3 Introduction Company approval of connecting a generator to its distribution system is required. The information in this document will guide a customer with an inverter-based distributed generation (DG) resource < 50 kw on the requirements and process to safely interconnect it to the AEP Ohio distribution system. Our Minimum Requirements for Distribution System Interconnection are on page 2 and based on Chapter 4901:1-22 Interconnection Services of the Ohio Administrative Code (OAC). The OAC governs the DG interconnection requirements for customers and the investor-owned electric utilities in Ohio. The AEP Ohio Technical Requirements, which begins on page 6, is an AEP Ohio document that provides additional details. For larger or non-inverter based systems, please contact the DG Coordinator (dgcoordinator-ohio@aep.com) at (614) The following process will facilitate the safe interconnect of a customer s generation facility. The referenced documents (in italics) follow the process instructions. Process Overview 1. A completed Application for Interconnection of Inverter Based Generation Equipment 50 Kilowatts or Smaller (Short Form Application) is submitted to the Company. Included with it are: 1.) electrical one-line diagram, 2.) site diagram/sketch showing the location of the disconnect switch (see samples) and 3.) Certificate of Liability Insurance. 2. Company reviews the Short Form Application. 3. Company will notify Customer of approval/disapproval of the Short Form Application and provide any applicable conditions. 4. The Customer installs an external alternating current (ac) disconnect switch near the point of common coupling, generally within six (6) feet of the Company meter, which is readily accessible to the Company, and lockable. This disconnect switch is labeled as Generator AC Disconnect Switch. 5. The Company prepares and sends an Interconnection Agreement to the Customer. 6. The Customer signs the Interconnection Agreement and returns it to the Company. The Company will send Customer a copy of the fully executed Interconnection Agreement after the Company has signed it. 7. The Company will use a single meter that will measure the amount of energy delivered and received. 8. Following the completion of all steps above, the Customer may connect generator to the AEP Ohio distribution system. 9. Company may conduct on-site inspections to verify the proper installation and continuing safe operations of the generating facilities. 1

4 Applicability AEP Ohio MINIMUM REQUIREMENTS FOR DISTRIBUTION SYSTEM INTERCONNECTION This schedule is applicable to any customer with cogeneration, small power production facilities, and/or other on-site facilities producing electrical energy who wishes to operate such facilities in parallel with the Company s distribution system at voltages up to 35 kv. This schedule is not applicable to the interconnection and parallel operation of facilities which the Federal Energy Regulatory Commission has determined to be subject to its jurisdiction. A customer who has a facility that does not qualify for simplified interconnection pursuant to the PUCO s distribution interconnection rules (O.A.C. 4901:1-22) (Commission Rules) and the Company s technical requirements for interconnection (Technical Requirements), incorporated herein by reference, may negotiate a separate interconnection agreement with the Company and the terms and conditions of this schedule shall apply to such customers to the extent that the negotiated interconnection agreement does not conflict with this schedule. Purpose The purpose of this schedule is to implement Ohio Revised Code Section , which calls for uniform interconnection standards that are not unduly burdensome or expensive and also ensure safety and reliability, to the extent governing authority is not preempted by federal law. This schedule states the terms and conditions that govern the interconnection and parallel operation of a customer s facility with the Company s distribution system. Customer Request for Interconnection Any customer seeking to physically connect facilities to the Company's distribution system, which facilities may be used in parallel operation with the Company's distribution system, shall file an interconnection application and sign an interconnection agreement with the Company. For facilities for which the referenced Technical Requirements are applicable, the customer and Company shall execute a simplified interconnection agreement. For all other facilities, the customer and the Company shall execute an interconnection agreement which may be different from the simplified agreement, but which shall conform with the provisions of this schedule, to the extent applicable. Copies of all applicable forms and the Company s Technical Requirements are available upon request. To the extent possible, interconnection to the Company's distribution system shall take place within the following time frames: 1. Where no construction is required by the Company and the facility qualifies for simplified interconnection pursuant to the review procedure contained in the Commission Rules, interconnection shall be permitted within four weeks of the Company's receipt of a completed interconnection application in compliance with the terms and conditions of this schedule. Prior to actual interconnection, the customer must execute the interconnection agreement. 2. Where construction or system upgrades of the Company s distribution system are required, the Company shall provide the customer, in a timely fashion, an estimate of the schedule and the customer's cost for the construction or upgrades. If the customer desires to proceed with the construction or upgrades, the customer and the Company shall enter into a contract. The contract shall contain a construction schedule listing target commencement and completion dates, and an estimate of the customer s costs for construction or upgrades. Assuming the customer is ready, the interconnection shall take place no later than two weeks following the completion of such construction or upgrades. The Company shall employ best reasonable efforts to complete such system construction or upgrades in the shortest time reasonably practical. 2

5 AEP Ohio MINIMUM REQUIREMENTS FOR DISTRIBUTION SYSTEM INTERCONNECTION 3. All interconnection applications shall be processed by the Company in a nondiscriminatory manner. The Company shall promptly provide the customer a written notice of the Company s receipt of the application. The Company will endeavor to place such notice in the U.S. Mail or respond by within three business days after the application has been received by the Company s personnel designated on the application form. The Company shall provide the customer with a copy of the review procedure and a target date for processing the application. If the application is viewed as incomplete, the Company must provide a written notice within 10 days of receipt of the application by the Company s personnel designated on the application form that the application is not complete together with a description of the information needed to complete the application and a statement that processing of the application cannot begin until the information is received. The Company s target date shall permit interconnection in a timely manner pursuant to the requirements of the Commission Rules. Interconnection applications will be processed in the order that they are received. It is recognized that certain interconnection applications may require minor modifications while they are being reviewed by the Company. Such minor modifications to a pending application shall not require that it be considered incomplete and treated as a new or separate application. Minor modifications would not include at least the following: changes in facility size or location; any change requiring a new impact study; or any other substantive change. 4. If the Company determines that it cannot connect the customer s facility within the time frames required by the Commission Rules, the Company will notify the customer in writing of that fact as soon as possible. The notification will identify the reason or reasons the interconnection could not be completed within the time frames stated, and provide an estimated date for completion. This section shall not limit the rights of a customer for relief under Ohio Revised Code Chapter Technical Requirements The Company shall maintain a copy of the Technical Requirements at its business office such that the Technical Requirements are readily available to the public. The Company shall provide the Commission Staff with a copy of the Technical Requirements. Standards adopted by IEEE shall supersede the applicable provisions of the Company s Technical Requirements effective the date that IEEE adopts such standards. However, any interconnection made or initiated prior to the adoption of any national standard promulgated by IEEE shall not be subject to that standard. Regarding any IEEE minimum standard, or any guideline that the IEEE may promulgate, the Company may amend the Technical Requirements to the minimum extent required to address unique local conditions, and shall provide such amendments to the Staff and make such amendments available to customers. All Technical Requirements, including superseding standards adopted by IEEE, are incorporated herein by reference. Metering Any metering installation, testing, or recalibration required by the installation of the customer s generation facilities shall be provided consistent with the Electric Service and Safety Standards pursuant to Ohio Revised Code Chapter 4928, and specifically O.A.C. 4901: (Metering) and, as applicable, 4901: (C) (Net Metering). 3

6 AEP Ohio MINIMUM REQUIREMENTS FOR DISTRIBUTION SYSTEM INTERCONNECTION Liability Insurance Prior to interconnection with the Company, the customer must provide the Company with proof of insurance or other suitable financial instrument sufficient to meet its construction, operating and liability responsibilities pursuant to this schedule. At no time shall the Company require that the applicant negotiate any policy or renew any policy covering any liability through a particular insurance company, agent, solicitor, or broker. The Company s receipt of evidence of liability insurance does not imply an endorsement of the terms and conditions of the coverage. System Impact and Facilities Studies For those facilities that do not qualify for simplified interconnection pursuant to the review procedures included in the Commission Rules, the Company may require a supplemental review, service study, coordination study, facilities study or Company system impact study prior to interconnection. In instances where such studies are required, the scope of such studies shall be based on the characteristics of the particular generation facility to be interconnected and the Company's system at the specific proposed location. By agreement between the Company and the customer, studies related to interconnection of the generation facility may be conducted by a qualified third party. The cost of an impact facilities study performed by the Company shall be included in the costs set forth in the Interconnection Fees section of this schedule. The Company shall provide the customer with a target date for completion of any required system impact or facilities study. Any such study conducted by the Company shall be shared with the customer. Interconnection Fees The Company shall not charge any fees for interconnection other than those authorized by this schedule. Fees contained herein apply to each installation at the Company distribution voltages up to 35 kv. The Company shall charge each customer that applies for interconnection service an application fee as set forth in the Commission Rules. Fees for customer applications for interconnection that meet the qualifications for level 1, level 1.1 or level 1.2 simplified review procedures will be based on the actual costs per one-tenth of an hour of time spent by Company personnel on the simplified review. Customer applications for interconnection that meet the qualifications for level 2 expedited review will be subject to an application fee of $50, plus one dollar per kilowatt of the applicant s system nameplate capacity rating. Interconnection customers whose facilities qualify for level 3 standard review procedures shall pay an application fee of $100, plus two dollars per kilowatt of the applicant s system nameplate capacity rating. Level 2 and level 3 interconnection review processes may require that one or more interconnection studies be preformed to determine the feasibility, system impact, and cost of safely connecting the customer s generation facilities to the Company s distribution system. As specified in the Commission Rules, the cost of engineering work done as part of any feasibility, system impact or facilities study shall be billed to the customer at the Company s actual cost of performing such study. Additional Fees The customer is responsible for all equipment and installation costs of the customer s facility. The customer shall pay any additional charges, as determined by the Company, for equipment, labor, metering, testing or inspections requested by the customer. 4

7 AEP Ohio MINIMUM REQUIREMENTS FOR DISTRIBUTION SYSTEM INTERCONNECTION Construction or Upgrade Fees If the interconnection requires construction or an upgrade of the Company's system which, save for the generation facility would not be required, the Company will assess the customer the actual cost including applicable taxes of such construction or upgrade. Payment terms for such construction or upgrade will be agreed to and specified in the construction contract. The Company and the customer may negotiate for alternatives in order to reduce any costs or taxes applicable thereto. Resolution of Disputes The Company or the customer who is a non-mercantile, non-residential customer may seek resolution of any disputes which may arise out of this schedule, including the interconnection and the referenced Technical Requirements in accordance with the Commission s Rules. Special Terms and Conditions of Service This schedule is subject to the Company s Terms and Conditions of Service and all provisions of the standard service schedule under which the customer takes service. If applicable, the customer shall also take the appropriate service under the provisions of Schedule COGEN/SPP, Schedule SBS and/or Schedule NEMS. 5

8 AEP Ohio Technical Requirements for Interconnection and Parallel Operation of Distributed Generation < 50 kw APPLICABILITY These rules apply to interconnection and parallel operation of Distributed Generation (DG) equipment that is rated < 50 kw on radially operated, non-networked Company Distribution systems of 35 kv or less. 1.0 CUSTOMER DESIGN REQUIREMENTS For an interconnection to be safe to Company employees/equipment and to other customers, the following conditions are required to be met on DG equipment. 1.1 Interconnection Service Customer DG facilities must meet all applicable national, state, and local construction, operation and maintenance related safety codes, such as National Electrical Code (NEC), National Electrical Safety code (NESC), Occupational Safety and Health Administration (OSHA). 1.2 Interconnection Service Customer must provide the Company with a one-line diagram showing the configuration of the proposed DG system, including the protection and controls, disconnection devices, nameplate rating of each device, power factor rating, transformer connections, and other information deemed relevant by the Interconnection Service Customer. If the proposed DG system does not pass the screening process for simplified interconnection, additional information may be necessary from the Interconnection Service Customer and Company facilities changes may be required. 1.3 DG Equipment must be equipped with adequate protection and control to trip 1 the unit off line during abnormal 2 system conditions, according to the following requirements: Under-voltage or over-voltage within the trip time indicated below. By agreement of both the DG operator and the Company, different settings maybe used for the under voltage and over voltage trip levels or time delays. Voltage V<50% 50%<V<88% 110%<V<120% V>120% Maximum Trip Time 10 cycles 120 cycles 60 cycles 10 cycles For three phase generation, loss of balanced three-phase voltage or a single phasing condition within the trip times indicated in when voltage on at least one phase reaches the abnormal voltage levels Under-frequency or over-frequency: All DG shall follow the associated Company frequency within the range 59.3 Hz to 60.5 Hz. DG < 30 kw shall disconnect from the Company within 10 cycles if the frequency goes outside this 1 To trip is to automatically (without human intervention required) open the appropriate disconnection device to separate the DG equipment from the power system. 2 Abnormal system conditions include faults due to adverse weather conditions including but not limited to, floods, lightning, vandalism, and other acts that are not under the control of the Company. This may also result from improper design and operation of customer facilities resulting from non-compliance with accepted industry practices. 6

9 AEP Ohio Technical Requirements for Interconnection and Parallel Operation of Distributed Generation < 50 kw range. A DG > 30kW shall (1) disconnect from the Company within 10 cycles if the frequency exceeds 60.5 Hz, and (2) be capable of time delayed disconnection for frequencies in the range 59.3 Hz to 57 Hz. By agreement of both the DG operator and the Company, different settings maybe used for the under frequency and over frequency trip levels or time delays. 1.4 DG equipment requires the following additional protection to avoid damage to the Company s system during normal, as well as abnormal system conditions Synchronizing controls to insure a safe interconnection with the Company s distribution system. The DG equipment must be capable of interconnection with minimum voltage and current disturbances. Installations must meet the following synchronization parameters: voltage deviation less than + 10%, phase angle deviation less than + 10 degrees, and breaker closure time compensation A disconnect switch to isolate the DG equipment for purposes of safety during maintenance and during emergency conditions. The Company will require a disconnect device to be provided, installed by, and paid for by the Customer, which is accessible to and lockable by Company personnel, either at the primary voltage level, which may include load-break cutouts, switches and elbows, or on the secondary voltage level, which may include a secondary breaker or switch. The switch must be clearly labeled as a DG disconnect switch. 1.5 DG equipment must have adequate fault interruption and withstand capacity, and adequate continuous current and voltage rating to operate properly 3 with the Company s system. A three-phase device shall interrupt all three phases simultaneously. The tripping control of the circuit interrupting device shall be powered independently of the utility AC source in order to permit operation upon loss of the Company distribution system connection. 1.6 Harmonics and Flicker: The DG equipment shall not be a source of excessive harmonic voltage and current distortion and/or voltage flicker. Limits for harmonic distortion (including inductive telephone influence factors) will be as published in the latest issues of ANSI/IEEE 519, "Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems." Flicker occurring at the point of compliance shall remain below the Border Line of Visibility curve on the IEEE/GE curve for fluctuations less than 1 per second or greater than 10 per second. However, in the range of 1 to 10 fluctuations per second, voltage flicker shall remain below 0.4%. Refer to Exhibit 1. When there is reasonable cause for concern due to the nature of the generation and its location, the Company may require the installation of a monitoring system to permit ongoing assessment of compliance with these criteria. The monitoring system, if required, will be installed at the DG owner s expense. Situations where high harmonic voltages and/or currents originate from the distribution system are to be addressed in the Interconnection Agreement. 1.7 DC Injection from inverters shall be maintained at or below 0.5% of full rated inverter output current into the point of common coupling. 3 Properly, in this context, means within the acceptable utility or applicable industry established practices. 7

10 AEP Ohio Technical Requirements for Interconnection and Parallel Operation of Distributed Generation < 50 kw 1.8 The Distributed Generation s generated voltage shall follow, not attempt to oppose or regulate, changes in the prevailing voltage level of the Company at the point of common coupling, unless otherwise agreed to by the operators of the Distributed Generation and the Company. Distributed Generation installed on the downstream (load) side of the Company s voltage regulators shall not degrade the voltage regulation provided to the downstream customers of the Company to service voltages outside the limits of ANSI 84.1, Range A 1.9 System Grounding: The DG system should be grounded in accordance with applicable codes. The interconnection of the DG equipment with the Company s system shall be compatible with the neutral grounding method in use on the Company s system. For interconnections through a transformer to Company system primary feeders of multi-grounded, four-wire construction, or to tap lines of such systems, the maximum un-faulted phase (line-to-ground) voltages on the Company system primary feeder during single line-to-ground fault conditions with the Company system source disconnected, shall not exceed those voltages which would occur during the fault with the Company system source connected and no DG equipment System Protection: The DG owner is responsible for providing adequate protection to Company facilities for conditions arising from the operation of generation under all Company distribution system operating conditions. The owner is also responsible for providing adequate protection to their facility under any Company distribution system operating condition whether or not their DG is in operation. Conditions may include but are not limited to: 1. Loss of a single phase of supply, 2. Distribution system faults, 3. Equipment failures, 4. Abnormal voltage or frequency, 5. Lightning and switching surges, 6. Excessive harmonic voltages, 7. Excessive negative sequence voltages, 8. Separation from supply, 9. Synchronizing generation, 10. Re-synchronizing the Owner s generation after electric restoration of the supply Feeder Reclosing Coordination. In the case of a Company protection function initiating a trip of a Company protective device in reaction to a fault on the Company system, the DG unit protection and controls must be designed to coordinate with the Company protective device reclosing settings Unintentional islanding: For an unintentional island in which the DG and a portion of the Company s system remain energized through the point of common coupling, the DG shall cease to energize the Company s system within two seconds of the formation of an island The DG shall be designed to prevent the DG from being connected to a deenergized Company circuit. The customer should not reconnect DG to the Company s system after a trip from a system protection device, until the Company s system is re-energized for a minimum of five minutes. If the customer were to connect a backup generator, in the event to serve a critical load, he must open his main breaker or utilize a transfer switch prior to generator hook up, in 8

11 AEP Ohio Technical Requirements for Interconnection and Parallel Operation of Distributed Generation < 50 kw order to ensure no back feed into the Company s distribution system. This is a critical safety requirement Voltage unbalance at the point of common coupling caused by the DG equipment under any condition shall not exceed 3% (calculated by dividing the maximum deviation from average voltage by the average voltage, with the result multiplied by 100) Test results shall be supplied by the manufacturer or independent testing lab that verify, to the satisfaction of the Company, compliance with the following requirements contained in this document 4 : Over/Under Voltage Trip Settings Over/Under Frequency Trip Settings Synchronization 1.6 Harmonic Limits (tested at 25% 5 of full load rating or at a level as close to the minimum level of rated output the unit is designed to operate as practical and at a level as close to 100% of full load rating as practical) 1.7 DC Current Injection Limits (Inverters) 1.12 Anti-Islanding (Inverters) 1.13 Prevent Connection or Reconnection to De-energized System If test results are acceptable to the Company and if requested by a manufacturer, the Company will supply a letter indicating the protective and control functions for a specific DG model are approved for interconnection with the Company s distribution system, subject to the other requirements in this document. The Interconnection Service Customer must provide the Company a reasonable opportunity to witness site testing of any other protective and control functions required in this document, but not listed above. The Interconnection Service Customer must provide the Company a reasonable opportunity to perform an inspection prior to the first paralleling of the generation equipment to install and/or verify correct protective settings and connections to the system. 2.0 CUSTOMER OPERATING PROCEDURES 2.1 If high-voltage, low-voltage, or voltage flicker complaints arise from other customers due to the operation of customer DG, the customer may be required to disconnect his or her generation equipment from the Company s system until the problem has been resolved. 2.2 The operation of the DG equipment must not result in harmonic currents or voltages at the point of common coupling that will interfere with the Company s metering accuracy and/or proper operation of facilities and/or with the loads of other customers. Such adverse effects may include, but are not limited to heating of wiring and equipment, over voltage, communication interference, etc. 2.3 The Interconnection Service Customer must discontinue parallel operation when requested by the Company after reasonable prior notice except in an emergency, 4 For photovoltaic systems, a certification that the testing requirements of UL 1741 have been met may be used in place of these tests. 5 If the device is not designed to operate at this level, then the test should be at the lowest level at which it is designed to operate. 9
