IL HB3312

Requires utilities to provide building owners and property managers with aggregated energy and water usage data for their properties, enabling benchmarking of building efficiency performance using tools like ENERGY STAR Portfolio Manager

Establishes aggregation thresholds of 3+ nonresidential accounts or 5+ total accounts to protect individual tenant privacy, with data combined into single collective data points per utility type and time period

Creates tiered compliance timelines based on utility size: large utilities (100,000+ accounts) must comply within 100 days, medium utilities (10,000+ accounts) within 200 days, and small utilities (1,000+ accounts) within 300 days of the Act's effective date

Mandates utilities retain monthly consumption data for at least 7 years (for data from 2022+) and 15 years (for data from 2028+), and provide at least 48 consecutive months of historical data to requesters at no cost

Directs the Illinois Commerce Commission to establish implementing rules within 90 days, adopt standard authorization forms, and evaluate cost recovery requests from utilities after they demonstrate efforts to secure federal or state funding
