(n) By June 30 of each year, beginning in 2025, the Agency
8
shall prepare and publish on its website a report setting
9
forth the actual greenhouse gas emissions from individual
10
units and the aggregate statewide emissions from all units for
11
the prior year.
12

(o) Every 5 years beginning in 2025, the Environmental
13
Protection Agency, Illinois Power Agency, and Illinois
14
Commerce Commission shall jointly prepare, and release
15
publicly, a report to the General Assembly that examines the
16
State's current progress toward its renewable energy resource
17
development goals, the status of CO
2
e and copollutant
18
emissions reductions, the current status and progress toward
19
developing and implementing green hydrogen technologies, the
20
current and projected status of electric resource adequacy and
21
reliability throughout the State for the period beginning 5
22
years ahead, and proposed solutions for any findings. The

1
regarding forecasted resource adequacy and reliability needs,
2
anticipated new generation interconnection, new transmission
3
development or upgrades, and any announced large GHG-emitting
4
unit closure dates and include this information in the report.
5
The report shall be released publicly by no later than
6
December 15 of the year it is prepared. If the Environmental
7
Protection Agency, Illinois Power Agency, and Illinois
8
Commerce Commission jointly conclude in the report that the
9
data from the regional grid operators, the pace of renewable
10
energy development, the pace of development of energy storage
11
and demand response utilization, transmission capacity, and
12
the CO
2
e and copollutant emissions reductions required by
13
subsection (i) or (k-5) reasonably demonstrate that a resource
14
adequacy shortfall will occur, including whether there will be
15
sufficient in-state capacity to meet the zonal requirements of
16
MISO Zone 4 or the PJM ComEd Zone, per the requirements of the
17
regional transmission organizations, or that the regional
18
transmission operators determine that a reliability violation
19
will occur during the time frame the study is evaluating, then
20
the Illinois Power Agency, in conjunction with the
21
Environmental Protection Agency shall develop a plan to reduce
22
or delay CO
2
e and copollutant emissions reductions
23
requirements only to the extent and for the duration necessary
24
to meet the resource adequacy and reliability needs of the
25
State, including allowing any plants whose emission reduction
26
deadline has been identified in the plan as creating a

HB5479
- 13 -
LRB104 20606 AAS 34097 b
1
reliability concern to continue operating, including operating
2
with reduced emissions or as emergency backup where
3
appropriate. The plan shall also consider the use of renewable
4
energy, energy storage, demand response, transmission
5
development, or other strategies to resolve the identified
6
resource adequacy shortfall or reliability violation.
7

(1) In developing the plan, the Environmental
8

Protection Agency and the Illinois Power Agency shall hold
9

at least one workshop open to, and accessible at a time and
10

place convenient to, the public and shall consider any
11

comments made by stakeholders or the public. Upon
12

development of the plan, copies of the plan shall be
13

posted and made publicly available on the Environmental
14

Protection Agency's, the Illinois Power Agency's, and the
15

Illinois Commerce Commission's websites. All interested
16

parties shall have 60 days following the date of posting
17

20

determines that it will resolve the resource adequacy or
21

reliability deficiency identified in the reliability
22

mitigation plan at the least amount of CO
2
e and copollutant
23

emissions, taking into consideration the emissions impacts
24

on environmental justice communities, and that it will

17

mitigation plan within 180 days.
18

(3) The Illinois Commerce Commission shall only
19

approve the plan if the Illinois Commerce Commission
20

determines that it will resolve the resource adequacy or
21

reliability deficiency identified in the reliability
22

mitigation plan at the least amount of CO
2
e and copollutant
23

emissions, taking into consideration the emissions impacts
24

on environmental justice communities, and that it will
25

ensure adequate, reliable, affordable, efficient, and
26

environmentally sustainable electric service at the lowest
