body
DEPARTMENT: Electric Utility
SUBMITTED BY: Brian Groth, Director of Electric Utilities
BOARD/COMMISSION REVIEW:
N/A
PURPOSE:
The purpose of this memorandum is to provide the Public Utility Advisory Board (PUAB) with a status update on market and regulatory changes impacting the City of Naperville's Electric Utility.
Key regulatory drivers for 2026 include:
? Illinois Resource Adequacy Study Findings Released
? Illinois Clean and Reliable Grid Affordability Act (CRJA) Passage
? PJM Delivery Year 2027/2028 Capacity Auction Results
DISCUSSION:

The Climate and Equitable Jobs Act passed by the State of Illinois Legislature in 2021

? Load growth is accelerating while coal, gas and oil powered generation units are planning to retire across the grid
? Natural gas-fired generation is slow to come online due to long equipment lead times as well as permitting and siting issues
? Renewables and batteries have lower effective capacity values than thermal resources requiring more resources to be put on the grid.
? Long interconnection queues and transmission constraints are common for development of new generation projects.
Due to the study's finding that neither the ComEd zone in PJM nor Zone 4 in MISO have enough resources to meet 2030 requirements it is likely that the State will become a net importer of power.
There are concerns with this concept as PJ...
