IL SB3822

Prohibits the Illinois Commerce Commission from allowing public utilities to recover costs for political contributions, gifts to political candidates or parties, lobbying, contributions to trade associations, chambers of commerce, or charitable donations (including utility-managed charities) when setting utility rates.

Makes goodwill or institutional advertising a non-recoverable expense for gas, electric, water, and sewer utilities, meaning shareholders rather than ratepayers must bear these costs.

Limits recoverable charitable donations to energy assistance programs only; donations for general public welfare, religious, scientific, or educational purposes become shareholder expenses rather than costs passed to consumers.

Declares attorney and expert witness fees incurred by utilities to prepare and litigate rate cases as non-recoverable expenses that cannot be passed on to ratepayers.

Requires utilities filing rate increase requests to deposit up to $500,000 (half of reported rate case legal expenses) into the Consumer Intervenor Compensation Fund, with these deposits also being non-recoverable from ratepayers.
