COST OF UPGRADES One contractor estimated that the complete cost of all systems, including crankcase ventilation equipment, and engine exhaust gas equipment, as well as, monitoring controls, would be in the range of $50/KW to $55/KW, for a typical diesel generator set. This Contractor has installed emissions controls on aFairbanks-Morse OP at Vinton, IA, and on another engine at Winterset, Iowa. The EPA estimates that total costs will be $50/KW. IAMU says this will be the lower end of the range, and for slower speed equipment could be $100/KW. MMUA says Minnesota municipals have seen costs of $80,000 to $120,000/unit. MMUA says some engine run too slow and too cool, so that additional fuel would be needed to activate the catalyst. Caterpillar has a budgetary price for Caterpillar equipment that is in the range of $30/KW. Emissions control equipment have been installed on 24 Caterpillar engines at Mount Pleasant, Iowa; and two Caterpillars at Bellevue, Iowa. Emissions controls are being installed on Caterpillar equipment at Brooklyn, Iowa, and Montezuma, Iowa. The Southern Minnesota Municipal Power Agency is having emissions controls installed on all their diesels. Many municipals are waiting for further clarification from the EPA before making a decision on emissions controls. Whether the cost is worthwhile, especially for the older equipment, depends on how much value the units are to ERMU, the exhaust temperatures, and the years of remaining useful life. Also, for ERMU, a critical item is whether ERMU can continue to receive capacity credits from GRE, without installing emissions controls.
