If a customer terminates service under this tariff, the customer will not be eligible to receive service under this tariff until the start of the next season, as defined in the Definition of Seasons Section, after the termination. FLEX PRICE : The FP provides customers the opportunity to choose on a seasonal basis between their current standard tariff and FP. Customers, who elect to participate in the FP summer season, as defined in the Definition of Season Section, must notify the Company no later than 45 days before the start of the summer season. The Company will then provide Seasonal Customer Base Line (SCBL) information as defined in the Seasonal Customer Base Line Section. The customer will continue on the FP program for the subsequent season unless they notify the Company prior to the start of the subsequent season. If the customer elects to discontinue participation in the FP program for the next season, the customer will be placed on their prior standard tariff.

SEASONAL CUSTOMER BASE LINE (SCBL): The SCBL (specified by OG&E) represents a subscriber’s typical or expected electricity consumption level and pattern and includes the customer’s monthly maximum demand in kW and hourly energy in kWh for 12 consecutive months. For existing customers, the hourly energy of the SCBL shall be 12 consecutive months of customer-specific, historical, hourly load information adjusted for calendar day-type matching and other special circumstances that may have affected the customer’s usage pattern. The 12 monthly maximum demands of the SCBL, adjusted per the Power Factor Clause, shall be the 12 monthly billing determinants used to calculate the customer’s Standard Bill. For new customers and existing customers for which hourly load information is not available, the SCBL shall be 12 consecutive months of hourly load information which best represents a customer’s typical or expected electricity consumption level and pattern. Customer’s acceptance of the initial SCBL is a precondition for eligibility for this tariff. The SCBL will convert the hourly loads to an average weekday and weekend daily load broken in to six four hour Time-of-Use Periods, one SCBL for the weekday and one SCBL for the weekend day for all months in the season. This means that the daily weekday load pattern will be the same for all weekdays of a given month and each weekend load pattern will be the same for all weekend days of a given month. At the Company’s sole discretion, customers may be permitted to aggregate multiple accounts, under the same ownership, and the same rate, into a single SCBL. The SCBL includes a table reflecting the summation of the individual account billing demands by month. Where block rates apply, the blocks of the rate shall be multiplied by the number of accounts included in the aggregated SCBL. While a customer is taking service under this tariff, the Company may adjust the SCBL to reflect permanent substantiated changes in operating conditions. These conditions include, but are not limited to: (1) Permanent reductions in the customer’s usage due operational changes, (2) Reductions due to demand-side management investment at the customer facility, (3) Additions or upgrades to the transmission and/or distribution facilities required to serve the customer’s load, or (4) other conditions that affect the Company’s cost of providing service to the customer.

Prices will be provided by 6:00 p.m. the day before. STANDARD BILL: The Standard Bill is calculated by applying the Otherwise Applicable Rate (OAR), including all applicable riders and surcharges, to the customer’s SCBL billing determinants for the billing period. If base rates, riders, or surcharges are subsequently revised, those changes will be reflected in the customer’s Standard Bill based on their SCBL billing determinants for a given month. As required by the Company’s Terms and Conditions of Service, customers taking service under this tariff may be required to make a one-time contribution or pay a monthly facilities charge sufficient to cover the cost of any transmission and distribution facilities provided by the Company to accommodate the customer’s load. BILL DETERMINATION: A bill under this tariff is rendered after each monthly billing period and consists of a Standard Bill amount, and a charge (or credit) for incremental (or decremental) energy use based on the difference between a customer’s actual use and the customer’s SCBL in each hour multiplied by the respective Flex Price provided during the billing period. The monthly bill under this tariff is calculated using the following formula: FP BillMo. = Standard BillMo. + PriceFP Energy Charge Where: FP BillMo. = Customer’s bill for service under this option in a specific billing month Standard Bill Mo. = Customer’s bill for a specific month of use as defined by the SCBL and billed under the OAR, inclusive of all applicable riders exclusive of franchise fees and taxes PriceFP Energy Charge = ∑ [FP x (LoadHr. – SCBL)] ∑ = Sum over all time-of-use periods of the monthly billing period LoadHr. = Customer’s actual kWh use in an hour SCBL = Seasonal Customer Base Line kWh based on the SCBL time-of-use period (Subject to CO-SUBSCRIPTION of LR tariff for customers who subscribed to both FP and LR tariffs) APPROVED December 20, 2024 DIRECTOR of PUBLIC UTILITY DIVISION OKLAHOMA GAS AND ELECTRIC COMPANY 5th Revised Sheet No. 34.04 P.

CONFIDENTIALITY: Any customer taking service under this tariff shall not disclose to any person, entity, or organization any information regarding the pricing, including, but not limited to, the hourly prices offered under this tariff, without the prior written consent of the Company. Disclosure of such information, including failure to obtain prior written consent before providing such information to Consultant(s) (individuals or entities providing energy use and purchase analysis assistance to the customer) shall result in a material breach of any agreement between such customer and the Company, for which the Company shall be entitled to recover at law and at equity. Such disclosure shall at the Company’s sole option, result in suspension of service under this tariff, with a full reimbursement to the Company by the customer of the difference between the applicable standard tariff rates and the rate(s) provided pursuant to this tariff for all use billed pursuant to this tariff. FRANCHISE PAYMENT: The above stated rates do not include any amount for franchise payments levied upon the Company by a municipality. When a municipality, by a franchise or other ordinance, levies or imposes upon the Company franchise payments or fees (based on a percent of gross revenues) to be paid by the Company to the municipality, such franchise payment will be added as a percentage of charges for electric service to the bills of all customers receiving service from the Company within the corporate limits of the municipality exacting said payment. BEST BILL PROVISION: Customers will be billed on the FP prices each month during the first year of enrollment on this tariff. At the end of each season the customer’s billing will be compared to their previous tariff using the actual usage for the season and, if the amount actually paid is higher than what the customer would have paid under their previous tariff, the customer will receive a credit on their bill equal to the difference between the amount actually paid and the amount that would have been paid under their previous tariff.

APPLICABILITY: The Utility Solar Program makes available to subscribers the solar energy produced by OG&E. The program is available on a voluntary basis to all retail customers. Customers may not take service under this tariff and simultaneously take service under the provisions of any other alternative source generation or co-generation tariff. PRICING: The kWh sold through this rider are priced at $0.0982 per kWh. SUBSCRIPTION LEVEL: Customers may subscribe, in increments of 10%, up to 50% of their annual energy. During initial signup the subscriber’s annual energy will be determined in one of two ways. If during initial signup the customer has 12 consecutive months of usage history at the address where the subscription is being requested, then the annual energy will be the energy consumed during that 12 month usage history. If the customer does not have 12 consecutive months of usage history at the address where the subscription is being requested, then 12 months of annual energy will be estimated. Until OG&E expands its solar energy production beyond the initial 2.5 MW, the maximum amount any one customer may receive is 50,000 kWh per year. After the expansion of solar energy production, subscription for any one customer beyond 50,000 kWh will be at the Company’s discretion. A customer may change their subscription level only once in any 12 month period. In the event there is a significant and permanent reduction in customer usage the Company, at its sole discretion, may adjust the subscriber’s annual energy on which the subscription level is based. BILLED PURCHASE QUANTITY: The quantity of energy that will be purchased by a subscriber for each monthly billing cycle will be computed as follows: 𝑃𝑃𝑃𝑃=𝑆𝑆𝑆𝑆𝐸𝐸𝐸𝐸𝑆𝑆𝐸𝐸∗𝐸𝐸𝐸𝐸𝑆𝑆𝐸𝐸 Where PQ = Monthly Purchase Quantity in kWh SL = Annual Subscription Level in kWh EUSR = Annual Utility Solar Rated Energy Production in kWh EUSA = Actual Monthly Energy Produced by the Utility Solar Facility in kWh The EUSR and EUSA will be re-determined whenever a new solar facility is brought online or an existing solar facility is taken offline.

Should the purchased utility solar amount for a given month be larger than the customer’s metered energy consumption then the net energy will be zero. Under this tariff, only the energy (kWh) portion of a customer’s bill are affected. On a monthly basis, the customer’s energy charges will include the 1) purchased quantity of utility solar energy at the utility solar price, 2) net energy according to the applicable energy price under their rate schedule and any applicable rider schedules, and 3) the total metered energy according to any applicable riders. All other rate schedule charges are unaffected by this rider. Customer usage as determined by the annual billing prior to subscription shall be used in determination of the applicable tariff used for the customer’s billing. WAITING LIST: If at the time of subscription request a customer’s desired subscription level is greater than the available energy of the Utility Solar Facility, then the customer may elect to be placed on a waiting list. The Available Energy of the Utility Solar Facility will be computed as follows: 𝐸𝐸𝐸𝐸=𝐸𝐸𝐸𝐸𝑆𝑆𝐸𝐸− �𝑆𝑆𝑆𝑆 Where EA = Available Energy of the Utility Solar Facility EUSR = Annual Utility Solar Rated Energy Production ∑𝑆𝑆𝑆𝑆 = The sum of all subscribed Subscription Levels Customers will be moved from the waiting list into active subscriber status in the order that they are placed on the waiting list, only if Available Energy is greater than the customer’s desired Subscription Level.

PURPOSE: The Energizing Renewable Connections Program (“ERC” or “Program”) is an optional Program enabling customers to purchase renewable energy of up to 100% of their energy needs through a subscriber agreement, subject to the Program resource quantity limits. ELIGIBILITY: The ERC is available to customers who execute a corresponding agreement to subscribe for renewable resources. The ERC makes available renewable resources through voluntary participation to customers with a monthly maximum demand of 2 MW or greater. At the Company’s sole discretion, customers may be permitted to aggregate multiple accounts under the same ownership for the purposes of meeting the 2 MW requirement. If the customer does not have historical usage, the monthly maximum demand may be estimated by the Company. Other customers may subscribe with approval of the Company. All other provisions of the customers standard pricing schedules shall apply. OG&E reserves the right to limit the amount of energy provided to individual customers under this rider. Customers subscribe and receive renewable resources from a designated renewable resource at that resource’s specific price. Subscription is limited to resources offered by OG&E. OG&E is not required to contract for, acquire, or construct any resources to accommodate subscription to this tariff. SUBSCRIPTION LEVEL: The minimum subscription is 1,000 kW. Subscription is facility specific and based on the facility listed on this tariff. Customers may subscribe, in increments of 10%, up to 100% of their annual energy. During initial signup the subscriber’s annual energy will be determined in one of two ways. If during initial signup the customer has 12 consecutive months of usage history at the address where the subscription is being requested, then the annual energy will be the energy consumed during that 12-month usage history. If the customer does not have 12 consecutive months of usage history at the address where the subscription is being requested, then 12 months of annual energy will be estimated. A customer may change their subscription level only once in any 12-month period. In the event there is a significant and permanent reduction in customer usage the Company, at its sole discretion, may adjust the subscriber’s annual energy on which the subscription level is based. BILLED PURCHASE QUANTITY: The quantity of energy that will be purchased by a subscriber for each hour will be computed as follows: 𝑄𝑄𝑄𝑄𝑄𝑄𝑖𝑖 = 𝑆𝑆𝑆𝑆𝑅𝑅𝑅𝑅𝑖𝑖 × ∑𝐴𝐴𝐴𝐴𝐴𝐴𝑖𝑖𝑖𝑖 Where 𝑄𝑄𝑄𝑄𝑄𝑄𝑖𝑖 = Quantity Customer Receives in kWh SL = Subscription Level in kW 𝑄𝑄𝑅𝑅𝑖𝑖 = Rated Production in kW for Project i APPROVED December 20, 2024 DIRECTOR of PUBLIC UTILITY DIVISION OKLAHOMA GAS AND ELECTRIC COMPANY 1st Revised Sheet No. 50.41 P.

FCA EXEMPTION (only applicable for non-hourly settlement subscribers): The monthly energy use of a subscribed customer in kWh up to the customer’s QCR, whichever is less, are exempt from the Rider for Fuel Cost Adjustment ("FCA"). The monthly energy use of a subscribed customer in kWh in excess of the customer’s QCR will be subject to the then current monthly FCA. If a subscribed customer uses less energy in kWh than the customer’s QCR, an FCA Exemption credit in kWh shall be made for each kWh of the customer’s QCR in excess of energy use of the month. An FCA Exemption credit shall increase the customer’s following month’s QCR prior to every anniversary date of the customer’s subscription. On every anniversary date of the customer’s subscription, all FCA Exemption credit on the customer’s account shall be exchanged into a monetary credit at the rate of 80% of the customer’s last ERC purchase price. If a customer’s total kWh usage is less than their subscribed ERC kWh for the month, an FCA credit shall be made on the customer’s actual usage not to exceed the maximum subscription limits. If a customer’s total usage is more than their subscribed ERC kWh for the month, an FCA credit shall be applied only to the subscribed ERC kWh level. No FCA kWh credit shall be rolled forward or backward to any previous or future month’s customer billing. HOURLY SETTLEMENT: Customers who subscribe to the Program shall be billed under all of their respective applicable rate schedules in addition to the amount due from the Program participation. The amount due monthly from the Program participation shall equal to a subscriber’s total QCR for the month multiplied by the applicable subscription price. Customers who subscribe to the Program shall also be entitled to the monthly credit amount equal to the sum of the hourly QCR multiplied by the corresponding Southwest Power Pool (“SPP”) Day Ahead market hourly settlement price for all hours of the month. In lieu of hourly settlement of locational and temporal price differences, a customer may elect to pay for an OG&E established risk premium to be added to the ERC purchase rate. This rate will be updated on an annual basis. MINIMUM BILL: The minimum monthly customer bill shall be the customer charge and the amount that equals to QCR multiplied by the applicable subscription price, plus any other applicable fees and taxes. The Company shall specify a larger minimum monthly bill, calculated in accordance with the Company's Allowable Expenditure Formula in its Terms and Conditions of Service on file with and approved by the Commission, when necessary to justify the investment required to provide service.

The Company will retire the credits on behalf of the subscriber with all costs associated with the registration and retirement borne by the requesting subscriber. Alternatively, if requested, RECs associated with energy obtained through this Program can be transferred to the subscriber annually (any costs associated with this transaction shall be borne by the subscriber). WAITING LIST: For the initial ERC project offering, customers will be put on a waiting list on a first-come, first-served basis until customer interest exceeds 100 MW. At that time, the Company may pursue the procurement of a resource(s) to meet the customer need. At any time, if customer interest in the ERC exceeds the currently available limit, these customers will be placed on a waiting list and may be offered the opportunity to subscribe if subscription cancellations or forfeitures occur. Once customer interest exceeds the currently available ERC resources by 100 MW the Company, at its sole discretion, may obtain additional resources to be offered through this Program.

The SCL, specified in kW, is the amount of load the customer expects to reduce during curtailment events. Customer must specify a SCL equal to at least 10% of the customer’s maximum demand occurring during the most recent on-peak period. SCL shall be based on actual historical measured on-peak period demands. For new customers and existing customers that do not have actual historical measured on-peak period demand information, the Company will estimate an on-peak period demand that best represents a customer’s typical or expected on-peak period demand level. For a customer who subscribed to both DAP (or FP) and LR tariffs, SCL is limited to the customer’s CBL (or SCBL) of the DAP (or FP) tariff. MONTHLY SUBSCRIPTION PRICE: The monthly subscription price is determined and published by the Company based on the expected capacity values for the Contract Period.

The Performance Credit is calculated as follows for each curtailment event. PC = Σhour (kWhbase - kWhactual) * PriceCurtailment * LAF Where: PC = Performance Credit, expressed as a credit. If, for any curtailment event, the above calculation results in a negative value (charge), the PC will be $0.00. kWhbase = Baseline kWh for each hour (or portion of an hour) that the curtailment is called. kWhactual = Actual kWh for each hour (or portion of an hour) that the curtailment is called. Pricecurtailment = Curtailment Price for the event. LAF = Applicable Service Level Loss Adjustment Factor. Baseline kWh: The Baseline kWh is calculated as the average kWh in each of the same hours (or portion of hours) from the previous five work days excluding Saturday, Sunday, previous curtailment periods, and the following Company observed holidays: New Year’s Day, Martin Luther King Day, Presidents Day, Memorial Day, Independence Day, Labor Day, Veterans’ Day, Thanksgiving (Thursday and Friday), and Christmas (including Christmas Eve Day). Under certain circumstances, a customer’s specific operations may require an alternate time period for the determination of the average kWh to be used in the determination of the baseline kWh. The Company will assess these circumstances on a case by case basis. Actual kWh: The Actual kWh metered during each hour (or portion of an hour) during the curtailment event. Curtailment Price: The Curtailment Price (stated in cents per kWh) for each curtailment event will be communicated to the customer at the time the notification of the event is provided to the customer. The Curtailment Price shall reflect Southwest Power Pool conditions and Locations Marginal Day- Ahead pricing for OG&E and shall be equal to or greater than the posted Minimum Curtailment Price.

APPLICABILITY: This rider is applicable to and becomes a part of each Oklahoma retail rate schedule and is applicable to all kWh of the respective Oklahoma retail rate classes except those kWh exempted under specific tariff or special contract provisions. TERM: This rider will be in effect until modified or terminated by the Commission. DESCRIPTION: The purpose of the Storm Cost Recovery Rider (SCRR) is to recover costs associated with the operation and maintenance expenses resulting from storm damage. Recovery for actual storm costs through this rider is limited to recovery of the amounts established by OCC order. The amount to be recovered by the storm cost recovery factors shall be determined initially based on a 60 month recovery period beginning the implementation of new rates; subsequent factors shall be determined based on the remaining life of the SCRR. As an offset to storm costs, this rider credits to customers, by service level (SL), the jurisdictional portion of net revenues received from the sale of designated SO2 credits (SO2C) as described in the settlement agreement, allocated to SL using kWh by SL for the previous calendar year. The SCRR amounts to be recovered by SL are shown in the SCRR report. SCRR REPORTS AND UPDATES: Each year this rider is in effect, on or before March 1st, the Company will file with the Commission a report detailing by service level:  the total amount to be recovered, including amounts from new storms,  the amounts collected during the prior period,  any SO2 credits or other offset for over-recovery of storm costs in base rates,  the remaining balance including carrying costs established in the Company’s last rate case,  the amount to be recovered during the next period, and  the projected jurisdictional kWh sales by service level. In addition, the Company will file with the Commission the revised SCR factors for the subsequent year. The Director of the Public Utility Division will approve the revised SCR factors to become effective with the first billing cycle of the April billing month.

For customers who take service under the Company’s Net Energy Billing Option (NEBO) and Qualified Facilities (“QF”) schedules, the WES shall apply to the gross kWh of energy the Company delivers to the customers. For the DAP and FP customers, the WES rate will be calculated using the customer’s kWh energy specified in the CBL or Seasonal CBL defined in the DAP or FP tariffs. All DAP and FP kWh sales above or below the CBL will be excluded from the WES calculation. For all other rate schedules, the WES rate shall apply to the total billed kWh. CLASS REVENUE REQUIREMENT: The Revenue Requirement for the WES mechanism shall include the bond payment, associated financing fees (i.e., debt service and ongoing costs), the prior period over/under collected balance by class, and any uncollectible balances by class. The class over/under balances and class uncollectible balances are not exempt from reallocation to other classes as part of the reallocation treatment provided in the NON-STANDARD FACTOR DETERMINATION. NON-STANDARD FACTOR DETERMINATION: A non-standard factor determination is triggered when any SL class whose projected energy sales (SLs 3, 4, or 5) or blocks (SLs 1 or 2) will be 10% lower than the SL class’ projected energy sales or blocks of the same six-month period underlying the most recent Standard Factor Determination (a “Trigger Event’). If a Trigger Event occurs, then any SL class for which there is a forecasted decline in energy sales or blocks for the next period is referred to as an “affected SL class”. The non-standard factor determination of the WES rates shall be computed as follows. 1. For each affected SL class, the Company will calculate (a) a new WES rate using the higher kWh sales or blocks from the most recent Standard Factor Determination and (b) a new WES rate using the new lower forecasted sales or blocks. 2.

Where there is no terminal box, or meter or other enclosure with adequate space, the point of connection shall be considered to be the point of entrance of the service conductors into the building. “Service lateral raceway” means the raceway that encloses the service lateral from the meter base or junction box to a trench suitable for direct buried service laterals, including the 90 degree bend and conduit required to clear obstructions adjacent to the building. 202 APPLICATION FOR ELECTRIC SERVICE Each consumer, before obtaining electric service, shall make written application (unless waived by the Company) to the Company for such service at the rates applicable for the type of service to be furnished. A written application for service, when signed by the consumer and accepted and approved by the Company, constitutes a contract. An oral or electronic application for service and rendition of service pursuant thereto shall constitute a contract for service which includes all these Terms and Conditions of Service. A Service Initiation Fee of $22.50 shall be assessed to each consumer to establish a new account. The total amount of this charge shall be assessed at the time service is connected. This Service Initiation Fee shall not apply to temporary service in the name of a builder or construction company for construction power nor to an account in the name of an owner of property for service to rental units covered by a Leave-on Agreement (see Section 206). Each application for electric service shall be made in the true name of the consumer desiring the service, or using the service. The Company, at its option, may require suitable identification.

A consumer may take electric service at one location (premises) under more than one pricing schedule if separately metered. The Company, at any time upon request, will determine for any consumer the rate best adapted to existing or anticipated electric service requirements as defined by the consumer, but the consumer shall always have the final responsibility for the choice between two or more applicable rates. The Company’s standard pricing schedules state the term or period of time for which each is established. A consumer having selected a rate may not change to another rate during the applicable term. A new consumer will be given reasonable opportunity (normally not to exceed three months’ time) to determine their service requirements before definitely selecting the most favorable rate therefore. In those instances where a written agreement for electric service is required by the Company and where a new consumer selects an applicable pricing schedule or an existing consumer elects to change to another pricing schedule which is applicable to their class of service, the billing will continue under the rate in effect or applicable pricing schedule until the agreement for electric service has been properly executed by the consumer and the Company. The Company may not know of changes that occur in the consumer’s operating conditions; therefore, the Company does not assume responsibility that the consumer will be served under the most favorable rate. When the consumer selects a rate the Company will thereafter not make any refunds covering the difference between the charges under the rate in effect and those under any other rate which would be applicable to the same service. 204 EXTENSION OF CONSUMER’S WIRING SYSTEM For the purpose of obtaining a lower rate by receiving electric service through one meter, the consumer will not be permitted to extend or connect their electric wiring installation across or under a street, alley, or other public space in order to obtain service APPROVED December 20, 2024 DIRECTOR of PUBLIC UTILITY DIVISION OKLAHOMA GAS AND ELECTRIC COMPANY 6th Revised Sheet No. 107 P.

If the Company determines that the physical or electrical characteristics of the facilities served require more than one point of delivery according to good engineering and operating practice this rule may be waived. The Company may deliver by postal or private carrier a bill for service to a consumer at the address at which service is taken, or such other address designated by the consumer. The Company may deliver by electronic means a bill for service to a consumer at an electronic address designated by the consumer. Failure to receive a bill in no way exempts a consumer from liability for payment for service. 210 METER TESTING PLANS AND PROCEDURES General. The Company’s Meter Testing Plans and Procedures discussed in this Operating Practice comply with the requirements of the Oklahoma Corporation Commission rules and the American National Standards Institute (“ANSI”) Code for electricity meters, ANSI C-12. The Customer Billing file is used to determine in service meter locations, KWH usage, voltage, form and type of meter. For this reason it is important that all KWH meters be assigned an account number. Utilizing the AMI systems allows OGE to now have access to evidence of meter performance and confidence that our In-Service meters are performing properly. Selective Testing Plan All in service Standard Meters are tested as a part of the Selective Testing Plan. The term "Standard Meter" refers to single phase or poly phase, self-contained meter.

All meters which are not included in the Selective Testing Plan will be scheduled for testing utilizing a periodic interval plan. The selected periodic interval for testing a metering device depends on various conditions associated with either the metering device or the site at which the metering device is installed, such as the size of the service, KWH usage of the meter, complexity of the metering system, reliability of the type of metering device and/or manufacturer’s recommendations. The periodic testing plan groups meters together based on MWH usage. This schedule allows the Company to test its larger customers more frequently than the smaller ones with existing staff as well as ensuring field testing occurs during the life expectancies of the electronic meters. MWH Usage Test Year Greater than or equal to 1,000 2 400 – 999 4 70 – 399 8 0 – 69 12 Annual Testing Plan. Any meter requiring a test schedule more frequent than every other year or where KWH readings are not posted to the customer file is handled under the Annual Testing Plan. a. Generation Meters All KWH meters located within an OG&E Power Plant shall be tested annually. b. Interconnection Meters Meters owned by the Oklahoma Gas and Electric Company should be tested by OG&E Company members and witnessed by the other parties.

This reference is used to calibrate the department standards within plus or minus 0.2 percent. The department standards are used to check the calibration of field test units every six months. b. Meters ANSI C12.1 indicates in-service performance of all watthour meters is considered to be acceptable when the average percent registration is not less than 98.0% or more than 102.0% as determined by one of the average percent registration methods in section 5.1.4 of the standard. The performance of a Watthour meter per OGE standards is considered acceptable when the percent registration is no more than 100.5%, nor less than 99.5%, based upon the simple average of light load and heavy load and when the meter does not creep. All meters with "as found" test results that are found to be registering outside .5% of heavy load test or light load tests will be removed from service and recalibrated by the manufacturer or retired. Testing Procedures. All new poly-phase and all returned standard, poly-phase and other meters will be tested and recalibrated as necessary by Meter Shop before being installed in service. This procedure should insure that the proper maintenance has been performed on the meter and that its' accuracy meets our standards. a. Instrument Transformers All instrument transformers which are removed from service will be tested by Meter Shop before being reissued. All new PT's, high voltage CT's and 20% of the 600 volt CT's will be tested before they are placed in inventory. In service current and potential transformers should be tested as a part of the KWH meter installation test. When a meter is tested, the instrument transformers associated with the installations shall receive close visual inspection for correct connections or evidence of damage due to severe overloads for extended periods of time, physical damage or abnormal conditions. Tests of current and potential transformers shall be performed at the same time and results recorded. The current transformer shall be tested with a suitable variable-burden device to determine if the windings of the secondary circuit have developed an open circuit, short circuit, or unwanted grounds.

All new PT's, high voltage CT's and 20% of the 600-volt CT's will be tested before they are placed in inventory. c. Installation Test Transformer rated meters should be field tested within 30 days after installation. d. Complaint Test The Company will test the accuracy of any consumer’s meter within 20 days after receipt of a written request from the consumer. If the meter tested is found to be more than 2% incorrect, the Company will make no charge for such test. If the meter is found to be within the accuracy limits of plus or minus 2%, the Company will charge the consumer $130.00 to cover the costs to perform such test. The fee will be collected prior to the test and promptly refunded to the customer if the meter proves not to be accurate within the limits referenced above. It is usually quite difficult for the customer to thoroughly understand meter test procedures and the terminology used. For this reason complaint tests should be made only when desired to save time or when a logical explanation of the KWH used proves unsatisfactory to the customer. An explanation of the customer's use of energy and his problems in connection with its use generally is more effective than the actual testing of the meter. Customer relations may be improved by the judicious use of special inspections and tests on the more important meters in areas that have been subjected to a severe electrical storm, as the prompt replacement of damaged meters and equipment will materially reduce the necessity for adjustments of customer bill.

Handling of Meters Careful handling of meters issued from the Company’s inventory is necessary to not alter the "as left" calibration. Careful handling is equally important for meters being removed from service to obtain accurate "as found" tests. Test Records. a. Periodic Test Records When any meter is tested, the test report is sent to Information Services to be entered in the Meter File. Each record contains the meter number, the date of the test, the meter reading, unique number, location of the meter and results of the last two tests. This history is preserved for all meters until six months after the meter is retired. b. Selective Test Records The test data for each family of meters in Selective Test is retained in lieu of the records required in Paragraph (a) above. 211 CHANGE OF OCCUPANCY When a consumer elects to terminate service, the Company is to be notified, either by telephone, in writing, or electronically, as to the proposed effective date of such termination. The Company will read the meter on the date service is terminated, and may, at its option, disconnect the service. The meter will be read again by the Company when service is reconnected, or within thirty days after initiating service to a subsequent consumer. 212 DISCONTINUANCE OF ELECTRIC SERVICE Reconnection Charge.

INTRODUCTION Rates Authorized by the Oklahoma Corporation Commission: Public Utilities Division Stamp (Effective) (Order No.) (Case No.) January 1, 2025 745601 PUD 2023-000087 October 1, 2022 728277 PUD 202100164 July 1, 2018 679358 PUD 201700496 July 1, 2016 662059 PUD 201500273 307 ELECTRIC SERVICE AND POWER QUALITY General. Power quality refers to those characteristics in voltage, current, and frequency, which enable the consumer’s equipment to operate at all times. The presence of power disturbances indicates the occurrence of events which may disrupt, degrade, and/or destroy either the consumer’s equipment, product, data, or process. Power quality neither begins nor ends at the metering because disturbances originate from both the Company and the consumer, and propagate through the electrical system. The Company adopts the power quality terms and definitions included in the Institute of Electrical and Electronic Engineers (IEEE) Recommended Practice for Powering and Grounding Electronic Equipment -- IEEE Std. 1100-1995. Safety. All electrical wiring and apparatus connected or to be connected to the Company’s distribution system shall be installed and maintained at the consumer’s expense and in accordance with the requirements of the National Electrical Code© (NEC), as adopted by the Commission in its rules and regulations (165:35-9-1(d)3), and with all requirements prescribed by governmental authority having jurisdiction thereof. In the event of a conflict between the NEC and an applicable municipal code, the latter shall govern. The Company reserves the right to refuse to connect to any wiring or apparatus which does not meet these requirements. The Company may, without advance notice, refuse service or discontinue service to any consumer when an unsafe condition in wiring or equipment is discovered which results or is likely to result in danger to life or property. Capacity. In the event a consumer desires to add to or increase the size of their electrical equipment, they shall notify the Company sufficiently in advance so that the Company’s meter and other service equipment may be enlarged sufficiently to care for the increased load. If the consumer fails to so notify the Company, the consumer may be held responsible for any damage to the meter or other Company equipment, if caused by the increased load. Company’s Responsibility. The Company will use reasonable diligence to supply and maintain continuous electric service at the point of delivery to the consumer within the voltage limits specified by applicable rules and regulations of the Commission (see OAC 165:35, Subchapter 17). In addition, the Company will diligently strive to maintain the voltage unbalance on multiphase systems to three percent or lower at the point of delivery under no-load conditions, based on ANSI C84.1-1989.

These conditions are described in OAC 165:35, Subchapters 17-2 and 19-3. Voltage-related complaints made by a consumer will be investigated by the Company and appropriate repairs or corrections will be made to its electrical system, if necessary in order to meet the applicable standard or operating practice. Consumer’s Responsibility. The consumer’s electrical system, equipment, process, and wiring shall be protected from electrical faults and hazards in conformity to the National Electrical Code© (NEC) and other applicable local codes at the very minimum. Additional protection not required for safety, but necessary for preventing loss of equipment, product, or data due to power disturbances from abnormal conditions (e.g. lightning surges, single-phase outages to multiphase systems, etc.) shall be the responsibility of the consumer. Equipment requiring voltage characteristics more stringent than those approved in OAC 165:35-17-2 may need power conditioning equipment; if so, such power conditioners shall be installed and maintained at the consumer’s expense. It shall be understood by the consumer that wiring and grounding equipment according to the NEC is a minimum requirement necessary for safety and that it does not guarantee equipment performance. NEC Article 90-1 states that “compliance therewith and proper maintenance will result in an installation essentially free from hazard but not necessarily efficient, convenient, or adequate for good service or future expansion of electrical use.” The consumer may need to apply wiring and grounding practices which exceed those required by the NEC, without violating the NEC, in order for some equipment to operate satisfactorily. The customer must allow employees of OG&E and its authorized agents to enter the premises at all reasonable times, or at any hour if for the sole purpose of restoring service, to: inspect, erect, install, maintain, upgrade, convert, remove, or replace OG&E’s wiring apparatus and other facilities; read the meter; and perform other activities necessary to provide electric service, including tree trimming and tree removal where such trees in the opinion of OG&E constitute a hazard to OG&E personnel or facilities, or the provision of continuous electric service.

OG&E representatives are forbidden to demand or accept any compensation for services rendered in line with their duty unless an OG&E printed receipt is given. The customer is requested to report immediately to OG&E any discourtesy or any contact that seems suspicious. Harmonics and Interference. A large percentage of the loads connected to the electrical system are electronic and produce harmonics, which are whole multiples of the fundamental power frequency. Both the Company and the consumer shall design their power distribution systems to meet or exceed the recommended harmonic levels, as measured at the point of delivery, in accordance with Std. 519-1995. Whether the recommended harmonic levels have been exceeded or not, if one consumer operates in such a way so as to cause objectionable interference to the Company, its consumers, or another electric or communications company and its consumers, the Company may take actions as outlined in OAC 165:35-25-3(e). The Company maintains the right to require the offending consumer to bear the cost of any corrective action needed to keep the electric system operating within approved standards and practices as stated elsewhere in its terms and conditions. The Company as well as communications companies will meet or exceed applicable standards associated with noise and other forms of interference. All parties involved in the generation or transmission of objectionable noise or interference will work together toward a cost-effective and reasonable solution to the satisfaction of the consumer who is adversely impacted. Motors - Allowable Starting Currents. The following motors may be started across-the-line if the starting current (which is the locked rotor current of the motor at nameplate voltage) does not exceed the limits given below: Nominal Name Plate Voltage Phase Maximum Locked Rotor Current* 120 - volts Single 50 amperes 208 or 240 - volts Single 200 amperes 208, 240 or 480 - volts Three 200 amperes APPROVED December 20, 2024 DIRECTOR of PUBLIC UTILITY DIVISION OKLAHOMA GAS AND ELECTRIC COMPANY 6th Revised Sheet No. 142 P.

Larger across-the-line starting currents than those stated above may be permitted where the Company’s facilities are adequate and the frequency of starts are such that other consumers’ service will not be adversely affected. Upon request of the consumer, the Company will make individual studies to determine the maximum allowable starting current for each specific installation and if necessary recommend a motor starting device. When part-winding, wye-delta, auto transformer or resistor type motor starting devices are required, closed transition transfer from the starting to running condition must be used unless an open transition type starter is specifically approved. In the case of thermostatically controlled air conditioning or heat pumping equipment, a time delay device to prevent simultaneous starting of the compressor motor and associated fan motors is an acceptable method for reducing the locked rotor starting currents to acceptable values. Abnormal Conditions and Damages. The Company will not be liable for any damages or losses incurred by a consumer during any service interruptions or other power disturbances that are due to an abnormal or emergency operating condition, unless the evidence shows that the event was caused by the sole negligence of the Company. It is the consumer’s responsibility to provide adequate protection from any potential power disturbance which may occur on the entire electrical distribution system. In order to make repairs to or changes in the Company’s facilities for supplying electric service, the Company reserves the right, without incurring any liability therefore, to suspend service without notice to a consumer for such periods as may be reasonably necessary.

The Extension Policy shall be considered in conjunction with the provisions of the Company’s various pricing schedules and other provisions of these Terms and Conditions of Service. This Extension Policy is articulated in compliance with the Oklahoma Corporation Commission’s Electric Utilities Rules, Oklahoma Administrative Code (OAC or Code) 165: 35-25-2. A basic philosophy of the Company is to provide the best possible service and point of delivery of service to the consumer at the most reasonable investment. All applicable alternatives shall be given consideration when applying the extension policy. Extension of the Company’s distribution system to supply permanent service for a residential service will be made in general accordance with OAC 165:35-25-2(a). All other new electric extensions, electric system modifications requested by the consumer, or required electric system modifications caused by the consumer will be considered in accordance with Section 408, Allowable Expenditure Formula. This supersedes all previously issued directives concerning the extension policy. Non-payment of any charge, prepayment, or rental charge shall be considered a violation of these Terms and Conditions of Service. 402 RIGHT OF WAY The consumer shall, upon request, furnish a written easement for the location of the Company’s service facilities upon the consumer’s premises. In the event the consumer is not the owner of the premises occupied, such consumer shall be required to obtain from the property owner or owners the necessary easement for the installation, maintenance and operation of the Company’s service facilities on or under said premises.

In addition, at the option of the Company, a portion of or all of the payment may be waived or refunded based on the revenue from service rendered. 411 PERFORMANCE GUARANTY AGREEMENT The Company may require the Consumer to enter into a Performance Guaranty Agreement as a result of Consumer’s request for new electric service or modifications to existing electric service. The purpose of this performance guaranty agreement is to ensure the Company recovers its investment for infrastructure additions and/or improvements when the consumers projected load does not materialize and it is unlikely that the facilities would be required by another consumer within five years of the system expansion. The Performance Guaranty Agreement does not apply in lieu of CIAC. Nothing in this Agreement shall be construed as prohibiting Company from collecting from Applicant a CIAC for electric service, where otherwise applicable. 412 PERFORMANCE GUARANTY AMOUNT APPROVED December 20, 2024 DIRECTOR of PUBLIC UTILITY DIVISION OKLAHOMA GAS AND ELECTRIC COMPANY 5th Revised Sheet No. 150 P.
