SECTION 1. SHORT TITLE. 
This Act may be cited as the ‘‘Integrated Resource 
Planning Modernization Act’’. 
SEC. 2. DEVELOPMENT OF GUIDELINES AND BEST PRAC-
TICES FOR ELECTRIC UTILITY INTEGRATED 
RESOURCE PLANNING. 
(a) IN GENERAL.—The Secretary, in consultation 
with State public utility commissions, State energy offices, 
owners or operators of electric utilities (including investor- 
owned utilities, municipal utilities, and electric coopera-
tives), balancing area authorities, Transmission Organiza-
tions, and other relevant stakeholders, shall develop guide-
lines and best practices for integrated resource planning 
of the electricity system. 
(b) REQUIREMENTS.— 
(1) KEY
ISSUES.—The guidelines and best 
practices developed under subsection (a) shall ad-
dress key issues related to integrated resource plan-
ning. In developing the guidelines and best practices, 
the Secretary shall consider, at a minimum, the fol-
lowing issues, while retaining discretion to incor-
porate additional considerations and to refine the 
scope, level of detail, and implementation approaches 
for each issue as appropriate:

eling and resource adequacy analysis in an

iterative manner to improve integrated resource 
planning by ensuring the expanded electricity 
system achieves resource adequacy while mini-
mizing costs. 
(B) The consideration of a wide range of 
alternatives for capacity expansion models to 
meet resource adequacy targets, including the 
traditional expansion of electricity generation 
and transmission capacity and the use of novel 
grid-enhancing technologies, small and large- 
scale storage, distributed energy resources, be-
hind-the-meter interventions, and demand-side 
interventions. 
(C) Explicit consideration of electric trans-
mission in capacity expansion modeling and its 
contribution to resource adequacy and reli-
ability of electricity systems. 
(D) The use of an interregional planning 
approach in capacity expansion modeling to 
evaluate the resource adequacy benefits of ca-
pacity resource sharing across regions, includ-
ing through collaboration between States, bal-
ancing area authorities, electric utilities, Trans-
mission Organizations, and other relevant 
stakeholders.

(E) The integration of technical, financial, 
and regulatory information from other fuel sup-
ply systems, such as the natural gas network. 
(F) The use of scenario analysis developed 
using capacity expansion modeling and trans-
mission expansion modeling to represent a full 
range of future characteristics of the electricity 
system, including the availability of different 
electricity generating and storage resources, 
and transmission infrastructure. 
(G) The use of probabilistic models in re-
source adequacy analysis to account for varia-
bility and uncertainty in the supply and de-
mand of electricity, including the impact of ex-
treme weather event scenarios, forecasting er-
rors, fuel prices, and other uncertainties on 
such supply and demand. 
(H) The use of historical weather data and 
forward-looking meteorological projections, in-
cluding with respect to extreme weather event 
scenarios, to account for the variability in elec-
tricity demand, electricity generation from indi-
vidual or groups of electricity generators, and 
electricity system outages to assess resource 
adequacy.

(I) The use of multiple resource adequacy 
metrics for assessing resource adequacy to ac-
count for the magnitudes, frequencies, and du-
rations of potential events that stress the elec-
tricity system. 
(J) The use of scorecards that summarize 
the costs and a wide range of benefits of sce-
narios developed through the integrated re-
source planning process, including— 
(i) costs of infrastructure investments; 
(ii) environmental sustainability; 
(iii) resource adequacy and reliability; 
(iv) economic impacts; and 
(v) other costs and benefits that are 
relevant to the decision-making objectives 
of States, electric utilities, balancing area 
authorities, Transmission Organizations, 
and other relevant stakeholders. 
(K) The use of rigorous mechanisms for 
capacity accreditation to measure the capacity 
value of possible investments that support re-
source adequacy, including— 
(i) capacity values for both conven-
tional and emerging generation resources,

interventions; and 
(iii) capacity values for transmission 
infrastructure upgrades and grid-enhanc-
ing technologies that enable the deliver-
ability of generating capacity from remote

ability distributions of the magnitudes, fre-
quencies, and durations of potential events that 
affect the availability of—
