Universal Citation: OH Admin Code 4901:1-22-09
Current through all regulations passed and filed through September 16, 2024
(A) Scoping meeting
(1) A scoping meeting will be
held within ten business days after the interconnection application is deemed
complete, or as otherwise mutually agreed to by the parties. The EDU and the
applicant may bring to the meeting personnel, including system engineers and
other resources as may be reasonably required to accomplish the purpose of the
meeting.
(2) The purpose of the
scoping meeting is to discuss alternative interconnection options, to determine
potential points of common coupling, to examine the applicant's proposed
generator connection, or to review an applicant's preapplication report or
existing studies relevant to the interconnection application. The parties shall
further discuss the appropriate interconnection studies required to evaluate
the interconnection of the proposed DER to the EDU's system.
(3) The scoping meeting may be waived by
mutual agreement if the parties decide to proceed directly to the
interconnection studies.
(B) Queuing
(1) When an interconnection request is
complete, the EDU shall assign the application a queue position to establish
the order in which the interconnection request will be reviewed in relation to
other interconnection requests on the same or nearby sections of the EDU's
system.
(2) The queue position of
an interconnection request shall be used to determine the cost responsibility
necessary for the construction of any facilities to accommodate the
interconnection in relation to other interconnection requests on the same or
nearby sections of the EDU's system.
(3) The EDU shall notify the applicant at the
scoping meeting about other higher-queued applicants.
(C) Interconnection study requirements
(1) One or more interconnection studies may
be required by the EDU prior to interconnection of a level 3 DER including a
feasibility study, a system impact study, and a facilities study.
(2) Each type of study required will include
an EDU interconnection tariff fee schedule approved by the commission as set
forth in rule
4901:1-22-08 of the
Administrative Code.
(3) Each type
of study will be the subject of a written study agreement between the applicant
and the EDU that includes the following:
(a) A
target date for completion of the study.
(b) A provision to share the results of the
study by the EDU with the applicant.
(c) A clear explanation of all estimated
charges.
(d) A good faith estimate
of the total number of hours needed to complete the study.
(e) An estimate of the total interconnection
study fee.
(4) A written
study agreement may include an alternative provision that allows the required
studies related to the interconnection of the DER to be conducted by a
qualified third party with the consent of the EDU.
(5) By mutual agreement of the parties, a
feasibility study, a system impact study, or a facilities study under level 3
procedures may be waived by the EDU.
(6) When the EDU determines, as a result of
the studies conducted under a level 3 review, that it is appropriate to
interconnect the DER, the EDU shall provide the applicant with a standard
interconnection agreement.
(7) If
the interconnection request is denied, the EDU shall provide a written
explanation within five business days from the denial.
An applicant has
thirty business days to cure the reasons for denial while the applicant's
position in the queue is maintained.
(D) The feasibility study
(1) No later than five business days after
the scoping meeting, the EDU shall provide the applicant with a feasibility
study agreement in accordance with the EDU's tariff to determine the
feasibility of interconnecting the applicant's proposed DER at a particular
point on the EDU's system. The feasibility study agreement shall include the
following:
(a) An outline of the scope of the
study.
(b) A non-binding good faith
estimate of the cost to perform the study.
(2) A feasibility study shall include the
following analyses for the purpose of identifying a potential adverse system
impact to the EDU's system that would result from the interconnection:
(a) Initial identification of any circuit
breaker short circuit capability limits exceeded as a result of the
interconnection.
(b) Initial
identification of any thermal overload or voltage limit violations resulting
from the interconnection.
(c)
Initial review of grounding requirements and system protection.
(d) A description and nonbinding estimated
cost of facilities required to interconnect the distributed generation facility
to the EDU's system in a safe and reliable manner.
(3) When an applicant requests that the
feasibility study evaluate multiple potential points of interconnection,
additional evaluations may be required.
(4) The applicant is
responsible for the actual cost of the EDU's additional evaluations
.
(E) The system impact study
(1) No later than five business days after
the completion of or a waiver of the feasibility study, the EDU shall provide a
distribution system impact study agreement to the applicant, using a form of
system impact study agreement in accordance with the EDU's tariff that includes
an outline of the scope of the study and a nonbinding good faith estimate of
the cost to perform the study.
(2)
If the feasibility study concludes there is no adverse system impact, or the
study identifies an adverse system impact but the EDU is able to identify a
remedy, no system impact study is necessary.
(3) A system impact study
evaluates the impact of the proposed interconnection
on the safety and reliability of the EDU's system. The purpose of the system impact study
is to:
(a) Identify and detail the system impacts
that result when a DER is interconnected without project or system
modifications.
(b) Consider the
adverse system impacts identified in the feasibility study, or potential
impacts including those identified in the scoping meeting.
(c) Consider all DERs that, on the date the
system impact study is commenced, are directly interconnected with the EDU's
system.
(d) Consider the impact of
pending higher-queued interconnection applications to the system as well as the
position of facilities having a signed interconnection agreement that are not
yet online.
(4) A system
impact study performed by the EDU shall consider the following criteria:
(a) A load flow study.
(b) A short circuit analysis.
(c) A stability analysis.
(d) Voltage drop and flicker
studies.
(e) Protection and set
point coordination studies.
(f)
Grounding reviews.
(5)
The EDU shall state the underlying assumptions of the study and show the
results of the analyses to the applicant, including the following:
(a) Any potential impediments to providing
the requested interconnection service.
(b) Any required distribution system upgrades
and a nonbinding good faith estimate of cost and time to construct the system
upgrades.
(F) The facilities study
(1) Within five business
days of completion of the system impact study, a report will be transmitted by
the EDU to the applicant with a facilities study agreement in accordance with
the EDU's interconnection tariff.
(2) If the parties agree at the scoping
meeting that no system impact study is required, the EDU shall provide to the
applicant, no later than five business days after the scoping meeting, a
facilities study agreement in accordance with the EDU's interconnection tariff
that enables the EDU to determine the interconnection facilities needed to
interconnect the applicant's proposed DER at a particular point on the EDU's
system.
(3) The facilities study
agreement shall include both of the following:
(a) An outline of the scope of the
study.
(b) A nonbinding good faith
estimate of the cost to perform the facilities study to cover the cost of the
