technologies that increase the capacity, efficiency, reliability, or
safety of an existing or new electric transmission facility, including:
(1) grid enhancing technologies, such as dynamic line rating,
advanced power flow controllers, and topology optimization;
(2) advanced conductors; and
(3) other technologies designed to:
(A) reduce transmission congestion; or
(B) increase the capacity, efficiency, reliability, or safety of
an existing or new electric transmission facility.
(b) As used in this section, "electric utility" refers to an electric
utility that:
(1) is listed in 170 IAC 4-7-2(a); and
(2) owns and operates a transmission or distribution system.
(c) In any integrated resource plan filed with the commission
under 170 IAC 4-7 after December 31, 2025, an electric utility must
include a description of the potential use of, or investment in, one
(1) or more advanced transmission technologies to enable the
electric utility to safely, reliably, efficiently, and cost effectively

meet electric system demand, taking into consideration cost, risk,
uncertainty, and the alternative investments needed to build new
transmission infrastructure if advanced transmission technologies
are not deployed.
(d) In any integrated resource plan filed with the commission
under 170 IAC 4-7 after December 31, 2029, an electric utility must
include a description of the electric utility's transmission and
distribution systems, as applicable, as specified by the commission
under 170 IAC 4-7.
SECTION 2. IC 8-1-8.5-14 IS ADDED TO THE INDIANA CODE
AS A NEW SECTION TO READ AS FOLLOWS [EFFECTIVE JULY
1, 2025]: Sec. 14. (a) As used in this section, "advanced
transmission technologies" means software or hardware
technologies that increase the capacity, efficiency, reliability, or
safety of an existing or new electric transmission facility, including:
(1) grid enhancing technologies, such as dynamic line rating,
advanced power flow controllers, and topology optimization;
(2) advanced conductors; and
(3) other technologies designed to:
(A) reduce transmission congestion; or
(B) increase the capacity, efficiency, reliability, or safety of
an existing or new electric transmission facility.
(b) As used in this section, "public utility" has the meaning set
forth in section 1 of this chapter.
(c) The commission shall conduct a study to evaluate the
potential use or deployment of advanced transmission technologies
by public utilities to enable public utilities to:
(1) safely, reliably, efficiently, and cost effectively meet
electric system demand; and
(2) provide safe, reliable, and affordable electric utility service
to customers.
(d) In conducting the study, the commission shall evaluate the
following:
(1) The attributes, functions, costs, and benefits of various
advanced transmission technologies, including grid enhancing
technologies and advanced conductors. In evaluating the
attributes of various advanced transmission technologies
under this subdivision, the commission shall consider whether
a particular technology does the following:
(A) Increases transmission capacity.
(B) Increases transmission efficiency.
(C) Reduces transmission congestion.

(D) Reduces the curtailment of generation resources.
(E) Increases system reliability.
(F) Increases system resiliency.
(G) Increases the capacity to connect new energy
generation resources.
(2) The potential of each of the advanced transmission
technologies studied to be used or deployed by public utilities
to provide safe, reliable, and affordable electric utility service
to customers in Indiana, considering existing and planned
transmission infrastructure and projected demand growth.
(3) Potential reductions in project costs and project
completion timelines by deploying advanced transmission
technologies, as compared to traditional transmission
infrastructure.
(4) Potential ways to streamline the deployment of advanced
transmission technologies, including streamlined processes for
permitting, maintenance, and upgrades.
(5) Any other aspect of advanced transmission technologies
that the commission determines will assist policymakers,
public utilities, ratepayers, and other stakeholders in
understanding the potential role of advanced transmission
technologies in the transmission system serving Indiana and
the region.
(e) In conducting the study required by this section, the
commission may consult with or invite comments from:
(1) regional transmission organizations;
(2) the Federal Energy Regulatory Commission or other
federal regulators;
(3) public utilities;
(4) the office of the utility consumer counselor;
(5) associations or organizations representing utility
ratepayers;
(6) regulatory commissions in other states;
(7) engineers or other experts; or
(8) other stakeholders.
The commission may incorporate any information or comments
received under this subsection in its report under subsection (f).
(f) The commission shall include in the annual report that the
commission is required to submit under IC 8-1-1-14 before
