(a) Generator or inverter.
(b) Point of interconnection.
(c) Point of common coupling.
(d) Lockable interconnection disconnect switch.
(e) Method of grounding, including generator and transformer ground connections.
(f) Protection functions and systems.
(2) The applicant shall provide technical specifications of the point of interconnection, including all anti-islanding and power quality protective systems. The specifications regarding the anti-islanding protective systems shall describe all automatic features provided to disconnect the DG facility from the distribution system in case of loss of grid power, including the functions for over/under voltage, over/under frequency, overcurrent, and loss of synchronism. The applicant shall also provide technical specifications for the generator, lockable interconnection disconnect switch, and grounding and shall attach the technical specification sheets for any certified equipment. The applicant shall include, with the one-line schematic, a statement by the manufacturer that its equipment meets or exceeds the type tested requirements for certification in these guidelines.
PSC 119.0314 Control schematics. As part of the application, the applicant shall provide a complete set of control schematics, when non-certified equipment is proposed, showing all protective functions and controls for generator protection and distribution system protection.
PSC 119.0315 Site plan. For all categories, the applicant shall provide a site plan that shows the location of the interconnection disconnect switch, adjoining street name, and the street address of the DG facility. For Category 2, 3, or 4 DG facilities, the site plan shall show the location of major equipment, electric service entrance, electric meter, interconnection disconnect switch, and interface equipment.
PSC 119.0316 Transformers. The public utility may require a DG facility to be isolated from other customers by installation of a separate power transformer. When a separate transformer is required, the utility may include its actual cost in the distribution system upgrade costs. The applicant is responsible for supplying and paying for any custom transformer. This requirement may not be required for an induction-type generator with a capacity of 5 kW or less, or for other generating units of 10 kW or less that utilize a line-commutated inverter.
PSC 119.0317 Secondary or spot networks. The owner of a DG facility designed to operate in parallel with a spot or secondary network service shall provide relaying or control equipment that is rated and listed for the application and is acceptable to the public utility.
PSC 119.0318 Telemetry. For a Category 3 DG facility, the public utility may require that the facility owner provide telemetry equipment whose monitoring functions include transfer-trip functionality, voltage, current, real power (watts), reactive power (vars), and breaker status. The public utility may waive this requirement. The owner of a Category 4 DG facility shall provide telemetry equipment with transfer-trip functionality in addition to readout of voltage, current, real power (watts), reactive power (vars), and breaker status.
Subchapter IV-- Equipment Certification
PSC 119.0401 Certified paralleling equipment. DG paralleling equipment that a nationally recognized testing laboratory certifies as meeting the applicable type testing requirements of UL 1741 (January 17, 2001 revision) is acceptable for interconnection, without additional protection systems, to the distribution system. The applicant may use certified paralleling equipment for interconnection to a distribution system without further review or testing of the equipment design by the public utility, but the use of this paralleling equipment does not automatically qualify the applicant to be interconnected to the distribution system at any point in the distribution system. The public utility may still require an engineering review to determine the compatibility of the distributed generation system with the distribution system capabilities at the selected point of common coupling.
PSC 119.0402 Non-certified paralleling equipment. (1) Any DG facility that is not certified under s.
PSC 119.0401 shall be equipped with protective hardware or software to prevent islanding and to maintain power quality. The applicant shall provide the final design of this protective equipment. The public utility may review and approve the design, types of protective functions, and the implementation of the installation. The applicant shall own the protective equipment installed at its facility.
(2) The applicant shall calibrate any protective system approved under sub. (1) to the specifications of the public utility. The applicant shall obtain prior written approval from the public utility for any revisions to specified protection system calibrations.
Subchapter V -- Testing of DG Facility Installations
PSC 119.0501 Anti-islanding test. The public utility may perform an anti-islanding test or observe the automatic shutdown before giving final written approval for interconnection of the DG facility. The anti-islanding test requires that the DG facility shut down upon sensing the loss of power on the distribution system. Output voltage shall reduce to zero within two seconds of separation from the distribution system.
PSC 119.0502 Commissioning tests for paralleling equipment in Categories 2 to 4. The public utility shall provide the acceptable range of settings for the paralleling equipment of a Category 2, 3, or 4 DG facility. The applicant shall program protective equipment settings into this paralleling equipment. The public utility may verify the protective equipment settings prior to allowing the DG facility to interconnect to the distribution system.
PSC 119.0503 Additional tests. The public utility or applicant may, upon reasonable notice, re-test the DG facility installation. The party requesting additional testing shall bear the cost of these tests.
Initial Regulatory Flexibility Analysis
The proposed rules would apply to electric public utilities. The proposed rules do not affect small businesses as defined in s.
227.114.
Fiscal Estimate
These rules establish uniform statewide standards for interconnection of Distributed Generation facilities to an Electric distribution system. The rules are being created at the direction of Legislation in Wis. Act 16. These rules govern the relationship between a distributed generation facility and a utility and as such, do not have a fiscal impact on either state or local government.

General Summary of Proposed Rule
This rule making will amend ch.
Trans 403, relating to the Scholarship and Loan Repayment Incentive Grant Program, to conform to the statutory changes of s.
85.107, amended by
2001 Wis. Act 16 (the 2001-03 biennial budget act). The changes will allow the Department to recruit and select from an expanded class of targeted group members for program inclusion under any job classification, not just the Civil Engineering classification.
Section
85.107, Stats., relating to the Scholarship and Loan Payment Incentive Grant Program, allows for the assistance in improving the representation of targeted group members within job classifications in which targeted group members are underutilized in the Department.
Ch.
Trans 403 currently exists to allow minorities to participate in the Loan Repayment Incentive Grant Program as civil engineers. Expanding the class of recipients and the job classifications consistent with recent changes to s.
85.107, Stats., will allow the Department to expand the recruitment search for program inclusion to place targeted group members in any underutilized position in the Department.
This proposed rule also eliminates some administrative requirements regarding the timing of program applications and payments, and of program management within the Department.
Fiscal Impact
The Department estimates that there will be no fiscal impact on the liabilities or revenues of any county, city, village, town, school district, vocational, technical and adult education district, sewerage district, or federally-recognized tribes or bands. The Department estimates that there will be no fiscal impact on state revenues or liabilities.
Initial Regulatory Flexibility Analysis
This proposed rule will have no adverse impact on small businesses.
