4901:1-22-07 Expedited procedures.

Level 2 expedited review process

(A) The electric distribution utility (EDU) shall review an applicant's completed interconnection service application that meets the criteria set forth in paragraph (B) of this rule on an expedited basis.

(B) In order for the application to be approved by the EDU under the level 2 expedited review procedure, the applicant's proposed certified inverter-based or synchronous distributed generation facility in aggregation with all other generators on the EDU's circuit must be two megawatts or less and the results of interconnecting the applicant's generating facility to the EDU's distribution system must comply with the following parameters:

(1) The proposed distributed generation facility's point of interconnection shall not be on a transmission line

(2) The interconnection is to a radial distribution circuit.

(3) The proposed distributed generation facility complies with institute of electrical and electronics engineers (IEEE) 1547 standard and underwriters uaboratory 1741 standard, effective as set forth in rule 4901:1-22-03 of the Administrative Code.

(4) The proposed distributed generation facility, in aggregation with other generation interconnected to the distribution side of a substation transformer feeding the circuit where the distributed generation facility proposes to interconnect, shall not exceed two megawatts in an area where there are known or posted transient stability limitations to generating units located in the general electrical vicinity (for example, three or four distribution busses from the point of interconnection).

(5) The proposed distributed generation's capacity in aggregation with other generation on the circuit shall not exceed fifteen per cent of the total circuit peak load as most recently measured at the substation; nor will it exceed fifteen per cent of a distribution circuit line section annual peak load.

(6) The proposed distributed generation facility, in aggregation with other generation on the distribution circuit, shall not contribute more than ten per cent to the distribution circuit's maximum fault current at the point on the primary voltage distribution line nearest the point of common coupling.

(7) The proposed distributed generation facility, in aggregation with other generation on the distribution circuit, may not cause any distribution protective devices and equipment (including substation breakers, fuse cutouts, and line reclosers), or other customer equipment on the electric distribution system to be exposed to fault currents exceeding eighty-five per cent of the short circuit interrupting capability.

(8) The applicant shall not request interconnection on a circuit that already exceeds eighty-five per cent of the short circuit interrupting capability.

(9) When a proposed distributed generation facility is single phase and is to be interconnected on a center tap neutral of a two hundred forty volt service, its addition shall not create an imbalance between the two sides of the two hundred forty volt service of more than twenty per cent of the nameplate rating of the service transformer.

(10) The proposed distributed generation facility installation is certified to pass an applicable non-islanding test, or uses reverse power relays or other means to meet IEEE 1547 standard unintentional islanding requirements, effective as set forth in rule 4901:1-22-03 of the Administrative Code.

(11) On a three-phase, three-wire primary electric distribution line, a three- or single-phase generator shall be connected phase-to-phase.

(12) When the applicant's facility is to be connected to three-phase, four-wire primary EDU distribution lines, a three- or single-phase generator will be connected line-to-neutral and will be effectively grounded.

(13) A review of the type of electrical service provided to the applicant, including line configuration and the transformer connection, will be conducted to limit the potential for creating over voltages on the EDU's electric distribution system due to a loss of ground during the operating time of any anti-islanding function.

(14) When the proposed distributed generation facility is to be interconnected on single-phase shared secondary line, the aggregate generation capacity on the shared secondary line, including the proposed distributed generation facility, will not exceed ten kilowatts.

(15) Construction of facilities by the EDU on its own system is not required to accommodate the distributed generation facility.

(C) The EDU's tariff for level 2 expedited review processing fees will include the following:.

(1) An application fee of up to fifty dollars, plus one dollar per kilowatt of the applicants' system nameplate capacity rating.

(2) The cost of engineering work done as part of any impact or facilities study, billed at actual costs incurred.

(3) The actual cost of any minor modification of the electric distribution utility's system that would otherwise not be done but for the applicant's interconnection request

(D) When an EDU determines that the application passes the level 2 review process, or fails one or more of the level 2 criteria set forth in paragraph (B) of this rule but the EDU determines that the distributed generation facility can be interconnected safely and reliably, the EDU shall provide the applicant with a standard distributed generation interconnection agreement within five business days after such determination. The standard interconnection agreement shall be consistent with the uniform requirements for an interconnection agreement enumerated in rule 4901:1-22-10 of the Administrative Code and include a timetable for the physical interconnection of the applicant's proposed distributed generation facility to the EDU's system.

(E) When additional review by the EDU may be appropriate for an application failing to meet one or more of the level 2 criteria, the EDU shall offer to do the following for the applicant:

(1) Perform additional review to determine whether minor modifications to the electric distribution system would enable the interconnection to be made consistent with safety, reliability and power quality criteria.

(2) Provide the applicant with a nonbinding, good faith estimate of the EDU's costs of additional review and minor modifications.

(3) Notify the applicant that the additional review or modifications will be undertaken only after the applicant consents in writing to pay for the review and modifications.

(F) Within five days after completion of the level 2 expedited procedure leading to the EDU's approval for interconnection of the applicant's proposed distributed generation facility installation and collection by the EDU of the applicant's payment pursuant to paragraph (E)(3) of this rule, the EDU shall provide the applicant with a standard interconnection agreement. The standard interconnection agreement shall be consistent with the uniform requirements for an interconnection agreement enumerated in rule 4901:1-22-10 of the Administrative Code and include a mutually agreed upon timetable for the physical interconnection of the applicant's proposed distributed generation facility to the EDU's system.
