Under a revised "Power Block First" proposal for the Taylorville Energy Center, Illinois electricity customers could save an estimated $437.7 million over a 20-year period, including more than $250.6 million in the plant's first five years of operation, according to a rate impact analysis conducted by Pace Global LLC, a Siemens business.
As TEC's power capacity is bid into the PJM auction in future years, hundreds of millions in additional savings for ComEd customers could also be realized because of lower resulting auction prices.
