Code § 4905.13 : : : : : : : Case No. 22-0900-EL-SSO Case No. 22-0901-EL-ATA Case No. 22-0902-EL-AAM _________________________________________ STIPULATION AND RECOMMENDATION _________________________________________ Pursuant to Ohio Adm.Code 4901-1-30, any two or more parties may enter into a written stipulation concerning a proposed resolution of some or all of the issues in a proceeding of the Public Utilities Commission of Ohio ("Commission"). This Stipulation and Recommendation ("Stipulation") sets forth the understanding and agreement of the parties that have signed below ("Signatory Parties"), who recommend that the Commission approve and adopt this Stipulation without modification to resolve all issues in the above-captioned proceeding. This Stipulation reflects a just and reasonable resolution of the issues in this proceeding. It is the product of serious, arms-length bargaining among the Signatory Parties. All parties were invited to discuss and negotiate this Stipulation, and it was openly negotiated among those parties that chose to participate; no party was excluded from these negotiations. This Stipulation is supported by adequate data and information, and as a package, benefits customers

2 and the public interest. This Stipulation violates no regulatory principle or practice; indeed, it complies with and promotes the policies and requirements of Title 49 of the Ohio Revised Code. This Stipulation accommodates the diverse interests represented by the Signatory Parties and is entitled to careful consideration by the Commission. WHEREAS, The Dayton Power and Light Company d/b/a AES Ohio ("AES Ohio" or the "Company") is a public utility engaged in the business of supplying electric distribution service to more than 500,000 customers in West Central Ohio; WHEREAS, in order to comply with R.C. 4928.143, AES Ohio filed an Application and Supporting Testimony, Schedules, and Workpapers in this proceeding in which it sought approval of its fourth Electric Security Plan ("ESP 4"); WHEREAS, the Signatory Parties engaged in extensive discovery in this proceeding, with AES Ohio responding to at least 1043 interrogatories, 163 requests for production of documents, and 36 requests for admission (all including subparts), including: City of Dayton: 3 requests for production of documents; Constellation: 59 interrogatories, 13 requests for production of documents, and 5 requests for admission; IGS: 60 interrogatories and 3 requests for production of documents; Kroger: 4 requests for production of documents; OCC: 633 interrogatories and 84 requests for production of documents; OEC: 21 interrogatories and 3 requests for production of documents; OEG: 8 interrogatories;

3 OELC: 3 requests for production of documents; OMAEG: 19 interrogatories and 10 requests for production of documents; One Energy: 12 interrogatories and 6 requests for production of documents; RESA: 224 interrogatories, 29 requests for production of documents; and 31 requests for admission; and Walmart: 7 interrogatories and 5 requests for production of documents ; WHEREAS, the terms of this Stipulation are reasonable to ensure that AES Ohio can maintain its financial integrity and upgrade its distribution infrastructure so that customers can continue to receive safe and reliable service; and WHEREAS, the terms and conditions of this Stipulation satisfy the policies of the State of Ohio as set forth in R.C. 4928.02. NOW, THEREFORE, in order to resolve all of the issues raised in this proceeding, the Signatory Parties stipulate, agree, and recommend that the Commission issue an Opinion and Order in this proceeding accepting and adopting this Stipulation without material modification. I. Application Approval A. The Signatory Parties recommend that the Company’s Application be approved unless otherwise modified below, in order to fully resolve all of the issues raised in these proceedings, except as set forth in Section III.A.

4 II. ESP Term A. The term of ESP 4 shall be three years. III. Supply and Pricing of Electric Generation Service A. AES Ohio shall maintain 100% competitive bidding for its Standard Service Offer (“SSO”) load and will conduct two auctions annually through the term of ESP 4. AES Ohio shall follow the competitive bid process described in the testimony of AES Ohio Witness Lee, or as modified by any process proposed by any Signatory Party and approved by the Commission as set forth below. Any Signatory Party may present proposed modifications to AES Ohio’s competitive bid process and Master Service Agreement for its SSO load at the evidentiary hearing in this proceeding through direct testimony for the Commission’s consideration. Any Signatory Party may support or oppose such proposed modifications. For avoidance of doubt, any Commission decision on any Signatory Party’s proposed modifications that changes AES Ohio’s competitive bid process or Master Service Agreement for its SSO load1 shall not be considered a modification of this Stipulation.2 1 For further avoidance of doubt, any modification of AES Ohio’s competitive bid process or Master Service Agreement pursuant to the Commission’s investigation commenced on January 3, 2023 in Case Nos. 16-776-EL- UNC, 17-957-EL-UNC, 17-2391-EL-UNC, and 18-6000-EL-UNC shall not be considered a modification of this Stipulation. 2 RESA and IGS take no specific position on this provision of the Stipulation.

5 B. AES Ohio shall continue to supply the Renewable Energy Credits required to cover its obligations under R.C. 4928.64 relating to the SSO load. C. AES Ohio shall continue its Standard Offer Rate (SOR) (Tariff Sheet No. G10) with its current rate design methodology, update process, and audit schedule, subject to the provisions in this Section III. 1. AES Ohio will continue recovery of uncollectible expenses associated with bypassable standard service offer rates through a bypassable component of the SOR. 2. AES Ohio will credit an amount equal to the bypassable uncollectible expense component of the SOR to customers at the same allocation as base distribution revenues through the Regulatory Compliance Rider on a nonbypassable basis. D. As part of the Grid Mod Implementation Update Group established in Case No. 18-1875-EL-GRD et al., AES Ohio agrees to discuss converting the results of its SSO competitive bid process into retail rates for SSO customers with on-peak and off-peak rates. With this group, AES Ohio agrees to discuss potential roadblocks or timing issues with deployment of such rates, including the time-of-use rate requirements in the Stipulation and Recommendation from that case, potential limitations of its current and planned billing systems, and deployment of smart meters. The Group will also discuss such issues as whether such an on-peak and off-peak pricing methodology for SSO customers should be on an opt-out

6 basis. Based upon the discussions in the Group, AES Ohio or another Signatory Party to this Stipulation may make a filing, unilaterally or jointly, for the Commission to consider an on-peak and off-peak SSO pricing proposal. All parties to the proceeding would reserve their rights to support or oppose any such proposal. IV. Distribution Investment Rider: A. AES Ohio shall implement a Distribution Investment Rider (“DIR”), as described in the testimony of AES Ohio Witness Adams, subject to the following conditions. B. Capital costs included in the DIR shall be those recorded in FERC Accounts 360 through 374, provided such costs are not collected from consumers elsewhere, such as but not limited to the Infrastructure Investment Rider. The calculation of the removal of these assets shall be included in the DIR filings. The DIR shall be computed by comparing the current rate base associated exclusively with plant accounts recorded in the FERC accounts noted above to the most recent rate base related to the same accounts as included in the overall rate base approved in the most recent base electric distribution rate case. The DIR revenue requirement shall be limited to (i) a return on distribution rate base using the weighted average cost of capital approved in the most recent base electric distribution rate case, grossed up for prevailing tax rates; (ii) depreciation expense; and (iii) property taxes on the incremental rate base (i.e., net

7 plant less Accumulated Deferred Income Taxes (ADIT)) accumulated since the date certain in the most recent electric distribution rate case, grossed up for commercial activity taxes. C. The beginning DIR date certain balance will include the balance of qualifying incremental investments placed in service through November 30, 2022. See Ex. 1. D. AES Ohio shall not recover operations and maintenance expense through the DIR, except as provided in Section IV(K) for DIR audit expense. E. The DIR shall be subject to the following revenue caps: 1. 2023: Cumulative amount of $2,350,000 per month effective with DIR commencement; 2. 2024: $38,400,000 annual cap3; 3. 2025: $49,400,000 annual cap4; and 4. 2026: Cumulative amount of $5,050,0005 per month until end of ESP term. 3 This DIR cap represents approximately 3.3% of base distribution revenue requirement from the most recent distribution rate case. 4 This DIR cap represents approximately 3.5% of base distribution revenue requirement from the most recent distribution rate case. 5 This DIR cap represents approximately 3.6% of base distribution revenue requirement from the most recent distribution rate case.

8 5. DIR revenue collected from consumers less than the cap in a given year shall not increase caps for future years. F. Reliability Performance 1. For purposes of Section IV(F)(3) below, the System Average Interruption Duration Index (“SAIDI”) performance goals are as follows: a) 2023: The SAIDI performance goal will be 103. b) 2024: The SAIDI performance goal will be 99. c) 2025: The SAIDI performance goal will be 96. 2. AES Ohio shall continue to be subject to Section 17(a) of the Stipulation and Recommendation that was approved in Case No. 18-1875-EL-GRD, et al. 3. SAIDI Performance Goal Effect on DIR Revenue Caps a) 2024 (i) If AES Ohio fails to achieve their annual SAIDI performance goal during the 2023 calendar year, then the revenue cap for 2024 will be decreased to $36,000,000. b) 2025

9 (i) If the Company fails to achieve their annual SAIDI performance goal during either the 2023 or 2024 calendar year, but achieves their SAIDI performance goal during the other calendar year, then the revenue cap for 2025 will be decreased to $47,000,000. (ii) If the Company fails to achieve their annual SAIDI performance goal during both the 2023 and the 2024 calendar years, then the revenue cap for 2025 will be decreased to $44,600,000. c) 2026 (i) If the Company fails to achieve their annual SAIDI performance goal during one calendar year between 2023 and 2025, but achieves their SAIDI performance goals during two other calendar years in that time frame, then the revenue cap for 2026 will be decreased to the cumulative amount of $4,850,000 per month until the end of the ESP term. (ii) If the Company fails to achieve their annual SAIDI performance goal during two calendar years between 2023 and 2025, but achieves their SAIDI performance goals during one other calendar year in

10 that time frame then the revenue cap for 2026 will be decreased to the cumulative amount of $4,650,000 per month until the end of the ESP term. (iii) If the Company fails to achieve their annual SAIDI performance goal for all years between 2023 through 2025, then the revenue cap for 2026 will be decreased to the cumulative amount of $4,450,000 per month until the end of the ESP term. G. Should AES Ohio fail to file a new base distribution rate case on or before December 31, 2025, then the DIR will sunset and the DIR rate shall be set to zero on January 1, 2026 except for truing up any over/under recovery of revenues. Should AES Ohio file a new base distribution rate case, DIR caps will be revised to reflect the updated base rates in that case, to go into effect upon Commission Order in that case. The DIR will then continue for the remainder of this ESP term, unless otherwise extended by the Commission. H. The DIR will be trued up for over/under recovery of revenues compared to the Company’s DIR revenue requirement. I. The recovery of incentive compensation in the DIR shall be treated in the same manner as such compensation is treated in the Company’s then- operative rate case.

11 J. AES Ohio shall include the Protected Excess ADIT the Company proposed to credit customers as an offset to the DIR revenue requirement per Case No. 19-0572-EL-UNC. The Company will comply with the normalization rules under Internal Revenue Code sections 167 and 168. In the event of new rulings or other guidance from the IRS or Department of the Treasury, whereby the treatment of the Protected Excess ADIT contemplated in this agreement would not comply with the normalization requirements, the parties agree to revisit the treatment and conform the treatment to act in accordance with the normalization rules at the next available opportunity. The parties also agree to revisit the treatment of Protected ADIT and Protected Excess ADIT in this agreement in the event that the allowed return in a future distribution rate case differs from the allowed return in the ESP in effect while the rates in such distribution rate case are effective. K. AES Ohio shall file quarterly updates on or about February 1st, May 1st, August 1st and November 1st, with rates charged to consumers being effective 60 days after filing unless otherwise suspended by the Commission. The filings shall be subject to review, as well as an annual audit. The audit shall either be conducted by Staff or by an independent third party under the direction of Staff. Expenses relating to such audits shall be deferred and collected from consumers through the DIR. Annual audits will include but not be limited to the following: 1. On-site inspections of new capital assets;

12 2. Tracking capital expenses from continuing property records, invoices, and other supporting documentation to the used and useful assets, as well as tracking used and useful assets to continuing property records, invoices, and other supporting documentation; 3. Verification of proper accounting and computation of annual property tax expense; 4. Verification of proper accounting and computation of state, local, and federal income tax expense, as well as taxes other than income; 5. Verification of proper accounting and computation of annual depreciation expense; 6. Verification of proper accounting for DIR revenues; and 7. Verification with FERC Form 1. L. AES Ohio shall solicit input from Signatory Parties in order to develop an annual work plan to emphasize proactive distribution maintenance that will focus spending on where it will have the greatest impact on maintaining and improving service reliability and resiliency of the grid for all consumers, and promoting equity for low-income communities. The plan shall include identification of those expenditures that will help reduce customers’ minutes interrupted. The work plan shall follow the same

13 format as the work plan attached to this Stipulation. See Ex. 2. AES Ohio shall update Staff quarterly on the expenditures made under the work plan and how those expenditures align with planned investments in individual reliability programs. AES Ohio shall file the work plan in the DIR docket by December 31 of each year. M. AES Ohio will notify Staff and Signatory Parties of any changes to the Company’s capitalization policy that materially affects the DIR and provide documentation to Staff and Signatory Parties of the revised policy. V. Proactive Reliability Optimization Rider A. AES Ohio shall implement a Proactive Reliability Optimization Rider (“PRO”), as described in the testimony of AES Ohio Witness Adams, subject to the following conditions. B. The PRO shall collect all prudently-incurred vegetation management expenses authorized for deferral on an annual basis, with no carrying costs, up to the caps identified by the Commission in Case Nos. 15-1830- EL-AIR and 20-1651-EL-AIR and not otherwise recovered in base distribution rates. C. Upon approval of this Stipulation by the Commission, the Company shall initially include for recovery in the PRO, the vegetation management deferral balance reflecting expenses incurred above the baseline set in Case No. 15-1830-EL-AIR in 2021 and 2022. The accumulated deferral

14 balance discussed in this section shall be recovered from customers evenly over a three-year (36-month) period. Pursuant to the Opinion and Order in Case No. 15-1830-EL-AIR, the deferral balance is not subject to carrying costs. D. AES Ohio shall file an annual update on or before March 31st of each year, with rates effective 60 days after filing unless otherwise suspended by the Commission. The annual update filing shall be subject to Commission review, audit, and reconciliation. The audit shall either be conducted by Staff or by a third party under the direction of Staff. If a third-party audit is conducted, the expense of such audits shall be deferred and recovered through the PRO. Such audit shall include a determination of whether expenditures are prudent in rendering utility service to customers. The Company will not file updates more frequently than once per year. E. In performing vegetation management, AES Ohio shall make reasonable efforts to return to a five-year trim cycle on all circuits. At the time of the annual audit, Staff will assess these efforts to determine if a reasonable degree of improvement has been made in this area. VI. Regulatory Compliance Rider A. AES Ohio shall implement a Regulatory Compliance Rider (“RCR”), as described in the testimony of AES Ohio Witness Donlon, subject to the following conditions.

15 B. The RCR shall recover the following amounts: 1. $28,269,736 of deferred OVEC costs, which reflects the balance of that deferral as of July 31, 2022, minus $660,616, which represents AES Ohio’s portion of a penalty assessed by PJM to OVEC owners.6 a) The OVEC deferral shall accrue carrying costs based upon a long-term debt rate of 4.40%, beginning at the time the costs were incurred, i.e. from October 1, 2014 through October 31, 2017 and from December 19, 2019 to December 31, 2019. b) To avoid double payment by consumers, the OVEC deferral identified in this Section, including carrying costs, were not and shall not be recovered either through the Company’s former Reconciliation Rider or current Legacy Generation Rider. 2. $13,796,923 of deferred Decoupling amounts through December 18, 2019, consistent with the decoupling methodology agreed to and approved as part of the Company’s overall distribution rates in Case No. 15-1830-EL-AIR. 6 OMAEG, Kroger, CUB, OEC, and OELC do not support the recovery of deferred OVEC costs, but agree to not oppose this provision of the Stipulation as a package. OMAEG, Kroger, CUB, OEC, and OELC’s non-opposition shall not be relied upon in any other forum or proceeding.

16 3. $6,315,489 of deferred Prior RCR costs. 4. Any Uncollectible Amounts that reflect a reconciliation to the amounts approved in base rates in Case No. 20-1651-EL-AIR upon implementation of those rates. 5. The deferral of O&M expenses associated with implementation of AES Ohio’s new Customer Information System upon demonstration of the functionality detailed in the Stipulation and Recommendation that was approved by the Commission in Case No. 18-1875-EL-GRD, et al., subject to a reasonableness and prudence review. 6. Regulatory assets later approved for collection from consumers by the Commission. AES Ohio must file an application with the Commission to request recovery of any future regulatory asset or liability from consumers through the RCR. Signatory Parties are not precluded from challenging any future requests to recover or credit a regulatory asset or liability through the RCR. C. The Company shall withdraw its application in Case No. 20-140-EL-AAM and will not recover or seek to recover the decoupling amounts at issue in that case in any future application or proceeding. D. AES Ohio shall provide the credit relating to uncollectible expense authorized by Section III(C)(2) through the RCR.

17 E. Costs allocated to non-residential customers shall be charged as a dollar per bill by tariff class, except that the secondary class charges shall be further differentiated by unmetered, single phase and three phase service. Costs allocated to residential customers shall be charged as a percentage of base distribution revenue. This rate design shall not affect the allocation of costs among tariff classes. F. To mitigate bill impacts, AES Ohio will extend recovery of the amounts authorized for recovery through the RCR in this proceeding over five years, including carrying costs at the Company’s then-authorized cost of long-term debt. Such going-forward carrying costs shall be capped at $4 million.7 VII. Storm Cost Recovery Rider A. AES Ohio shall continue its Storm Cost Recovery Rider (“SCRR”), subject to certain modifications, as described in the testimony of AES Ohio Witness Donlon. B. AES Ohio shall implement SCRR updates on April 1 and October 1 annually, with rates effective 60 days after filing unless otherwise suspended by the Commission. 7 The $4 million cap reflects estimated carrying costs over a three-year amortization schedule at 4.40% instead of five years.

18 C. The April 1 filing update shall be subject to annual Commission review, audit, and reconciliation. Such audit shall review the 12-month period ending September 30 of the prior year. The audit shall either be conducted by Staff or by an independent third party under the direction of Staff. If an independent third-party audit is conducted, the expense of such audits shall be deferred and recovered through the SCRR. Such audit shall include a determination of whether expenditures are prudent in rendering utility service to customers. Audit adjustments resulting from the annual audit shall be accounted for and captured in the filing next following a Commission Order issued pursuant to the results of the annual audit. D. AES Ohio shall not collect carrying charges from consumers on balances approved for recovery through the SCRR. VIII. Decoupling Rider A. AES Ohio withdraws the proposed Decoupling Rider as described in the testimony of AES Ohio Witness Teuscher, and agrees not to collect from any consumers decoupling revenues or lost revenues during the three year ESP term, notwithstanding any change in law, except for the agreed-upon amounts identified in Section VI(B)(2).

19 IX. Customer Programs Rider A. AES Ohio shall implement a Customer Program Rider (“CPR”) as described in the testimony of AES Ohio Witness Inman, subject to the following conditions. B. The CPR will recover the costs from residential consumers for the Low- Income Assistance Programs described in Section IX(E) and the Electric Vehicle (“EV”) programs described in Section IX(F). C. AES Ohio shall file annual updates of the CPR. The filings shall be subject to annual Commission review, audit, and reconciliation. The audit shall either be conducted by Staff or by an independent third party under the direction of Staff. If a third-party audit is conducted, the expense of such audits shall be deferred and recovered through the CPR. Audit adjustments resulting from the annual audit shall be accounted for and captured in the annual filing next following a Commission Order issued pursuant to the results of the annual audit. D. AES Ohio withdraws its requests in its Application relating to energy efficiency, demand-side management, and demand-response programs, but will implement the Low-Income Assistance Programs described in the next section. E. Low-Income Assistance Programs

20 1. Subject to the provisions of this Section, AES Ohio withdraws its request for collection of costs from consumers relating to the demand-response and behavior customer programs described in the testimony of AES Ohio Witness Houdek. AES Ohio shall collect from residential consumers an annual amount of $5.7 million to fund an annual budget for certain low-income-eligible programs (“Low-Income Assistance Programs”), which shall include (1) the Weatherization and Bill Payment Assistance Program, and (2) the Disadvantaged Communities Energy Initiative. 2. The administration of the Weatherization and Bill Payment Assistance Program will be bid out through a Request for Proposal process to select the best candidate under the criteria in this Section. The Staff and interested Signatory Parties and Non- Opposing Parties8 may provide input into the Request for Proposal scope of work definition. The winning bidder (third-party administrator) shall work with AES Ohio to administer the program with $3 million of the annual budget of the Low-Income Assistance Programs, including (1) $2.5 million of that annual budget dedicated to weatherization for residential customers modeled after the Ohio Home Weatherization Assistance Program, except that the income eligibility cap shall be 250% of the federal 8 Non-Opposing Parties" shall be those parties that sign this Stipulation as Non-Opposing Parties.

21 poverty level, and (2) $500,000 of that annual budget dedicated to low-income bill payment assistance, modeled after the Ohio Home Energy Assistance Program, with an income eligibility range of 175% to 250% of the federal poverty level. Any unused funds shall be rolled over to the next year until all funds associated with the three-year budget are exhausted. That third party will receive an administration fee for overseeing the weatherization portion of the program based on the percentage of the cost of that program; no fee will be paid to the third party for administering the bill payment assistance program. AES Ohio, Staff, Signatory Parties, and Non-Opposing Parties who are not selected as the third-party administrator will work with the third-party administrator to establish key performance indicators, and the third-party administrator shall submit a report to AES Ohio and Staff annually regarding its performance. AES Ohio may terminate any such agreement with the third party for cause, including but not limited to failure to achieve key performance indicators. a) AES Ohio shall select the third-party administrator by a competitive Request for Proposal conducted by the Company with input from Staff and interested Signatory Parties and Non-Opposing Parties. b) AES Ohio, with input from Staff and interested Signatory Parties and Non-Opposing Parties, shall establish minimum

22 criteria for bidders to be included in the Request for Proposal. c) The winning applicant shall be chosen at AES Ohio’s sole discretion. In choosing the winning applicant, AES Ohio may consider cost efficiency, track record of successful program delivery, utilization of Home Weatherization Assistance Program providers, LEEN experience and access, and any other criteria AES Ohio deems appropriate with no single criterion being conclusive. 3. AES Ohio shall provide $2.7 million of the annual budget of the Low-Income Assistance Program to support a Disadvantaged Communities Energy Initiative. Any unused funds shall be rolled over to the next year but all funds unspent by the end of the ESP term shall be returned to consumers. a) AES Ohio shall provide funding to three municipalities in the Company’s service territory with the highest per capita poverty rates. b) Municipalities seeking such funding shall submit an application explaining how any awarded funds will be used for energy-related purposes in Qualified Census Tracts to the benefit of low-income consumers residing in the area. The assistance provided to the low-income consumers shall

23 be used for low-income assistance, including but not limited to, utility bill payment assistance, reconnection fees, deposits to establish service due to an arrearage, and weatherization. Applicants must further explain how such funds shall promote social-economic benefits to the municipality and its residents. The winning applicant shall be chosen at AES Ohio’s sole discretion. c) AES Ohio will work with Staff and interested Signatory Parties and Non-Opposing Parties to develop key performance indicators, and AES Ohio shall submit a report to Staff annually regarding the municipalities’ performance. 4. AES Ohio shall not collect from consumers shared savings associated with the Low-Income Assistance Program. 5. AES Ohio agrees to meet with Commission Staff and other interested Signatory Parties and Non-Opposing Parties on an annual basis during the term of the ESP to discuss opportunities to weatherize properties of low-income customers. Discussion topics may include, but are not limited to: (1) ways for AES Ohio to streamline administrative and operational costs among funding sources so that Low-Income Assistance Program funds can reach more customers; (2) the average cost of weatherizing a home or

24 property for the Low-Income Assistance Program; (3) maximizing the number of recipients and beneficiaries of Low-Income Assistance Program funds; and (4) whether certain customer groups, such as persons with disabilities and the elderly, should be prioritized in the Low-Income Assistance Program. F. Electric Vehicles 1. Subject to the provisions of this Section, AES Ohio shall only implement the following EV program from its Application, which was further described in the testimony of AES Ohio Witness Elliot: the Residential Off-Peak Incentive Program. The program will encourage utilization of the distribution grid during off-peak hours. a) The Residential Off-Peak Incentive Program costs will be capped at $260,000 annually during the three-year ESP period and will be sunset at the end of the ESP term, unless otherwise extended. (i) Up to 20% of the total program costs eligible for recovery may be for outreach, labor, and evaluation of the Residential Off-Peak Incentive Program.9 9 The outreach authorized here is limited to notifying customers of the Residential Off-Peak Incentive Program. The eligible costs that may be recovered are limited to the direct costs, including labor, of implementing the Residential Off-Peak Incentive Program, including notification to customers, and the direct costs of evaluating the Residential Off-Peak Incentive Program and developing a proposal for the cost-based EV charging tariff.

25 (ii) Using the lessons learned from the Residential Off- Peak Incentive Program, the Company will propose a cost-based EV charging distribution service tariff to encourage off-peak charging for residential customers as part of its next EL-AIR or EL-SSO proceeding. Signatory Parties retain the right to take any position regarding such proposals. (iii) The costs of this program shall be allocated only to residential customers. 2. AES Ohio withdraws its request for collection of costs from consumers relating to the following EV programs, as described in the testimony of AES Ohio Witness Elliot: the Residential Managed Charging program, the Low-to-Moderate Income EV Subscription program, the C&I Managed Charging program, the C&I EVSE Rebates for Disadvantaged Communities program the C&I Fleet Solutions program, and the C&I EVSE Lease program. 3. In the Commission’s next review of Ohio Adm. Code Chapter 4901:1-9, AES Ohio will propose that for nonresidential customers, electric utilities shall be responsible for eighty percent of the total cost of line extensions for publicly-available EVSE, and that the customer shall be responsible for the remaining twenty percent of the total cost. Signatory Parties retain the right to take

26 any position regarding such proposal. AES Ohio will and other interested parties may encourage the Commission to commence review of line extension policies for publicly available EVSE within Ohio Adm. Code Chapter 4901:1-9 as part of the Commission Ordered Investigation in Case No. 22-1025. X. Green Energy Alternative Tariff10 A. AES Ohio shall implement an optional Green Energy Alternative Tariff, as described in the testimony of AES Ohio Witness Donlon, to offer agreements with mercantile customers to construct customer-sited renewable energy resources pursuant to R.C. 4928.47. B. Each agreement between AES Ohio and mercantile customers electing to take service under this tariff shall be submitted to the Commission for approval pursuant to R.C. 4928.47. XI. AES Ohio proposes to continue the following existing riders with their respective rate design methodologies, update processes, and audit schedules: A. Tax Savings Credit Rider; B. Infrastructure Investment Rider; C. Economic Development Rider; 10 IGS takes no specific position on this provision of the Stipulation.

27 D. Transmission Cost Recovery Rider (subject to the billing changes described in Section XVI, below); and E. Energy Efficiency Rider (pending final reconciliation). XII. As part of AES Ohio’s next distribution rate case application, the Company agrees to evaluate the cost to serve customers that have interconnected large onsite distributed generation (DG) facilities (larger than 500 kW of capacity), by current and proposed rate classes. The Company shall provide a list of customers included in the evaluation to the PUCO Staff, marked as confidential to protect customer identities and competitively sensitive information. The Company shall also provide the current revenues, the fully allocated cost to serve, and the net operating income for those customers during the test year period at current and proposed rates. Per the Commission's Opinion & Order in Case Nos. 20-1651-EL- AIR, et al., the Company will also “provide analysis of the impact of any rate change on distributed generation resources,” notably customers with large onsite DG facilities as described above. Based on this information, AES Ohio will also evaluate its existing cogeneration and small power production tariff and tariffs for net metering and consider any appropriate modification to those tariffs and/or the addition of a DG tariff. XIII. Residential Customer Education and Information A. In an effort to reduce disconnections, AES Ohio agrees to conduct educational outreach and marketing of utility assistance programs and

28 low-income energy efficiency programs. AES Ohio will prioritize its outreach into communities that have the highest percentage of disconnection notices issued. AES Ohio will explore outreach in multiple languages where appropriate and at local public events. On an annual basis, AES Ohio will provide to Signatory Parties and Non-Opposing Parties a performance metrics report on the outreach conducted, along with disconnection data in these communities. B. Upon receiving all necessary customer consent, AES Ohio will provide, without additional cost, CRES providers and third-party aggregators available customer data to allow them to enroll residential accounts to participate in the PJM ancillary services market, including but not limited to the customer’s peak load contribution. As part of the first meeting of the Grid Mod Implementation Update Group established in Case No. 18- 1875-EL-GRD et al. after approval of this Stipulation, AES Ohio will discuss what data may be available under this Section and when usable data will be available. Usable data sharing under this Section shall begin no more than one year from the date of such Grid Mod Implementation Update Group meeting, unless AES Ohio notifies the Grid Mod Implementation Update Group that more time is required to implement the program.

29 XIV. AES Ohio shall amend Tariff Sheet No. D26 to eliminate the $25 Reconnection of the Meter charge for customers with AMI meters who are reconnected remotely. XV. For any distribution rate case filed during the term of the ESP, the proposed equity component in AES Ohio's capital structure shall not exceed the capital structure approved in Case No. 20-1651-EL-AIR. Signatory Parties, other than AES Ohio, retain the right to take any position regarding such proposal. XVI. Transmission: AES Ohio will bill all non-residential customers taking service at primary voltage and above, and any non-residential customers taking service at secondary voltage that opt-in, for all TCRR demand charges on the basis of their Network Service Peak Load (NSPL). Billing based on NSPL shall be implemented starting June 2025. Secondary customers who opt-in to TCRR charges billed on the basis of their NSPL may not opt-out within two years of opting-in. This change in transmission billing shall not shift any transmission costs to residential customers. AES Ohio will continue its existing TCRR Opt-Out Pilot program until the NSPL billing change is effective, at which point the program will cease. Enrollment in the existing TCRR Opt-Out Pilot program shall be open to Signatory Parties (including their members, affiliate members, customers, or members’ customer) served at secondary voltage or primary voltage and above on an opt-in basis. Enrollment in the existing TCRR Opt-Out Pilot

30 program shall be capped at 50 customers. For residential customers, billing for the TCRR shall continue to operate as it does now. XVII. Economic Development Incentive A. The Economic Development Incentive, Economic Development Incentive Tariff and the associated Economic Development Rider proposed in the Application and described in the Testimony of AES Ohio Witness Inman, pp. 4-5 are approved and shall be modified as follows: 1. AES Ohio will enter into a Service Agreement with an existing or new non-residential customer with a demand of 500 kW or greater at a single site to establish an Economic Development Incentive to support the development of new or expanded business or manufacturing facilities in AES Ohio’s service territory. For customers served at Secondary and Primary voltage level of service, the incentive will be implemented through the following percentage reductions of the customer’s monthly billed demand, for base distribution service only, for two years, based on the amount of capital invested by the customer in the new or expanded facilities or the load growth in the new or expanded facilities. For customers served at Primary-Substation and High Voltage level of service, the incentive will be implemented through the following percentage reductions of the customer’s monthly billed demand, for base distribution service and transmission service only, for two

31 years, based on the amount of capital invested by the customer in the new or expanded facilities or the load growth in the new or expanded facilities. a) >$20 million of investment or load growth of >500 kW: 50% b) >$30 million of investment or load growth of >750 kW: 55% c) >$40 million of investment or load growth of >1,000 kW: 60% d) >$50 million of investment or load growth of >1,250 kW: 65% e) >$60 million of investment or load growth of >1,500 kW: 70% 2. To qualify, the construction work associated with the new or expanded facilities must commence after this ESP is approved by the Commission and must be substantially completed within three years of commencement of construction. The Service Agreement to establish the incentive may be made at any time prior to the substantial completion of construction and must include reasonable evidence of the expected capital investment or load growth.

32 3. Within sixty (60) days of the substantial completion of construction of the new or expanded facilities, the customer must submit to AES Ohio reasonable evidence of the amount of capital investment made by the customer or load growth attributable to the new or expanded facilities. The discount will take effect in the first full billing cycle following the date of this submission and will remain in effect for twenty-four (24) months. 4. The Economic Development Incentives will be collected from all consumers through delta revenues in the Economic Development Rider. AES Ohio agrees to a cap of $1.50 per year per residential customer, $10.00 per year per customer served at secondary voltage level, and $750.00 per year per customer served at primary voltage level and above on the amount of delta revenue collected relating to these incentives.11 5. AES Ohio shall provide any Service Agreements entered under this Section to Staff on a confidential basis. 11 These customer bill caps represent approximately $1.6 million of delta revenue per year.

33 XVIII. AES Ohio agrees to meet with the Ohio Hospital Association (“OHA”) at least once per year to discuss opportunities that enhance reliability and resiliency for hospitals in its service territory. XIX. AES Ohio agrees to extend the waiver of the Contract Capacity Charge related to Redundant Service (“Alternate Feed Service”) for the City of Dayton and all OHA members until (1) the term of the ESP 4 ceases or (2) AES Ohio ceases recovery through the Infrastructure Investment Rider, whichever event occurs later. This waiver shall be applied to the City of Dayton and all OHA members regardless of whether or not these members are currently paying Alternate Feed Service charges or whether the City of Dayton or these OHA members require Alternate Feed Service in the future. Revenue that is not collected due to this waiver shall not be collected from other customers. XX. Significantly Excessive Earnings Test A. The threshold for determining whether the Company had significantly excessive earnings under R.C. 4928.143(F) in 2023, 2024, and 2025 shall be a return on equity of 13%. AES Ohio agrees not to request to offset any excessive earnings under R.C. 4928.143(F) in those years with future committed investments. AES Ohio agrees to credit any significantly excessive earnings in those years to consumers within 12 months of an Order finding that the Company had significantly excessive earnings.

34 XXI. Consumer Hardship Bill Payment Assistance A. AES Ohio shall contribute $50,000 per year for three years of shareholder funds to the AES Ohio Gift of Power program following approval of this Stipulation. Funds not distributed shall be rolled over to the following year until funds are exhausted. XXII. AES Ohio shall convene a working group open to all Signatory Parties, to meet at least three times before filing its next base distribution rate case, to discuss and design a potential non-residential rate structure to collect the costs of providing electric service to customers with low energy utilization, including but not limited to EV charging stations. The working group shall consider a variety of rate designs either currently in effect in Ohio or elsewhere. Based on the working group’s discussions, AES Ohio will propose an appropriate rate structure for such customers in that rate case. XXIII. Staff will issue a Request for Proposal to review data associated with uncollectible expense recovery. Specifically, the consultant shall conduct a review of: A. Customer account billing records for both SSO and CRES customers in which balances were written off during the 12 months prior to the signing of the Stipulation; B. The Company’s collection and disconnection practices; C. The process for applying partial payments; and

35 D. Any other records or information deemed appropriate. Costs associated with this review shall be recoverable through the RCR on a non- bypassable basis. XXIV. The Signatory Parties recommend that the Commission find that this electric security plan, as reflected in the Application and modified by this Stipulation, including its pricing and all other terms and conditions, including any deferrals and any future recovery of deferrals, is more favorable in the aggregate as compared to the expected results that would otherwise apply under Section 4928.142 of the Revised Code. XXV. AES Ohio will work collaboratively with the City of Dayton to support the interconnection of any solar project at the Valleycrest Superfund site. XXVI. Rate Case Items A. Pursuant to the Opinion and Order in Case No. 20-1651-EL-AIR: 1. AES Ohio agrees to eliminate the switching fees in Tariff Sheet Nos. D34 and G9. AES Ohio may request to reimplement switching fees in a future rate case or other proceeding. 2. AES Ohio agrees to implement its proposal for the Low-Load Factor Charge (formerly known as the Maximum Charge Provision) as described in its January 13, 2023 Application for Rehearing in Case No. 20-1651-EL-AIR to revise the components

36 of the Low-Load Factor Charge (i.e., base distribution rates and the TCRR) to evenly phase-in rates to gradually target customers with approximately 10% load factors, so that customers with approximately the following load factors would continue to be billed under the Low-Load Factor Charge: a) Year 1: 16% b) Year 2: 12% c) Year 3: 10%. XXVII. Other Provisions: A. The Stipulation addresses a variety of complex issues that, absent this agreement, would have been resolved through several complex, protracted, and litigated proceedings. The Stipulation contains the entire agreement among the Signatory Parties and reflects a complete settlement of all proposals, issues, comments, and objections in these proceedings. The Signatory Parties will support this Stipulation, if it is contested, and no Signatory Party shall oppose an application for rehearing designed to defend the terms of the original unmodified Stipulation. The Signatory Parties agree that this Stipulation advances the public interest and urge the Commission to adopt it. B. Except for purposes of enforcing the Stipulation or establishing that its terms and conditions are lawful, neither the Stipulation nor the information and data contained therein or attached hereto shall be cited as precedent in any proceeding for or against a Signatory Party, if the

37 Commission approves this Stipulation. The Stipulation is submitted for the purpose of resolving only the proceedings identified herein and does not reflect the position that any individual Signatory Party may take as to any individual provision of the Stipulation, standing alone. Rather, the Stipulation reflects an overall outcome that reflects a compromise and balancing of competing interests and does not reflect the position that any one of the Signatory Parties would have taken on any individual issue. As such, acceptance of any provision within this Stipulation shall not be cited by any party or the Commission in any case to state or imply that any Signatory Party agrees with any specific provision of the settlement. C. This Stipulation is expressly conditioned upon its adoption by the Commission in its entirety and without material modification. Each Signatory Party has the right in its sole discretion to determine whether the Commission’s approval of this settlement contains a material modification. If the Commission rejects or materially modifies all or any part of this Stipulation, any Signatory Party shall have the right, within thirty days of issuance of the Commission’s Order, to file an application for rehearing. The Signatory Parties agree that they will not oppose or argue against any other Signatory Party’s application for rehearing that seeks to uphold the original unmodified Stipulation. If the Commission does not adopt the Stipulation without material modification upon any rehearing ruling, then within thirty days of such Commission rehearing ruling any Signatory Party may terminate its Signatory Party status and

38 withdraw from the Stipulation by filing a notice with the Commission. No Signatory Party shall file a Notice of Withdrawal without first negotiating in good faith with the other Signatory Parties to achieve an outcome that substantially satisfies the intent of the Stipulation. If a new agreement achieves such an outcome, the Signatory Parties will file the new agreement for Commission review and approval. If the discussions to achieve an outcome that substantially satisfies the intent of the Stipulation are unsuccessful, and a Signatory Party files a Notice of Withdrawal, then the Commission will convene an evidentiary hearing to afford that Signatory Party the opportunity to contest the Stipulation by presenting evidence through witnesses, to cross-examine witnesses, to present rebuttal testimony, and to brief all issues that the Commission shall decide based upon the record and briefs. If the discussions to achieve an outcome that substantially satisfies the intent of the Stipulation are successful, then some or all of the Signatory Parties shall submit the amended Stipulation to the Commission for approval after a hearing if necessary. If the Commission adopts this Stipulation without material modification, then the Company agrees to waive its statutory right under R.C. 4928.143(C)(2)(a) to withdraw its application upon any subsequent modification by the Commission on remand from the Supreme Court of Ohio. D. Unless a Signatory Party exercises its right to withdraw from the Stipulation and terminate its status as a Signatory Party, each Signatory

39 Party agrees to and will support and/or not oppose the reasonableness of the Stipulation before the Commission, and to cause its counsel to do the same, and in any appeal from the Commission’s adoption or enforcement of the Stipulation in which it participates. E. The Signatory Parties agree that the settlement and resulting Stipulation are a product of serious bargaining among capable, knowledgeable parties. This Stipulation is the product of an open process in which all parties were represented by able counsel and technical experts. The Stipulation represents a comprehensive compromise of issues raised by parties with diverse interests. The Signatory Parties believe that the Stipulation that they are recommending for Commission adoption presents a fair and reasonable result. F. AES Ohio may offer its testimony and exhibits filed in these proceedings as further evidentiary support for this Stipulation, where they are consistent with the Stipulation, and where they are not consistent they may be offered to show that good faith bargaining occurred that resulted in a lawful and reasonable outcome, which testimony shall not be subject to cross examination by the Signatory and Non-Opposing Parties. AES Ohio will file testimony in support of this Stipulation. Nothing herein prohibits any Signatory Party or Non-Opposing Party from filing testimony or submitting evidence in support of the Stipulation.

40 G. The Signatory Parties agree that the settlement, as a package, benefits AES Ohio’s customers and is in the public interest. The Signatory Parties agree that the settlement package does not violate any important regulatory principle or practice. IN WITNESS THEREOF, the undersigned Signatory Parties agree to this Stipulation and Recommendation this 10th day of April, 2023. The undersigned Signatory Parties request that the Commission issue an Opinion and Order approving and adopting this Stipulation. THE DAYTON POWER AND LIGHT COMPANY D/B/A AES OHIO By: /s/ Jeffrey S.
