2015 - 2016 LEGISLATURE
ASSEMBLY SUBSTITUTE AMENDMENT 1,
TO ASSEMBLY BILL 560
January 15, 2016 - Offered by Representative Kahl.
1An Act to renumber and amend
196.496 (1); and to create
196.496 (1) (a), 2
196.496 (1) (c) and 196.496 (3) of the statutes; relating to: disconnection
3requirements for distributed generation facilities.
Analysis by the Legislative Reference Bureau
This substitute amendment imposes requirements on the connection of
distributed generation facilities (DGFs) to utility distribution systems by customers
of electric public utilities. Under current law, the Public Service Commission must
promulgate rules regarding the connection of DGFs to utility distribution systems
and defines a DGF for that purpose as a facility with a capacity of no more than 15
megawatts that is located either 1) at or near the point where the electricity will be
used or 2) in a location that will support the functioning of the electric power
distribution grid. The substitute amendment uses the same definition of DGF.
The substitute amendment prohibits a customer from installing a DGF that is
connected to the distribution system of an electric public utility unless the customer
satisfies certain requirements. The requirements apply to installations made on or
after the substitute amendment's effective date, and include the following: 1) the
customer must install protection devices for each DGF that satisfy specified
requirements, and 2) the customer must include equipment circuit breakers that
satisfy specified requirements. Also, the substitute amendment allows the electric
public utility to require the customer install interconnection disconnect switches for
DGFs that satisfy specified requirements. If so required, the customer must follow
the electric public utility's recommended switching, clearance, tagging, and locking
procedures; label the switches as required under the substitute amendment; and
post the customer's disconnection procedure next to the switches.
For DGFs that customers installed and connected to utility distribution
systems before the substitute amendment's effective date, the substitute
amendment requires the customer to attach a permanent placard to the the
customer's meter that identifies the location of the devices for disconnecting the DGF
from the distribution system. Also, the customer must notify the electric public
utility of the location of the DGF and the disconnection devices. The substitute
amendment requires the customer to make the attachment and notification within
approximately six months after the substitute amendment's effective date.
The people of the state of Wisconsin, represented in senate and assembly, do
enact as follows:
196.496 (1) of the statutes is renumbered 196.496 (1) (intro.) and 2
amended to read:
196.496 (1) Definition
(intro.) In this section, "distributed:
generation facility" means a facility for the generation of 5
electricity with a capacity of no more than 15 megawatts that is located near the point 6
where the electricity will be used or is in a location that will support the functioning 7
of the electric power distribution grid.
196.496 (1) (a) of the statutes is created to read:
(a) "Customer" means a customer of an electric public utility.
196.496 (1) (c) of the statutes is created to read:
(c) "Electric public utility" means a public utility that owns or 12
operates an electric distribution system.
196.496 (3) of the statutes is created to read:
196.496 (3) Disconnection.
(a) On or after the effective date of this paragraph 15
.... [LRB inserts date], no customer may install a distributed generation facility that
is connected to the distribution system of an electric public utility unless the 2
customer does all of the following:
1. Installs protection devices for each connected distributed generation facility 4
that satisfy all of the following:
a. The devices ensure that the current supplied by the distributed generation 6
facility is interrupted if a fault or other potentially dangerous event occurs on the 7
b. If a fault or event described in subd. 1. a. occurs and the distribution system 9
is deenergized, the devices ensure that any distributed generation facility that is 10
connected to the system automatically disconnects.
c. The devices prevent electrically closing a distributed generation facility that 12
is out of synchronization with the distribution system.
2. Includes in the installation equipment circuit breakers on the distributed 14
generation facility side of the point where the distributed generation facility is 15
electrically connected to the customer's electrical system. The equipment circuit 16
breakers shall be capable of interrupting the maximum available fault current and 17
shall meet all applicable standards of Underwriters Laboratories Inc., the American 18
National Standards Institute, and the Institute of Electrical and Electronics 19
3. If required by the electric public utility, furnishes and installs an 21
interconnection disconnect switch that satisfies all of the following:
a. The switch opens, with a visual break, all ungrounded poles of the 23
b. The switch is rated for the voltage and fault current requirements of the 25
distributed generation facility.
c. The switch meets all applicable standards of Underwriters Laboratories Inc., 2
the American National Standards Institute, and the Institute of Electrical and 3
d. The switch enclosure is properly grounded.
e. The switch is accessible at all times, is located for ease of access to electric 6
public utility personnel, and is capable of being locked in the open position.
4. In making an installation required under subd. 3., does all of the following:
a. Follows the electric public utility's recommended switching, clearance, 9
tagging, and locking procedures.
b. Labels the interconnection disconnect switch, "Interconnection Disconnect 11
Switch," by means of a permanently attached sign with clearly visible and 12
c. Provides and posts the customer's procedure for disconnecting the 14
distributed generation facility that is next to the interconnection disconnect switch.
(b) No later than the first day of the 7th month beginning after the effective date 16
of this paragraph .... [LRB inserts date], a customer who has installed a distributed 17
generation facility that is connected to the electric distribution system of an electric 18
public utility before the effective date of this paragraph .... [LRB inserts date], shall 19
do the following:
1. Attach a permanent placard to the customer's electric meter that identifies 21
the location of the devices for disconnecting the distributed generation facility from 22
the electric distribution system.
2. Notify the electric public utility of the location of the distributed generation 24
facility and the devices described in subd. 1.
