CONTRACTS, DEPOSITS AND ADVANCE PAYMENTS

4. CONTRACTS The Company reserves the right to require non-residential customers to sign a written contract indicating the rate for electric service and to require a contract term which, in the judgment of the Company, is sufficient to justify the cost of any facilities installed for the exclusive use of the customer and to compensate the Company for other incremental costs of Nonstandard Service. Customers who have facilities extended for their exclusive use will be permitted to purchase electricity from an EGS according to the provisions of direct access and 66 Pa.C.S. § 2807. Extension of such facilities will not be conditioned on the customer’s agreement to purchase supply from the Company. Receipt of electric service by any entity, however, shall constitute the receiver a customer of the Company, subject to its rules and regulations, whether service is based upon contract, agreement, accepted signed application or otherwise. The customer shall notify the Company, in advance of receipt of electric service, of the customer's name, address to which the electricity is to be delivered, the address to which the bill is to be mailed, the date delivery of electricity is to commence, and provide information requested by the Company regarding the customer's credit standing. The customer shall notify the Company to cancel electric service and the customer shall be responsible for payment for all electric charges until the customer has so notified the Company to cancel electric service.

The Company at its sole discretion may enter into special contracts for electric service with industrial or commercial customers to address changing business needs, operating conditions or less expensive competitive alternatives for energy. If requested by the Company, the customer shall provide to the Company, on a confidential basis, all information, records and financial analysis necessary to evaluate the customer’s request for a special contract.

ORIGINAL PAGE NO. 10

RULES AND REGULATIONS - (Continued)

CONTRACTS, DEPOSITS AND ADVANCE PAYMENTS - (Continued)

4. CONTRACTS – (Continued)

Terms and conditions of service will be mutually agreed upon by the Company and the customer and included in a signed contract, which will be filed with the Public Utility Commission. The Company at its sole discretion may request Public Utility Commission approval. The terms of the agreement will be confidential upon filing with the Commission. Rates established under special contracts will be sufficient to recover, at a minimum, all appropriate incremental costs. Any special contracts written to become effective on or after January 1, 2007, shall apply only to charges for the distribution service provided by the Company.

The contract shall contain all terms and conditions and the rates and charges to be paid for electric service.

The contract shall be for a period of no less than one (1) year and no greater than ten (10) years.

The contract will be terminated by the Company if the Company charges are not paid when due as specified in Tariff Rule No. 21, before the addition of the Late Payment Charge. Upon termination of the contract under these conditions, the regular electric tariff rates will be applied to electric service rendered from that point forward. A new special contract will not be made available to a customer whose previous special contract was terminated because of failure to pay bills as specified in Tariff Rule No. 21.

For contracts that contain provisions governing the customer’s rights under direct access, the Company will unbundle the customer’s contract and the customer will be eligible to obtain electricity from an EGS only in accordance with the terms and conditions of the customer’s contract. Upon expiration of their contract, special contract customers will default to Rider No. 9 – Day-Ahead Hourly Price Service.

5. DEPOSITS AND ADVANCE PAYMENTS The Company reserves the right to require a cash deposit from applicants taking service for a period of less than thirty (30) days, in an amount equal to the estimated gross bill for Company charges, including applicable EGS charges, for such temporary service. The gross bill for Company charges shall include all fixed, demand and energy charges for Company charges in accordance with the applicable tariff. Deposits may be required from all other applicants when creditworthiness has not been established. A deposit may also be required from existing customers when such customer's credit standing is impaired by delinquent payments of any two (2) consecutive electric bills for Company charges or three (3) or more electric bills for Company charges within the preceding twelve (12) months, or as a condition to the reconnection of service or failure to comply with a payment arrangement. Company charges include the customer’s EGS receivables that are purchased by the Company. The Company shall not require an applicant or customer who is confirmed to be eligible for a customer assistance program to provide a cash deposit.

The Company, at its discretion, may deem a non-residential customer or applicant to be not creditworthy. Evidence that such a customer or applicant is not creditworthy may include, but shall not be limited to, where the customer or applicant: (i) is insolvent (as evidenced by a credit report prepared by a reputable credit bureau or credit reporting agency or public financial data, liabilities exceeding assets or generally failing to pay debts as they become due);

(ii) has a class of publicly-traded debt outstanding that is rated to be below investment grade; (iii) has tendered two

(2) or more checks that are subsequently dishonored by a payee according to 13 Pa.C.S. § 3502, within the last twelve (12) billing cycles; or (iv) has had an account balance at least sixty (60) days in arrears within the last twelve

(12) billing cycles. The Company may require non-residential customers or applicants to provide financial data as reasonably necessary for the Company to assess their creditworthiness.

ORIGINAL PAGE NO. 11

CONTRACTS, DEPOSITS AND ADVANCE PAYMENTS - (Continued)

5. DEPOSITS AND ADVANCE PAYMENTS - (Continued)

The Company may also use an applicant or customer credit score from a third party credit agency as a means to establish creditworthiness. The credit score in the report will be based in part on previous utility billing history and will use a commercially recognized credit scoring methodology that is within the range of generally accepted industry practices to determine whether security or advance payments are required to establish service. The Company may request a government issued photo ID of any applicant to verify the application.

Where the Company requires a deposit, the amount of the deposit will be based on Company charges in an amount that is equal to one-sixth of the applicant’s estimated annual bill or one-sixth of the actual average annual bill for existing customers at the premises, provided that the minimum deposit amount for non-residential customers shall be $250.00. In accordance with Commission regulations, the deposit shall be payable during the 90-day period commencing when the Company determines a deposit is required whether for new service or for deposits required upon reconnection of service as described in Rule No. 40. Failure to pay a required deposit within the time period noted above may result in termination of service consistent with Commission regulations. An applicant or existing customer may furnish a third party guarantor in lieu of a cash deposit, with the provision of a written guaranty setting forth the terms therein. The guarantor will be responsible for all missed payments of the applicant or customer.

The Company will pay interest on residential cash deposits computed at the simple annual interest rate determined by the Commonwealth of Pennsylvania’s Secretary of Revenue. The interest rate in effect when the deposit is required to be paid shall remain in effect until the later of the date the deposit is refunded or credited or December

31. On January 1 of each year, the new interest rate for that year will apply to the deposit. For all other cash deposits, the Company will pay interest at the lower of the average of 1-year Treasury Bills for September, October and November of the previous year beginning May 1, 1995 and January 1, 1996 and each year thereafter, or six percent per annum without deduction for any taxes thereon, provided that interest accrued prior to April 14, 1995 shall be calculated at 6%. On deposits held for more than one year, accrued interest will be paid at the end of each anniversary year. Upon the return of a deposit, any unpaid interest accrued thereon will be paid.

Deposits secured from a residential applicant or customer shall be returned to the depositor when a timely payment history has been established. A timely payment history is established when a customer has paid undisputed bills in full and on time for twelve (12) consecutive months. Should a customer become delinquent prior to establishing a timely payment history, the Company may deduct the outstanding balance from the deposit. Deposits secured from other than residential customers shall be returned to the depositor upon annual review provided such depositor shall have paid undisputed bills during those consecutive twelve (12) months without having service terminated and without having paid the bill subsequent to the due date so long as the customer is not currently delinquent. Payment of any disputed bill, where the payment is withheld beyond the due date set forth on the face of the bill at issue and the dispute over which is terminated substantially in favor of the customer, shall be made by the customer within fifteen (15) days following the termination of that dispute in order to be deemed timely. Where service is discontinued, the deposit and unpaid interest accrued thereon to the date of discontinuance of service, less the amount of all bills due the Company, will promptly be paid to the customer.

For purposes of all of the provisions of this Rule No. 5, when a customer resides at a place of business or commercial establishment, legitimately served pursuant to a commercial or industrial rate schedule, that is not a residential dwelling unit attached thereto, the customer is not thereby entitled to any of the protections in the Pennsylvania Public Utility Code or the Commission's regulations implementing the Pennsylvania Public Utility Code, or to any of the provisions of these rules or this Tariff, that apply exclusively to deposits for residential customers.

ORIGINAL PAGE NO. 12

PAYMENT OF OUTSTANDING BALANCE

5.1 PAYMENT OF OUTSTANDING BALANCE As a condition of the furnishing of service to an applicant or customer, the payment of any outstanding account amount with the Company for which the applicant or customer is legally responsible is required. The Company may require the payment of an outstanding balance or portion of an outstanding balance as a condition of furnishing service if the applicant or customer resided at the property for which service is requested during the time the outstanding balance accrued and for the time applicant/customer resided there, not exceeding four (4) years from the date that the last bill rendered, except for fraud or theft. The Company may require the applicant or customer to provide, and may establish that an applicant or customer previously resided at a property for which residential service is requested through the use of a mortgage, deed or lease or a commercially available consumer credit reporting service. In addition, the Company may also require and use valid government-issued photo identification, and may use billing/mailing records, court records, factual reporting and Company records where the applicant or customer was listed as a spouse or an occupant of a premise, such as on a customer assistance program enrollment form, a payment arrangement, a power of attorney or authorization or a medical certification.

INSTALLATION OF SERVICE

6.

Any service via lines supported by a customer-owned pole or structure

Point of service line connection to the first customer-owned pole or structure to which Company facilities connect

The Company reserves the right to designate an alternative Service Point, at its sole discretion, for customers with atypical or specialized service configurations, or customers participating in the Company’s EV ChargeUp pilot program for electric vehicle charging stations.

The Company shall not be required to install or maintain any conductors, meter base, equipment or apparatus except meter and meter accessories, as applicable, beyond the Service Point.

7. SUPPLY LINE EXTENSIONS

A. Definitions

For the purposes of this rule, the following definitions are applicable:

(1) Contractor cost - The amount paid to a contractor for work performed on a line extension.

ORIGINAL PAGE NO. 14

7. SUPPLY LINE EXTENSIONS – (Continued)

A. Definitions – (Continued)

(2) Direct labor cost - The pay and expenses of public utility employees directly attributable to work performed on line extensions, but does not include construction overheads or payroll taxes, workers' compensation expenses, or similar expenses.

(3) Direct material cost - The purchase price of materials used for a line extension, but does not include the related stores expenses. In computing direct material costs, proper allowance should be made for unused materials recovered from temporary structures, and discounts allowed and realized in the purchase of materials.

(4) Total construction cost - The contractor cost, direct labor cost, direct material cost, stores expense, construction overheads, payroll taxes, workers' compensation expenses, or similar expenses.

(5) Current Year - For purposes of calculating a revenue guarantee, current year shall be each consecutive period of twelve (12) calendar months following the date permanent electric delivery service was first provided to a customer.

(6) Income Tax - Federal and State tax relating to the tax liability of contributions in aid-of-construction (“CIAC”).

B. Overhead Areas

(1) In areas where the existing supply lines are overhead, the Company will construct and maintain extensions of all single-phase overhead supply lines operating at 23,000 volts or less to approximately 100 feet within the customer's property line without a guarantee of revenue.

(2) In areas where the existing supply lines are overhead, the Company will construct and maintain extensions of all three-phase overhead supply lines, operating at 23,000 volts or less, which are usable as a part of its general supply system without a guarantee of revenue.

When the three-phase supply line extension is to supply service exclusively to a single customer, such a supply line will be extended to the customer's property line only if a guarantee of revenue is provided by the customer over a period of five years which is sufficient to recover the actual total construction cost of the three-phase overhead line extension, less the estimated total construction cost for an equivalent single-phase overhead line extension. In the event that a revenue guarantee is not sufficient to recover the estimated total cost of the construction, or if the Company determines that the extension is speculative, or the customer represents a credit risk, the Company may require an up-front contribution in aid of construction (CIAC) from the customer to recover the total cost of construction. A customer may choose the option to make a CIAC rather than utilize a revenue guarantee. The Company will consider financing alternatives, such as a letter of credit or other payment arrangements, in lieu of a CIAC when appropriate. Any additional CIAC payment required will include the related income tax.

ORIGINAL PAGE NO. 15

7. SUPPLY LINE EXTENSIONS - (Continued)

C. Underground Areas

(1) In areas where the existing supply lines are underground outside the limits of a residential development covered by Tariff Rule 13.2, the Company will construct and maintain extensions of all single-phase underground supply lines operating at 23,000 volts or less which are usable as part of its general supply system without a guarantee of revenue. When the single-phase supply line extension is to supply electricity exclusively to a single customer, such a supply line will be extended to the customer's property line only if a guarantee of revenue is provided by the customer, over a period of five years which is sufficient to recover the actual total contractor cost, direct labor cost and direct material cost for the full length of the single-phase underground line extension, less the estimated total contractor cost, direct labor cost, and direct material cost for an equivalent single-phase overhead line extension. In the event that a revenue guarantee is not sufficient to recover the estimated total cost of the construction, or if the Company determines that the extension is speculative, or the customer represents a credit risk, the Company may require an up-front contribution in aid of construction (CIAC) from the customer to recover the total cost of construction. A customer may choose the option to make a CIAC rather than utilize a revenue guarantee. The Company will consider financing alternatives, such as a letter of credit or other payment arrangements, in lieu of a CIAC when appropriate. Any additional CIAC payment required will include the related income tax.

(2) In areas where the existing supply lines are underground outside of the limits of a residential development covered by Tariff Rule 13.2, the Company will construct and maintain extensions of all three-phase underground supply lines operating at 23,000 volts or less which are usable as part of its general supply system without a guarantee of revenue. When the three-phase supply line extension is to supply service exclusively to a single customer, such a supply line will be extended to the customer's property line only if a guarantee of revenue is provided by the customer over a period of five years which is sufficient to recover the actual total construction cost of the three-phase underground line extension, less the estimated total construction cost for an equivalent single-phase overhead line extension. In the event that a revenue guarantee is not sufficient to recover the estimated total cost of the construction, or if the Company determines that the extension is speculative, or the customer represents a credit risk, the Company may require an up-front contribution in aid of construction (CIAC) from the customer to recover the total cost of construction. A customer may choose the option to make a CIAC rather than utilize a revenue guarantee. The Company will consider financing alternatives, such as a letter of credit or other payment arrangements, in lieu of a CIAC when appropriate. Any additional CIAC payment required will include the related income tax.

D. Rights-of-Way

Before construction of a line extension, satisfactory rights of way and other necessary permits must be granted to the Company for the construction of the supply line extension along the route selected by the Company. The customer agrees to pay the Company any initial and recurring rights-of-way or license fees in excess of an amount normally incurred by the Company in constructing and maintaining the supply line extension.

E. Revenue Guarantees

The revenue guarantee amount shall be the estimated combined cost of (i) the line extension and

(ii) other new Company facilities necessary to serve the customer. The annual revenue guarantee amount shall be the revenue guarantee amount, divided by the number of years in the guarantee period. The annual revenue guarantee amount will be reviewed yearly and will be adjusted to the minimum charges as provided in the applicable rate schedule on the following basis:

(1) When the total of the monthly Company delivery charges at the end of the current year is less than the annual revenue guarantee amount, a payment equal to the difference plus the related income tax where applicable shall be immediately due and payable.

(2) When the total of the monthly Company delivery charges within the number of years in the guarantee period equals or exceeds the revenue guarantee amount, no further payments toward the revenue guarantee amount are required. Any prior payments in excess of the revenue guarantee amount, except for otherwise-applicable charges for electric service, will be refunded with accrued interest.

(3) If an additional customer is served from the line extension, the revenue guarantee amount will be reduced to the cost of the line extension which is used exclusively to serve the single customer. If the cost of the line extension to serve the new customer would increase the revenue guarantee amount for an existing customer, the extension shall be considered as a new line extension.

(4) In the event the customer discontinues or cancels service before the end of the guarantee period, the balance of the revenue guarantee amount plus the related income tax where applicable shall be immediately due and payable.

F. Contributions in Aid of Construction

The Contribution in Aid of Construction (CIAC) will be refunded to the customer over the five-year revenue guarantee period to the extent that the revenue from the customer satisfies the revenue guarantee.

(1) When the total of the monthly Company delivery charges at the end of the current year is greater than or equal to one-fifth of the CIAC, a refund of one-fifth of the CIAC will be made to the customer.

(2) When the total of the monthly Company delivery charges at the end of the current year is less than one-fifth of the CIAC, a refund of one-fifth of the CIAC less the revenue shortfall will be made to the customer.

F. Contributions in Aid of Construction – (Continued)

(3) At the end of the five-year revenue guarantee period, a final reconciliation of delivery charges during the period will be made against the CIAC. If the total delivery charges paid exceed or equal the original CIAC, any remaining CIAC will be returned to the customer. If the total delivery charges paid are less than the original CIAC, the remaining CIAC will be retained by the Company.

8. NONSTANDARD SERVICE The Company reserves the right to require a customer or applicant for service to pay the cost, including the related income tax, of any special installation necessary to meet the unusual requirements of the customer or applicant for service, including, but not limited to:

(1) service at other than standard voltages,

(2) service for intermittent, unbalanced or fluctuating loads, which, in the Company’s sole judgement, would not generate sufficient revenue to recover the installation costs of the required facilities,

(3) service for loads that will be continuous but that will generate minimal usage, and which, in the Company’s sole judgement, would not generate sufficient revenue to recover the installation costs of the required facilities,

(4) service for loads that will require provision of closer voltage regulation than required by standard service,

(5) redundant service requested by the customer and not required by the Company, and

(6) service routings or configurations that deviate from the Company’s standard construction standards described in the Company's "Electric Service Installation Rules," or that would otherwise necessitate significant construction of new Company facilities.

The customer or applicant shall pay all costs to the Company of performing environmental assessments, including, but not limited to, the cost of consultants utilized by the Company, the cost of removal and disposal of contamination, waste or hazardous materials or dealing with other adverse environmental conditions associated with either the initial installation, modification, repair, maintenance or removal of service facilities.

The Company may decline to provide Nonstandard Service where, in the Company’s sole judgment, it would not be commercially, operationally, and/or technically reasonable to provide such service.

9. RELOCATIONS OF FACILITIES

A. Pole Removal or Relocation for Residential Customers

When requested by a residential property owner who is not otherwise entitled to receive condemnation damages to cover the cost of the pole removal or relocation or who is not requesting a pole removal or relocation as the result of damages caused by the intentional or negligent conduct of any party, the Company will when it is practicable, subject to the execution

9. RELOCATIONS OF FACILITIES – (Continued)

A. Pole Removal or Relocation for Residential Customers – (Continued) and receipt of required easements, licenses or municipal permits, remove or relocate a pole or poles and associated attachments, upon receipt, in advance, of the Company's estimated contractor or direct labor and direct material costs associated with the particular pole removal or relocation, less any maintenance expenses avoided as a result of the pole removal or relocation.

For purposes of this Rule, the following definitions are applicable:

(1) Contractor costs - Amount paid by the utility to a contractor for work performed on a pole removal or relocation.

(2) Direct labor costs - Includes pay and expenses of public utility employees directly attributable to work performed on pole removals or relocations. Excludes payroll taxes, workmen's compensation, similar items of expense and construction overhead costs.

(3) Direct materials costs - Includes the purchase price of materials used in performing a pole removal or relocation and excludes the related stores expenses. Proper allowance shall be made for unused materials, and materials recovered from temporary structures, and for discounts allowed and realized in purchase of materials.

(4) Income tax - Federal and State tax relating to the tax liability of contributions in aid-of-construction.

B. Meter Relocation for all Customers

Pursuant to Act 129 of 2008; the Commission’s Smart Meter Procurement and Installation

Implementation Order entered June 24, 2009, at Docket No. M-2009-2092655; and Duquesne Light’s Smart Meter Procurement and Installation Plan, approved in relevant part by Order entered April 7, 2017, at Docket No. P-2015-2497267; smart meter(s) conforming to Company standards must be installed at each metered service premises. Customers may not decline smart meter installation for any reason. Instead, as their sole remedy, customers may designate an alternative location on the premises for the smart meter. The Company shall relocate the smart meter to such alternative location where (i) the relocation (including associated customer service equipment) conforms to the Company’s “Electric Service Installation Rules” (see Rule No. 6) and the National Electric Safety Code, as determined by the Company in its sole judgment; (ii) the relocation can be readily, safely, and reliably interconnected to the Company’s facilities, as determined by the Company in its sole judgment; (iii) the customer provides any easements, permits, or other governmental or third-party approvals the Company deems necessary to accommodate such relocation; and (iv) the Company receives, in advance, payment for the Company’s estimated total direct and indirect costs including the related income tax of such relocation.

C. Other Company Facilities for all Customers

When requested or required by the action of a customer or a third party, relocation of Company facilities, except those covered under Section A of this Rule, will be performed by the Company upon receipt, in advance, of the Company's estimated total direct and indirect costs including the related income tax of such relocations from the customer or such third party. The Company may waive charges under this rule if, in the Company's judgment, the location of the Company's existing supply line and/or service line on the customer's property restricts the growth of the customer's operations and the potential increase in the Company's revenues.

10. ONE SERVICE OF A KIND Only one service of each type as to voltage and phase will be provided to a customer under one contract; provided, however, that when, in the judgment of the Company, compliance with Rule No. 17, Fluctuations and Unbalances, may be most economically effected by establishing a separate service connection for a portion of the customer's load, such separate service connection may, at the option of the customer, be combined, notwithstanding similarity as to voltage and phase, with other service connections under a single contract for the customer's entire electric delivery service requirements at the affected location. Electric service at different premises, regardless of voltage or phase, shall never be combined for billing under one account for the purpose of reducing Company charges.

11. METER SUPPORTS The customer shall provide on the premises, at a location satisfactory to the Company, proper space, supports, and enclosures for metering equipment.
