Converting the aging coal-burning Charter Street Heating Plant into one of the greenest facilities of its kind is coming at a price.
The new facility, which received initial approval from the city Plan Commission Monday night, will have the capacity to burn wood chips, corn stalks or other biomass.
But including biomass in the fuel mix has added at least $50 million in cost to the estimated $250 million power plant, the most expensive single project in UW-Madison history.
