83 Ill. Adm. Code 452.40
Restricted Physical Access
Section 452
Section 452.40 Restricted
Physical Access
a) Except as necessary under Section 452.50, or as required by an
order of a state or federal court or administrative agency, and in addition to
the requirements of Section 452.35(a), no merchant generation function employee
who provides generation services to Illinois customers shall be permitted
physical access to the electric utility's system control center, system
communications facilities, computer systems, information systems, data storage,
office space, file cabinets, office equipment or any other facilities,
equipment or systems used by the transmission and distribution function that
differs in any way from the access available to non-affiliated ARES. The
requirement of this subsection shall work in conjunction with Section 452.35(a)
through physical separation or secured access facilities or mechanisms.
b) Physical access by mandatory generation function employees to
the electric utility facilities, equipment or systems described in subsection
(a) that differs from the physical access provided by the electric utility to
non-affiliated ARES shall be permitted. In no event, however, shall mandatory
generation function employees circumvent, or be used or allowed by the electric
utility to circumvent, any provision of Section 452.80, 452.90, 452.100, or 452.110
of this Part. The Commission may limit or prohibit such physical access if the
Commission, taking into account Section 16-119A(c) and (d) of the Act [220 ILCS
5/16-119A(c) and (d)], determines after hearing upon complaint or on its own
motion that:
1) An electric utility has violated any provision of Section
452.80, 452.90, 452.100, or 452.110 of this Part; and
2) Such limited or prohibited physical access would better
accomplish the non-discrimination and efficient competition goals of Section 16-119A
of the Act [220 ILCS 5/16-119A].
c) Physical access by company leadership or administrative
support to the electric utility facilities, equipment or systems described in
subsection (a) shall not be restricted. In no event, however, shall company leadership
or administrative support circumvent, or be used or allowed by the utility to
circumvent, any provision of Section 452.80, 452.90, 452.100, or 452.110 of
this Part.
