Iowa Admin. Code r. 199-45.5 - General requirements
(1) When
an interconnection request for a distributed generation facility includes
multiple energy production devices at a site for which the applicant seeks a
single point of interconnection, the interconnection request shall be evaluated
on the basis of the aggregate nameplate capacity of the multiple
devices.
(2) When an
interconnection request is for an increase in capacity for an existing
distributed generation facility, the interconnection request shall be evaluated
on the basis of the new total nameplate capacity of the distributed generation
facility.
(3) The utility shall
designate a point of contact and provide contact information on the utility's
website. The point of contact shall be able to direct applicant questions
concerning interconnection request submissions and the interconnection request
process to knowledgeable individuals within the utility.
(4) The information that the utility makes
available to potential applicants can include previously existing utility
studies that help applicants understand whether it is feasible to interconnect
a distributed generation facility at a particular point on the utility's
electric distribution system. However, the utility can refuse to provide the
information to the extent that providing it violates security requirements or
confidentiality agreements, or is contrary to state or federal law. In
appropriate circumstances, the utility may require a confidentiality agreement
prior to release of this information.
(5) When an interconnection request is deemed
complete by the utility, any modification that is not agreed to by the utility
requires submission of a new interconnection request.
(6) The applicant shall provide, upon utility
request, proof of the applicant's legal right to control the site(s). Site
control may be demonstrated through:
a.
Ownership of, a leasehold interest in, or a right to develop a site for the
purpose of constructing, the distributed generation facility;
b. An option to purchase or acquire a
leasehold site for such purpose; or
c. Exclusivity or other business relationship
between the interconnection customer and the entity having the right to sell,
lease, or grant the interconnection customer the right to possess or occupy a
site for such purpose.
(7) To minimize the cost to interconnect
multiple distributed generation facilities, the utility or the applicant may
propose a single point of interconnection for multiple distributed generation
facilities located at an interconnection customer site that is on contiguous
property. If the applicant rejects the utility's proposal for a single point of
interconnection, the applicant shall pay any additional cost to provide a
separate point of interconnection for each distributed generation facility. If
the utility, without written technical explanation, rejects the customer's
proposal for a single point of interconnection, the utility shall pay any
additional cost to provide separate points of interconnection for each
distributed generation facility.
(8) Any metering required for a distributed
generation interconnection shall be installed, operated, and maintained in
accordance with the utility's metering rules and inspection and testing
practices defined in 199-Chapter 20. Any such metering requirements shall be
identified in the Level 1 Interconnection Request Application form and
Distributed Generation Interconnection Agreement or the Levels 2 to 4
Distributed Generation Interconnection Request Agreement executed between the
interconnection customer and the utility.
(9) Utility requirements for monitoring and
control of distributed generation facilities are permitted only when the
nameplate capacity rating is greater than 1 MVA. Monitoring and control
requirements shall be reasonable, consistent with the utility's published
requirements, and shall be clearly identified in the interconnection agreement
between the interconnection customer and the utility. Transfer trip shall not
be considered utility monitoring and control when required and installed to
protect the electric distribution system or an affected system against adverse
system impacts.
(10) The utility
may require a witness test after the distributed generation facility is
constructed. The applicant shall provide the utility with at least 15 business
days' notice of the planned commissioning test for the distributed generation
facility. The applicant and utility shall schedule the witness test at a
mutually agreeable time. If the witness test results are not acceptable to the
utility, the applicant shall be granted 30 business days to address and resolve
any deficiencies. The time period for addressing and resolving any deficiencies
may be extended upon the mutual agreement of the utility and the applicant
prior to the end of the 30 business days. An initial request for extension
shall not be denied by the utility; subsequent requests may be denied. If the
applicant fails to address and resolve the deficiencies to the utility's
satisfaction, the interconnection request shall be deemed withdrawn. Even if
the utility or an entity approved by the utility does not witness a
commissioning test, the applicant remains obligated to satisfy the
interconnection test specifications and requirements set forth in IEEE Standard
1547, Section 11. The applicant shall, if requested by the utility, provide a
copy of all documentation in its possession regarding testing conducted
pursuant to IEEE Standard 1547.1.
