IL SB0009

Amends the Public Utilities Act to clarify and restate legislative intent regarding infrastructure investment and modernization programs for electric utilities serving over 1,000,000 customers in Illinois.

Preempts and supersedes certain Illinois Commerce Commission orders in Docket Nos. 11-0721, 12-0001, 12-0293, and 12-0321 that conflict with amendments to Sections 16-108.5 and 4-301.

Modifies performance-based formula rate provisions to specify that utilities must use year-end capital structure (excluding goodwill) and that pension asset return calculations use weighted average cost of long-term debt rather than long-term debt cost of capital.

Allows utilities to file tariffs within 21 days to implement clarified rate calculations and retroactively recover previously unrecovered delivery service costs related to the amended provisions, assessed over 12 monthly billing periods with interest.

Establishes a 12-month compliance period for non-combination utilities to align their infrastructure investment programs with the amended requirements under the clarified rules.
