Northern Illinois Gas "reluctantly" has
withdrawn its performance-based rate proposal from the Illinois commission. Under the proposal, NIG would have compared its total annual gas supply costs against a market-based benchmark, and the difference would have been shared between NIG and its customers. Presently, natural gas supply costs are recovered directly from customers without mark-up.
NIG had filed its proposal in response to an amendment to the Illinois Public Utilities Act authorizing the commission to approve performance-based rates on an experimental basis.
