1 participant in a regional transmission organization
2 receives notice that the regional transmission
3 organization has determined that continued operation of
4 the unit is required, the unit may continue operating
5 until the issue identified by the regional transmission
6 organization is resolved. The owner or operator of the
7 unit must cooperate with the regional transmission
8 organization in resolving the issue and must reduce its
9 emissions to zero, consistent with the requirements under

19 capacity of an emergency backup unit if approved by the
20 Illinois Commerce Commission.
21 (m) No variance, adjusted standard, or other regulatory
22relief otherwise available in this Act may be granted to the
23emissions reduction and elimination obligations in this
24Section.
25 (n) By June 30 of each year, beginning in 2025, the Agency
26shall prepare and publish on its website a report setting

HB3935- 12 -LRB103 28358 CPF 54738 b
1forth the actual greenhouse gas emissions from individual
2units and the aggregate statewide emissions from all units for
3the prior year.
4 (o) Every 5 years beginning in 2025, the Environmental
5Protection Agency, Illinois Power Agency, and Illinois
6Commerce Commission shall jointly prepare, and release
7publicly, a report to the General Assembly that examines the
8State's current progress toward its renewable energy resource
9development goals, the status of CO2e and copollutant
10emissions reductions, the current status and progress toward
11developing and implementing green hydrogen technologies, the
12current and projected status of electric resource adequacy and
13reliability throughout the State for the period beginning 5
14years ahead, and proposed solutions for any findings. The
15Environmental Protection Agency, Illinois Power Agency, and
16Illinois Commerce Commission shall consult PJM
17Interconnection, LLC and Midcontinent Independent System
18Operator, Inc., or their respective successor organizations
19regarding forecasted resource adequacy and reliability needs,
20anticipated new generation interconnection, new transmission
21development or upgrades, and any announced large GHG-emitting
22unit closure dates and include this information in the report.
23The report shall be released publicly by no later than
24December 15 of the year it is prepared. If the Environmental
25Protection Agency, Illinois Power Agency, and Illinois
26Commerce Commission jointly conclude in the report that the

HB3935- 13 -LRB103 28358 CPF 54738 b
1data from the regional grid operators, the pace of renewable
2energy development, the pace of development of energy storage
3and demand response utilization, transmission capacity, and
4the CO2e and copollutant emissions reductions required by
5subsection (i) or (k-5) reasonably demonstrate that a resource
6adequacy shortfall will occur, including whether there will be
7sufficient in-state capacity to meet the zonal requirements of
8MISO Zone 4 or the PJM ComEd Zone, per the requirements of the
9regional transmission organizations, or that the regional
10transmission operators determine that a reliability violation
11will occur during the time frame the study is evaluating, then
12the Illinois Power Agency, in conjunction with the
13Environmental Protection Agency shall develop a plan to reduce
14or delay CO2e and copollutant emissions reductions
15requirements only to the extent and for the duration necessary
16to meet the resource adequacy and reliability needs of the
17State, including allowing any plants whose emission reduction
18deadline has been identified in the plan as creating a
19reliability concern to continue operating, including operating
20with reduced emissions or as emergency backup where
21appropriate. The plan shall also consider the use of renewable
22energy, energy storage, demand response, transmission
23development, or other strategies to resolve the identified
24resource adequacy shortfall or reliability violation.
25 (1) In developing the plan, the Environmental
26 Protection Agency and the Illinois Power Agency shall hold

HB3935- 14 -LRB103 28358 CPF 54738 b
1 at least one workshop open to, and accessible at a time and
2 place convenient to, the public and shall consider any
3 comments made by stakeholders or the public. Upon
4 development of the plan, copies of the plan shall be
5 posted and made publicly available on the Environmental
6 Protection Agency's, the Illinois Power Agency's, and the
7 Illinois Commerce Commission's websites. All interested
8 parties shall have 60 days following the date of posting
9 to provide comment to the Environmental Protection Agency
10 and the Illinois Power Agency on the plan. All comments
11 submitted to the Environmental Protection Agency and the
12 Illinois Power Agency shall be encouraged to be specific,
13 supported by data or other detailed analyses, and, if
14 objecting to all or a portion of the plan, accompanied by
15 specific alternative wording or proposals. All comments
16 shall be posted on the Environmental Protection Agency's,
17 the Illinois Power Agency's, and the Illinois Commerce
18 Commission's websites. Within 30 days following the end of
19 the 60-day review period, the Environmental Protection
20 Agency and the Illinois Power Agency shall revise the plan
21 as necessary based on the comments received and file its
22 revised plan with the Illinois Commerce Commission for
23 approval.
24 (2) Within 60 days after the filing of the revised
25 plan at the Illinois Commerce Commission, any person
26 objecting to the plan shall file an objection with the

HB3935- 15 -LRB103 28358 CPF 54738 b
1 Illinois Commerce Commission. Within 30 days after the
2 expiration of the comment period, the Illinois Commerce
3 Commission shall determine whether an evidentiary hearing
4 is necessary. The Illinois Commerce Commission shall also
5 host 3 public hearings within 90 days after the plan is
6 filed. Following the evidentiary and public hearings, the
7 Illinois Commerce Commission shall enter its order
8 approving or approving with modifications the reliability
9 mitigation plan within 180 days.
10 (3) The Illinois Commerce Commission shall only
11 approve the plan if the Illinois Commerce Commission
12 determines that it will resolve the resource adequacy or
13 reliability deficiency identified in the reliability
14 mitigation plan at the least amount of CO2e and copollutant
15 emissions, taking into consideration the emissions impacts
16 on environmental justice communities, and that it will
17 ensure adequate, reliable, affordable, efficient, and
18 environmentally sustainable electric service at the lowest
19 total cost over time, taking into account the impact of
20 increases in emissions.
21 (4) If the resource adequacy or reliability deficiency
22 identified in the reliability mitigation plan is resolved
23 or reduced, the Environmental Protection Agency and the
24 Illinois Power Agency may file an amended plan adjusting
25 the reduction or delay in CO2e and copollutant emission
26 reduction requirements identified in the plan.
