Synopsis As Introduced Amends the Public Utilities Act. Provides that the term "eligible renewable electrical generating facility" includes a generator powered by agricultural residues, untreated and unadulterated wood waste, landscape trimmings, and livestock manure. Provides that for eligible customers (rather than only residential customers), the measuring of the flow of electricity in both directions at the same rate shall typically be accomplished through use of a single, bi-directional meter. Deletes language with respect to net metering for non-residential customers. Provides that the electricity provider shall continue to carry over any excess kilowatt-hour credits earned and apply those credits to subsequent billing periods to offset any customer-generator consumption in those billing periods until all credits are used or until service is terminated (instead of or until the end of the annualized period). Deletes language concerning (1) net metering for certain non-residential customers, (2) specified charges, (3) specified customer credits, and (4) the number of eligible customers for net metering. Provides that the meter aggregation shall be subject to the terms and conditions approved by the Illinois Commerce Commission in a proceeding establishing the rules applicable to meter aggregation under specified provisions, which shall commence no less than 180 days after the effective date of the amendatory Act and be completed within 365 days after the effective date of the amendatory Act. Effective immediately.
