- Section 54-15-106
- Section 54-12-2
Anticipated cost or savings to:
the state budget:
None are anticipated relative to the day-to-day operations of a state agency. To the extent a state agency may desire to install an electrical generating facility and interconnect with a public utility, this rule clarifies costs and procedural requirements. It is not anticipated that this rule will alter or change costs associated with interconnection as it follows general practices currently followed for installation of equipment and procedures used by entities operating in this state, in neighboring states or follows federal agency terms applicable to interconnection of customer-owned generating facilities with public utilities.
local governments:
None are anticipated relative to the day-to-day operations of local governments. To the extent a local governmental entity may desire to install an electrical generating facility and interconnect with a public utility, this rule clarifies costs and procedural requirements. It is not anticipated that this rule will alter or change costs associated with interconnection as it follows general practices currently followed for installation of equipment and procedures used by entities operating in this state, in neighboring states or follows federal agency terms applicable to interconnection of customer-owned generating facilities with public utilities.
small businesses:
None are anticipated relative to the day-to-day operations of other entities. To the extent a small business customer may desire to install an electrical generating facility and interconnect with a public utility, this rule clarifies costs and procedural requirements. It is not anticipated that this rule will alter or change costs associated with interconnection as it follows general practices currently followed for installation of equipment and procedures used by entities operating in this state, in neighboring states or follows federal agency terms applicable to interconnection of customer-owned generating facilities with public utilities.
persons other than small businesses, businesses, or local governmental entities:
None are anticipated relative to the day-to-day operations of small businesses. To the extent a customer may desire to install an electrical generating facility and interconnect with a public utility, this rule clarifies costs and procedural requirements. It is not anticipated that this rule will alter or change costs associated with interconnection as it follows general practices currently followed for installation of equipment and procedures used by entities operating in this state, in neighboring states or follows federal agency terms applicable to interconnection of customer-owned generating facilities with public utilities.
Compliance costs for affected persons:
See "Persons other than small businesses, etc." above. This rule generally mirrors the interconnection requirements set by the U.S. Federal Energy Regulatory Commission for utilities under its jurisdiction and which are generally followed by investor-owned utilities. Reporting requirements are minor and records required are similar to those which would be captured by a prudent public utility or may be required for compliance with a renewable energy portfolio standard imposed by state law. Specific portions of the rule may be waived for good cause. Required studies reflect those already necessary to ensure a safe, reliable interconnection. It is anticipated that compliance costs are similar to costs already incurred to do the same functions and activities already done to interconnect the generating resources which are the subject of the proposed rule.
Comments by the department head on the fiscal impact the rule may have on businesses:
Utah law encourages the development of alternative and independent electric generation resources. The proposed rule establishes greater uniformity in the process and the means through which electricity generating resources, not owned by a public utility, may be connected with a public utility's electricity distribution system. It follows existing practices of affected utilities, the requirements of federal regulatory interconnection terms, or processes and procedures reasonably expected for safe and efficient interconnection of the size of resources subject to the proposed rule. As it provides for greater consistency on the terms and conditions for interconnection, it is expected to reduce transactions costs associated with interconnecting these types of facilities and represents a reasonable balancing of the interests of those individuals who wish to interconnect their facilities and public utilities with whom interconnection is sought. The changes made to the proposed rule are to clarify the original proposed rule in light of the comments made to the proposed rule.

(ii) The disconnect switch may be located
more than 10 feet from the public utility meter if permanent
instructions are posted in letters of appropriate size at the meter
indicating the precise location of the disconnect switch. In this
case the public utility must approve in writing the location of the
disconnect switch prior to the installation of the generating
facility. For those instances where the interconnection customer
and the public utility cannot agree to the implementation of this
section, the public utility or interconnection customer may refer
the matter to the [C]commission according to the designated dispute
resolution process.
(iii) Nothing in this exemption precludes an interconnection customer or a public utility from voluntarily installing a manual disconnect switch.
(3) In the event that no disconnect switch is installed, the interconnection customer's electric service may be disconnected by the public utility entirely if the generating facility must be physically disconnected from the public utility's distribution system as specified in Subsection R746-312-4(5).
(4) For those public utilities whose governing authority, pursuant to Section 54-15-106, after appropriate notice an opportunity for public comment, elects to adopt by rule additional reasonable interconnection safety, power quality and interconnection requirements for net metering generating facilities and who determines that a disconnect switch for net metering generating facilities less than 10 kilowatts is necessary, those public utilities must:
(a) address the usage of the disconnect switch in the public utility's operations training requirements and standard operating procedures, including, among other things, how the disconnect switches will be managed, including tracking of switches, the procedures under which the disconnect switch must be used during normal operations, construction projects, trouble situations, and during restoration of service activities, and training on operation and usage of the disconnect switch;
(b) file a copy of the disconnect switch procedures, and any updates, along with the governing authority's documentation of appropriate notice and opportunity for public comment with the commission; and
(c) document in writing each time the public utility has utilized each specific disconnect switch and the reason for its usage and make this information available to the commission upon request.
(5) The public utility may operate the manual disconnect switch or disconnect the customer generating facility pursuant to the conditions set forth below, thereby isolating the customer generating system, without prior notice to the customer. To the extent practicable, however, prior notice shall be given. If prior notice is not given, the utility shall at the time of disconnection leave a door hanger or other such notice notifying the customer that their customer generating system has been disconnected, including an explanation of the condition necessitating such action. The public utility shall reconnect the customer generating system as soon as reasonably practicable after the condition necessitating disconnection is remedied.
(a) Any of the following conditions shall be cause for the public utility to manually disconnect a generating facility from its system:
(i) Emergencies or maintenance requirements on the public utility's distribution system;
(ii) Hazardous conditions existing on the public utility's distribution system which may affect safety of the general public or public utility employees due to the operation of the customer generating facility or protective equipment as determined by the public utility; or
(iii) Adverse electrical effects (Such as high or low voltage, unacceptable harmonic levels, or RFI interference) on the electrical equipment of the public utility's other electric consumers caused by the customer generating facility as determined by the public utility.
(6) Subsequent to becoming interconnected to a public utility the interconnection customer must notify the public utility of all proposed modifications to the generating facility or equipment package which will increase the generation capacity of a customer generation facility.
(a) Notification must be provided in the form of a new application submitted in accordance with the level of review required by this rule; and
(b) The application must specify the proposed modification(s).
(7) Aggregating Multiple Generators: If the interconnection request is for a generating facility which includes multiple generating facilities at a site for which the interconnection customer seeks a single point of interconnection, the interconnection request must be evaluated for the purposes of the interconnection on the basis of the aggregate electric nameplate capacity of the generating facilities.
R746-312-5. [Interconnection Facility ]Certifications.
(1) To qualify for the Level 1 and the Level 2 interconnection review procedures set forth below, a generating facility must be certified as complying with the following standards, as applicable:
(a) IEEE standards; and
(b) UL 1741 Inverters, Converters, and Controllers for Use in Independent Power Systems (January 2001).
(2) An equipment package will be considered certified for interconnected operation if it has been submitted by a manufacturer to a nationally recognized testing and certification laboratory, and has been tested and listed by the laboratory for continuous interactive operation with an electric distribution system in compliance with relevant codes and standards.
(3) If the equipment package has been tested and listed in accordance with this section as an integrated package, which includes a generator or other electric source, the equipment package will be deemed certified, and the public utility may not require further design review, testing or additional equipment.
(4) If the equipment package includes only the interface components (switchgear, inverters, or other interface devices), an interconnection customer must show that the generator or other electric source being utilized with the equipment package is compatible with the equipment package and consistent with the testing and listing specified for the package. If the generator or electric source being utilized with the equipment package is consistent with the testing and listing performed by the nationally recognized testing and certification laboratory, the equipment package will be deemed certified, and the public utility may not require further design review, testing or additional equipment.
