to wetted contact “kyz” pulse metering outputs from the Distributor’s metering installation for such purposes as monitoring and load control; TVA and Distributor are willing to make such access available to Company. Accordingly, Distributor may, if requested by Company in writing, provide and install at Company’s expense such additional facilities as are necessary for Company to access to “kyz” pulse metering outputs at the Distributor’s metering installation.

6.6.2.1

Noninterference with Metering. In exercising access to metering outputs Company shall not interfere with any operation, use of, or access to the metering installation by Distributor or TVA. In this regard Company agrees to immediately modify its facilities and operations in any manner as may be requested by Distributor or TVA to avoid any such interference.

6.6.2.2

No Warranty of Outputs. Neither Distributor nor TVA makes any statement, representation, claim, guarantee, assurance, or warranty of any kind whatsoever, including, but not limited to, representations or warranties, express or implied, (a) as to the accuracy or completeness of the metering outputs or as to such outputs' merchantability or fitness for any purposes for which Company uses or will use them or (b) as to quantity, kind, character, quality, capacity, design, performance, compliance with specifications, condition, size, description of any property, merchantability, or fitness for any use or purpose of any facilities through which the metering outputs are supplied. Company hereby waives, and releases Distributor, the United States of America, TVA, and their agents and employees from, any and all claims, demands, or causes of action, including, without limitation, those for consequential damages, arising out of or in any way connected with Company's use of the metering outputs.

6.7

Conditions of Delivery

Company shall not use electric service furnished by Distributor in such a manner as to cause excessive voltage fluctuations or distortions on Distributor’s electric system. Example sources of excessive voltage fluctuations and distortions shall include but are not limited to motor loads and processes which cause flicker, harmonic producing loads, and capacitor applications interacting with the Distributor’s system. Company shall not install and operate equipment that creates harmonic current or transients that cause excessive distortion to Distributor’s sinusoidal voltage waves. Determination of Company generated voltage fluctuations and waveform distortion will be made solely at Distributor’s discretion, by Distributor, based on standards and policies adopted by Distributor. Distributor may, as a condition of providing service, or as a condition of continuance of service, require Company at Company’s own expense to provide suitable apparatus that will limit such fluctuations and distortions to levels deemed appropriate by Distributor. In the event of Company’s inability or refusal to remedy or rectify Distributor’s concerns, Distributor may discontinue service.

LARGE DATA SERVICE RATES-SCHEDULE DC

(October 2026)

Availability

These rates and requirements shall apply to the electric power requirements where (a) a customer’s currently effective onpeak or offpeak contract demand, whichever is higher, is greater than 5,000 kW, and (b) the major use of electricity is for activities conducted at the delivery point serving that customer which are (1) classified with 2022 North American Industry Classification System (NAICS) subsector codes 518 or 519 (but excluding 519210), (2) classified with 2022 NAICS codes 522320 or 541214, or (3) used, in TVA’s sole judgment, for the operation of computational equipment; provided that the other conditions of this section are met.

Service under this rate schedule is subject to any certification requirements as TVA may require. Any customer taking service under this rate schedule is subject to the Capacity Commitment

Charge Rider (“CCC Rider”) for any new or expanded load. Prior to the effective date of any contract for

new or expanded load, any charge calculated under the CCC Rider must be paid by the customer to TVA in accordance with payment instructions and terms provided by TVA. Additionally, prior to entering into any contract for power for new or expanded load, Distributor must notify and consult with TVA. Distributor and customer will contract with TVA, as deemed necessary by TVA, to provide for any TVA-required conditions applicable to delivery of power and energy from TVA to Distributor and from Distributor to customer. Such conditions may include, but are not limited to, power interruption provisions and operating restrictions and guidelines, or installation of special power regulation equipment.

Unless otherwise provided for in a written agreement between TVA and the distributor providing service under this rate schedule, for customers served under this rate schedule, the customer’s “meter-reading time” shall be 0000 hours CST or CDT, whichever is currently effective, on the first day of the calendar month following the month for which a bill under this rate schedule is being calculated. Further, in accordance with TVA-furnished or TVA-approved guidelines or specifications, TVA shall have unrestricted remote access to the metering data at all times, as well as unrestricted physical access to the metering facilities for the purpose of confirming remotely-accessed data during such periods as are specified by TVA.

For a customer requesting that its onpeak contract demand be different from its offpeak contract demand, this rate schedule shall be available only for (1) a new contract, (2) a replacement or renewal contract following expiration of the existing contract, or (3) a replacement or renewal contract or an amended existing contract in which the customer is increasing its demand requirements above the existing contract demand level, but under this item (3) neither the new onpeak nor the new offpeak contract demand shall be lower than the customer's existing contract demand.

The DCB rates below shall apply to customers with an onpeak or offpeak contract demand, whichever is higher, greater than 5,000 kW, but not more than 15,000 kW; DCC rates below shall apply to customers with an onpeak or offpeak contract demand, whichever is higher, greater than 15,000 kW, but not more than 25,000 kW; DCD rates below shall apply to customers with an onpeak or offpeak contract demand, whichever is higher, greater than 25,000 kW.

Character of Service

Alternating current, single- or three-phase, 60 hertz. Power shall be delivered at a transmission voltage of 161 kV or, if such transmission voltage is not available, at the highest voltage available in the vicinity, unless at the customer's request a lower standard voltage is agreed upon.

DC Oct 2026

Page 2 of 13

Base Charges

The base charges for DCB, DCC, and DCD are set forth under the Base Charges Attachment to the rate schedule. Any references to the Base Charges section for this Schedule DC or the DCB, DCC, and DCD rates will be deemed to include the Base Charges Attachment.

Adjustment

The base demand and energy charges shall be increased or decreased in accordance with the current Adjustment Addendum published by TVA.

Facilities Rental Charge

There shall be no facilities rental charge under this rate schedule for delivery at bulk transmission voltage levels of 161 kV or higher. For delivery at less than 161 kV, there shall be added to the customer's bill a facilities rental charge. This charge shall be 36¢ per kW per month except for delivery at voltages below 46 kV, in which case the charge shall be 93¢ per kW per month for the first 10,000 kW and 73¢ per kW per month for the excess over 10,000 kW. Such charge shall be applied to the higher of

(1) the highest billing demand established during the latest 12-consecutive-month period or (2) the customer's currently effective onpeak or offpeak contract demand, whichever is higher, and shall be in addition to all other charges under this rate schedule, including minimum bill charges.

Reactive Demand Charges

If the reactive demand (in kVAR) is lagging during the 30-consecutive-minute period beginning or ending on a clock hour of the month in which the customer's highest metered demand occurs, there shall be added to the customer's bill a reactive charge of $1.46 per kVAR of the amount, if any, by which the reactive demand exceeds 33 percent of such metered demand. If the reactive demand (in kVAR) is leading during the 30-consecutive-minute period beginning or ending on a clock hour of the month in which the customer's lowest metered demand (excluding any metered demands which are less than 25 percent of the highest metered demand) occurs, there shall be added to the customer's bill a reactive charge of $1.14 per kVAR of the amount of reactive demand. Such charges shall be in addition to all other charges under this rate schedule, including minimum bill charges.

Determination of Seasonal Periods

Summer Period shall mean the June, July, August, and September billing months. Winter Period shall mean the December, January, February, and March billing months. Transition Period shall mean the April, May, October, and November billing months.

Determination of Onpeak and Offpeak Hours

Except for Saturdays, Sundays, November 1, and the weekdays that are observed as Federal holidays for New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day, Onpeak hours for each day shall for purposes of this rate schedule be from 1 p.m. to 7

p.m. during the months of April, May, June, July, August, September and October and from 4 a.m. to 10

a.m. during the months of January, February, March, November, and December. For all other hours of each day and all hours of such excepted days shall be offpeak hours. Such times shall be Central Standard Time or Central Daylight Time, whichever is then in effect. Said onpeak and offpeak hours are subject to change by TVA. In the event TVA determines that such changed onpeak and offpeak hours are appropriate, it shall so notify Distributor at least 12 months prior to the effective date of such changed hours.

Determination of Onpeak and Offpeak Demands, Maximum Metered Demand, and Energy Amounts

The onpeak and offpeak kWh for any month shall be the energy amounts taken during the respective hours of the month designated under this rate schedule as onpeak and offpeak hours; provided, however, that notwithstanding the metered energy amount, the offpeak energy for any month shall in no case be less than the product of (1) the offpeak billing demand as calculated in the last paragraph below and (2) 110 hours (reflecting a 15 percent load factor applied to the average number of hours in a month).

Distributor shall meter the onpeak and offpeak demands in kW of all customers taking service under this rate schedule. The onpeak metered demand and offpeak metered demand for any month shall be determined separately for the respective hours of the month designated under this rate schedule as onpeak and offpeak hours and, in each case, shall be the highest average during any 30-consecutive-minute period beginning or ending on a clock hour.

Except as provided below, (1) the onpeak billing demand shall be the highest onpeak metered demand in the month, (2) the offpeak billing demand shall be the highest offpeak metered demand in the month, and (3) the maximum billing demand shall be the higher of the onpeak billing demand or offpeak billing demand in the month.

The onpeak billing demand shall in no case be less than the sum of (1) 30 percent of the first 5,000 kW, (2) 40 percent of the next 20,000 kW, (3) 50 percent of the next 25,000 kW, (4) 60 percent of

the next 50,000 kW, (5) 70 percent of the next 100,000 kW, (6) 80 percent of the next 150,000 kW, and

(7) 85 percent of all kW in excess of 350,000 kW of the higher of the currently effective onpeak contract demand or the highest onpeak billing demand established during the preceding 12 months.

The offpeak billing demand shall in no case be less than the sum of (1) 30 percent of the first 5,000 kW, (2) 40 percent of the next 20,000 kW, (3) 50 percent of the next 25,000 kW, (4) 60 percent of

the next 50,000 kW, (5) 70 percent of the next 100,000 kW, (6) 80 percent of the next 150,000 kW, and

(7) 85 percent of all kW in excess of 350,000 kW of the higher of the currently effective offpeak contract demand or the highest offpeak billing demand established during the preceding 12 months.

Minimum Bill

The monthly bill under this rate schedule, excluding any facilities rental charges and any reactive charges, shall not be less than the sum of (1) the base customer charge and administrative charge, (2) the portion of the base demand charge, as adjusted, applicable to onpeak billing demand applied to the customer's onpeak billing demand, (3) the portion of the base demand charge, as adjusted, applicable to maximum billing demand applied to the to the customer's maximum billing demand, (4) the base onpeak energy charge, as adjusted, applied to the customer's onpeak energy takings, and (5) the base offpeak energy charge, as adjusted, applied to the higher of customer's actual offpeak energy takings or the minimum offpeak energy takings amount provided for in the first paragraph of the section of this rate schedule entitled “Determination of Onpeak and Offpeak Demands, Maximum Metered Demand, and Energy Amounts.” Notwithstanding the foregoing, amounts calculated under any fuel cost adjustment

DC Oct 2026

Page 4 of 13

that is included in the Adjustment Addendum shall not be applied to any billed offpeak energy that exceeds the metered offpeak energy.

Excess demand charges are excluded from this calculation.

Distributor may require minimum bills higher than those stated above, including, without limitation, charges to cover any additional metering and related costs.

Contract Requirement

Distributor shall require contracts for all service provided under this rate schedule. The contract for customers served under DCB and DCC rates shall be for an initial term of at least 5 years and any renewals or extensions of the initial contract shall be for a term of at least 1 year; after 10 years of service, any such contract for the renewal or extension of service may provide for termination upon not less than 4 months’ notice. The contract for customers served under DCD rates shall be for an initial term of at least 5 years and any renewals or extensions of the initial contract shall be for a term of at least 5 years; after 10 years of service, any such contract for the renewal or extension of service may provide for termination upon not less than 16 months’ notice. The customer shall contract for its maximum requirements, which shall not exceed the amount of power capable of being used by customer, and Distributor shall not be obligated to supply power in greater amount at any time than the customer's currently effective onpeak or offpeak contract demand. If the customer uses any power other than that supplied by Distributor under this rate schedule, the contract may include other special provisions. The rate schedule in any power contract shall be subject to adjustment, modification, change, or replacement from time to time as provided under the power contract between Distributor and TVA.

Prior to entering into any contract for power for new or expanded load, Distributor must notify and consult with TVA. Distributor and Company will contract with TVA, as deemed necessary by TVA, to provide for any TVA-required conditions applicable to delivery of power and energy from TVA to Distributor and from Distributor to the customer.

The contract demand amounts and applicable rates specified in the contract may be adjusted by TVA as provided under this paragraph. For customers served under DCB, DCC, or DCD rates, beginning October 1, 2027, and occurring each October 1 thereafter, TVA will calculate the customer’s highest onpeak and offpeak billing demand, established in the preceding 36 months. In the event that the customer's onpeak and/or offpeak billing demand is below 75% of the onpeak or offpeak contract demand, which is higher, TVA will provide at least 60 days’ written notice of an adjustment to the onpeak and/or offpeak contract demands. Said adjustment to the onpeak and/or offpeak contract demands would be established by dividing the customer’s highest onpeak or offpeak billing demand from the preceding 36 months by 0.75. Distributor will promptly notify the customer, in writing, of the adjusted contract demand amounts and the TVA-specified effective date. In the event the adjustment of the contract demand warrants the customer being served under a different rate schedule, the applicable rate schedule will be attached to said notice. Within 30 days of the date of the notice from TVA, Distributor may submit to TVA a request for a one-year exemption due to force majeure or other events outside of the customer’s control that are impacting the onpeak or offpeak billing demand. TVA will approve such request so long as (1) the customer has previously met or exceeded 75% of its onpeak or offpeak contract demand, whichever is higher, and (2) customer demonstrates, to TVA’s satisfaction, customer’s plan for meeting or exceeding 75% of its contract demand.

The requirement set forth in preceding paragraph shall not apply to customers that have been supplied with service through a single-point of delivery for less than ten years. The requirement set forth in the preceding paragraph also shall not apply to federal customers whose primary use of power supports activities essential to national defense. For purposes of this provision, a customer’s use of power shall be considered in support of national defense when the predominant use of electricity directly

DC Oct 2026

enables activities, operations, or facilities determined by TVA to be directly tied to national defense needs.

Payment

Bills under this rate schedule will be rendered monthly. Any amount of the bill that is unpaid after the due date specified on bill may be subject to additional charges under Distributor's standard policy.

Failure by the customer to pay to TVA any amount due under the CCC Rider will be deemed a failure by the customer to have paid its power bill and all remedies available for non-payment of the power bill will be applicable for any amount due.

Single-Point Delivery

The charges under this rate schedule are based upon the supply of service through a single delivery and metering point, and at a single voltage. If service is supplied to the same customer through more than one point of delivery or at different voltages, the supply of service at each delivery and metering point and at each different voltage shall be separately metered and billed.

Service is subject to Rules and Regulations of Distributor.

Base Charges Attachment

Any customer taking service under this rate schedule is subject to the Capacity Commitment Charge Rider for any new or expanded load. Prior to the effective date of any contract for new or expanded load, any charge calculated under the Capacity Commitment Charge Rider must be paid by the customer to TVA in accordance with payment instructions provided by TVA.

As used in this Base Charges Attachment, amounts designated in the format “Rate-FY27”, “Rate-FY28”, and “Rate-FY29+” shall be applied in the following manner: Rate-FY27 will be applicable for the period of October 2026 through September 2027; Rate-FY28 will be applicable for the period of October 2027 through September 2028; and Rate-FY29+ will be applicable for the period of October 2028 onward. All rate amounts, regardless of whether they are in effect at the time, continue to be subject to the Adjustments section of this rate schedule.

Capacity Commitment Charge Rider

This Capacity Commitment Charge Rider (“Rider”) will be in addition to all charges applicable under the “Large Data Service Rates -- Schedule DC” to which this Rider is attached. For applicability of this Rider, a customer (served by either the Tennessee Valley Authority (“TVA”) or a Distributor under Schedule DC) is required to pay the Capacity Commitment Charge for new or expanded load if the customer meets one or more of the following criteria:

•

is a new customer that will be served by TVA or by a Distributor at a new end-use delivery point and the power consumed by the customer meets the eligibility requirements in the “Availability” section of Schedule DC;

•

is a new customer that has acquired an existing end-use delivery point served by TVA or by a Distributor and the power consumed by the new customer meets the eligibility requirements in the “Availability” section of Schedule DC;

•

is an existing customer that repurposes its existing end-use delivery point that was most recently utilized to consume power that met the eligibility requirements for a rate schedule other than Schedule DC and the power consumed by the customer at the repurposed delivery point meets the eligibility requirements in the “Availability” section of Schedule DC; or

•

is an existing customer requesting an increase in the specified contract demand for its existing end-use delivery point and the power consumed by the customer meets the eligibility requirements in the “Availability” section of Schedule DC.

For new load requests, the Capacity Commitment Charge will only apply above the first 5 MW of contract demand. Existing loads (as defined below) may request a one-time, location-specific, 5 MW or less waiver, of the Capacity Commitment Charge for load expansions.

For customers that meet the eligibility requirements in the “Availability” section of Schedule DC, “Existing” load is not subject to the Capacity Commitment Charge. A customer’s load is considered “Existing” if:

•

a customer has received TVA Board approval for power supply arrangements for a new load or expansion load prior to June 1, 2026; or

•

a customer has an effective power contract for the new or expanded load with either TVA or a Distributor of TVA power prior to October 1, 2026, provided that any effective contract between a Distributor and end-use customer will only be considered “Existing” where proper coordination with TVA has occurred in accordance with the wholesale power contract.

In the event (1) Distributor and a customer enter into a new power contract, or amend an existing power contract to increase power availability, and (2) the power consumed or to be consumed by the customer meets the eligibility requirements in the “Availability” section of Schedule DC, and (3) Distributor and/or Company have not properly coordinated with TVA as required under the power contract between TVA and Distributor and other TVA-established coordination policies and procedures, then the customer’s load will be considered new or expanded load and the provisions of this Rider will apply.

The Capacity Commitment Charge is a TVA Board-approved charge calculated on a per MW basis and represents the cost of building the additional generation assets needed to serve the next MW of capacity (“Incremental Capacity Cost”) that would not be recovered through the rates provided in Large Data Service Rates -- Schedule DC. Capacity Commitment Charge payments are non-refundable.

At least once each fiscal year, the TVA Board will establish a specified MW amount of capacity available for that fiscal year (“Cohort Threshold”) and approve a Capacity Commitment Charge that will apply to the Cohort Threshold until either (a) the Cohort Threshold is met or (b) the fiscal year passes and a new Capacity Commitment Charge is established and approved by the TVA Board for the next Cohort.

Available capacity (MW) in each Cohort Threshold will be applied to customers on a first-come, first-serve

DC Oct 2026

Page 13 of 13

basis. All customers who have secured capacity (MW) available under the Cohort Threshold will make up the “Cohort.” Each Cohort member will be subject to the same Capacity Commitment Charge and interruption requirements established by TVA (currently designated as power interruption provisions “PIP") until the date TVA no longer requires such interruption provisions (“Firm Generation Date”).

The customer will secure a spot in the then-current Cohort and the Capacity Commitment Charge for the Firm Generation Date will become fixed upon complete execution of the TVA-required contractual arrangements (under which there are Capacity Commitment Charge payment obligations) between TVA and the customer (and Distributor, if applicable). In the event customer fails to take power within five (5) years of the Firm Generation Date, the greater of 1) the Capacity Commitment Charge based on the Firm Generation Date, or 2) the then-current Capacity Commitment Charge, will apply.

For fiscal year 2027, the first Cohort Threshold is 2,000 MW (“Cohort 1”), and the Capacity Commitment Charge is $1.521 million/MW. Specific PIP requirements required by TVA will be set forth in any TVA-required contractual arrangement necessary for service to the customer. Future Cohort Thresholds and the applicable Capacity Commitment Charge will be determined by the TVA Board and applied as set out above. Future Cohort members will be subject to any interruption requirements established by TVA.

For initial implementation, the Capacity Commitment Charge will not apply to new or expanded load requests 100 MW or less that are deemed to be “inflight” in accordance with criteria established by TVA. Inflight load requests will be subject to the same PIP requirements established by TVA for Cohort 1.

In the case of the first billing of new accounts (temporary service and other seasonal customers excepted) and final billings of all accounts (temporary service excepted) where the period covered by the billing involves fractions of a month, the demand charges will be adjusted to a basis proportionate with the period of time during which service is extended.

25.

Information to Consumer: Columbus Light and Water will reasonably inform customers about rates and service practice policies by making such information available upon application for service and at any other time upon request. Columbus Light and Water, on request and subject to additional charges, will provide a statement of the monthly consumption for the prior months if it is reasonably ascertainable. Columbus Light and Water, as it determines appropriate, will utilize channels such as

mail, newsletter, newspaper, radio, and television to inform customers about rates (both locally-initiated and initiated by lVA) and service policies. Furthermore, Columbus Light and Water will provide information regarding rates, service practice policies, dispute resolution processes, and guidelines to customers via the website and information including brochures and print media will also be available in our offices.

26.

Termination of Service: Service may not be terminated for nonpayment of a bill except after affording the affected customer due process. Reasonable prior written notice (including notice of available rights and remedies) shall be given before termination of nonpayment. Customer can conta<;t a Customer Service Representative at (662)328-7192 to review the Due Process Procedures for Disputed Bills which are printed on the back of these Rules and Regulations.

Potential remedies are prefaced with an initial investigation and, if adverse decisions are rendered, follow up escalation steps up to and including initiation of the lVA Complaint Resolution Process.
